1.copy 虚拟机后IP、联网问题

 

   当把vmwhare中的虚拟机copy出一台后是连接不上网的，因为IP/MAC地址都是冲突的，所以需要做设置。

   

  现象：当把ip地址修改后，重启网络（service network restart） 会报错：

   device eth0 does not seem to be present, delaying initialization

 

   这是因为/etc/sysconfig/network-script/ifcfg-eth0里面保存了之前的MAC 。

 

   解决：

 

   1.删除/etc/udev/rules.d/70-persistent-net.rules文件，重启

   2.打开/etc/udev/rules.d/70-persistent-net.rules文件，复制里面的MAC地址

   3.修改/etc/sysconfig/network-script/ifcfg-eth0文件的HWADDR，粘贴MAC地址

    4.重启网络：service network restart

 

 2.WIKI启动后，数据库链接不上

 

通过php的mysql_connect('localhost','usr','pass')连接本地数据库成功
但是，mysql_connect('127.0.0.1:3306','usr','pass')出现
can't connect to MySQL server using '' (13)的错误
原因：
#getsebool -a | grep httpd
[neo@neo phpMyTest]$ getsebool -a | grep httpd

allow_httpd_mod_auth_ntlm_winbind --> off

发现 httpd_can_network_connect --> off
解决方案：

#setsebool httpd_can_network_connect 1
