nginx 重启前进行一次验证
#!/bin/bash
set -x
nginxbin=`/usr/local/nginx/sbin/nginx -t`
if [[ ${nginxbin} == *successful* ]]; then
echo "nginx configure file ok"

else
echo "nginx configure file failed"
fi

根本不行啊

Nginx

nginxbin

configure

echo

@panzhc 谢谢，试了下可用。只是不太理解 /opt/meida/nginx/sbin/nginx -t >/dev/null 2>&1; 这句的含义。把错误和正确的都丢到丢弃怎么判断的

@panzhc
现在写好了不太理解。
if /usr/local/nginx/sbin/nginx -t >/dev/null 2>&1; then
echo "nginx configure file ok"

if /etc/init.d/nginx status >/dev/null 2>&1; then
echo "nginx running"
/etc/init.d/nginx reload
else
echo "nginx is stop"
/etc/init.d/nginx stop
/etc/init.d/nginx start
exit
fi

else
echo "nginx configure file failed"
exit
fi

>/dev/null 标准输出到 /dev/null 设备，该设备是『黑洞』
2>&1 将错误输出（ 2 ）定向到标准输出（ 1 ）
（：节点是不是搞错了？

@exuxu 上面这个脚本正常工作我测试过

程序退出到时候有个代码，可以通过 $? 取到，写成下面也一样
/opt/meida/nginx/sbin/nginx -t >/dev/null 2>&1
if [ $? -eq 0 ] then
echo "nginx configure file ok"
else
echo "nginx configure file failed"
fi
重定向只不过是不想看到多余的输出
