在nginx.conf中http标签内定义upstream
upstream name { #name自定义一个名字
server ip1:port weight=5;
server ip2:port weight=5
}
在server标签内的location/中
loation /{
proxy_pass http name； #使用upstream定义的name
proxy_set_header X-Real_IP $remote_addr;
client_max_body_size 100m;
}
对特殊目录限制权限
location ~ ^/(WEB-INF)/ {
denny all;
}
tomcat设置
使用memcached-session-manager这个开源项目（http://code.google.com/p/memcached-session-manager，下面简称msm）配置Tomcat和memcached实现session共享。
首先将下面的包下载到Tomcat的lib目录下，这些包都是msm所依赖的包。
[[email protected] ~]# cd /usr/local/tomcat/lib/ [[email protected] lib]# wget http://memcached-session-manager.googlecode.com/files/memcached-session-manager-1.3.0.jar [[email protected] lib]# wget http://memcached-session-manager.googlecode.com/files/msm-javolution-serializer-jodatime-1.3.0.jar [[email protected] lib]# wget http://memcached-session-manager.googlecode.com/files/msm-javolution-serializer-cglib-1.3.0.jar [[email protected] lib]# wget http://spymemcached.googlecode.com/files/memcached-2.4.2.jar [[email protected] lib]# wget http://memcached-session-manager.googlecode.com/files/javolution-5.4.3.1.jar
修改server.xml
<Context docBase="/var/www/html" path="" reloadable="true"> <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:localhost:11211" requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$" sessionBackupAsync="false" sessionBackupTimeout="100" transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory" copyCollectionsForSerialization="false" /> </Context>
这里的memcachedNodes是填写memcached节点,多个节点时可以以空隔分开，如:
n1:localhost:11211 n2:localhost:11212 /localhost改为安装memcached的服务器的IP
sessionBackupTimeout的单位为分钟
/var/www/html改为Tomcat服务器web根目录的路径
修改后重启TOMCAT和nginx服务
