CentOS上SSH客户端PAC Manager的安装流程讲解
对于在 Windows 上经常需要远程管理 Linux 服务器的 SA 们来说，也许会觉得 SecureCRT 非常好用，因为它是一个强大的 SSH 帐号管理工具，而且可以记住密码，但这个是收费软件。而现在如果你想在 CentOS 上也需要这样一款软件的话，那么 PAC Manager 也许正是你要寻找，它是一款非常不错的替代品，而且完全开源免费。
功能：
1.支持远程及本地宏命令。
2.支持 EXPECT 批处理。
3.支持代理。
4.支持集群连接。
5.支持标签或窗口。
6.批量帐号管理等等。

我下载的是：pac-4.5.3.5-2.x86_64.rpm
执行命令安装：
复制代码
代码如下:
rpm -ivh pac-4.5.3.5-2.x86_64.rpm
但是报出如下错误：
error: Failed dependencies:

说明缺了不少的信赖，依次安装。
首先安装 epel 源，这个因为先前我装其它软件的时候装过了，这里就不装了：
rpm -ivh pac-4.5.3.5-2.x86_64.rpm
但是报出如下错误：

说明缺了不少的信赖，依次安装。
首先安装 epel 源，这个因为先前我装其它软件的时候装过了，这里就不装了：
复制代码
代码如下:
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm<／pre>
安装依赖：
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm<／pre>
安装依赖：
复制代码
代码如下:
# yum install ftp perl-Crypt-Blowfish perl-Crypt-CBC perl-Crypt-Rijndael perl-Digest-SHA perl-Expect perl-Gtk2 perl-IO-Stty perl-Net-ARP perl-YAML perl-Cairo perl-Glib perl-IO-Tty perl-Pango uuid-perl
perl-Gnome2-GConf perl-Gtk2-Ex-Simple-List perl-Gtk2-GladeXML 这三个包不在源内，下载下来手工安装：
# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/perl-Gnome2-GConf-1.044-1.el6.rf.x86_64.rpm
# wget http://li.nux.ro/download/nux/dextop/el6/i386/perl-Gtk2-Ex-Simple-List-0.50-13.el6.nux.noarch.rpm
# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/perl-Gtk2-GladeXML-1.007-1.el6.rf.x86_64.rpm
# rpm -ivh perl-Gnome2-GConf-1.044-1.el6.rf.x86_64.rpm perl-Gtk2-Ex-Simple-List-0.50-13.el6.nux.noarch.rpm perl-Gtk2-GladeXML-1.007-1.el6.rf.x86_64.rpm
以上是网上说的一些信赖，但是我在实际安装的时候，发现还缺少下面的信赖：
perl(Socket6) is needed by pac-4.5.3.5-2.x86_64
perl(Time::HiRes) is needed by pac-4.5.3.5-2.x86_64
telnet is needed by pac-4.5.3.5-2.x86_64
继续安装：
# yum install ftp perl-Crypt-Blowfish perl-Crypt-CBC perl-Crypt-Rijndael perl-Digest-SHA perl-Expect perl-Gtk2 perl-IO-Stty perl-Net-ARP perl-YAML perl-Cairo perl-Glib perl-IO-Tty perl-Pango uuid-perl

perl(Time::HiRes) is needed by pac-4.5.3.5-2.x86_64
telnet is needed by pac-4.5.3.5-2.x86_64
继续安装：
复制代码
代码如下:
yum install perl-Socket6
yum install perl-Time-HiRes
yum install telnet
安装完成，再继续执行命令：
yum install perl-Socket6
yum install perl-Time-HiRes
yum install telnet
安装完成，再继续执行命令：
复制代码
代码如下:
rpm -ivh pac-4.5.3.5-2.x86_64.rpm
安装成功，可以使用了。
rpm -ivh pac-4.5.3.5-2.x86_64.rpm
安装成功，可以使用了。
在实际的使用中，发现ssh连接很慢，而且要在connection的proxy中，勾选Never use any proxy for this connection，不然会连接不上，系统中并没有设置代理，原因不明。
