概述：Nginx是一个轻便的支持高并发的HTTP和反向代理服务器，运用很广。这里记录下Linux下Nginx的安装步骤，这里以centos系统为例，安装Nginx1.7.9，安装目录为/usr/local。

一、安装Nginx依赖环境

1、安装gcc-c++

# yum install -y gcc-c++

2、下载pcre

#cd /usr/local

#wget http://sourceforge.net/projects/pcre/files/pcre/8.35/pcre-8.35.tar.gz

#tar zxvf pcre-8.35.tar.gz

3、安装zlib

# cd /usr/local

# wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.8.tar.gz

# tar zxvf zlib-1.2.8.tar.gz

# cd zlib-1.2.8

# ./configure --prefix=/usr/local/zlib

# make && make install

4、安装openl

# cd /usr/local

# wget http://www.openssl.org/source/openssl-1.0.1h.tar.gz

# tar zxfv openssl-1.0.1h.tar.gz

# cd openssl-1.0.1h

# ./config --prefix=/usr/local/openssl

# make && make install

二、安装Nginx

# cd /usr/local

# wget http://nginx.org/download/nginx-1.7.9.tar.gz

# tar zxvf nginx-1.7.9.tar.gz

# cd nginx-1.7.9

#./configure --with-pcre=/usr/local/pcre-8.35 --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-zlib=/usr/local/zlib-1.2.8 --with-openssl=/usr/local/openssl-1.0.1h

#make && make install

解决nginx启动时报错:

[error]open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file ordirectory)

#/usr/local/nginx/sbin/nginx -c/usr/local/nginx/conf/nginx.conf
