塘下网站建设公司,东莞网站页设计制作,分析网站统计对网络营销的价值,一个网站的开发周期测试配置yum仓库的http镜像一、基础环境
1、在tvm-base的基础上#xff0c;复制一个镜像为tvm-yum来测试。
2、网络#xff1a;
eth0#xff1a;host-only#xff08;用于虚拟内网#xff0c;手动固定IP#xff0c;这样从宿主机可以直接连接到这个vm#xff09;
eth1复制一个镜像为tvm-yum来测试。
2、网络
eth0host-only用于虚拟内网手动固定IP这样从宿主机可以直接连接到这个vm
eth1NAT用于上外网动态IP

0.0.0.0 10.0.3.2 0.0.0.0 UG 0 0 0 eth13、配置这台服务器为ntp和dns服务器涉及
1ntp服务防火墙放行udp 123
使用脚本配置https://github.com/opera443399/ops/blob/master/bin/linux/init_datetime.sh
[roottvm-yum ~]# sh init_datetime.sh s2dnsmasq服务 防火墙放行udp 53
[roottvm-yum ~]# yum -y install dnsmasq
将涉及域名写入hosts文件
[roottvm-yum ~]# cat /etc/hosts |grep -v localhost
127.0.0.1 tvm-yum
192.168.56.254 mirrors.office.test
192.168.56.254 ntp.office.test
192.158.56.252 cobbler.office.test启动服务
[roottvm-yum ~]# service dnsmasq start
增加到开机启动
[roottvm-yum bin]# chkconfig dnsmasq on二、配置web服务
1、防火墙放行80端口
2、配置httpd
若没有禁用selinux则应当这样配置
[roottvm-yum ~]# chcon -Rv --typehttpd_sys_content_t /data/yum/repo/
否则直接禁用selinux[roottvm-yum ~]# yum -y install httpd
调整httpd的配置
[roottvm-yum ~]# cat /etc/httpd/conf/httpd.conf |grep ServerName |grep ^[^#]
ServerName 127.0.0.1虚拟主机
[roottvm-yum ~]# mv /etc/httpd/conf.d/welcome.conf /tmp/
[roottvm-yum ~]# cat /etc/httpd/conf.d/mirrors.office.test.conf
VirtualHost *:80ServerAdmin pcoffice.testServerName mirrors.office.testDocumentRoot /data/yum/repoErrorLog logs/mirrors.office.test-error_logCustomLog logs/mirrors.office.test-access_log commonDirectory /data/yum/repooptions Indexes FollowSymLinksAllowOverride NoneOrder allow,denyAllow from all/Directory
/VirtualHost3、启动httpd服务
[roottvm-yum ~]# chown -R apache:apache /data/yum/repo
[roottvm-yum ~]# service httpd start接下来需要
1配置一个local yum 镜像并定时从公网的mirrors同步数据。
注1不需要i386目录此处只用x86_64的版本。
注2不需要isos目录里面存放的是iso文件。
注3不需要ppc64目录里面是powerpc架构的。
2提供local-office.repo文件供客户端用。三、配置目录和脚本制作本地的yum镜像
[roottvm-yum ~]# mkdir -p /data/yum/repo/{centos,epel}/6 /data/download/ /data/ops/bin/
1、从iso文件拷贝内容。本机目前只有CentOS-6.5的版本当然应该用6.6的更佳。
2种方式
1上传iso文件到/data/download/2也可以直接挂载光碟[roottvm-yum ~]# ls /data/download/
CentOS-6.5-x86_64-bin-DVD1.iso CentOS-6.5-x86_64-bin-DVD2.iso[roottvm-yum ~]# mkdir -p /data/yum/repo/centos/6/os/x86_642、同步iso文件中的内容
[roottvm-yum ~]# mount -ro loop /data/download/CentOS-6.5-x86_64-bin-DVD1.iso /mnt
[roottvm-yum ~]# rsync -avHPS /mnt/ /data/yum/repo/centos/6/os/x86_64/
[roottvm-yum ~]# umount /mnt
[roottvm-yum ~]# mount -ro loop /data/download/CentOS-6.5-x86_64-bin-DVD2.iso /mnt
[roottvm-yum ~]# rsync -avHPS /mnt/ /data/yum/repo/centos/6/os/x86_64/
[roottvm-yum ~]# umount /mnt3、测试httpd服务的访问
访问
http://mirrors.office.test/centos抓包信息
[roottvm-yum ~]# curl -o /dev/null -v -I http://mirrors.office.test/centos/
* About to connect() to mirrors.office.test port 80 (#0)

Remote Address:192.168.56.254:80

这里我选择了一个支持rsync协议的镜像
http://mirrors.ustc.edu.cn/centos/可以在搜索引擎搜索“rsync epel 6/x86_64/”这类关键词来找mirros当然这里也有一个centos的列表
http://www.centos.org/download/mirrors/配置脚本同步并放到crontab中定时执行
----------------------------------------
[roottvm-yum bin]# cat repo_update.sh
#!/bin/bash
#
# 2015/7/17f_log/tmp/repo_update_run.logif [ -f /var/lock/subsys/repo_update ]; thenecho [date] 同步任务已经在执行中。 ${f_log}exit 0
fid_centos/data/yum/repo/centos/6

echo [date] 开始同步centos ${f_log}
rsync -avzP --delete --delete-excluded --exclude isos --exclude i386 rsync://mirrors.ustc.edu.cn/centos/6/ /data/yum/repo/centos/6/ 2${f_log}

echo [date] 操作结束。 ${f_log} rm /var/lock/subsys/repo_update
echo [date] 完成本次任务。 ${f_log} chown -R apache:apache /data/yum/repo----------------------------------------放到crontab中
[roottvm-yum ~]# cat _NTP /var/spool/cron/root
# repo update
0 4 * * * /bin/bash /data/ops/bin/repo_update.sh /tmp/repo.log 21
_NTP先手动执行一次
[roottvm-yum ~]# /bin/bash /data/ops/bin/repo_update.sh /tmp/repo.log 21 5、提供一个office源供自定义的安装包含企业定制rpm包新版本的开源软件的rpm包
[roottvm-yum ~]# yum install createrepo
[roottvm-yum ~]# mkdir -p /data/yum/repo/office/centos/6/x86_64
[roottvm-yum ~]# cd /data/yum/repo/office/6/x86_64
[roottvm-yum x86_64]# wget 还可以一次下载多个rpm包
[roottvm-yum ~]# wget --execute robotsoff -nc -nd -r -l1 -A*.rpm http://download.gluster.org/pub/gluster/glusterfs/3.6/LATEST/CentOS/epel-6/x86_64/ 使用createrepo工具
[roottvm-yum x86_64]# createrepo .
[roottvm-yum ~]# cd -
[roottvm-yum ~]# chown -R apache:apache /data/yum/repo 6、提供local-office.repo文件
现有的目录
[roottvm-yum ~]# tree /data/yum/repo/ -L 3
/data/yum/repo/

/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 这个key一开始是不存在的这里由http服务来提供在repo文件中指向到对应的URL
gpgkeyhttp://mirrors.office.test/epel/RPM-GPG-KEY-EPEL-$releaseverGPG-KEY在这里
[roottvm-yum ~]# cp /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 /data/yum/repo/centos/
[roottvm-yum ~]# cp /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 /data/yum/repo/epel/
默认安装centos后已经有了RPM-GPG-KEY-CentOS-6RPM-GPG-KEY-EPEL-6可以通过安装公网的epel源来获取
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm当然了我们应该移除现有的repo文件仅使用上面提供的自己的repo配置即可
【在本地】
[roottvm-yum ~]# mv /etc/yum.repos.d/*.repo /tmp/
[roottvm-yum ~]# cp /data/yum/repo/local-office.repo /etc/yum.repos.d/local-office.repo
【在客户端】
[roottvm-rpm ~]# mv /etc/yum.repos.d/*.repo /tmp/ \wget http://mirrors.office.test/local-office.repo -O /etc/yum.repos.d/local-office.repo \yum clean all \yum makecache四、等mirros同步完成后开始测试
1、本机测试
先清除缓存
[roottvm-yum ~]# yum clean all
Loaded plugins: fastestmirror, security
Cleaning repos: base extras updates
Cleaning up Everything
Cleaning up list of fastest mirrors试着更新下系统
[roottvm-yum ~]# yum update

[roottvm-yum ~]#
[roottvm-yum ~]# cat /etc/issue
CentOS release 6.6 (Final)
Kernel \r on an \m2、瞧已经升级到6.6的版本建议reboot一下先。
reboot前先将httpd服务加入开机启动。
[roottvm-yum centos]# chkconfig httpd on
[roottvm-yum centos]# chkconfig --list |grep httpd
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off用update升级系统后在/etc/yum.repos.d/里面更新了CentOS相关的repo文件因此在重启后可以考虑移除
[roottvm-yum ~]# mv -f CentOS-* /etc/yum.repos.d/ /tmp/五、客户端使用local-office.repo文件
[roottvm-rpm ~]# yum update
符合预期。
[roottvm-rpm ~]# yum install nginx
[roottvm-test conf.d]# nginx -v
nginx version: nginx/1.8.0
符合预期。ZYXW、参考
