Linux安装JDK，Tomcat，Nginx，Redis教程

安装JDK并配置环境变量

1.下载JDK

2.解压

tar xzf jdk-7u79-linux-x64.tar.gz

3.配置环境变量（配置完成之后需要重启）

用文本编辑器打开/etc/profile
在profile文件末尾加入：
export JAVA_HOME=/usr/share/jdk1.7.0_79
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

安装tomcat

直接复制进去即可

安装nginx

安装完成之后访问此机器的80端口，能出来Welcome to nginx!说明安装成功

安装telnet服务端

关闭防火墙

有3种方式

1) 重启后生效
开启： chkconfig iptables on
关闭： chkconfig iptables off

2) 即时生效，重启后失效
开启： service iptables start
关闭： service iptables stop

需要说明的是对于Linux下的其它服务都可以用以上命令执行开启和关闭操作。

在开启了防火墙时，做如下设置，开启相关端口，
修改/etc/sysconfig/iptables 文件，添加以下内容：
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

Nginx配置

Redis配置

安装Redis

复制redis-2.8.18.tar.gz到linux某个目录下，解压

启动Redis

cd redis-2.8.18/src/

./redis-server

在tomcat中配置Redis

1.在tomcat的lib中引入3个依赖包

tomcat-redis-session-manager-1.2-tomcat-6.jar

tomcat-redis-session-manager-1.2-tomcat-7.jar

commons-pool-1.6.jar

jedis-2.1.0.jar

2.在tomcat的context.xml文件中配置Redis的配置信息

<Valve className="com.radiadesign.catalina.session.RedisSessionHandlerValve"/>
<Manager className="com.radiadesign.catalina.session.RedisSessionManager"
host="127.0.0.1"
port="6379"
database="0"
maxInactiveInterval="60"/>
