如何測試 nginx 配置文件在 Bash 腳本中是否有效?

如何在 Bash 腳本中測試 Nginx 配置文件?目前我在 shell 中使用 -t :

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

但我想在腳本中做到這一點?

使用退出狀態。從 nginx 手冊頁:

成功時退出狀態為 0,如果命令失敗,則退出狀態為 1。

並來自http://www.tldp.org/LDP/abs/html/exit-status.html

美元?讀取最後執行的命令的退出狀態。

一個例子:

[root@d ~]# /usr/local/nginx/sbin/nginx -t;echo $?
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
0
[root@d ~]# echo whatever > /usr/local/nginx/nonsense.conf
[root@d ~]# /usr/local/nginx/sbin/nginx -t -c nonsense.conf;echo $?
nginx: [emerg] unexpected end of file, expecting ";" or "}" in /usr/local/nginx/nonsense.conf:2
nginx: configuration file /usr/local/nginx/nonsense.conf test failed
1

一個腳本範例:

#!/bin/bash
/usr/local/nginx/sbin/nginx -t 2>/dev/null > /dev/null
if [[ $? == 0 ]]; then
echo "success"
# do things on success
else
echo "fail"
# do whatever on fail
fi
