Tomcat ( 单机多 Tomcat 并存 )

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

shell > tail /usr/local/tomcat1/logs/catalina.out # 查看日志，这里有 tomcat 的开启、关闭信息
