–with-ssl-dir=/usr/share/ssl \
–with-zlib \
–with-pam \
–with-md5-passwords \
–with-kerberos5 \# 编译

RHEL 5.4 Add/Remove Packages 添加/删除软件包
十一 30th
RHEL 5.4 Add/Remove Packages 添加/删除软件包（自动处理依赖关系）
1. 设置本地光盘yum源
vi /etc/yum.repos.d/cdrom.repo
[cdrom]
enabled = 1
name = cdrom
baseurl = file:///mnt/cdrom/Server
gpgcheck = 0
注意: 如果 baseurl 只写 file:///mnt/cdrom/ 将会报错:
“No such file or directory: repomd.xml”
“Unable to retrieve software information”
因为无法找到: repomd.xml 文件
2. 配置 yum repo 配置文件
vi /usr/lib/python2.4/site-packages/yum/yumRepo.py
查找:
remote = url + ‘/’ + relative
替换:
remote = “/mnt/cdrom” + ‘/’ + relative
3. 挂载光盘 (DVD)
mount /dev/cdrom /mnt/cdrom
4. 清除 yum 缓存.更新 yum
yum clean all
yum update
5. 运行 system-config-packages 配置工具
system-config-packages
CentOS yum – CentOS-Base.repo
九 21st
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
