Centos下nginx的安装

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
│   ├── koi-utf
│   ├── koi-win
│   ├── mime.types
│   ├── mime.types.default
│   ├── nginx.conf
│   ├── nginx.conf.default
│   ├── scgi_params
│   ├── scgi_params.default
│   ├── uwsgi_params
│   ├── uwsgi_params.default
│   └── win-utf
├── fastcgi_temp [error opening dir]
├── html
│   ├── 50x.html
│   └── index.html
├── logs
│   ├── access.log
│   ├── error.log
│   └── 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

2.nginx 域名配置（include方式）
