Java#Tomcat single instance site deployment

1. Install JDK&Tomcat

Turn off the firewall and selinux

安装Tomcat & JDK

安装时候选择tomcat软件版本要与程序开发使用的版本一致。jdk版本要进行与tomcat保持一致。

###### 1、系统环境说明

关闭防火墙和selinux

```shell
[root@java-tomcat1 ~]# getenforce 
Disabled
[root@java-tomcat1 ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

Install JDK

上传jdk1.8到服务器。安装jdk
[root@java-tomcat1 ~]# tar xzf jdk-8u191-linux-x64.tar.gz -C /usr/local/
[root@java-tomcat1 ~]# cd /usr/local/
[root@java-tomcat1 local]# mv jdk1.8.0_191/ java
设置环境变量:
[root@java-tomcat1 local]# vim /etc/profile.d/jdk.sh
export JAVA_HOME=/usr/local/java   #指定java安装目录
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH    #用于指定java系统查找命令的路径
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar  #类的路径，在编译运行java程序时，如果有调用到其他类的时候，在classpath中寻找需要的类。
检测JDK是否安装成功:
[root@java-tomcat1 local]# source /etc/profile.d/jdk.sh
[root@java-tomcat1 local]# java -version 
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

Install Tomcat

[root@java-tomcat1 ~]# mkdir /data/application -p
[root@java-tomcat1 ~]# cd /usr/src/
[root@java-tomcat1 src]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.49/bin/apache-tomcat-8.5.49.tar.gz
[root@java-tomcat1 src]# tar xzf apache-tomcat-8.5.49.tar.gz -C /data/application/
[root@java-tomcat1 src]# cd /data/application/
[root@java-tomcat1 application]# mv apache-tomcat-8.5.49/ tomcat
设置环境变量:
[root@java-tomcat1 application]# vim /etc/profile
#这里没有把Tomcat的启动、关闭命令、添加到环境变量里面，原因是方便给实现多实例部署
export TOMCAT_HOME=/data/application/tomcat   #指定tomcat的安装目录
[root@java-tomcat1 application]# source  /etc/profile
查看tomcat是否安装成功:
[root@java-tomcat1 tomcat]# /data/application/tomcat/bin/version.sh
Using CATALINA_BASE:   /data/application/tomcat
Using CATALINA_HOME:   /data/application/tomcat
Using CATALINA_TMPDIR: /data/application/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /data/application/tomcat/bin/bootstrap.jar:/data/application/tomcat/bin/tomcat-juli.jar
Server version: Apache Tomcat/8.5.49
Server built:   Nov 17 2019 18:45:30 UTC

Access the management page

Click the button to be denied access.

Follow the prompts to configure the following

[root@tomcat ~]# vim /usr/local/tomcat/conf/tomcat-users.xml 
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<user username="user" password="password" roles="tomcat,manager-gui,manager-script,admin-gui,admin-script"/>

[root@tomcat ~]# vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml 
[root@tomcat ~]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml 
# 修改权限，可以允许所有，可以允许ip，支持正则
# 内容均修改为如下图片，然后重启tomcat

Visit after restart

Add a little Tomcat configuration file

2、server.xml配置文件

<?xml version='1.0' encoding='utf-8'?>

 4、Connector主要参数说明

```shell
port:指定服务器端要创建的端口号，并在这个端口监听来自客户端的请求。
protocol：连接器使用的协议，支持HTTP和AJP。AJP（Apache Jserv Protocol）专用于tomcat与apache建立通信的.
redirectPort：指定服务器正在处理http请求时收到了一个SSL传输请求后重定向的端口号
maxThreads：接收最大请求的并发数
connectionTimeout  指定超时的时间数(以毫秒为单位)

5. Detailed explanation of host parameters

host:表示一个虚拟主机
name:指定主机名
appBase:应用程序基本目录，即存放应用程序的目录.一般为appBase="webapps"，相对于CATALINA_HOME而言的，也可以写绝对路径。
unpackWARs:如果为true，则tomcat会自动将WAR文件解压，否则不解压，直接从WAR文件中运行应用程序
autoDeploy:在tomcat启动时，是否自动部署

2. Use war package to deploy web site (jenkins)

Tomcat single-node configuration
There are two ways to go online code: The
first way is to directly put the program directory under the webapps directory The
second way is to use the development tool to package the program into a war package, and then upload it to the webapps directory

使用war包部署web站点**
[root@java-tomcat1 ~]# pwd
/root
下载jenkins的war包
[root@java-tomcat1 ~]# wget http://updates.jenkins-ci.org/download/war/2.129/jenkins.war
[root@java-tomcat1 ~]# ls
jenkins.war                
[root@java-tomcat1 ~]# cd /data/application/tomcat   #进入tomcat目录
[root@java-tomcat1 tomcat]# cp -r webapps/ /opt/    #将原来的发布网站目录备份
[root@java-tomcat1 tomcat]# cd webapps/
[root@java-tomcat1 webapps]# ls
docs  examples  host-manager  manager  ROOT
[root@java-tomcat1 webapps]# rm -rf *    #清空发布网站里面的内容
[root@java-tomcat1 webapps]# cp /root/jenkins.war .   #将war包拷贝到当前目录
[root@java-tomcat1 webapps]# ../bin/startup.sh   #启动
Using CATALINA_BASE:   /data/application/tomcat
Using CATALINA_HOME:   /data/application/tomcat
Using CATALINA_TMPDIR: /data/application/tomcat/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /data/application/tomcat/bin/bootstrap.jar:/data/application/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@java-tomcat1 webapps]# ls
jenkins  jenkins.war

二、手动解压:
[root@java-tomcat1 webapps]# ../bin/shutdown.sh   #关闭tomcat
[root@java-tomcat1 ~]# cd /data/application/tomcat/webapps/
[root@java-tomcat1 webapps]# rm -rf *    
[root@java-tomcat1 webapps]# mkdir ROOT      #创建一个ROOT目录存放war包
[root@java-tomcat1 webapps]# ls
ROOT
[root@java-tomcat1 webapps]# cd ROOT/
[root@java-tomcat1 ROOT]# cp /root/jenkins.war .
[root@java-tomcat1 ROOT]# unzip jenkins.war

3. Deploy an open source site (jspgou mall)

The first milestone: Install the configuration database

[root@java-tomcat1 ~]# wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
[root@java-tomcat1 ~]# rpm -ivh mysql80-community-release-el7-3.noarch.rpm
[root@java-tomcat1 ~]# cd /etc/yum.repos.d/
[root@java-tomcat1 yum.repos.d]# vim mysql-community.repo
注意enabled中0表示关闭，1表示开启

安装
yum clean all 
yum makecache
[root@java-tomcat1 yum.repos.d]# yum -y install mysql-server mysql
[root@java-tomcat1 yum.repos.d]# cd
[root@java-tomcat1 ~]# systemctl start mysqld
[root@java-tomcat1 ~]# systemctl enable mysqld
查找密码并修改密码
[root@java-tomcat1 ~]# grep pass /var/log/mysqld.log   #过滤查找密码
2019-07-05T15:57:15.294365Z 1 [Note] A temporary password is generated for root@localhost: %6yx817IeX-J
[root@java-tomcat1 ~]# mysqladmin -u root -p'%6yx817IeX-J' password 'QianFeng@123' #修改密码

Configuration database

[root@java-tomcat1 ~]# mysql -u root -p'QianFeng@123'

The second milestone: jspgou mall goes online

上传jspgou商城的代码
[root@java-tomcat1 ~]# unzip jspgouV6.1-ROOT.zip
[root@java-tomcat1 ~]# cp -r ROOT/ /data/application/tomcat/webapps/
[root@java-tomcat1 ~]# cd /data/application/tomcat/webapps/
[root@java-tomcat1 webapps]# ls
ROOT
[root@java-tomcat1 webapps]# vim ROOT/WEB-INF/config/jdbc.properties

Configure database connection----jdbc

将数据导入数据库:
[root@java-tomcat1 ~]# cd DB/
[root@java-tomcat1 DB]# ls
jspgou.sql
[root@java-tomcat1 DB]# mysql -uroot -p'QianFeng@123' -D jspgou < jspgou.sql
mysql: [Warning] Using a password on the command line interface can be insecure.

[root@java-tomcat1 DB]# systemctl restart mysqld
[root@java-tomcat1 DB]# mysql -uroot -p'QianFeng@123' -D jspgou < jspgou.sql
启动tomcat访问:
[root@java-tomcat1 ~]# /data/application/tomcat/bin/startup.sh
[root@java-tomcat1 ~]# netstat -lntp
