详细说明：Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。 Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器，在BSD-like 协议下发行。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有:百度、京东、新浪、网易、腾讯、淘宝等。该文档详细讲述了nginx在企业线上环境的优化部署，更好的提工了安全性以及处理能力。实验环境: 主机 P地址软件包 192168200100(V|P) Nginx 192168.200101 nginx+keepalived Nginx 192.168.200.102 nginx+keepalived Tomcat 192.168.200103 jdkttomcat+ sLSaleSystem Tomcat 2 192168.200.104 jdk+tomcat+SLSaleSystem MYSQL 192.168.200.105 mysql 、 Nginx调度器构建源代码编译安装 ngInx rootnginx1I# useradd -M-S/sbin/nologin nginx [rootnginx"# yum-y install pcre-devel zlib-devel openssl-devel [rootnginx1"]* tar xf nginx-162. targz-C/usr/src/ frootnginx"]# cd /usr/src/nginx-162/ [rootnginx1 nginx-1.6. 2]# configure--prefix=/usr/local/ nginx--user=nginx--group=nginx with-file-aio--with-http_flv_module--with-httpstubstatus_module--with-http_sslmodule -with-httpgzipstatic_module--with-http_realipmodule&&make&&makeinstall [rootnginx ]# In-s/usr/local/nginx/sbin/*/usr/local/sbin/ 2、配置 nginx. conf配置文件 [rootnginx cd /usr/local/nginx/conf [rootnginx conf]# cp nginx conff bak) [rootnginx conf]# vim nginx. conf PI gInx ngIn worker_ processes 2;
