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 proxylocation /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.comerror_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/;}
