CentOS 下 Nginx 安装

1. 安装依赖包

yum update 
yum install -y gcc pcre pcre-devel openssl openssl-devel gd gd-devel

2.上传 nginx-1.18.0.tar.gz 至 /usr/local/nginx

   需安装 lrzsz 在/usr/local/nginx目录下使用 rz 命令

yum install -y lrzsz

3.解压 

tar -xzvf nginx-1.18.0.tar.gz

4.  进入解压后的目录 运行 ./configure

[root@VM-0-7-centos nginx-1.12.2]# ./configure 
checking for OS
......

  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

5. make & make install

7. 为nginx 建立systemd服务

 

服务文件模板 参考： https://www.nginx.com/resources/wiki/start/topics/examples/systemd/

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
ExecReload=/usr/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

根据实际状况修改  

PIDFile \ExecStartPer \ExecStart \ ExexReload 

保存到  /lib/systemd/system/nginx.service

PID 文件须要提早建立好。

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx-s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

8.  systemctl daemon-reload 从新加载

9. 其余命令

启动nginx服务

systemctl start nginx.service

设置开机自启动

systemctl enable nginx.service

中止开机自启动

systemctl disable nginx.service

查看服务当前状态

systemctl status nginx.service

从新启动服务

systemctl restart nginx.service

查看全部已启动的服务

systemctl list-units --type=service

10. 将nginx 添加进环境变量

10.一、编辑/etc/profile

vim /etc/profile

10.二、在最后一行添加配置，:wq保存

PATH=$PATH:/usr/local/nginx/sbin
export PATH

10.三、使配置当即生效

source /etc/profile

11. nginx 经常使用命令

11.1 启动、从新加载、关闭

[root@VM-0-7-centos sbin]# nginx
[root@VM-0-7-centos sbin]# nginx -s reload
[root@VM-0-7-centos sbin]# nginx -s  stop

11.2 查看版本

nginx -v

[root@VM-0-7-centos sbin]# nginx -v
nginx version: nginx/1.18.0

12. 指定配置文件启动

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
