vmware 安装linux可能遇到的问题.docx

1.安装RHEL 64位系统遇到的问题系统在“Starting udev”处过不去，解决方法：(1)把虚拟机的电源关闭 (2)然后编辑配置,改为单个vCPU (3)启动系统 (4)编辑/etc/grub.conf在kernel一行最后加上clocksource=acpi_pm 2. Xmanager3.0连接配置RedHat Enterprise Linux 5Xmanager3.0连接配置RedHat Enterprise Linux 5环境介绍服务器：RedHat Enterprise Linux 5.0客户端：xmanager3.0英文版服务器相关配置文件介绍1./usr/share/gdm/defaults.conf-GNOME管理默认的配置文件2./etc/inittab-init进程的主配置文件3./etc/gdm/custom.conf-GNOME的自定义配置文件步骤如下：1.改变defaults.conf文件权限,默认是只读chmod 700 /usr/share/gdm/defaults.conf2.做如下配置-编辑/usr/share/gdm/defaults.conf将以下内容添加到defaults.conf后面：Enable=trueDisplaysPerHost=10Port=177AllowRoot=trueAllowRemoteroot=trueAllowRemoteAutoLogin=false3.做如下配置-编辑/etc/gdm/custom.confxdmcpEnable=14.做如下配置-编辑/etc/inittab，注意：不要修改原来设置,在最后新增一行如下记录x:5:respawn:/usr/sbin/gdm5.配置防火墙，注意，如果防火墙已经关闭，这个可以不用设置。 iptables -A INPUT -p udp -dport 177 -j ACCEPT6.重新加载GNOME桌面配置 init 3 或者 init 5设置到这里Xmanager3就可以连接到服务器了，但是不能使用root用户来登录。要是想让root用户来登录还需要做如下设置。1. 修改/usr/share/gdm/defaults.conf文件security# Allow root to login.It makes sense to turn this off for kiosk use, when# you want to minimize the possibility of break in.AllowRoot=true# Allow login as root via XDMCP.This value will be overridden and set to# false if the /etc/default/login file exists and contains# CONSOLE=/dev/login, and set to true if the /etc/default/login file exists# and contains any other value or no value for CONSOLE.AllowRemoteRoot=true (说明，将这行修改成true)# This will allow remote timed login.AllowRemoteAutoLogin=false# 0 is the most restrictive, 1 allo2. 修改 /etc/securetty，在文件底部添加红色部分.tty2tty3tty4tty5tty6tty7tty8tty9tty10tty11pts/0pts/1pts/2pts/3pts/43. 修改/etc/pam.d/login#%PAM-1.0#auth user_unknown=ignore success=ok ignore=ignore default=bad pam_securetty.so （将这行注释掉）auth include system-authaccount required pam_nologin.soaccount include system-authpassword include system-auth# pam_selinux.so close should be the first session rulesession required pam_selinux.so closesession include system-authsession required pam_loginuid.sosession optional pam_console.so# pam_selinux.so open should only be followed by sessions to be executed in the user contextsession required pam_selinux.so opensession optional pam_keyinit.so force revoke4. 修改/etc/pam.d/remote#%PAM-1.0#auth required pam_securetty.so（将此行注释掉）auth include system-authaccount required pam_nologin.soaccount include system-authpassword include system-auth# pam_selinux.so close should be the first session rulesession required pam_selinux.so closesession include system-authsession required pam_loginuid.sosession optional pam_console.so# pam_selinux.so open should only be followed by sessions to be executed in the user contextsession required pam_selinux.so opensession optional pam_keyinit.so force revoke5. 修改/etc/xinetd.d/telnet# default: on# description: The telnet server serves telnet sessions; it uses /# unencrypted username/password pairs for authentication.service telnet flags = REUSE socket_type = stream wait = no user = root server = /usr/sbin/in.telnetd log_on_failure+= USERID disable = no（将此行中的yes修改成n
