PHP コードはオンラインでバージョン切り替えを実現します

以下为现有php业务，代码上线方式。实现：4套环境版本切换。

[root@hz-web-01 htdocs]# cat release.sh#!/usr/bin/env bash work_dir=/mnt/var/www/htdocsrelease_dir=/var/www/htdocs # app environmentapp_env=$1# build release file pathbuild_file_path=$2 help() {   echo   echo usage: ${0##*/} [app_env] [build_file_path]   echo example: ${0##*/} int lvanclub_int_build_20150731_170557.tar.gz   echo   exit 0} # check the app_env variable valuecase ${app_env} in   dev)       echo "ECHO: don't support dev environment present"       help       exit 1       ;;   int)       user=apache       group=apache       ;;   sandbox)       user=apache       group=apache       ;;   live)       user=php-fpm       group=php-fpm       ;;   *)       echo "ERROR: invalid app_env value, should be dev, int, sandbox orlive!"       help       exit 1       ;;esac # check the build_file_path variable valueif [ -z ${build_file_path} ]then   echo "ERROR: please specify the build file path"   help   exit 1elif [ ! -f ${build_file_path} ]then   echo "ERROR: specified build file '${build_file_path}' is notfound"   help   exit 1fi # reference: linux shell 字符串操作（长度，查找，替换）详解 - http://www.cnblogs.com/chengmo/archive/2010/10/02/1841355.html# only keep the build folder namebuild_file_name=${build_file_path##*/}build_name=${build_file_name%.tar.gz}# if current build folder exists, justremove itrm ${work_dir}/${build_name} -rvftar xzvf ${build_file_path}--directory=${work_dir}/ # make soft link for cpserver projectcd ${work_dir}/${build_name}/sdkserver/webln -s ../../cpserver cpserver # copy log filescd ${work_dir}# appstorecp${release_dir}/${app_env}/appstore/apps/api/var/logs ${work_dir}/${build_name}/appstore/apps/api/var/-rvf# appstore dashboardcp${release_dir}/${app_env}/appstore/apps/dashboard/var/logs${work_dir}/${build_name}/appstore/apps/dashboard/var/ -rvf# sdkservercp${release_dir}/${app_env}/sdkserver/protected/logs${work_dir}/${build_name}/sdkserver/protected/ -rvfcp${release_dir}/${app_env}/sdkserver/protected/runtime${work_dir}/${build_name}/sdkserver/protected/ -rvf# cpservercp ${release_dir}/${app_env}/cpserver/logs${work_dir}/${build_name}/cpserver/ -rvf # change file owners and permissionschown ${user}:${group}${work_dir}/${build_name} -Rchmod 775 ${work_dir}/${build_name} -R # make build as current releaserm ${release_dir}/${app_env} -vfln -s ${work_dir}/${build_name}${release_dir}/${app_env} # restart php-fpm serviceservice php-fpm restart

以上脚本内容较少，没有注释。下面进行解读   

采用这种方式的原因：阿里云平台，挂载磁盘被分配在/mnt目录下

实际目录：/mnt/var/www/htdocs

软连接目录：/var/www/htdocs

正如help所说  dev 环境   int环境   sandbox环境  live环境   四套环境的版本切换。live环境为线上正式环境。

我已将思路共享，希望大家能给出改良方案！

#2015-08-26      以下为每次代码上线的实施文档

#此文档为暂时文档，后期部署jenkins 更换

#1 检查tar.gz文件里面一级菜单内容

#2 回滚操作：

# 根据第三步，选择近期升级版本。

第一步：

把要升级的软件包，传送至服务器：hz-bf-01

代码存放位置：/mnt/word

第二布：

分发软件包到相应的服务器

sh /mnt/shell/fenfa.sh /mnt/word/lvanclub_live_build_20150826_111450.tar.gz /mnt/var/www/htdocs

第三步：

执行ansiable:

ansible -i ./hosts  web -m command -a "sh /mnt/var/www/htdocs/release.sh live /mnt/var/www/htdocs/lvanclub_live_build_20150827_153156.tar.gz"
