模拟演示

环境说明

  1. development 开发环境

  2. testing 测试环境，代码来自开发环境的合并

  3. production 生产环境，当testing环境通过测试后，将testing 合并到 主干 即成为生产环境的代码

    另外我们可以通过release功能将主干的代码复制到tags中，命名采用版本号

创建配置文件

development

部署开发代码到开发环境

cat deployment/conf/development/mydomain.com/www.conf 

REPOSITORY=git@192.168.2.1:mydomain.com/www.mydomain.com
MODE=RSYNC
OPTION="--delete --password-file=$PREFIX/conf/development/passwd"
REMOTE="jszb@192.168.2.10"
DESTINATION=mydomain.com/www.mydomain.com

创建密码文件

$ cat deployment/conf/development/passwd
eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo

testing

部署测试分支到测试环境

cat deployment/conf/testing/mydomain.com/www.conf 

REPOSITORY=git@192.168.2.1:mydomain.com/www.mydomain.com
MODE=RSYNC
OPTION="--delete --password-file=$PREFIX/conf/testing/passwd"
REMOTE="jszb@192.168.2.10"
DESTINATION=mydomain.com/www.mydomain.com

创建密码文件

$ cat deployment/conf/testing/passwd
eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo

production

部署主干代码到远程主机

cat deployment/conf/production/mydomain.com/www.conf 

REPOSITORY=git@192.168.2.1:mydomain.com/www.mydomain.com
MODE=RSYNC
OPTION="--delete --password-file=$PREFIX/conf/production/passwd"
REMOTE="jszb@192.168.2.10"
DESTINATION=mydomain.com/www.mydomain.com

创建密码文件

$ cat deployment/conf/production/passwd
eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo

配置排出列表

有时我们不希望某些文件被上传到服务器上。我们可以通过排除列表来排除上传

cat exclude/mydomain.com/www.lst
/test/phpinfo.php
/config/database.php
/backup/*.sql

配置文件管理

生产环境的安全问题，例如数据库联接信息，开发环境与测试环境的数据库是可以供发人员和测试人员随意操作的，损坏之后恢复即可，但生产环境的数据库是不能随便操作的，除运维人员其他人是不应该有权限的， 我们希望部署到生产环境的时候使用另一个配置文件，并且这个配置文件只有运维人员才能编辑。

config/database.php 将覆盖原有的配置文件，然后上传到生产环境

vim share/production/mydomain.com/www/config/database.php
...
你的数据库连接信息
...

部署前/后脚本

部署前需要做什么

$ cat libexec/mydomain.com/www/before
rsync -au $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/cn/* $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/news/
rsync -au $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/images/* $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/bbs/images/
rsync -au $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/css/* $DEPLOY_HOME/src/production/mydomain.com/www.mydomain.com/news/css

部署后需要做什么

cat libexec/mydomain.com/www/after
ssh www@192.168.1.1 "chown www:www -R /www/mydomain.com"
ssh www@192.168.1.1 "chown 700 -R /www/mydomain.com"
ssh www@192.168.1.1 "chown 777 -R /www/mydomain.com/www.mydomain.com/images/upload"

配置部署节点

在需要部署的节点上安装rsync

		
yum install xinetd rsync -y

vim /etc/xinetd.d/rsync <<VIM > /dev/null 2>&1
:%s/yes/no/
:wq
VIM

# service xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]

/etc/rsyncd.conf 配置文件

		
# cat /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 8
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log

hosts deny=*
hosts allow=192.168.2.0/255.255.255.0

[www]
    uid = www
    gid = www
    path = /www
    ignore errors
    read only = no
    list = no
    auth users = www
    secrets file = /etc/rsyncd.passwd
[mydomain.com]
    uid = www
    gid = www
    path = /www/mydomain.com
    ignore errors
    read only = no
    list = no
    auth users = mydomain
    secrets file = /etc/rsyncd.passwd
[example.com]
    uid = www
    gid = www
    path = /www/example.com
    ignore errors
    read only = no
    list = no
    auth users = example
    secrets file = /etc/rsyncd.passwd

创建密码

		
cat > /etc/rsyncd.passwd <<EOD
www:eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo
mydomain:eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo
example:eF9nJCcGKJPsiqZsfjGXxwfF41cLibTo
EOD

部署代码

[Tip]Tip

development | testing 建议使用分支管理， 而production是用master分支

开发环境部署

$ ~/deployment/run branch development mydomain.com www development 首次需要运行，切换到开发分支
$ ~/deployment/run development mydomain.com www

测试环境部署

$ ~/deployment/run branch development mydomain.com www testing 首次需要运行，切换到开发分支
$ ~/deployment/run testing mydomain.com www

如果每个bug一个分支的情况可以每次先运行

$ ~/deployment/run branch development mydomain.com www bug0005

生产环境部署

$ ~/deployment/run production mydomain.com  www

每次部署都会在服务器 /www/mydomain.com/backup/ 下备份更改的文件

回撤操作

当程序升级失败需要立即回撤到指定版本时使用

			
$ ~/deployment/run revert {development|testing|production} <domain> <host> <revision>
			
			

./run revert development mydomain www 29dd5c3de6559e2ea6749f5a146ee36cbae750a7
./run revert testing mydomain www 29dd5c3de6559e2ea6749f5a146ee36cbae750a7
./run revert production mydomain www 29dd5c3de6559e2ea6749f5a146ee36cbae750a7

发行一个版本

release 升级你的版本

$ ~/deployment/run release mydomain.com www stable-2.0

分支管理

查看当前分支

[www@manager deployment]$ ./run branch development mydomain.com www
* master

切换分支

[www@manager deployment]$ ./run branch development mydomain.com www development
HEAD is now at 461b796 提交最新代码
Branch development set up to track remote branch development from origin.
Switched to a new branch 'development'

现在已经切换到开发分支

[www@manager deployment]$ ./run branch development mydomain.com www
* development
  master

备份操作

将生产环境备份至本地

$ ~/deployment/run backup mydomain.com www /backup/2012-06-12/

日志

部署日志 deploy.YYYY-MM-DD.log, 记录部署时间与动态

 $ cat log/deploy.2012-08-03.log
