在生产环境中,往往服务器有多台,每次增量发布都需要把代码覆盖到每台服务器上面和进行备份,这样费时又费力,所有需要有一套自动化发布的流程,我这次记录的是我在工作中用到的一套发布流程和脚本,大家可以参考学习一下.
首先,用到的是apache基金会的ant项目.
所有版本下载地址:https://archive.apache.org/dist/ant/binaries/
我这边用的是1.9.2版本
一般在生产环境中,应用目录如下:
如果没有release目录,自己新建一个.
然后将下载好的apache-ant-1.9.2放到release目录下
并在release目录下新建一个目录,取名一般为需要发布的应用服务名,用于区分,因为一台服务器可能有多个应用服务需要发布,A应用和B应用,所以需要用应用服务名来区分发布的应用
A或者B发布目录存放如下文件:
首先,done目录是存放每次需要发布的代码,格式是tgz包,代码目录需要到根目录下,一般是web目录,比如web-WEB-INF-classes-.....等等,将需要发布的包放入done下面,用打包命令进行打包 tar -zcvf A.tgz web
ant-multi-shelll.xml 文件如下 可以直接copy,不需要改动

如上,就把自动化发布的脚本都准备全了,下面需要配置一下环境变量
到/home/weblogic/目录下 我的.bash_profile文件在这个目录
命令如下
cd /home/weblogic
vim .bash_profile
新增：
ANT_HOME=/tpsys/applictions/release/apache-ant-1.9.2 [配置ANT目录]
JAVA_HOME=/usr/java/jdk1.6.0_29 [JDK目录]
PATH=$ANT_HOME/bin:$JAVA_HOME/bin:$PATH:$HOME/.local/bin:$HOME/bin
保存后执行source .bash_profile使生效
这些配置如果有多台服务器,则每台都需要配置
然后每次发布只需要将需要发布的包打成tgz包放入其中一台服务器的done目录下,
在执行 sh batch-deploy.sh done/A.tgz 就会自动将发布包分发到所有服务器进行覆盖,并且备份原代码.
最后执行重启脚本 sh batch-restart-one.sh
当发布出现问题,需要回退时候 执行 sh recover.sh
如果出现文件权限文件,请执行 chmod 777 文件名
大功告成!
