nginx实现tomcat的负载均衡及企业内部应用的代理

192.168.3.87 mysql+redis+tomcat

192.168.3.112 nginx:6688

192.168.3.86 nginx+h5

环境准备

a.安装包

open jdk 1.8

tomcat 8.0

nginx 1.1.13.tar.gz

mysql5.5.48.tar.gz

b.解析域名admin.chinasoft.com和ops.chinasoft.com到nginx负载均衡服务器

①后端3.87和3.112jdk的部署

yum install -y java-1.8.0-openjdk

yum install -y redis

验证是否安装成功

java -version

openjdk version "1.8.0_91"

OpenJDK Runtime Environment (build 1.8.0_91-b14)

OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode

②tomcat的部署

tar -zxvf apache-tomcat-8.0.36.tar.gz

mv apache-tomcat-8.0.36 /usr/local/tomcat

将tomcat的命令加入环境变量中

# vim /etc/profile.d/tomcat.sh

export CATALINA_HOME=/usr/local/tomcat

export PATH=$CATALINA_HOME/bin:$PATH

source /etc/profile.d/tomcat.sh

修改http的web端口为8888

vim /usr/local/tomcat/conf/server.xml

<Connector port="8888" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

启动服务并验证是否正常启动

startup.sh

ss -tunlp|grep 8888

③将war包放入webapps目录下，重新启动tomcat，验证是否成功，错误日志可以查看catalina.out文件

将域名解析指向nginx负载均衡器：192.168.8.86 admin.chinasoft.com

配置nginx负载均衡器

将具体的定义防止到/etc/nginx/conf文件目下

在nginx.conf中定义目录包含：

include /etc/nginx/conf/*.conf;

在conf目录下分别定义后端服务器，nginx中h5和zabbix等内部管理系统的定义

cat h5.conf

server {

access_log /data/logs/h5_acc.log; #访问日志

error_log /data/logs/h5_error.log info; #错误日志

server_name localhost; #因为是放置在本机，所以直接用Localhost

root /web/h5; #自定义存放web文件目录

}

cat flow_admin.conf

# 定义后端负载均衡的两台机器

upstream flows {

server 192.168.3.87:8888 weight=1;

server 192.168.3.112:6688 weight=1;

}

server {

server_name admin.chinasoft.com; #定义servername即指向nginx的域名

access_log /data/logs/flowadm_acc.log;

error_log /data/logs/flowadm_error.log info;

location / {

proxy_set_header Host $host;

proxy_set_header X-Real-Ip $remote_addr;

proxy_set_header X-Forwarded-For $remote_addr;

proxy_pass http://flows/;

}

}

负载均衡效果：

cat ops.conf

# 定义zabbix等内部服务

server {

server_name ops.chinasoft.com;

location /zabbix/ {

proxy_set_header Host $host;

proxy_set_header X-Real-Ip $remote_addr;

proxy_set_header X-Forwarded-For $remote_addr;

proxy_pass http://192.168.3.108/zabbix/;

}

}

几段生产环境的例子：

ops.conf

server{

      server_name ss.chinasoft.com;

      index index.html index.htm index.php;

#zabbix server access by nginx proxy

     location /zabbix/ {

             proxy_pass http://u04zbx01.yaya.corp/zabbix/;

      }

     location /ldap/ {

             proxy_pass http://u04dns01.yaya.corp/ldap/;

}

}

flow.conf

    server {

    server_name   flowadm.chinasoft.com;

    access_log  /data/logs/flowadm_access.log;

    error_log  /data/logs/flowadm_error.log  info;

    location / {

            proxy_set_header Host $host;

            proxy_set_header X-Real-Ip $remote_addr;

            proxy_set_header X-Forwarded-For $remote_addr;

            #proxy_pass  http://flows_admin;

            proxy_pass  http://u04flow01.yaya.corp:8888/;

    }

}

h5.conf

upstream flows {

    server u04flow01.yaya.corp:8080;

    server u04flow02.yaya.corp:8080;

}

server {

    server_name   flow.chinasoft.com;

    error_log  /data/logs/flow_h5.log  info;

    access_log /data/logs/flow_h5.log;

    location /h5/flow/{

        alias  /data/h5/flow/;

        index  index.html;

    }

    location /sdkApi/{

            proxy_set_header Host $host;

            proxy_set_header X-Real-Ip $remote_addr;

            proxy_set_header X-Forwarded-For $remote_addr;

            #proxy_pass  http://u04flow01.yaya.corp:8080/;

            proxy_pass  http://flows;

    }

    #error_page  404              /404.html;

}

web.conf

server {

    server_name   1.1.1.1;

    server_name   www.baidu.com www.aaa.com

    error_log  /data/logs/web-acccess.log  info;

    access_log /data/logs/web-error.log;

    location /{

      alias /home/hailitao/;   #这里为代码存放路径

      index  views/index/index.html;

    }

    location /api/{

                proxy_set_header Host $host;

                proxy_set_header X-Real-Ip $remote_addr;

                proxy_set_header X-Forwarded-For $remote_addr;

                proxy_pass  http://192.168.3.85:9783/;   #这里为服务端所部署的地址

    }

}

share.conf

upstream bills {

    server u04tv01.chinasoft.com:6643;

    server u04tv02.chinasoft.com:6643;

}

server {

    server_name  fx.chinasoft.com;

    error_log  /data/logs/share_error.log  info;

    access_log /data/logs/share_access.log;

    location /{

      alias /data/haili_share/;

      index room.html;

    }

    location /hailishare/{

           # proxy_set_header Host $host;

           # proxy_set_header X-Real-Ip $remote_addr;

           # proxy_set_header X-Forwarded-For $remote_addr;

            proxy_pass  http://bills/;

    }
