nginx部署遇上的问题

[emerg] mkdir() “/etc/nginx/client_body_temp” failed (13: Permission denied)

报错：nginx: [emerg] mkdir() "/etc/nginx/client_body_temp" failed (13: Permission denied)	#创建client_body_temp文件夹失败没有权限

[root@test02 etc]# systemctl status nginx.service	#查看nginx启动状态

问题原因：由于没有关闭selinux导致nginx启动不了

#解决方法：
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
#使用以上两个命令关闭selinux，再次启动nginx就OK 了
systemctl start nginx.service

这里是我出错的原因，大家可以尝试一下创建client_body_temp目录

mkdir /etc/nginx/client_body_temp	#创建这个目录
systemctl start nginx.service	#尝试启动nginx服务
