九、配置Tomcat集群

配置Tomcat集群所需服务器三台：192.168.1.5（调度服务器）、192.168.1.10（WEB1），192.168.1.20(WEB2)

1.调度服务器设置

[root@proxy ~]# vim  /usr/local/nginx/conf/nginx.conf            

http{

    upstream toms {

        server 192.168.2.100:8080;

        server 192.168.2.200:8080;

    }

    server  {

        listen 80;

        server_name localhost;

        location / {

            proxy_pass  http://toms;

        }

    }

}  

2.web服务器设置（web{1，2}服务器设置相同）

[root@ web1 ~]# yum -y install java-1.8.0-openjdk   #安装jdk

[root@web1 ~]# yum -y install java-1.8.0-openjdk-headless

[root@web1 ~]# tar xf apache-tomcat-8.0.30.tar.gz

[root@web1 ~]# mv apache-tomcat-8.0.30 /usr/local/tomcat

[root@web1 ~]# ln -s /usr/local/tomcat/bin/startup.sh /sbin/

[root@web1 ~]# ln -s /usr/local//tomcat/bin/shutdown.sh /sbin/

[root@web1 ~]# startup.sh   #启动Tomcat

[root@web1 ~]# ls /usr/local/tomcat

bin/                                            //主程序目录

lib/                                            //库文件目录

logs/                                          //日志目录  

temp/                                         //临时目录

work/                                        //自动编译目录jsp代码转换servlet

conf/                                        //配置文件目录

webapps/                                        //页面目录

[root@web1 ~]# firewall-cmd --set-default-zone=trusted

[root@web1 ~]# setenforce 0
