Tomcat笔记之多实例

规划端口定义信息

tomcat-01  8081 8006 8010
 tomcat-02  8082 8007 8011

部署多实例目录

[root@tomcat tools]# tar xf apache-tomcat-8.0.27.tar.gz 
 [root@tomcat tools]# mv apache-tomcat-8.0.27 tomcat-01
 [root@tomcat tools]# tar xf apache-tomcat-8.0.27.tar.gz 
 [root@tomcat tools]# mv apache-tomcat-8.0.27 tomcat-02

 [root@tomcat tools]# ll
 总用量 185908
 -rw-r--r--. 1 root root   9128610 10月 25 15:33 apache-tomcat-8.0.27.tar.gz
 -rw-r--r--. 1 root root 181238643 10月 25 15:27 jdk-8u60-linux-x64.tar.gz
 drwxr-xr-x. 9 root root       160 10月 26 09:25 tomcat-01
 drwxr-xr-x. 9 root root       160 10月 26 09:25 tomcat-02

修改端口号

[root@tomcat tools]# sed -i 's#8080#8081#g;s#8005#8006#g;s#8009#8010#g' tomcat-01/conf/server.xml

 [root@tomcat tools]# sed -i 's#8080#8082#g;s#8005#8007#g;s#8009#8011#g' tomcat-02/conf/server.xml

重新启动

[root@tomcat tools]# /application/tomcat-01/bin/startup.sh 
 Using CATALINA_BASE:   /application/tomcat-01
 Using CATALINA_HOME:   /application/tomcat-01
 Using CATALINA_TMPDIR: /application/tomcat-01/temp
 Using JRE_HOME:        /application/jdk
 Using CLASSPATH:       /application/tomcat-01/bin/bootstrap.jar:/application/tomcat-01/bin/tomcat-juli.jar
 Tomcat started.
 [root@tomcat tools]# /application/tomcat-02/bin/startup.sh 
 Using CATALINA_BASE:   /application/tomcat-02
 Using CATALINA_HOME:   /application/tomcat-02
 Using CATALINA_TMPDIR: /application/tomcat-02/temp
 Using JRE_HOME:        /application/jdk
 Using CLASSPATH:       /application/tomcat-02/bin/bootstrap.jar:/application/tomcat-02/bin/tomcat-juli.jar
 Tomcat started.

确定启动，查看端口

[root@tomcat tools]# ss -lntup|grep java
 tcp    LISTEN     0      1      ::ffff:127.0.0.1:8005                 :::*                   users:(("java",pid=4067,fd=67))
 tcp    LISTEN     0      1      ::ffff:127.0.0.1:8006                 :::*                   users:(("java",pid=4248,fd=69))
 tcp    LISTEN     0      1      ::ffff:127.0.0.1:8007                 :::*                   users:(("java",pid=4277,fd=69))
 tcp    LISTEN     0      100      :::8009                 :::*                   users:(("java",pid=4067,fd=51))
 tcp    LISTEN     0      100      :::8010                 :::*                   users:(("java",pid=4248,fd=51))
 tcp    LISTEN     0      100      :::8011                 :::*                   users:(("java",pid=4277,fd=51))
 tcp    LISTEN     0      100      :::8080                 :::*                   users:(("java",pid=4067,fd=46))
 tcp    LISTEN     0      100      :::8081                 :::*                   users:(("java",pid=4248,fd=46))
 tcp    LISTEN     0      100      :::8082                 :::*                   users:(("java",pid=4277,fd=46))

测试页面

[root@tomcat tools]# curl 127.0.0.1:8081
 jinc tomcat-01
 [root@tomcat tools]# curl 127.0.0.1:8082
 jinc tomcat-02

添加负载均衡

到之前负载均衡主机lb01，修改配置文件，以及修改windows主机hosts解析为负载均衡ip

配置文件代码

[root@lb01 ~]# cat /application/nginx/conf/nginx.conf
 http {
     upstream jinc {
  server 172.16.1.81:8081;
         server 172.16.1.81:8082;
 }
     include       mime.types;
     default_type  application/octet-stream;
     sendfile        on;
     keepalive_timeout  65;
     server   {
  listen      10.0.0.3:80;
  server_name  localhost;
     location ~* / {
  proxy_pass http://jinc;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $remote_addr;
  }
