tomcat + nginx 负载均衡

虚拟机1 ： nginx

    1 systemctl stop firewalld
    2 setenforce 0
    3 yum -y install lrzsz
    4 rz
    5 ls
    6 tar -zxvf nginx-1.10.1.tar.gz -C /usr/src/
    7 cd /usr/src/nginx-1.10.1/
    8 yum -y install gcc gcc-c++ pcre-devel zlib-devel
    9 ./configure --prefix=/usr/local/nginx
   10 make && make install
   11 /usr/local/nginx/sbin/nginx
         测试 ip：80

虚拟机2： tomcat 1

1 systemctl stopfirewalld
    2 systemctl stop firewalld
    3 setenforce 0
    4 yum -y install java
    5 yum -y install lrzsz
    6 rz
    7 tar -zxvf apache-tomcat-7.0.68.tar.gz
    8 cp -r apache-tomcat-7.0.68 /opt/tomcat
    9 cd /opt/tomcat/bin/
   10 ./startup.sh
   11 cd /opt/tomcat/webapps/ROOT/
   12 ls
   14 mv index.jsp index.pl
   15 vim index.jsp          编写测试页面

测试 ip：8080

虚拟机3 ： tomcat2   1 systemctl stopfirewalld
    2 systemctl stop firewalld
    3 setenforce 0
    4 yum -y install java
    5 java -version
    6 yum -y install lrzsz
    7 rz
    8 tar -zxvf apache-tomcat-7.0.68.tar.gz
    9 cp -r apache-tomcat-7.0.68 /opt/tomcat
   10 cd /opt/tomcat/bin/
   11 ./startup.sh
   12 cd /opt/tomcat/webapps/ROOT/
   14 mv index.jsp index.pl
   15 vim index.jsp               编写测试页面

测试 ip:8080

负载均衡配置虚拟机1：nginx

15 vim /usr/local/nginx/conf/nginx.conf

       location / {                                         覆盖原有的   添加
              proxy_pass http://daxian;            下对应
         }

            upstream daxian {                           上对应
               server 192.168.238.129:8080;       分别对应已建好的tomcat1   加端口号
                server 192.168.238.130:8080;          tomcat2      加端口号
           }
}                  备注：容易报错，如果在最后添加一定要加一个括号

19 pkill nginx
20 /usr/local/nginx/sbin/nginx 重启nginx

测试 ip 不断刷新，就实现了负载均衡了
