RedHat Enterprise Linux 6.4配置Xmanager 4
以管理员执行以下操作
1、vi /etc/inittab
id:5:initdefault: //设置系统运行级为5,如果本来就是5就无需修改
id:5:respawn:/usr/sbin/gdm //添加到最后一行
2、然后重启X11
init 3
init 5
3、vi /etc/gdm/custom.conf
# GDM configuration storage
[daemon]
[security]
[xdmcp]
Enable=1
[greeter]
[chooser]
[debug]
在相应位置添加红色行再 /wq保存。重启即可。
客户端(Windows端):(注意:有时Windows防火墙也会阻断Xmanager,提示时放开即可)
在客户端安装Xmanager 4 ,打开Xbrowser ,可在ADDRESS 栏输入IP 地址 如:192.168.10.212即可
如果防火墙打开了,使用以下命令打开177端口:
iptables -A INPUT -p udp –dport 177 -j ACCEPT
vi /etc/sysconfig/iptables
-A INPUT -m state –state NEW -m tcp -p tcp –dport 177 -j ACCEPT
-A INPUT -m state –state NEW -m udp -p udp –dport 177 -j ACCEPT
/etc/init.d/iptables restart
vi /etc/sysconfig/iptables
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT(允许80端口通过防火墙)
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT(允许3306端口通过防火墙)
特别提示:很多网友把这两条规则添加到防火墙配置的最后一行,导致防火墙启动失败,正确的应该是添加到默认的22端口这条规则的下面
添加好之后防火墙规则如下所示:
