Nginx

[suhao]

Nginx是一款由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器。

在高连接并发的情况下，Nginx是Apache服务器不错的替代品。

Nginx安装

安装编译工具及库文件

yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel

安装PCRE

PCRE作用是让Nginx支持Rewrite功能

# 获取压缩包
wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

# 解压安装包
tar zxvf pcre-8.35.tar.gz

# 进入安装包目录
cd pcre-8.35

# 编译安装
./configure
make && make install

# 查看pcre版本
pcre-config --version

安装Nginx

# 下载Nginx
wget http://nginx.org/download/nginx-1.6.2.tar.gz

# 解压
tar zxvf nginx-1.6.2.tar.gz

# 进入安装包目录
cd nginx-1.6.2

# 编译安装
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
make
make install

# 查看nginx版本
/usr/local/webserver/nginx/sbin/nginx -v

Nginx配置

创建Nginx运行使用的用户www

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www

配置nginx.conf

将/usr/local/webserver/nginx/conf/nginx.conf 替换为如下内容：

# 打开并编辑nginx.conf
cat /usr/local/webserver/nginx/conf/nginx.conf


user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和级别
pid /usr/local/webserver/nginx/nginx.pid;

worker_rlimit_nofile 65535;
events

  use epoll;
  worker_connections 65535;
