nginx安装配置-在centos7上

一、Nginx 简介

Nginx (engine x) 是一个高性能的HTTP和反向代理服务器,也是一个IMAP/POP3/SMTP服务器。Nginx是由伊戈尔·赛索耶夫为俄罗斯访问量第二的Rambler.ru站点(俄文:Рамблер)开发的,其将源代码以类BSD许可证的形式发布,因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。
Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器,并在一个BSD-like 协议下发行。其特点是占有内存少,并发能力强。

二、配置Nginx 源

Official Red Hat/CentOS packages

To add NGINX yum repository, create a file named /etc/yum.repos.d/nginx.repo and paste one of the configurations below:

CentOS:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

RHEL:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/rhel/$releasever/$basearch/
gpgcheck=0
enabled=1

Due to differences between how CentOS, RHEL, and Scientific Linux populate the $releasever variable, it is necessary to manually replace $releasever with either 5 (for 5.x) or 6 (for 6.x), depending upon your OS version.

三、centos7 安装 Nginx

1、利用 yum 进行安装

yum install nginx

2、利用命令行 进行编译安装 make install 待补充。。。

四、运行Nginx

#直接运行命令即可
nginx

五、Nginx使用帮助

# 运行帮助 命令即可
nginx -h
nginx version: nginx/1.12.2
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /etc/nginx/)
  -c filename   : set configuration file (default: /etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

直接输入 nginx 就可以启动 nginx 了或者 如下命令

#启动 nginx 服务
systemctl start nginx;
systemctl start nginx.service
#设置开机启动
systemctl enable nginx;
systemctl enable  nginx.service
#取消开启启动  
systemctl disable nginx
#查看状态
systemctl status nginx.service
#停止运行
systemctl stop nginx.service
