192.168.3.87 ?mysql+redis+tomcat

192.168.3.112 nginx:6688
192.168.3.86 ?nginx+h5

環境準備

a.安裝包?
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負載均衡服務器

①后端3.87和3.112jdk的部署
yum install -y java-1.8.0-openjdk
yum install -y redis


驗證是否安裝成功


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


將tomcat的命令加入環境變量中
# 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端口為8888
vim /usr/local/tomcat/conf/server.xml?


?<Connector port="8888" protocol="HTTP/1.1"
? ? ? ? ? ? ? ?connectionTimeout="20000"
? ? ? ? ? ? ? ?redirectPort="8443" />


啟動服務并驗證是否正常啟動
startup.sh
ss -tunlp|grep 8888


③將war包放入webapps目錄下，重新啟動tomcat，驗證是否成功，錯誤日志可以查看catalina.out文件


將域名解析指向nginx負載均衡器：192.168.8.86 admin.chinasoft.com


配置nginx負載均衡器


將具體的定義防止到/etc/nginx/conf文件目下
在nginx.conf中定義目錄包含：


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


在conf目錄下分別定義后端服務器，nginx中h5和zabbix等內部管理系統的定義


cat h5.conf


server {
? ? access_log /data/logs/h5_acc.log; ? #訪問日志
? ? error_log /data/logs/h5_error.log info; #錯誤日志
? ? server_name localhost; #因為是放置在本機，所以直接用Localhost
? ? root /web/h5; #自定義存放web文件目錄
}


cat flow_admin.conf?


# 定義后端負載均衡的兩臺機器
upstream flows {
? ? server 192.168.3.87:8888 weight=1;
? ? server 192.168.3.112:6688 weight=1;
}
server {
? ? server_name ? admin.chinasoft.com; ? #定義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/;
? ? }

}

負載均衡效果：

cat ops.conf


# 定義zabbix等內部服務
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/;
? ? }

}

幾段生產環境的例子：

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/; #這里為代碼存放路徑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/; #這里為服務端所部署的地址} }

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/;} }
