一、 总览

在这里插入图片描述
1.系统初始化:指的是操作系统安装完毕后，都需要使用到的初始配置，比如安装基础软件、调整内核参数、设置yum仓库等。
⒉.功能模块:指的是生产使用到的应用软件，比如Nginx、PHP、Haproxy、Keepalived等这类应用服务的安装和管理，每一个功能我们创建一个roles角色来存放，我们把这个目录的集合称之为“功能模块"。
3.业务模块:在功能模块中我们编写了大量基础的功能状态，在业务层面直接进行引用，所以功能模块就是尽可能的全、而且独立。
而业务模块，不同的业务类型就可以调用不同的roles，使得每个业务使用自己独特的配置文件。最终在site.yml里面我们指定业务的状态即可。

ansible目录准备

[root@manager /]# mkdir /ansible/roles -p
[root@manager /]# cd ansible/roles/
[root@manager roles]# cp /etc/ansible/hosts ./
[root@manager roles]# cp /etc/ansible/ansible.cfg ./

ansible.cfg文件，将facts缓存在本地的redis中

[root@manager roles]# cat ansible.cfg 
inventory  = ./host
host_key_checking = False
gathering = smart  
fact_caching_timeout = 86400
fact_caching = redis
fact_caching_connection = 172.16.1.62:6379
forks = 50

hosts主机清单文件：

[root@manager roles]# cat hosts
[routes]
172.16.1.200

[dnsservers]
172.16.1.91
172.16.1.92

[lbservers]
172.16.1.3
172.16.1.4

[proxyservers]
172.16.1.5
172.16.1.6

测试连通性，如果不连通则说明没有推送公钥，需要事先把ansible主机秘钥推送一份给各个节点。

[root@manager roles]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.51
[root@manager roles]# ansible all -m ping

[root@manager roles]# ansible all --list-host # 查看当前hosts所有主机
  hosts (14):
    172.16.1.7
    172.16.1.8
    172.16.1.9
    172.16.1.31
    172.16.1.3
    172.16.1.4
    172.16.1.5

    172.16.1.200
    172.16.1.32
    172.16.1.91
    172.16.1.92
    172.16.1.51



[root@manager roles]# mkdir group_vars # 创建全局变量文件
[root@manager roles]# touch group_vars/all

初始化网络

[root@manager roles]# cat network_init.yml 
- hosts: all:!dnsservers:!routes
  tasks:
  
    - name: delete default gateway
      lineinfile:
        path:  /etc/sysconfig/network-scripts/ifcfg-eth1
        regexp: '^GATEWAY='
        state: absent

    - name: add new gateway
      lineinfile:
        path:  /etc/sysconfig/network-scripts/ifcfg-eth1
        line: GATEWAY=172.16.1.200

    - name: delete default dns
      lineinfile:
        path:  /etc/sysconfig/network-scripts/ifcfg-eth1
        regexp: '^DNS'
        state: absent

    - name: add new dns
      lineinfile:
        path:  /etc/sysconfig/network-scripts/ifcfg-eth1
        line: DNS=223.5.5.5

    - name: restart network
      systemd:
        name: network
        state: restarted

查看是否符合预期

[root@manager roles]# ansible-playbook network_init.yml
[root@manager roles]# ansible all -m shell -a "cat /etc/sysconfig/network-scripts/ifcfg-eth1 | grep DNS"
[root@manager roles]# ansible all -m shell -a "cat /etc/sysconfig/network-scripts/ifcfg-eth1 | grep GATEWAY"

二、ansible基础模块安装

当我们的服务器上架并安装好操作系统后，都会有一些基础的操作，建议将所有服务器都会涉及的基础配置都存放在名为roles中的base 下。我们称其为“初始化模块”
1.关闭防火墙Firewalld selinux
2.创建统一用户www, uid为666 gid为666
3.添加base、 epel仓库
4.特定主机需要添加特定的仓库源nginx 、php、 mysql、zabbix、 elk …
5.安装基础软件包, rsync、 nfs-utils、 net-tools lrzsz、 wget、 unzip、 vim、 tree. …
6.内核升级\内核参数调整\文件描述符调整

2.1 关闭防火墙

[root@manager roles]# mkdir base/{
    
    tasks,templates,files,handlers} -p

[root@manager roles]# cat  base/tasks/firewalld.yml
- name: disable selinux 
  selinux:
    state: disabled

- name: disable firewall
  systemd:
    name: firewalld
    state: stopped
    enabled: no

2.2 创建统一用户

[root@manager roles]# cat base/tasks/user.yml
- name: create uniform user group www
  group:
    name: "{
    
    { all_group }}"
    gid: "{
    
    { gid }}"
    system: yes
    state: present

- name: create uniform user www
  user:
    name: "{
    
    { all_user }}"
    group: "{
    
    { all_group }}"
    uid: "{
    
    { uid }}"
    system: yes
    state: present

2.3 创建统一仓库

[root@manager roles]# cat base/tasks/yum_repository.yml 
- name: Add Base Yum Repository
  yum_repository:
    name: base
    description: Base Aliyun Repository
    baseurl: http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
    gpgcheck: yes
    gpgkey: http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

    baseurl: https://repo.ius.io/archive/7/$basearch/
    gpgcheck: yes
    gpgkey: https://repo.ius.io/RPM-GPG-KEY-IUS-7

2.4 所有主机需要安装基础yum包

[root@manager roles]# cat base/tasks/yum_pkg.yml 
- name: Installed Packages All
  yum:
    name: "{
    
    { item }}"
    state: present
  loop:
      - rsync
      - nfs-utils
      - net-tools
      - wget
      - tree
      - lrzsz

  pam_limits:
    domain: "*"
    limit_type: "{
    
    { item.limit_type }}"
    limit_item: "{
    
    { item.limit_item }}"
    value: "{
    
    { item.value  }}"
  loop:
    - {
    
     limit_type: 'soft', limit_item: 'nofile',value: '100000' }
    - {
    
     limit_type: 'hard', limit_item: 'nofile',value: '100000' }

2.9 调整内核参数 sysctl

[root@manager roles]# ansible-playbook top.yml

三、 安装具体的服务

3.1 nfs安装

root@manager roles]# mkdir nfs-server/{
    
    tasks,templates,handlers,files} -p
[root@manager roles]# cat nfs-server/tasks/main.yml 
- name: create nfs share  directory # 创建两个共享目录
  file:
    path: "{
    
    { item }}"
    owner: "{
    
    {all_user}}"
    group: "{
    
    {all_group}}"
    state: directory
    mode: "0755"
    recurse: yes
  loop:
    - "{
    
    {nfs_share_blog}}"
    - "{
    
    {nfs_share_zrlog}}"


- name: configure nfs server  
  template:
    src: exports.j2
    dest: /etc/exports

  notify: restart nfs server



- name: start nfs server
  systemd:
    name: nfs
    state: started
    enabled: yes


[root@manager roles]# cat nfs-server/templates/exports.j2 
{
    
    {
    
     nfs_share_blog }} {
    
    {
    
     nfs_allow_ip_range }}(rw,sync,all_squash,anonuid={
    
    {
    
     uid }},anongid={
    
    {
    
     gid }})
{
    
    {
    
     nfs_share_zrlog }} {
    
    {
    
     nfs_allow_ip_range }}(rw,sync,all_squash,anonuid={
    
    {
    
     uid }},anongid={
    
    {
    
     gid }})



[root@manager roles]# cat nfs-server/handlers/main.yml 
- name: restart nfs server
  systemd:

运行

[root@manager roles]# cat top.yml 
#- hosts: all
#  roles:
#    - role: base


- hosts: nfsservers
  roles:
    - role: nfs-server



[root@manager roles]# ansible-playbook top.ym

3.2 rsync 安装

默认启动用www 用户，且初始化阶段已经安装了rsync。

root@manager roles]# mkdir rsync-server/{
    
    tasks,templates,handlers,files} -p

[root@manager roles]# cat rsync-server/tasks/main.yml 
[root@manager roles]# cat rsync-server/tasks/main.yml 
- name: copy virtual user passwd file
  copy:
    content: "{
    
    { rsync_virtual_user }}:{
    
    { rsync_virtual_passwd }}"
    dest: "{
    
    { rsync_virtual_path }}"
    mode: "0600"



- name: create rsync module dir
  file: 
    path: "{
    
    { item }}"
    owner: "{
    
    { all_user }}"
    group: "{
    
    { all_group }}"
    state: directory
    recurse: yes

  loop:
    - "{
    
    { rsync_module_path1 }}" # 创建两个目录用于两个项目
    - "{
    
    { rsync_module_path2 }}"


- name: configure rsync
  template:
    src: rsyncd.conf.j2
    dest: /etc/rsyncd.conf
  notify: restart rsyncd


- name: start rsyncd
  systemd:
    name: rsyncd
    state: started
    enabled: yes


root@manager roles]# cat rsync-server/templates/rsyncd.conf.j2 
uid = {
    
    {
    
    all_user}}
gid = {
    
    {
    
    all_group}}
port = {
    
    {
    
    rsync_port}}
fake super = yes
use chroot = no
max connections = {
    
    {
    
    rsync_max_conn}}
timeout = 600
ignore errors
read only = false
list = true
log file = /var/log/rsyncd.log
auth users = {
    
    {
    
    rsync_virtual_user}}
secrets file = {
    
    {
    
     rsync_virtual_path}}
# 创建两个模块用于两个项目
[{
    
    {
    
    rsync_module_name1}}]
path = {
    
    {
    
    rsync_module_path1}}

[{
    
    {
    
    rsync_module_name2}}]
path = {
    
    {
    
    rsync_module_path2}}


[root@manager roles]# cat rsync-server/handlers/main.yml 
- name: restart rsyncd
  systemd:
    name: rsyncd

3.3 sersync实时同步

监测nfs端的共享目录，如果有变化实时同步到rsync备份服务器。
安装sersync 、rsync、 inotify-tools

[root@manager roles]# cat sersync-server/tasks/main.yml 
- name: install inotify-tools
  yum:
    name: inotify-tools
    state: present


- name: unarchive sersync.tar.gz to remote
  unarchive:
    src: sersync2.5.4_64bit_binary_stable_final.tar.gz
    dest: "{
    
    { rsync_path }}"



- name: configure confxml.xml.j2 to remote
  template: 
    src: confxml1.xml.j2
    dest: "{
    
    { rsync_path }}/GNU-Linux-x86/confxml1.xml"

- name: configure confxml.xml1.j2 to remote

3.12 配置route

  1. 开启DNAT
  2. 开启SNAT
  3. 开启forword (基础阶段已经开启)
[root@manager roles]# cat route/tasks/main.yml

三 、部署wordpress 博客系统

3.1 web站点层

0.备份以前原有数据库
   [root@localhost ~]# mysqldump -B wordpress >/tmp/wordpress.sql
1.创建存放项目代码的目录（/webcode）
2.解压本地打包好的wordpress 项目到远程指定的代码目录(里面包含连接数据配置信息，避免跳出向导页面)
3.推送nginx代理配置文件（要与首次连接数据库成功时的地址和端口保持一致，因为其已经写入了数据库，否则会有未知错误）
4.创建数据库wordpress
5.恢复数据库之前备份出来的sql文件
（注意，建议4，5 步，在数据库初始化阶段（安装配置阶段）完成，因为实际生产环境中数据库和数据本来就已经配置好，运维只需要连接即可。否则需要把wordpress.sql 分别推送到web站点服务器指定目录，例如 /tmp/wordpress.sql）,并且要在站点安装mariadb客户端，才能成功。 
[root@manager roles]# mkdir blog-web/{
    
    tasks,meta,templates,handlers,files} -p


[root@manager roles]# cat wordpress-web/tasks/main.yml 
- name: create code directory
  file:
    path: "{
    
    { wordpress_code_path }}"
    owner: "{
    
    { all_user }}"
    group: "{
    
    { all_group }}"
    mode: "0755"
    state: directory
    recurse: yes


- name: unarchive wordpress_web_code to remote
  unarchive:
    src: wordpress.tar.gz
    dest: "{
    
    { wordpress_code_path }}" 
    owner: "{
    
    { all_user }}"
    group: "{
    
    { all_group }}"
    mode: "0755"
    creates: "{
    
    { wordpress_code_path }}/wordpress/wp-config.php" # 避免重复解压




- name: create wordpress nginx config
  template: 
    src: wordpress.conf.j2 
    dest: "{
    
    { nginx_include_dir }}/wordpress.conf"
  notify: restart nginx server # 在安装nginx阶段已经定义，此处可以不用写handlers

# 设置挂载点
- name: configure mount nfs
  mount:
    src: "172.16.1.32:{
    
    { nfs_share_blog }}"
    path: "{
    
    { wordpress_code_path}}/wordpress/wp-content/uploads/"
    fstype: nfs
    opts: defaults
    state: mounted  


# 以下四部已经在安装mariadb服务器时候创建，放在这是因为提供思路，本身不用执行

#-name: 推送wordpress.sql 到web站点指定目录
# 略

#- name: web站点安装mariadb客户端
# 略

#- name: Create a new database with name 'wordpress'
#  mysql_db:

#      login_password: "{
     
     { mysql_super_user_passwd }}"
#      name: wordpress
#      state: present
#
#- name: Import file.sql similar to mysql -u <username> -p <password> < hostname.sql

# 依赖
[root@manager roles]# cat wordpress-web/meta/main.yml 
dependencies:
  - {
    
     role: nginx-server }
  - {
    
     role: php-fpm }



[root@manager roles]# cat wordpress-web/templates/wordpress.conf.j2

3.2 七层负载均衡 haproxy, 备用nginx

如果架构只做七层负载均衡，则需要依赖keepalived, 如果前面还需要接入四层负载均衡，则此处只做集群，不需要keepalived。在四层上面接入keepalived即可。

[root@manager roles]# mkdir wordpress-proxy/{
    
    tasks,handlers,templates,meta} -p


[root@manager roles]# cat wordpress-proxy/tasks/main.yml 
- name: create https key dir
  file:
    path: "{
    
    { https_key_dir }}"
    state: directory

- name: copy https key_per 
  copy:
    src: blog_key.pem.j2
    dest: "{
    
    { https_key_dir }}/blog_key.pem"



- name: wordpress haproxy configure file
  template:
    src: haproxy.cfg.j2
    dest: "{
    
    { haproxy_include_path }}/wordpress_haproxy.cfg"
  notify: restarted haproxy server


[root@manager roles]# cat wordpress-proxy/templates/haproxy.cfg.j2 
frontend web
	bind *:{
    
    {
    
     haproxy_port }}
	bind *:443 ssl crt {
    
    {
    
      https_key_dir }}/blog_key.pem 
	mode http

	#acl 规则将blog 调度到blog_cluster 
	acl blog_domain hdr(host) -i {
    
    {
    
     wordpress_domain }}
	redirect scheme https code 301 if !{
    
     ssl_fc } blog_domain
	use_backend blog_cluster if blog_domain


backend blog_cluster
	balance roundrobin
	option httpchk HEAD / HTTP/1.1\r\nHost:\ {
    
    {
    
     wordpress_domain }}
	{
    
    % for host in groups["webservers"] %}
	server {
    
    {
    
     host }} {
    
    {
    
     host }}:{
    
    {
    
     nginx_http_listen_port }} check port {
    
    {
    
      nginx_http_listen_port }} inter 3s rise 2 fall 3
	{
    
    % endfor %}

# 依赖
[root@manager roles]# cat wordpress-proxy/meta/main.yml

     role: haproxy }


#参数
#wordpress haproxy 
haproxy_port: 80
https_key_dir: /ssl

# 证书
[root@manager roles]# ls wordpress-proxy/files/blog_key.pem.j2 
wordpress-proxy/files/blog_key.pem.j2


# 证书生成方式：
1.准备证书 需要将证书追加到一个文件中
[root@proxy01 ~]# cat /etc/nginx/ssl_key/6152893_blog.bertwu.online.pem > /ssl/blog_key.pem
[root@proxy01 ~]# cat /etc/nginx/ssl_key/6152893_blog.bertwu.online.key >> /ssl/blog_key.pem

四、部署java项目 zrlog

4.1 安装 tomcat

1.下载 rpm 格式jdk解压到remote
2.yum本地安装jdk
3.远程创建/soft 目录
4.远程解压tomcat到/soft目录
5.制作软连接
6.推送tomcat启停文件
7.推送配置文件 权限0600
8.启动tomcat

[root@manager roles]# cat tomcat/tasks/main.yml

3.# 事先把代码目录已经打包好了
[root@manager roles]# ls zrlog-web/files/zrlog.tar.gz 
zrlog-web/files/zrlog.tar.gz

4.# 依赖
[root@manager roles]# cat zrlog-web/meta/main.yml 
dependencies:
  - {
    
     role: tomcat }

5.# 参数
[root@manager roles]# cat group_vars/all 
# zrlog
zrlog_code_path: /webcode
tomcat_port: 8080
zrlog_domain: zrlog.bertwu.online

4.3 部署七层 zrlog-proxy 用haproxy做代理

如果架构只做七层负载均衡，则需要依赖keepalived, 如果前面还需要接入四层负载均衡，则此处只做集群，不需要keepalived。在四层上面接入keepalived即可。

1.创建目录
[root@manager roles]# mkdir zrlog-proxy/{
    
    tasks,templates,handlers,meta,files} -p

2.主配置文件
[root@manager roles]# cat zrlog-proxy/tasks/main.yml 
- name: create https key dir
  file: 
    path: "{
    
    { https_key_dir }}"
    state: directory


- name: copy https key_per to remote
  copy:
    src: zrlog_key.pem.j2
    dest: "{
    
    { https_key_dir }}/zrlog_key.pem"



- name: configuer zrlog haproxy flie 
  template:
    src: haproxy.cfg.j2
    dest: "{
    
    { haproxy_include_path }}/zrlog_haproxy.cfg"
  notify: restarted haproxy server

3.haproxy 配置文件
[root@manager roles]# cat zrlog-proxy/templates/haproxy.cfg.j2 
frontend webs # 多站点时候这个名字好像不能重复
	bind *:80
	bind *:443 ssl crt {
    
    {
    
     https_key_dir }}/zrlog_key.pem 
	mode http

	# acl 规则将blog 调度到blog_cluster 
	acl zrlog_domain hdr(host) -i {
    
    {
    
     zrlog_domain }}
	redirect scheme https code 301 if !{
    
     ssl_fc } zrlog_domain
	use_backend zrlog_cluster if zrlog_domain


backend zrlog_cluster
	balance roundrobin
	option httpchk HEAD / HTTP/1.1\r\nHost:\ {
    
    {
    
     zrlog_domain }}
	{
    
    % for host in groups['webservers'] %}
	server {
    
    {
    
     host }} {
    
    {
    
     host }}:{
    
    {
    
     tomcat_port }} check port {
    
    {
    
     tomcat_port }} inter 3s rise 2 fall 3
	{
    
    % endfor %}

4.依赖
[root@manager roles]# cat zrlog-proxy/meta/main.yml 
dependencies:
  - {
    
     role: haproxy }

5.证书目录
[root@manager roles]# ls zrlog-proxy/files/zrlog_key.pem.j2 
zrlog-proxy/files/zrlog_key.pem.j2

6.证书生成方式，在 证书目录下追加生成一个文件
[root@proxy01 ssl_key]# cat ./6181156_zrlog.bertwu.online.pem >/tmp/zrlog_key.pem
[root@proxy01 ssl_key]# cat ./6181156_zrlog.bertwu.online.key >>/tmp/zrlog_key.pem

五、部署phpmyadin项目

5.1 web端部署phpmyadmin

1.七层负载均衡为nginx, 四层为lvs
2.后端web 节点 phpmyadmin代码打包，解压到web端，因为里面已经包含了连接数据库文件。
3.依赖php-fpm ，连接redis的配置在安装php时候已经配置完毕。一个文件为/etc/php.ini,里面包含连接redis的信息。一个为/etc/php-fpm.d/www.conf，让配置session存储的方式（数据库或文件）
4.需要依赖php-fpm 和nginx-server

[root@manager roles]# mkdir phpmyadmin/{
    
    tasks,templates,handlers,files,meta} -p

1.主文件
[root@manager roles]# cat phpmyadmin/tasks/main.yml 
- name: create code path
  file: 
    path: "{
    
    { phpmyadmin_code_path }}"
    state: directory
    owner: "{
    
    { all_user }}"
    group: "{
    
    { all_group }}"
    mode: "0755"
    recurse: yes


- name: unarchive code package to remote
  unarchive:
    src: phpmyadmin.tar.gz
    dest: "{
    
    { phpmyadmin_code_path }}"
    creates: "{
    
    { phpmyadmin_code_path }}/phpmyadmin/config.inc.php "

- name: configuer nginx proxy file
  template: 
    src: phpmyadmin.conf.j2
    dest: "{
    
    { nginx_include_dir }}/phpmyadmin.conf"
  notify: restart nginx server


2.依赖
[root@manager roles]# cat phpmyadmin/meta/main.yml 
dependencies:
  - {
    
     role: php-fpm }
  - {
    
     role: nginx-server  }

3. nginx代理配置文件
[root@manager roles]# cat phpmyadmin/templates/phpmyadmin.conf.j2 
server {
    
    
	listen {
    
    {
    
     phpmyadmin_nginx_listen_port }};
	server_name {
    
    {
    
     phpmyadmin_domain }};
	client_max_body_size 100m;
	root {
    
    {
    
     phpmyadmin_code_path }}/phpmyadmin;
	charset utf-8;
	location / {
    
    
		index index.php index.html;
	}
	location ~* .*\.php$ {
    
    
		fastcgi_pass 127.0.0.1:9000;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		include /etc/nginx/fastcgi_params;
	 	fastcgi_param HTTPS {
    
    {
    
     php_https_state }};
 
	}
}  

4. 代码包,需要提前打包
[root@manager roles]# ls phpmyadmin/files/
phpmyadmin.tar.gz

5.参数
# phpmyadmin
phpmyadmin_code_path: /webcode
phpmyadmin_domain: phpmyadmin.bertwu.online
phpmyadmin_nginx_listen_port: 80
php_https_state: "off"    # 当前端开启https时候将其改为on

5.2 七层负载均衡上用nginx（备用haproxy）

注意，需要手动停止先前运行的haproxy，否则（80和443）端口冲突导致nginx启动失败。或者nginx和haproxy监听不同的端口，前端lvs代理后端在重新定义一组端口集群，比较麻烦。而且生产环境中七层负载均衡也没有haproxy和nginx同时使用。本次纯粹是为了实验。

[root@manager roles]# mkdir phpmyadmin-proxy/{
    
    tasks,templates,meta,files} -p
1.主文件
root@manager roles]# cat phpmyadmin-proxy/tasks/main.yml 
- name: create certificate dir
  file:
    path: "{
    
    { ssl_key_dir }}"
    state: directory

- name: unarchive ssl_key to ssl_key_dir
  unarchive:
    src: 6386765_phpmyadmin.bertwu.online_nginx.zip
    dest: "{
    
    { ssl_key_dir }}"
    creates: "{
    
    { ssl_key_dir }}/6386765_phpmyadmin.bertwu.online.key"


- name: copy proxy_params file
  template:
    src: proxy_params.j2
    dest: /etc/nginx



- name: configure nginx file
  template:
    src: phpmyadmin.conf.j2
    dest: "{
    
    { nginx_include_dir }}/phpmyadmin.conf"
  notify: restart nginx server

2.依赖
[root@manager roles]# cat phpmyadmin-proxy/meta/main.yml 
dependencies:
  - {
    
     role: nginx-server }


3.# 七层负载均衡代理相关参数

1.wordpress 七层负载均衡选用nginx配置语法：

[root@proxy01 conf.d]# cat wordpress.conf 
upstream wdblog {
    
    
	server 172.16.1.7:80;
	server 172.10.1.8:80;
	server 172.10.1.9:80;
}

server {
    
    
	listen 443 default ssl;
	server_name blog.bertwu.online;
	ssl_certificate ssl_key/6188098_blog.bertwu.online.pem;
	ssl_certificate_key ssl_key/6188098_blog.bertwu.online.key;

	location / {
    
    
		proxy_pass http://wdblog;
		include proxy_params;
