Centos 7 编译安装nginx 并使用unit文件管理启动

一、准备工作：

1、安装必备工具：

[root@localhost ~]# yum -y install gcc gcc-c++ autoconf automake
[root@localhost ~]# yum -y install zlib zlib-devel openssl openssl-devel pcre-devel

2、安装之前，最好检查一下是否已经安装有nginx

[root@localhost ~]# find -name nginx

[root@localhost ~]# yum remove nginx    #如果安装了，先卸载

二、Nginx编译安装：

1、下载Nginx：http://nginx.org/en/download.html

[root@localhost ~]# cd /tmp
[root@localhost tmp]# wget http://nginx.org/download/nginx-1.14.0.tar.gz

2.解压编译

[root@localhost nginx-1.14.0]# useradd nginx
[root@localhost nginx-1.14.0]# passwd nginx

[root@localhost tmp]# tar -zxvf nginx-1.14.0.tar.gz
[root@localhost tmp]# cd nginx-1.14.0

[root@localhost nginx-1.14.0]# ./configure --prefix=/usr/local/nginx

3.安装

[root@localhost nginx-1.14.0]# make && make install

4.启动、重启、关闭

[root@localhost ～]/usr/local/nginx/sbin/nginx  //启动
[root@localhost ～]/usr/local/nginx/sbin -s reload //重启
[root@localhost ～]/usr/local/nginx/sbin -s stop //关闭

5.实现systemd管理nginx

[root@localhost nginx]# vim /usr/lib/systemd/system/nginx.service
[unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target

三、启动nginx服务

[root@localhost nginx]# systemctl daemon-reload
[root@localhost nginx]# systemctl start nginx
[root@localhost nginx]# systemctl status nginx
● nginx.service
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
