Nginx ("engine x") 是一个高性能的 HTTP 和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器 。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的Rambler.ru 站点开发的,它已经在该站点运行超过四年多了。Igor 将源代码以类BSD许可证的形式发布。自Nginx 发布四年来,Nginx 已经因为它的稳定性、丰富的功能集、 示例配置文件和低系统资源的消耗而闻名了。目前国内各大门户网站已经部署了Nginx,如新浪、网易、腾讯等;国内几个重要的视频分享网站也部署了Nginx,如六房间、酷6等。 新近发现Nginx 技术在国内日趋火热,越来越多的网站开始部署Nginx。

将TOMCAT安装在/export/servers/tomcat_2
设置环境变量
#vi /etc/profile
export TOMCAT_2_HOME=/export/servers/tomcat_2
export CATALINA_2_HOME=/export/servers/tomcat_2
export CATALINA_2_BASE=/export/servers/tomcat_2
在PATH后面添加:$CATALINA_2_HOME/lib
保存退出
:wq
使环境变量生效
#source /etc/profile
修改TOMCAT配置文件/export/servers/tomcat_2/conf/server.xml
将以下内容
<Server port="8005" shutdown="SHUTDOWN">...
<Connector port="8080" protocol="HTTP/1.1" ...
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

在exec上添加以下内容
export JAVA_HOME=/usr/java/jdk1.7.0
export CLASSPATH=$JAVA_HOME/lib
export PATH=$JAVA_HOME/bin
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
修改TOMCAT配置启动文件/export/servers/tomcat_2/bin/shutdown.sh

启动TOMCAT
/export/servers/tomcat_2/bin/startup.sh
关闭TOMCAT
/export/servers/tomcat_2/bin/shutdown.sh
检查安装nginx的依赖性,nginx的模块需要第三方的支持,检查是否安装下列库:
[root@localhost bin]# yum install zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc
添加用户和组
[root@localhost bin]# groupadd nginx
[root@localhost bin]# useradd -g nginx nginx
安装nginx
[root@localhost servers]#tar -zxvf nginx-1.7.7.tar.gz
[root@localhost servers]#mv nginx-1.7.7 ngnix
[root@localhost servers]#cd ngnix
[root@localhost ngnix]#./configure --user=nginx --group=nginx --prefix=/export/servers/nginx
[root@localhost ngnix]#make
[root@localhost ngnix]#make install
