为什么要更改 Nginx 服务的默认用户:就像更改 ssh 的默认 22 端口一样,增加安全性,Nginx 服务的默认用户是 nobody ,我们更改为 nginx
1、添加 nginx 用户
useradd nginx -s /sbin/nologin -M
2、更改 Nginx 配置文件
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf worker_processes 1; user nginx nginx; # 指定Nginx服务的用户和用户组 events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server_tokens off; server { listen 80; server_name www.abc.com; location / { root html/www; index index.html index.htm; } } }
3、重新加载 Nginx
[root@localhost ~]# /usr/local/nginx/sbin/nginx -t [root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload
4、验证是否生效
[root@localhost ~]# ps aux | grep nginx root 8901 0.0 0.1 45036 1784 ? Ss 13:54 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 8909 0.0 0.1 45460 1828 ? S 13:59 0:00 nginx: worker process # Nginx进程的所属用户为nginx
