================== 代理设置 ====================

【wget】

在 /etc/wgetrc 中添加

## Wget initialization file can reside in /etc/wgetrc
## (global, for all users) or $HOME/.wgetrc (for a single user).
...
...
# You can set the default proxies for Wget to use for http and ftp.
# They will override the value in the environment.
http_proxy = http://172.16.0.1:808/proxy_user=sunf
proxy_passwd=sunf

【yum】

在 /etc/yum.conf 中添加

proxy=http://172.16.0.1:808/proxy_username=sunfei
proxy_password=sunfei

【rpm】

在 /usr/lib/rpm/macros 中设置

# This is a global RPM configuration file. All changes made here will
# be lost when the rpm package is upgraded. Any per-system configuration
# should be added to /etc/rpm/macros, while per-user configuration should
# be added to ~/.rpmmacros.
....
....
#       The port and machine name of an HTTP proxy host.
#
%_httpport 808
%_httpproxy http://172.16.0.1/

设置后没有效果。

【svn】

【git】

================== 语言设置 ====================

【如何设置显示语言】

修改/etc/sysconf/i18n文件，把LANG="zh_CN.UTF-8"修改成：

LANG="en_US.UTF-8"
或者
LANG="C"    按C语言方式显示

================== 添加 yum 仓库 ====================

通过 yum 安装 lua 时，输出如下打印

[root@Betty git-1.7.6]# yum install -y lua
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile* base: centos.ustc.edu.cn* extras: centos.ustc.edu.cn* updates: centos.ustc.edu.cn
Setting up Install Process
No package lua available.
Nothing to do
[root@Betty git-1.7.6]#

说明在已有的 repo 中找不到 lua 相关软件包，故决定添加新的 repo 。

【添加RPMforge】

1.首先查看已有的 yum repo 都有哪些。

[root@Betty yum.repos.d]# ll
total 36
-rw-r--r-- 1 root root 1926 Feb  8  2011 CentOS-Base.repo
-rw-r--r-- 1 root root  631 Feb  8  2011 CentOS-Debuginfo.repo
-rw-r--r-- 1 root root  626 Feb  8  2011 CentOS-Media.repo
-rw-r--r-- 1 root root 4663 Feb  8  2011 CentOS-Vault.repo

2.获取并安装 rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm 。

[root@Betty Me_wget]# wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

3.安装后再次查看 yum repo 。

[root@Betty yum.repos.d]# ll
total 52
-rw-r--r-- 1 root root 1926 Feb  8  2011 CentOS-Base.repo
-rw-r--r-- 1 root root  631 Feb  8  2011 CentOS-Debuginfo.repo
-rw-r--r-- 1 root root  626 Feb  8  2011 CentOS-Media.repo
-rw-r--r-- 1 root root 4663 Feb  8  2011 CentOS-Vault.repo
-rw-r--r-- 1 root root  739 Nov 13  2010 mirrors-rpmforge

-rw-r--r-- 1 root root  728 Nov 13  2010 mirrors-rpmforge-testing
-rw-r--r-- 1 root root 1113 Nov 13  2010 rpmforge.repo
[root@Betty yum.repos.d]#

重新尝试安装 lua ，这时需要的包都有了。

[root@Betty yum.repos.d]# yum list|grep lua
graphviz-lua.x86_64                        2.8-1.el5.rf                rpmforge

【添加EPEL】

1.获取并安装 epel-release-5-4.noarch.rpm

[root@Betty Me_wget]# wget http://mirrors.neusoft.edu.cn/epel/5/x86_64/epel-release-5-4.noarch.rpm
