一、安装nginx所需环境

# yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel -y

二、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-1.17..tar.gz
# cd nginx-1.17.

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

三、加入systemctl管理服务

1、进入到 /usr/lib/systemd/system 目录下，编辑文件 nginx.service

# cd /usr/lib/systemd/system
# vi nginx.service

2、在nginx.service文件中加入以下代码

[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

参数说明：

注意：[Service]的启动、重启、停止命令全部要求使用绝对路径

[Unit]:服务的说明
Description:描述服务
After:描述服务类别
[Service]服务运行参数的设置
Type=forking是后台运行的形式
ExecStart为服务的具体运行命令
ExecReload为重启命令
ExecStop为停止命令
PrivateTmp=True表示给服务分配独立的临时空间
[Install]运行级别下服务安装的相关设置，可设置为多用户，即系统运行级别为3

3、设置开机启动

# systemctl enable nginx.service

4、取消开机自启动

# systemctl disable nginx.service

5、其他命令

启动nginx服务

# systemctl start nginx.service

查看服务当前状态

# systemctl status nginx

[root@localhost system]# systemctl status nginx

停止nginx服务

# systemctl stop nginx

重新启动服务

# systemctl restart nginx

查看所有已启动的服务

# systemctl list-units --type=service
