Centos下nginx的安装
ps： 源码包下载、编译安装统一制定安装在/usr/local/src/路径下。
操作命令推荐使用全路径，方便以后ps查看
一、编译安装
1.安装编辑工具及库文件
- zlib: gzip支持
- openssl: 443，https
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
2.安装前置
1).pcre安装（rewrite模块）
PCRE库支持正则表达式。如果我们在配置文件nginx.conf中使用了正则表达式，那么在编译Nginx时就必须把PCRE库编译进Nginx，因为Nginx的HTTP模块需要靠它来**解析正则表达式**。另外，pcre-devel是使用PCRE做二次开发时所需要的开发库，包括头文件等，这也是编译Nginx所必须使用的。
pcre官网下载地址：https://ftp.pcre.org/pub/pcre/
# 下载
cd /usr/local/src/
wget https://ftp.pcre.org/pub/pcre/pcre-8.35.tar.gz
tar zxvf pcre-8.35.tar.gz
# 编译安装
cd pcre-8.35/
./configure
make && make install
3.nginx安装
nginx 官网下载地址：https://nginx.org/download/
nginx 编译安装路径 /usr/local/nginx
# 下载
cd /usr/local/src/
wget https://nginx.org/download/nginx-1.9.9.tar.gz
tar xvf nginx-1.9.9.tar.gz
cd nginx-1.9.9
# 编译安装
./configure \
--prefix=/usr/local/nginx \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-pcre=/usr/local/src/pcre-8.35
make && make install
编译成功后会在/usr/local/nginx路径下生成相关文件,目录结构如下:
tree nginx
nginx
├── client_body_temp [error opening dir]
├── conf
│ ├── fastcgi.conf
│ ├── fastcgi.conf.default
│ ├── fastcgi_params
│ ├── fastcgi_params.default

│ └── nginx.pid
├── proxy_temp [error opening dir]
├── sbin
│ └── nginx
├── scgi_temp [error opening dir]
└── uwsgi_temp [error opening dir]
4.开放端口
防火墙开放80端口
# 查询防火墙已开放端口
firewall-cmd --list-port
# 设置开放80端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
# 重启防火墙，生效设置
firewall-cmd --reload
二、常用命令
1.nginx命令
# 启动-通过配置文件
./nginx -c conf/nginx.conf
# 启动命令-全路径，方便ps查看
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
# 停止
./nginx -s stop
# 重启
./nginx -s reload
