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：
几段生产环境的例子：
