esac解決思路
開始以為是文件權限的問題。創(chuàng)建nginx用戶，并切換到nginx用戶啟動服務。
創(chuàng)建nginx nginx 組和用戶
passwd nginx #創(chuàng)建密碼登陸
并將ngixn 的所屬關系都使用chown更改。
chown nginx:nginx /usr/local/nginx -R #更改所屬關系
groupadd nginx
useradd -g nginx nginx
passwd nginx
su nginx #切換nginx用戶
/etc/init.d/nginx start #執(zhí)行啟動Nginx命令
#輸出

Authentication is required to manage system services or units.

Password:
#發(fā)現(xiàn)還是要輸入密碼...
#應該是解決思路不對，啟動關聯(lián)到了centos用戶，nginx用戶嘗試使用sudo命令啟動
sudo /etc/init.d/nginx start
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
[sudo] password for nginx:
nginx is not in the sudoers file. This incident will be reported.
#需要把nginx用戶加入sudoers 文件中,好麻煩...
#大致清楚了，就算root運行這個命令也需要root就切換到root嘗試了下。
exit
#root下sudo 運行成功

應該修改/etc/selinux/config
SELINUX=disabled
以后嘗試一下。
在生產(chǎn)環(huán)境 單獨創(chuàng)建出來個用戶運行nginx 比直接用root運行安全。還是使用nginx用戶來運行。
