nginx的牛逼之处就不用多说了，反正一个字：牛逼！
先安装编译工具
yum -y install gcc gcc-c++ make
A. 依耐安装
nginx 依赖于 zlib pcre ssl 三个模块，
- zlib:nginx提供gzip模块，需要zlib库支持 ;
- openssl:nginx提供ssl功能 ;
- pcre:支持地址重写rewrite功能，支持nginx伪静态
有两种方式：
-
yum安装
yum -y install zlib-devel pcre-devel openssl-devel -
编译安装
cd /opt
- openssl编译
wget https://www.openssl.org/source/openssl-1.0.2q.tar.gz
./config --prefix=/usr/local/openssl
make && make install
/usr/local/openssl/bin/openssl version
- pcre编译（依耐8版本）
官网下载地址： https://ftp.pcre.org/pub/pcre/
wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz
./configure && make && make install
- zlib编译
wget http://zlib.net/zlib-1.2.11.tar.gz
./configure && make && make install
建议安装方式:
yum安装zlib和pcre
yum -y install zlib-devel pcre-devel
编译安转openssl
B. nginx安装
wget http://nginx.org/download/nginx-1.10.2.tar.gz
./configure --prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-openssl=/opt/openssl-1.0.2q
make && make install
注意：
1. --prefix 可以省略，默认安装在/usr/local/nginx
2. 这3个扩展的目录是他们的源代码目录，不是安装目录，这点很容易搞错。
--with-pcre=/opt/pcre-8.32 \
--with-zlib=/opt/zlib-1.2.7 \
--with-openssl=/opt/openssl-1.0.2q
启动 nginx
/usr/local/nginx/sbin/nginx
/usr/local/nginx/sbin/nginx -s reload
报错了（编译安装的pcre），error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory，按照下面方式解决
1.用whereis libpcre.so.1命令找到libpcre.so.1在哪里
2.用ln -s /usr/local/lib/libpcre.so.1 /lib64命令做个软连接就可以了
3.用sbin/nginx启动Nginx
4.用ps -aux | grep nginx查看状态
[root@localhost nginx]# whereis libpcre.so.1
[root@localhost nginx]# ln -s /usr/local/lib/libpcre.so.1 /lib64
[root@localhost nginx]# sbin/nginx
[root@localhost nginx]# ps -aux | grep nginx
- 查看端口
netstat -tnl|grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN

开启nginx的iptables限制
vim /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
然后，重启下 iptables。
service iptables restart
C. 开启自启动nginx
开机启动的配置文件是：/etc/rc.local
vim 末尾加入 /usr/local/nginx/sbin/nginx 即可
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/usr/local/bin/redis-server /etc/redis.conf
/usr/local/php/sbin/php-fpm
/usr/local/nginx/nginx
配置启动脚本
启动脚本 (见最后)
vim /etc/init.d/nginx
chmod -R 755 /etc/init.d/nginx
vim /etc/init.d/nginx
chkconfig nginx on 开机启动
chkconfig --list
#!/bin/bash
# nginx - this script starts and stops the nginx daemon
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
