Tomcat ( 单机多 Tomcat 并存 )
Tomcat ( 单机多 Tomcat 并存 )
简介：
Tomcat 扩展（ 一台服务器运行多个 tomcat ）
一、安装 JDK 、Tomcat
shell > rpm -ivh jdk-8u25-linux-x64.rpm # 安装 jdk ，jdk 版本最好与 tomcat 一致
shell > tar zxf apache-tomcat-8.0.14.tar.gz -C /usr/local/
shell > cd ..
shell > cp -r apache-tomcat-8.0.14 tomcat1 # 复制三份 tomcat 其中 tomcat1 保持不变
shell > cp -r apache-tomcat-8.0.14 tomcat2
shell > cp -r apache-tomcat-8.0.14 tomcat3
二、配置多 Tomcat
shell > vim tomcat2/conf/server.xml # 修改 tomcat2
22 <Server port="8006" shutdown="SHUTDOWN"> # 原端口为 8005 修改为 8006
69 <Connector port="8081" protocol="HTTP/1.1" # 原端口为 8080 修改为 8081
91 <Connector port="8019" protocol="AJP/1.3" redirectPort="8443" /> # 原端口为 8009 修改为 8019
shell > vim tomcat3/conf/server.xml # 修改 tomcat3
22 <Server port="8007" shutdown="SHUTDOWN"> # 原端口为 8005 修改为 8007
69 <Connector port="8082" protocol="HTTP/1.1" # 原端口为 8080 修改为 8082
91 <Connector port="8029" protocol="AJP/1.3" redirectPort="8443" /> # 原端口为 8009 修改为 8029
三、测试
shell > echo "welcome to tomcat1" > /usr/local/tomcat1/webapps/ROOT/index.html # 创建首面文件
shell > echo "welcome to tomcat2" > /usr/local/tomcat2/webapps/ROOT/index.html
shell > echo "welcome to tomcat3" > /usr/local/tomcat3/webapps/ROOT/index.html
shell > /usr/local/tomcat1/bin/startup.sh # 启动 tomcat1

## 可以启动、关闭任意 tomcat ，没有顺序之分。唯一注意的一点，就是启动有一个过程，需要稍微等等，不要急。
只需修改端口即可，无需按照网上所说，要设置变量、更改 catalina.sh 等文件（如有不对的地方，还请各位指正）
