部署环境
| 主机 | 软件版本 |
| 192.168.88.1 | nginx-1.12.2+redis-3.2.11 |
| 192.168.88.2 | apache-tomcat-7.0.79 + jdk1.8 |
| 192.168.88.3 | apache-tomcat-7.0.79 + jdk1.8 |
所需tomcat jar包，下载
- commons-pool-1.5.4.jar
- commons-pool2-2.4.1.jar
- jedis-2.6.2.jar
- tomcat-juli-adapters.jar
- tomcat-juli.jar
- tomcat-redis-session-manager1.2.jar
Tomcat配置
- 把tomcat jar包复制到$TOMCAT_BASE 下的lib目录
- 修改tomcat的配置文件conf/comtext.xml
#单点redis配置（我已经配置成功）
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="192.168.88.1"
port="6379"
database="0"
maxInactiveInterval="60"/>
</Context>
#基于redis集群配置（我还没测试）
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
maxInactiveInterval="60"
sentinelMaster="mymaster"
sentinels="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381"/>
</Context>
3、添加一个tomcat测试页index.jsp
# cat /opt/tomcat/webapps/ROOT/index.jsp <html> <head> <title>nginx tomcat session test</title> <meta name="Generator" content="EditPlus"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> </head> <h1>tomcat88.2</h1> #这里192.168.88.3机器改为tomcat88.3 session: <%=session.getId()%> </html>
4、启动tomcat
nginx配置
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream tomcat {
server 192.168.88.2:8080 weight=1;
server 192.168.88.3:8080 weight=1;
}
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://tomcat;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
