Homephp教程php手册PHP和Shell实现检查SAMBA与NFS Server是否存在

这篇文章主要介绍了PHP和Shell实现检查SAMBA与NFS Server是否存在,本文分别给出了PHP检查脚本和Shell检查脚本,需要的朋友可以参考下

通常会通过 /etc/fstab 来处理挂载的设置,然后再使用 mount -a 来重新确认挂载,最好在排程的程序用到挂载目录时也执行一次 mount -a,,挂载目录在断线后是不会自动回复的,mount -a 的 Timeout 其实还蛮久的,尤其是 Server 不存在的时候,所以最好还是用对应的 client 先确认 server 是否存在。

而检查 NFS 的 client 可以用 showmount 来处理,在 Ubuntu 上的安装方式如下:

复制代码 代码如下:


sudo aptitude install nfs-common


而 SAMBA 的 client 则是用 smbclient,在 Ubuntu 上的安装方式如下:

复制代码 代码如下:


sudo aptitude install smbclient


检查 NFS Server 是否存在的流程
以 Shell 的方式检查

复制代码 代码如下:


# 先以 client 确认 server 是否存在   
/sbin/showmount 192.168.0.6 >/dev/null 2>&1   
if [ "j$?" != "j0" ]; then     
   echo "NFS Server is not exist"   
   exit 1   
fi   
   
# 重新确认挂载    
mount -a >/dev/null 2>&1   
if [ "j$?" != "j0" ]; then   
   echo "NFS Server mount failed"   
   exit 1;   
fi   


以 PHP 的方式检查

复制代码 代码如下:


/*先以 client 确认 server 是否存在*/    
$state = shell_exec('/sbin/showmount 192.168.0.6 >/dev/null 2>&1; echo $?');   
if(trim($state)!='0'){   
   echo "NFS Server is not exist";   
   exit;   
}   
   
/*重新确认挂载*/    
if(shell_exec('mount -a 2>&1')){   
   echo "NFS Server mount failed"   
   exit;   
}   

检查 SAMBA Server 是否存在的流程

以 Shell 的方式检查

复制代码 代码如下:


# 先以 client 确认 server 是否存在   
smbclient -NL //192.168.0.6 >/dev/null 2>&1   
if [ "j$?" != "j0" ]; then     
   echo "SAMBA Server is not exist"   
   exit 1   
fi   
   
# 重新确认挂载    
mount -a >/dev/null 2>&1   
if [ "j$?" != "j0" ]; then   
   echo "SAMBA Server mount failed"   
   exit 1;   
fi   


以 PHP 的方式检查

复制代码 代码如下:


/*先以 client 确认 server 是否存在*/    
$state = shell_exec('smbclient -NL //192.168.0.6 >/dev/null 2>&1; echo $?');   
if(trim($state)!='0'){   
   echo "SAMBA Server is not exist";   
   exit;   
}   
   
/*重新确认挂载*/    
if(shell_exec('mount -a 2>&1')){   
   echo "SAMBA Server mount failed"   
   exit;   
}
