做個總結
linux服務器上做負載均衡
自己準備的:linux服務器(45.78.20.168),jdk1.7,nginx,redis,tomcat7兩個,部署的項目;
1:jdk1.7安裝,兩個tomcat分別端口8080,8081;部署相同的項目;啟動;
http://45.78.20.168:8080/redis3.2/getRedis.action2:安裝nginx,添加負載的配置,安裝目錄下找
/etc/nginx/conf.d/default.conf文件(或/etc/nginx/nginx.conf);策略設置為默認輪詢;
upstream www.nimenhaihaoma.com {
server 45.78.20.168:8080;
server 45.78.20.168:8081;
}
server{
listen 80;
server_name www.nimenhaihaoma.com;
location / {
proxy_pass http://www.nimenhaihaoma.com;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
3:配置session共享,方式很多,這里用的redis的session共享(兼容jdk版本至少1.7):
tomcat的lib包加
commons-pool2-2.0.jar,jedis-2.5.2.jar,tomcat-redis-session-manager1.2.jar;
tomcat配置文件context.xml,在標簽<Context>內添加配置:
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" host="localhost" port="6379" database="0" maxInactiveInterval="60" />
4:項目里面區分session的代碼:
(1):放session的接口(執行一次);
(2):取session數據(不斷刷新),看tomcat打印信息;
5:效果,
