修改后强制保存

vim /etc/sudoers

创建nginx用户

useradd nginx -u 2019

id nginx
uid=2019(nginx) gid=2019(nginx) groups=2019(nginx)

将nginx改为默认用户

vim /apps/nginx/conf/nginx.conf

user  nginx;   <--

/apps/nginx/sbin/nginx -s reload

ps -ef|grep nginx
root      58430      1  0 01:32 ?        00:00:00 nginx: master process /apps/nginx/sbin/nginx
