企业开发 2018-09-12 23:08:47 阅读次数: 0

实验说明：

服务角色 IP 系统 需安装
主控机 192.168.24.128 centos7 ansible
A受控机 192.168.24.130 centos7 nginx
B受控机 192.168.24.131 centos7 mysql
C受控机 192.168.24.132 centos7 php-fpm

实验需求：

在主控机上使用自动化运维工具ansible在A受控机上安装nginx，在B受控机上安装mysql，在C受控机上安装php-fpm，实现lnmp构架

实验步骤

在主控机上安装ansible

安装yum源

[root@linfan ~]# cd /etc/yum.repos.d/ 
root@linfan yum.repos.d]# curl -o 163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@linfan yum.repos.d]# sed -i 's/\$releasever/7/g' 163.repo
[root@linfan yum.repos.d]# sed -i 's/^enabled=.*/enabled=1/g' 163.repo
[root@linfan yum.repos.d]#  yum -y install epel-release

安装ansible

[root@linfan yum.repos.d]# yum -y install ansible ansible-doc

查看ansible的版本

[root@linfan ~]# ansible --version
ansible 2.6.3
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

编辑nginx配置文件

在主控机上编辑nginx配置文件

 vim /etc/nginx/nginx.conf
//编辑以下内容

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
        # location ~ \.php$ {

        # }

         location ~ \.php$ {
             proxy_pass   http://php;
             root           /usr/share/nginx/html;
             fastcgi_pass   php;

             include        fastcgi_params;
        }

将修改后的文件传输到A主控机上
