nginx服务的启动 停止和重启

nginx 命令

启动 nginx 命令

启动代码格式： nginx安装目录地址 -c nginx配置文件地址
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

停止

nginx的停止有三种方式：

正常停止

• 1.查看进程号
  ps -ef|grep nginx

    [root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
    root     24083     1  0 14:22 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
    nobody   24084 24083  0 14:22 ?        00:00:00 nginx: worker process
    root     24090 23962  0 14:22 pts/0    00:00:00 grep --color=auto nginx

• 2.杀掉进程
  kill -QUIT 进程号

[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     25427     1  0 17:32 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   25428 25427  0 17:32 ?        00:00:00 nginx: worker process
root     25430 25398  0 17:32 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]# kill -QUIT 25427
[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     25432 25398  0 17:32 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]# 

快速停止

• 1.查看进程号
  ps -ef|grep nginx

• 2.杀死进程
  kill -TERM 进程号 或 kill -INT 进程号

[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     25434     1  0 17:33 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   25435 25434  0 17:33 ?        00:00:00 nginx: worker process
root     25437 25398  0 17:33 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]# kill -TERM 25434
[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     25443 25398  0 17:34 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]# 

强制停止

kill -9 进程号

[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     24083     1  0 Jan15 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   24084 24083  0 Jan15 ?        00:00:00 nginx: worker process
root     25416 25398  0 17:26 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]#  kill -9 24083
[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
nobody   24084     1  0 Jan15 ?        00:00:00 nginx: worker process
root     25418 25398  0 17:28 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]#  kill -9 24084
[root@izbp17dek6gh6fp3fctexdz ~]# ps -ef|grep nginx
root     25420 25398  0 17:28 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz ~]# 

重启

1.验证 nginx 配置文件是否正确

• 方法一、进入 nginx 安装目录sbin 下，输入命令 ./nginx -t

[root@izbp17dek6gh6fp3fctexdz ~]# cd /usr/local/nginx/sbin
[root@izbp17dek6gh6fp3fctexdz sbin]# 
[root@izbp17dek6gh6fp3fctexdz sbin]# 
[root@izbp17dek6gh6fp3fctexdz sbin]# 
[root@izbp17dek6gh6fp3fctexdz sbin]# 
[root@izbp17dek6gh6fp3fctexdz sbin]# 
[root@izbp17dek6gh6fp3fctexdz sbin]# ll
total 3660
-rwxr-xr-x 1 root root 3746656 Nov 26 10:02 nginx
[root@izbp17dek6gh6fp3fctexdz sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@izbp17dek6gh6fp3fctexdz sbin]# 

看到显示 nginx.conf syntax is ok 和 nginx.conf test is successful

说明配置文件正确！

• 方法二：在启动命令-c前加-t
  /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

[root@izbp17dek6gh6fp3fctexdz sbin]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@izbp17dek6gh6fp3fctexdz sbin]# 

2、重启Nginx服务

• 方法一：进入nginx可执行目录sbin下，输入命令./nginx -s reload 即可

[root@izbp17dek6gh6fp3fctexdz sbin]# cd /usr/local/nginx/sbin
[root@izbp17dek6gh6fp3fctexdz sbin]# ls
nginx
[root@izbp17dek6gh6fp3fctexdz sbin]# ./nginx -s reload
[root@izbp17dek6gh6fp3fctexdz sbin]# ps -ef|grep nginx
root     25445     1  0 17:34 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   25465 25445  0 17:44 ?        00:00:00 nginx: worker process
root     25467 25398  0 17:44 pts/0   

• 方法二：查找当前nginx进程号，然后输入命令：kill -HUP 进程号 实现重启nginx服务

[root@izbp17dek6gh6fp3fctexdz sbin]# ps -ef|grep nginx
root     25445     1  0 17:34 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   25465 25445  0 17:44 ?        00:00:00 nginx: worker process
root     25473 25398  0 17:44 pts/0    00:00:00 grep --color=auto nginx
[root@izbp17dek6gh6fp3fctexdz sbin]# kill -HUP 25445
[root@izbp17dek6gh6fp3fctexdz sbin]# ps -ef|grep nginx
root     25445     1  0 17:34 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody   25474 25445  0 17:45 ?        00:00:00 nginx: worker process
root     25476 25398  0 17:45 pts/0    00:00:00 grep --color=auto nginx
