CentOS Server 问题汇总

1. 关于VNC中出现的 Error: could not run xauth

If the SELinux configuration is set to enforcing then we need to make sure the home directories are set in the correct context:

$ egrep -e '^SELINUX=' /etc/selinux/config
$ SELINUX=enforcing

Taking a look at the SELinux settings for the home directories (use Z with the ls command):

$ ls -aslZ /home/
total 36
drwxr-xr-x. root    root    system_u:object_r:home_root_t:s0 .
drwxr-xr-x. root    root    system_u:object_r:root_t:s0      ..
drwx------. 55 unconfined_u:object_r:home_root_t:s0 jason users  4096 Jan 20 14:22 jason

The context for my home directory (jason) should be unconfined_u:object_r:user_home_dir_t:s0 and not unconfined_u:object_r:home_root_t:s0 as it is a home directory and not part of the root file system per se.

2. LDAP管理

login->beetle: x.x.45.210:636(SSL)
cn=admin,dc=vlsi5,dc=vlsi,dc=zju,dc=edu,dc=cn
pw->Gemini7!30
test connection成功的话fetch DNs

3. 新建用户后(adduser或用ldap新建)

在/home下

$ restorecon $USER -R
$ ls -Z

查看是否user_home_dir

4. 故障排除：

iptables -S 查看端口开的情况 system-config-firewall 设置端口，防火墙等

5. windows虚拟机

root登录diamond后，执行 virt-manager
