Nginx安装及配置文件说明

 1、安装nginx所需环境　　

① gcc 安装

# yum install gcc-c++

② PCRE pcre-devel 安装

# yum install -y pcre pcre-devel

③ zlib 安装

# yum install -y zlib zlib-devel

④ OpenSSL 安装

# yum install -y openssl openssl-devel

2、安装Nginx

① 下载nginx

# wget -c https://nginx.org/download/nginx-1.12.1.tar.gz

② 解压

# tar -zxvf nginx-1.12.1.tar.gz
# cd nginx-1.12.1

③ 使用默认配置

# ./configure

④ 编译、安装

# make
# make install

⑤ 启动nginx

# cd /usr/local/nginx/sbin/
# ./nginx 

其它命令
# ./nginx -s stop
# ./nginx -s quit
# ./nginx -s reload

# 重启nginx
# /usr/local/nginx/sbin/nginx -s reload

⑥ 设置开机启动

# vim /etc/rc.local

添加一行：
/usr/local/nginx/sbin/nginx

# 设置执行权限
# chmod 755 rc.local

⑦ 查看nginx的版本及模块

/usr/local/nginx/sbin/nginx -V

 ⑧ 防火墙中打开Nginx端口（默认的 80） 

 firewall-cmd --zone=public --add-port=80/tcp --permanent  //--permanent永久生效,没有此参数防火墙重启便失效
