# 搭建Auto-builder服务器过程记录
|
||
|
||
## 1 概述
|
||
|
||
由于原编译机服务器硬盘损坏，导致数据丢失。查阅文档记录并不全面，只能尝试重新搭建。现搭建时进行详细记录搭建过程。便于后来实施人员重搭环境及测试。
|
||
|
||
## 2 基础环境搭建及配置
|
||
|
||
### 2.1 系统安装及基本配置
|
||
|
||
root口令builder，配置默认root登录，配置ssh可root登录，配置双网卡bonding
|
||
|
||
分区:(50G / ，32G swap ，两个50G空闲分区 ，剩下的挂/home)
|
||
|
||
```
|
||
root@rocky:/home# parted -l
|
||
Model: ATA ST2000DM001-1ER1 (scsi)
|
||
Disk /dev/sda: 2000GB
|
||
Sector size (logical/physical): 512B/4096B
|
||
Partition Table: gpt
|
||
|
||
Number Start End Size File system Name Flags
|
||
1 17.4kB 50.0GB 50.0GB ext3
|
||
2 50.0GB 100GB 50.0GB ext3
|
||
3 100GB 132GB 32.0GB linux-swap(v1)
|
||
4 132GB 182GB 50.0GB ext3
|
||
5 182GB 2000GB 1818GB ext3
|
||
|
||
```
|
||
|
||
### 2.2 安装kvm虚拟机
|
||
|
||
kvm（kernel-based virtual machine）安装： 配置源、安装包。
|
||
|
||
#### 2.2.1 配置源
|
||
|
||
配置/etc/apt/sources.list，配置完后执行apt-get update
|
||
|
||
```
|
||
deb http://172.16.0.234/debian squeeze main contrib non-free
|
||
deb-src http://172.16.0.234/debian squeeze main contrib non-free
|
||
deb http://172.16.0.234/sid squeeze main
|
||
deb-src http://172.16.0.234/sid squeeze main
|
||
```
|
||
#### 2.2.2 安装kvm包
|
||
|
||
```
|
||
root@rocky:/home# aptitude install libvirt-bin
|
||
libvirt-dev python-libvirt virt-top virtinst virt-manager qemu-kvm
|
||
|
||
```
|
||
|
||
#### 2.2.3 安装虚拟机
|
||
|
||
virt-manager启动kvm安装虚拟机。
|
||
|
||
分配100G“/”,4096M内存，配置默认有root登录，注意需update-grub2。
|
||
|
||
#### 2.2.4 虚拟机网络配置
|
||
|
||
配置桥接（gw：172.16.250.1 ip：172.16.250.220）：
|
||
|
||
在virt-manager启动的图形界面上点击：虚拟机管理器--编辑--主机详情--虚拟网络（左下方“+”）--创建虚拟网络--输入“虚拟网络名”--选择ipv4地址空间“172.16.250.0/24”--前进到连接到物理网络,选择“转发到物理网络（NAT）”
|
||
|
||
在单独的虚拟机图形界面上点击：选择虚拟机--显示虚拟机硬件详情--选择虚拟网络接口（e1000）
|
||
|
||
### 2.3 配置nfs共享
|
||
|
||
#### 2.3.1 开机启动服务
|
||
|
||
在172.16.0.250上，添加开机启动服务
|
||
|
||
```
|
||
chkconfig portmap on
|
||
chkconfig nfs-common on
|
||
chkconfig nfs-kernel-server on
|
||
```
|
||
|
||
#### 2.3.2 配置nfs服务器
|
||
|
||
创建目录/home/builder，配置/etc/exports
|
||
|
||
```
|
||
root@rocky:/home/builder# cat /etc/exports
|
||
# /etc/exports: the access control list for filesystems which may be exported
|
||
# to NFS clients. See exports(5).
|
||
#
|
||
# Example for NFSv2 and NFSv3:
|
||
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
|
||
#
|
||
# Example for NFSv4:
|
||
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
|
||
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
|
||
#
|
||
/home/builder 172.16.250.220(rw,anonuid=1001,anongid=1001,sync,no_subtree_check,no_root_squash)
|
||
```
|
||
手动启动nfs服务器
|
||
|
||
```
|
||
/etc/init.d/portmap start
|
||
/etc/init.d/nfs-common start
|
||
/etc/init.d/nfs-kernel-server start
|
||
|
||
```
|
||
|
||
#### 2.3.3 配置nfs客户端
|
||
|
||
在172.16.250.220虚拟机上，创建目录/home/builder，修改配置/etc/fstab配置开机挂载（在最后添加一行）：
|
||
|
||
```
|
||
localhost:~ # cat /etc/fstab
|
||
#
|
||
# /etc/fstab: static file system information
|
||
#
|
||
# <file system> <dir> <type> <options> <dump> <pass>
|
||
|
||
devpts /dev/pts devpts defaults 0 0
|
||
sysfs /sys sysfs defaults 0 0
|
||
proc /proc proc defaults 0 0
|
||
#tmp /tmp tmpfs defaults 0 0
|
||
tmpfs /dev/shm tmpfs defaults 0 0
|
||
#usb /proc/bus/usb usbdevfs defaults 0 0
|
||
|
||
UUID=b253098b-da2c-4b5b-adde-3a4c2a227a48 / ext3 acl 0 1
|
||
172.16.0.250:/home/builder /home/builder nfs nolock 0 0
|
||
```
|
||
|
||
注意：重启测试，未挂载，需在/etc/rc.d/rc.local中添加mount -a
|
||
|
||
|
||
### 2.4 配置ssh服务
|
||
|
||
配置250编译服务器可root登录，生成密钥对，配置和编译虚拟机的等效性。
|
||
|
||
#### 2.4.1 生成密钥对
|
||
|
||
在172.16.0.250上，生成ssh密钥对。
|
||
|
||
```
|
||
root@rocky:~/.ssh# ssh-keygen
|
||
Generating public/private rsa key pair.
|
||
Enter file in which to save the key (/root/.ssh/id_rsa):
|
||
/root/.ssh/id_rsa already exists.
|
||
Overwrite (y/n)? y
|
||
Enter passphrase (empty for no passphrase):
|
||
Enter same passphrase again:
|
||
Your identification has been saved in /root/.ssh/id_rsa.
|
||
Your public key has been saved in /root/.ssh/id_rsa.pub.
|
||
The key fingerprint is:
|
||
49:1c:2f:41:a7:b7:6f:e0:72:36:60:07:a1:9c:81:19 root@rocky
|
||
The key's randomart image is:
|
||
+--[ RSA 2048]----+
|
||
| E+..= . |
|
||
| o. = B |
|
||
| + * o |
|
||
| . = . |
|
||
| S + |
|
||
| . + o |
|
||
| . = o |
|
||
| + o |
|
||
| |
|
||
+-----------------+
|
||
root@rocky:~/.ssh#
|
||
```
|
||
#### 2.4.2 设置等效性
|
||
|
||
```
|
||
root@Auto-builder:~/.ssh# cp id_rsa.pub authorized_keys
|
||
root@Auto-builder:~/.ssh# ls
|
||
authorized_keys id_rsa id_rsa.pub known_hosts
|
||
root@Auto-builder:~/.ssh#
|
||
|
||
```
|
||
|
||
配置完172.16.0.250服务器后，配置172.16.250.220虚拟机。将服务器上的.ssh目录拷贝到虚拟机的root家目录下即可。
|
||
|
||
### 2.5 配置gitlab用户
|
||
|
||
此处使用原有用户linx6.0.42builder@linx-info.com口令rockyrocky
|
||
|
||
只需添加新的ssh公钥即可。
|
||
|
||
使用原有的linx6.0.42builder@linx-info.com登录后，在个人配置里将密钥配置里原有的公钥删除，添加新的公钥（前一节做出的ssh密钥对的id_rsa.pub）。
|
||
|
||
在172.16.0.250上测试配置好gitlab库的配置。git clone一个用户有权限的库测试：
|
||
|
||
```
|
||
root@Auto-builder:~# git clone git@gitlab.rd.in.linx:linx6.0.42/autobuild-tools.git
|
||
Cloning into autobuild-tools...
|
||
The authenticity of host 'gitlab.rd.in.linx (172.17.150.10)' can't be established.
|
||
RSA key fingerprint is 3a:0d:22:14:a2:21:8b:9d:52:12:57:c9:7a:0e:6a:3c.
|
||
Are you sure you want to continue connecting (yes/no)? yes
|
||
Warning: Permanently added 'gitlab.rd.in.linx,172.17.150.10' (RSA) to the list of known hosts.

登录编译虚拟机，测试git clone。克隆失败如下。
|
||
|
||
```
|
||

```
|
||
|
||
此时现象为可以ping通，但解析不了域名。需配置resolv.conf。
|
||
|
||
```
|
||
localhost:/home/builder/x86_64 # cat /etc/resolv.conf
|
||
#
|
||
# /etc/resolv.conf: resolver configuration file
|
||
#
|
||
|

|
||
domain in.linx
|
||
|
||
# End of file
|
||
localhost:/home/builder/x86_64 #
|
||
```
|
||
|
||
再进行clone测试，成功。
|
||
|
||
## 3 布置自动编译环境及测试调试
|
||
|
||
关于自动编译虚拟机的搭建及配置，可以参考文档《linx6.0.42.41自动编译环境搭建说明》
|
||
|
||
文档所在git库连接地址： http://gitlab.rd.in.linx/linx6.0.42/documents/blob/master/autobuild.md
|
||
|
||
### 3.1 布置自动编译环境
|
||
|
||
在编译虚拟机上执行以下操作
|
||
|
||
#### 3.1.1 创建工作目录
|
||
|
||
```
|
||
# mkdir -p /home/x86_64-workdir
|
||
```
|
||
|
||
克隆autobuild-tools.git
|
||
|
||
```
|
||
# git clone git@gitlab.rd.in.linx:linx6.0.42/autobuild-tools.git
|
||
```
|
||
|
||
使用工具获取相关git库（等待执行结束即可）
|
||
|
||
```
|
||
# ./autobuild-tools/build-pkg/pre.sh
|
||
```
|
||
|
||
在编译机上，获取chroot_x86_64_git最小环境的git库，并准备好最小环境。
|
||
|
||
```
|
||
# cd /home/x86_64-workdir
|
||
# git clone git@gitlab.rd.in.linx:chroot_git/chroot_x86_64_git.git
|
||
# cd chroot_x86_64_git
|
||
# ./preps.sh
|
||
```
|
||
|
||
创建日常编译、日常编译发布版、发布正式版、虚拟机默认安装等目录。
|
||
|
||
目录如下：
|
||
|
||
```
|
||
localhost:/home/builder # find .
|
||
.
|
||
./x86_64
|
||
./x86_64/2015-12-16-005001
|
||
./x86_64/2015-12-16-005001/pkgRecord
|
||
./x86_64/2015-12-16-005001/pkgRecord/base
|
||
./x86_64/2015-12-16-005001/pkgRecord/security
|
||
./x86_64/2015-12-16-005001/commitRecord
|
||
./x86_64/2015-12-16-005001/cfg
|
||
./x86_64/2015-12-16-005001/cfg/iso_env
|
||
./x86_64/2015-12-16-005001/cfg/sys_env
|
||
./x86_64/2015-12-16-005001/cfg/xmlDir
|
||
./kvm_autocreate
|
||
./kvm_autocreate/mnt
|
||
./kvm_autocreate/kvmimage
|
||
./stable-iso
|
||
./stable-iso/4.2-i686-builds
|
||
./stable-iso/4.2-x86_64-builds
|
||
./daily-builds
|
||
./daily-builds/4.2-i686-builds
|
||
./daily-builds/4.2-x86_64-builds
|
||
./daily-builds/4.2-x86_64-builds/20151216
|
||
./daily-builds/4.2-x86_64-builds/isoUpdates
|
||
localhost:/home/builder #
|
||
```
|
||
|
||
#### 3.1.2 添加git检测记录
|
||
|
||
为执行编译创建了/home/builder/x86_64/2015-12-16-005001/commitRecord/applications,applications文件中存放了上次发布版20150911的applications的git commit提交。此commitRecord目录下应该有所有要集成的git库的某一日期的commit记录（此时为测试记录，暂未添加别的）。因为检测是否更新包出盘的脚本中，是以检测commit是否有新提交来决定是否编包出盘的。
|
||
|
||
```
|
||
localhost:/home/builder # cat ./x86_64/2015-12-16-005001/commitRecord/applications
|
||
x86_64:dedff700fda645fe2117f67d1c26347dc3b04ecc
|
||
|
||
```
|
||
|
||
添加各个库的最新的git commit记录到信息记录的文件中，与上述application一样。到/home/x86_64-workdir/autobuild-tools/git_dir/git下的各个git库中，git log获取最新的git commit提交，写入配置文件中。如下：
|
||
|
||
```
|
||
localhost:/home/x86_64-workdir/autobuild-tools/build-pkg # ls /home/builder/x86_64/2015-12-17-015346/commitRecord/*
|
||
/home/builder/x86_64/2015-12-17-015346/commitRecord/applications
|

|
||
localhost:/home/x86_64-workdir/autobuild-tools/build-pkg #
|
||
|
||
```
|
||
|
||
#### 3.1.3 测试自动检测编译
|
||
|
||
将上次正式版发布的iso，挂载拷贝里面的安装包到/home/builder/x86_64/2015-12-16-005001/pkgRecord/security中。
|
||
|
||
在编译机执行auto_gitcheck.sh测试编译。(此时应该已可以检测编译，但是无法出盘)
|
||
|
||
```
|
||
|
||
localhost:/home/x86_64-workdir # ./autobuild-tools/build-pkg/auto_gitcheck.sh -m
|
||
localhost:/home/x86_64-workdir #
|
||
|
||
```
|
||
|
||
添加自动检测编译到开机启动rc.local中。如下，rc.local中最后一句。
|
||
|
||
```
|
||
localhost:/home/x86_64-workdir # cat /etc/rc.d/rc.local
|
||
#!/bin/sh
|
||
#
|
||
# This script will be executed *after* all the other init scripts.
|
||
# You can put your own initialization stuff in here if you don't
|
||
# want to do the full Sys V style init stuff.
|
||
mount -a
|
||
echo 1 > /proc/sys/kernel/sysrq
|
||
|
||
nohup /home/x86_64-workdir/autobuild-tools/build-pkg/auto_gitcheck.sh >> /home/x86_64-workdir/auto_gitcheck.log &
|
||
```
|
||
|
||
### 3.2 配置环境至出盘
|
||
|
||
#### 3.2.1 查看如何得到base包
|
||
|
||
查看文档《Rocky6.0.42版本构建工具说明文档V0.1.pdf》中get_mkiso_info工具说明，在之前测试编译出的目录/home/builder/x86_64/2015-12-17-015346中的cfg中有光盘环境包列表和系统环境包列表。
|
||
|
||
根据光盘环境包列表，开始着手编译base包集合。
|
||
|
||
查看原来的记录文档及说明文档。没有此类包如何得到及特殊编译的记录。
|
||
|
||
首先，手动编译base包kernel
|
||
|
||
git clone git@gitlab.rd.in.linx:linx6.0.42/kernel.git
|
||
|
||
在6.0系统中编译。此处，是在172.16.0.250服务器上进行编译的。（注意：此时才发现，此250服务器需要使用gdzhang的key，因为编译kernel需要从172.16.0.4获取包，只有gdzhang的key可以使用）
|
||
|
||
执行编译，在/tmp/work中可找到编译完成的包等：
|
||
|
||
```
|
||
root@Auto-builder:/home/sxxu/kernel/kernel# ./build.sh -a x86_64
|
||
-v 2.6.32.41 -b
|
||
```
|
||
|
||
拷贝编译好的内核到base目录下，拷贝光盘环境的所有包（除了内核）到base目录下。
|
||
|
||
注意：此时使用的base包的其他所有包，均来自查找原来的备份所得。（备份包为原swei的本机硬盘备份）
|
||
|
||
#### 3.2.2 添加mkiso所需的tag
|
||
|
||
查看auto_gitcheck.sh脚本及之前的log，可以运行到mkiso。查看mkiso脚本，MINOR_VERSION需要配置/home/builder/$ARCH的git tag。
|
||
|
||
在/home/builder/x86_64下创建git库，提交git tag
|
||
|
||
```
|
||
localhost:/home/builder/x86_64 # git init
|
||
Initialized empty Git repository in /home/builder/x86_64/.git/

## 4 发布环境布置
|
||
|
||
### 4.1 配置apache服务器
|
||
|
||
重装apache的包，首先将原来的apache的包全部卸载，然后配置源/etc/apt/sources.list，只配置debian源。安装debian源里的apache包。
|
||
|
||
卸载包，更新源为debian源后，再重新安装：
|
||
|
||
```
|
||
root@Auto-builder:~# aptitude purge apache2
|
||
root@Auto-builder:~# aptitude purge apache2.2-common apache2.2-bin apache2-mpm-prefork
|
||
root@Auto-builder:~# apt-get update
|
||
root@Auto-builder:~# aptitude install apache2
|
||
```
|
||
|
||
修改apache配置文件/etc/apache2/httpd.conf(添加servername)
|
||
|
||
修改apache配置文件/etc/apache2/sites-enabled/000-default(指定headername)
|
||
|
||
拷贝apache浏览器界面配置文件到/var/www下(github-markdown.css footer.html)，修改footer.html。
|
||
|
||
注意，改完配置，启动或重启apache服务。
|
||
|
||
### 4.2 配置邮件发送服务
|
||
|
||
创建邮件服务器用户Auto-builder，设置sudo权限NOPASSWD：ALL
|
||
|
||
postfix服务配置，安装包heirloom-mailx，注意查看/tmp的权限为777。
|
||
|
||
postfix配置文件/etc/postfix/main.cf
|
||
|
||
```
|
||
root@Auto-builder:/etc/postfix# cat main.cf
|
||
myhostname = Auto-builder
|
||
alias_maps = hash:/etc/aliases
|
||
alias_database = hash:/etc/aliases
|
||
mydestination = Auto-builder, localhost.localdomain, , localhost
|
||
relayhost =
|
||
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
|
||
mailbox_command = procmail -a "$EXTENSION"
|
||
mailbox_size_limit = 0
|
||
recipient_delimiter = +
|
||
inet_interfaces = all
|
||
inet_protocols = ipv4
|
||
|
||
root@Auto-builder:/etc/postfix#
|
||
```
|
||
|
||
设置postfix开机自启动chkconfig postfix on
|
||
|
||
测试发送邮件：
|
||
|
||
```
|
||
root@Auto-builder:/etc/postfix# su - Auto-builder
|
||
没有目录，将以 HOME=/ 登录
|
||
Auto-builder@Auto-builder:/$ touch /tmp/111
|
||
Auto-builder@Auto-builder:/$ sudo -u Auto-builder mail -s "test1" sxxu@linx-info.com < /tmp/111
|
||
```
|
||
|
||
## 5 测试调试
|
||
|
||
基本配置如上所述。之后可进行git库更新测试调试。
|
||
|
||
## 6 后期使用添加补充
|
||
|
||
### 6.1 添加nbd模块加载
|
||
|
||
经测试调试，发现安装虚拟机会出错。原因是未加载nbd设备。导致配置已经初始化的kvm_install.img失败。
|
||
|
||
修改250服务器的rc.local，添加开机启动加载nbd设备，如下：
|
||
|
||
```
|
||
root@Auto-builder:~# cat /etc/modules
|
||
# /etc/modules: kernel modules to load at boot time.
|
||
#
|
||
# This file contains the names of kernel modules that should be loaded
|
||
# at boot time, one per line. Lines beginning with "#" are ignored.
|
||
# Parameters can be specified after the module name.
|
||
|
||
loop
|
||
linx_sec
|
||
linx_sysinfo
|
||
|
||
nbd max_part=8
|
||
|
||
```
|
||
|
||
### 6.2 出盘发布时间变化
|
||
|
||
多次出盘时间定在09:00左右。查看发现，编译虚拟机的时间不对。配置编译虚拟机的对时任务，配置250服务器的ntp对时服务。
|
||
|
||
虚拟机对时任务配置：（添加对时脚本，配置定时任务）
|
||
|
||
```
|
||
localhost:/var/log # ls /usr/sbin/update_time.sh -l
|
||
-rwxr-xr-x 1 sysadmin sysadmin 181 1月 29 11:53 /usr/sbin/update_time.sh
|
||
localhost:/var/log # cat /usr/sbin/update_time.sh
|
||
#!/bin/bash
|
||
NTPSERVER_A='172.16.0.250'
|
||
NTPSERVER_B=''
|
||
NTPDATE='/usr/sbin/ntpdate'
|
||
${NTPDATE} ${NTPSERVER_A}
|
||
#${NTPDATE} ${NTPSERVER_A} || ${NTPDATE} ${NTPSERVER_B}
|
||
/sbin/hwclock -w
|
||

|
||
#
|
||

|
||
#
|
||
|
||

|
||
SHELL=/bin/bash
|
||
PATH=/bin:/sbin:/usr/bin:/usr/sbin
|
||

|
||
|
||
*/1 * * * * sysadmin /usr/sbin/update_time.sh
|
||
|
||
```
|
||
|
||
服务器ntp对时服务配置：（ntp服务默认是开机启动）
|
||
|
||
```
|
||
root@Auto-builder:~# cat /etc/ntp.conf
|
||
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
|
||
|
||
driftfile /var/lib/ntp/ntp.drift
|
||
|
||
|
||
# Enable this if you want statistics to be logged.
|
||
#statsdir /var/log/ntpstats/
