nginx负载均衡实现tomcat动态静态页面分离.
实验步骤
Web节点配置：（IP:192.168.139.128 IP:192.168.139.126）
[root@localhost soft]# tar zxvf jdk-8u11-linux-x64.tar.gz
#解压文件
[root@localhost soft]# mv jdk1.8.0_11/ /usr/local/
#将文件移动到/usr/local
[root@localhost soft]# cd /usr/local/
[root@localhost local]# ll
#查看文件所有者所属组
[root@localhost local]# chown root.root jdk1.8.0_11/
#更改所有者和所属组
[root@localhost local]# ll
[root@localhost local]# cd jdk1.8.0_11/
[root@localhost jdk1.8.0_11]# vi /etc/profile
[root@localhost jdk1.8.0_11]# source /etc/profile
#使/etc/profile的更改立即生效
[root@localhost jdk1.8.0_11]# cd ~/soft/
[root@localhost soft]# tar zxvf apache-tomcat-8.0.9.tar.gz
[root@localhost soft]# mv apache-tomcat-8.0.9 tomcat
#将文件改名为tomcat
[root@localhost soft]# mv tomcat/ /usr/local/
[root@localhost soft]# cd /usr/local/tomcat/bin/
[root@www bin]# ./startup.sh
#启动tomcat
负载均衡配置：
[root@google gohb]# cd /usr/local/nginx/conf/
[root@google conf]# vi nginx.conf
[root@google conf]# cd ..
[root@google nginx]# cd sbin/
[root@google sbin]# ./nginx -s stop
[root@google sbin]# ./nginx
小编的nginx.conf文件如下（含Linux网络配置之（十一）的配置）
