CentOS 6.x 安装 WDCP v3 后前台无法访问

错误现象

CentOS6.8安装 WDCP v3.0 后发现前台无法打开，后台 phpmyadmin 也无法访问。
检查后发现前台 Apache 启动失败。
手动重启 Apache 服务service httpd restart提示：

Starting httpd: httpd: Syntax error on line 54 of /www/wdlinux/httpd-2.2.22/conf/httpd.conf: Cannot load /www/wdlinux/httpd-2.2.22/modules/libphp5.so into server: libmhash.so.2: cannot open shared object file: No such file or directory
[FAILED]

检查原因

估计是安装时某个依赖项没有安装成功，检查安装日志发现如下错误：

内容都是http://apt.sw.be/redhat/el6/en/mirrors-rpmforge访问失败。

解决方案

Google后发现改地址已转移至http://mirrorlist.repoforge.org/el6/mirrors-rpmforge [1]
需要修改系统 yum 设置。
进入/etc/yum.repos.d/目录

cd /etc/yum.repos.d/

修改rpmforge.repo文件

vi rpmforge.repo

文件原内容大概如下：

### Name: RPMforge RPM Repository for RHEL 6 - dag
### URL: http://rpmforge.net/
[rpmforge]
name = RHEL $releasever - RPMforge.net - dag
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/rpmforge
mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
[rpmforge-extras]
name = RHEL $releasever - RPMforge.net - extras
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/extras
mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge-extras
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-extras
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
[rpmforge-testing]
name = RHEL $releasever - RPMforge.net - testing
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/testing
mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge-testing
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-testing
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

文件中有三处需要修改：

①

mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge-extras

修改为

mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge

②

mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge-extras

修改为

mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge-extras

③

mirrorlist = http://apt.sw.be/redhat/el6/en/mirrors-rpmforge-testing

修改为

mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge-testing

修改完成后按 Esc 然后保存退出:wq。
再次yum update 即可成功。
由于之前 WDCP 安装过程中出错，所以有些组件没有安装成功，根据错误提示找到安装脚本中的相关内容如下：

if [ $v1 == 0 ];then
    RF="lanmp_wdcp-2-5.$arch.rpm";
elif [ $v2 == 0 ];then
    RF="lanmp_wdcp-2-5.el6.$arch.rpm";
    if [ $arch == "x86_64" ];then
        wget -c http://dl.wdlinux.cn/rpms/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
        rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm 
    else
        wget -c http://dl.wdlinux.cn/rpms/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
        rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm 
    fi
    yum install -y mhash-devel libmcrypt-devel
else
    echo
    echo "The current system does not support"
    echo
    exit

出错导致mhash-devel与libmcrypt-devel没有安装，手动安装即可：

yum install -y mhash-devel libmcrypt-devel

安装成功后手动启动前台 Apache 服务：

[root@cloud ~]# service httpd start
Starting httpd: [  OK  ]

启动成功，前台与 phpmyadmin 都能正常打开了。
