自动化部署--shell脚本--1
传统部署方式
1、纯手工scp
2、纯手工登录git pull 、svn update
3、纯手工xftp往上拉
4、开发给打一个压缩包,rz上去。解压
传统部署缺点:
1、全程运维参与,占用大量时间
2、上线速度慢。
3、认为失误多。管理混乱
4、回滚慢,不及时
新项目上线,规划排在第一位
一般银行都不提供测试接口。比如一些电商公司测试的话,经常把商品调节成1分,只能特定账号能看到。
环境的规划
1、开发环境-开发者本地有自己的环境,然后运维需要设置的开发环境,放的是大家共用的服务。如开发数据库mysql,其它:redis、Memcached。
2、测试环境:功能测试环境和性能测试环境
3、预生产环境:一般可以用生产环境中的某个节点担任
4、生产环境:直接对用户提供服务的环境
预生产环境产生的原因:
1、数据库不一致:测试环境和生产环境数据库肯定不一样的。
2、使用生产环境的联调接口。例如,支付接口
部署:
1、代码放在哪里:svn,git
2、获取什么版本代码?
svn+git直接拉去某个分支
svn:指定版本号
git:指定tag
3、差异解决:
(1)、各个节点直接差异:
(2)、代码仓库和实际的差异。配置文件是否在代码仓库中
(3)、配置文件未必一样:crontab.xml预生产节点
4、如何更新。java tomcat。需要重启。
5、测试。
6、串行和并行 分组部署
7如何执行。(1)shell执行。(2)web界面
关于差异文件:

根据上面的流程图,先把大体框架写出来
[root@linux-node1 ~]# mkdir /scripts -p [root@linux-node1 ~]# cd /scripts/ [root@linux-node1 scripts]# vim deploy.sh [root@linux-node1 scripts]# chmod +x deploy.sh [root@linux-node1 scripts]# ./deploy.sh Usage: ./deploy.sh [ deploy | rollback ] [root@linux-node1 scripts]# cat deploy.sh #!/bin/bash #Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/deploy" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" usage(){ echo $"Usage: $0 [ deploy | rollback ]" } code_get(){ echo code_get } code_build(){ echo code_build } code_config(){ echo code_config } code_tar(){ echo code_tar } code_scp(){ echo code_scp } cluster_node_remove(){ echo cluster_node_remove } code_deploy(){ echo code_deploy } config_diff(){ echo config_diff } code_test(){ echo code_test } cluster_node_in(){ echo cluster_node_in } rollback(){ echo rollback } main(){ case $1 in deploy) code_get; code_build; code_config; code_tar; code_scp; cluster_node_remove; code_deploy; config_diff; code_test; cluster_node_in; ;; rollback) rollback; ;; *) usage; esac } main $1 [root@linux-node1 scripts]#
main(){ DEPLOY_METHOD=$1 case $DEPLOY_METHOD in deploy) code_get; code_build; code_config; code_tar; code_scp; cluster_node_remove; code_deploy; config_diff; code_test; cluster_node_in; ;;
继续完善脚本--添加日志和锁
1、凡是不记录日志的脚本就是刷流氓,执行到哪一步失败的啊?
2、脚本是否可以多个人一起执行?(最好不要多个人一起执行)不允许多人执行的话可以上锁
一般锁文件放下面目录下
[root@linux-node1 ~]# cd /var/run/lock/ [root@linux-node1 lock]# ls iscsi lockdev lvm ppp subsys [root@linux-node1 lock]#
我们可以单独添加个目录,给它用,因为权限问题,需要授权改变属组,我们使用tmp目录
主函数执行之前,应该先判断锁文件是否存在,执行的时候也应该生成这个lock文件
既然2个地方用到了它,是否可以把它制作成变量
新的脚本如下,主要添加了锁的功能
[root@linux-node1 scripts]# cat deploy.sh #!/bin/bash #Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/deploy" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock" usage(){ echo $"Usage: $0 [ deploy | rollback ]" } shell_lock(){ touch ${LOCK_FILE} } shell_unlock(){ rm -f ${LOCK_FILE} } code_get(){ echo code_get sleep 60; } code_build(){ echo code_build } code_config(){ echo code_config } code_tar(){ echo code_tar } code_scp(){ echo code_scp } cluster_node_remove(){ echo cluster_node_remove } code_deploy(){ echo code_deploy } config_diff(){ echo config_diff } code_test(){ echo code_test } cluster_node_in(){ echo cluster_node_in } rollback(){ echo rollback } main(){ if [ -f ${LOCK_FILE} ];then echo "Deploy is running" && exit; fi DEPLOY_METHOD=$1 case $DEPLOY_METHOD in deploy) shell_lock; code_get; code_build; code_config; code_tar; code_scp; cluster_node_remove; code_deploy; config_diff; code_test; cluster_node_in; shell_unlock; ;; rollback) shell_lock; rollback; shell_unlock; ;; *) usage; esac } main $1 [root@linux-node1 scripts]#
先执行下检查语法错误
[root@linux-node1 scripts]# ./deploy.sh deploy code_get code_build code_config code_tar code_scp cluster_node_remove code_deploy config_diff code_test cluster_node_in [root@linux-node1 scripts]# ./deploy.sh rollback rollback
加个sleep测试下锁的功能
给一个函数加下sleep 测试下执行中,另外的人是否可以执行这个脚本
code_get(){ echo code_get sleep 60; }
运行脚本
[root@linux-node1 scripts]# ./deploy.sh deploy code_get
[root@linux-node1 scripts]# ./deploy.sh deploy Deploy is running [root@linux-node1 scripts]# ./deploy.sh deploy Deploy is running [root@linux-node1 scripts]# ./deploy.sh rollback Deploy is running [root@linux-node1 scripts]#
增加日志功能
其实就是echo一行到日志文件中,每个函数写加echo 写到日志里,这样比较low
能不能写个日志函数,加时间戳。以后日志函数可以复制到其它脚本里
[www@linux-node1 scripts]$ date "+%Y-%m-%d" 2017-04-23 [www@linux-node1 scripts]$ date "+%H-%M-%S" 22-10-34 [www@linux-node1 scripts]$
#!/bin/bash # Date/Time Veriables CDATE=$(date "+%Y-%m-%d") CTIME=$(date "+%H-%M-%S") #Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/deploy" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock"
还不能这么写,不然以后的时间都是一样的
可以改成这样,它不会执行
#!/bin/bash # Date/Time Veriables CDATE='date "+%Y-%m-%d"' CTIME='date "+%H-%M-%S"' #Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/deploy" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock"
打包的时候,也用到时间戳命名了。还得用一个固定不变的时间用于打包
因为解压的时候,scp的时候用必须知道确定的包名字。
这里用到了2个时间,log-date是让它不执行的,cdate是让它执行的
#!/bin/bash # Date/Time Veriables LOG_DATE='date "+%Y-%m-%d"' LOG_TIME='date "+%H-%M-%S"' CDATE=$(date "+%Y-%m-%d") CTIME=$(date "+%H-%M-%S") #Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/deploy" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar"
[root@linux-node1 ~]# LOG_DATE='date "+%Y-%m-%d"' [root@linux-node1 ~]# LOG_TIME='date "+%H-%M-%S"' [root@linux-node1 ~]# echo $LOG_DATE date "+%Y-%m-%d" [root@linux-node1 ~]# echo $LOG_TIME date "+%H-%M-%S" [root@linux-node1 ~]#
[root@linux-node1 ~]# eval $LOG_TIME 22-21-05 [root@linux-node1 ~]# eval $LOG_DATE 2017-04-23 [root@linux-node1 ~]#
[root@linux-node1 ~]# eval $LOG_DATE && eval $LOG_TIME 2017-04-23 22-22-48 [root@linux-node1 ~]#
单独定义一个时间变量(这里用不到,但是可以实现)
[root@linux-node1 ~]# D_T='date "+%Y-%m-%d-%H-%M-%S"' [root@linux-node1 ~]# echo $D_T date "+%Y-%m-%d-%H-%M-%S" [root@linux-node1 ~]# eval $D_T 2017-04-26-19-33-01 [root@linux-node1 ~]#
usage(){ echo $"Usage: $0 [ deploy | rollback ]" } writelog(){ LOGINFO=$1 echo "${CDATE} ${CTIME}: ${SHELL_NAME} : ${LOGINFO}" >> ${SHELL_LOG} } shell_lock(){ touch ${LOCK_FILE} } shell_unlock(){ rm -f ${LOCK_FILE} }
shell_lock(){ touch ${LOCK_FILE} } shell_unlock(){ rm -f ${LOCK_FILE} } code_get(){ writelog code_get; } code_build(){ echo code_build }
shell_unlock(){ rm -f ${LOCK_FILE} } code_get(){ writelog "code_get"; } code_build(){ echo code_build }
[root@linux-node1 scripts]# mkdir /deploy/config -p [root@linux-node1 scripts]# mkdir /deploy/tmp -p [root@linux-node1 scripts]# mkdir /deploy/tar -p [root@linux-node1 scripts]# mkdir /deploy/code -p [root@linux-node1 scripts]# cd /deploy/ [root@linux-node1 deploy]# ll total 0 drwxr-xr-x 2 root root 6 Apr 23 22:37 code drwxr-xr-x 2 root root 6 Apr 23 22:37 config drwxr-xr-x 2 root root 6 Apr 23 22:37 tar drwxr-xr-x 2 root root 6 Apr 23 22:37 tmp [root@linux-node1 deploy]#
[root@linux-node1 deploy]# cd code/ [root@linux-node1 code]# mkdir web-demo -p [root@linux-node1 code]# cd .. [root@linux-node1 deploy]# tree . ├── code │ └── web-demo ├── config ├── tar └── tmp 5 directories, 0 files [root@linux-node1 deploy]#
修改脚本
#Shell Env SHELL_NAME="deploy.sh" SHELL_DIR="/home/www" SHELL_LOG="${SHELL_DIR}/${SHELL_NAME}.log" #Code Env CODE_DIR="/deploy/code/web-demo" CONFIG_DIR="/deploy/config" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock" usage(){ echo $"Usage: $0 [ deploy | rollback ]" }
code_get(){ writelog "code_get"; cd $CODE_DIR && git pull }
配置文件不要放这个目录下,这个目录只用来更新---git pull.你不好判断配置文件是仓库里面的,还是你专门下载下来的(最佳实践)
规划的时候,只让这里目录执行git pull
TMP_DIR="/deploy/tmp"
继续优化获取代码的函数
code_get(){ writelog "code_get"; cd $CODE_DIR && git pull cp -r ${CODE_DIR} ${TMP_DIR}/ }
配置操作的函数时候,觉得不合适,应该区分项目,标准化。比如web-demo可以理解为一个项目包名字
#Code Env CODE_DIR="/deploy/code/web-demo" CONFIG_DIR="/deploy/config/web-demo" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock"
目录新建
[root@linux-node1 scripts]# cd /deploy/ [root@linux-node1 deploy]# cd config/ [root@linux-node1 config]# mkdir web-demo [root@linux-node1 config]# cd .. [root@linux-node1 deploy]# tree . ├── code │ └── web-demo ├── config │ └── web-demo ├── tar └── tmp 6 directories, 0 files [root@linux-node1 deploy]#
[root@linux-node1 deploy]# cd config/ [root@linux-node1 config]# cd web-demo/ [root@linux-node1 web-demo]# vim config.ini [root@linux-node1 web-demo]# cat config.ini hehe [root@linux-node1 web-demo]#
#Code Env PRO_NAME="web-demo" CODE_DIR="/deploy/code/web-demo" CONFIG_DIR="/deploy/config/web-demo" TMP_DIR="/deploy/tmp" TAR_DIR="/deploy/tar" LOCK_FILE="/tmp/deploy.lock"
调整下脚本,优化code_config函数
code_get(){ writelog "code_get"; cd $CODE_DIR && git pull cp -r ${CODE_DIR} ${TMP_DIR}/ } code_build(){ echo code_build } code_config(){ echo code_config /bin/cp -r $CONFIG_DIR/* $TMP_DIR/$PRO_NAME }
code_get(){ writelog "code_get"; cd $CODE_DIR && git pull cp -r ${CODE_DIR} ${TMP_DIR}/ } code_build(){ echo code_build } code_config(){ echo code_config /bin/cp -r ${CONFIG_DIR}/* ${TMP_DIR}/"${PRO_NAME}" }
注意是/bin/cp ,这样原先有配置文件,这里可以直接替换了
如果开发把配置文件打包进去了。连接的是测试的库,假如你部署生产环境了,连接测试的库。出了问题,谁背黑锅
运维是最后一道防线。开发和测试没遇到。你背黑锅
code_config(){ echo code_config /bin/cp -r ${CONFIG_DIR}/* ${TMP_DIR}/"${PRO_NAME}" PKG_NAME="${PRO_NAME}"_"${API_VER}"-"${CDATE}-${CTIME}" }
继续优化
code_config(){ echo code_config /bin/cp -r ${CONFIG_DIR}/* ${TMP_DIR}/"${PRO_NAME}" PKG_NAME="${PRO_NAME}"_"${API_VER}"-"${CDATE}-${CTIME}" cd ${TMP_DIR} && mv ${PRO_NAME} ${PKG_NAME} }
添加版本号,先随便定义个版本
code_get(){ writelog "code_get"; cd $CODE_DIR && git pull cp -r ${CODE_DIR} ${TMP_DIR}/ API_VER="123" }
code_get(){ writelog "code_get"; cd $CODE_DIR && echo "git pull" cp -r ${CODE_DIR} ${TMP_DIR}/ API_VER="123" }

cluster_node_remove(){ writelog "cluster_node_remove" }
code_config(){ writelog "code_config" /bin/cp -r ${CONFIG_DIR}/* ${TMP_DIR}/"${PRO_NAME}" PKG_NAME="${PRO_NAME}"_"${API_VER}"_"${CDATE}-${CTIME}" cd ${TMP_DIR} && mv ${PRO_NAME} ${PKG_NAME} }
code_config(){ writelog "code_config" /bin/cp -r ${CONFIG_DIR}/base/* ${TMP_DIR}/"${PRO_NAME}" PKG_NAME="${PRO_NAME}"_"${API_VER}"_"${CDATE}-${CTIME}" cd ${TMP_DIR} && mv ${PRO_NAME} ${PKG_NAME} }
创建配置文件目录,base存放相同的配置,other存放差异配置
[www@linux-node1 scripts]$ cd /deploy/config/web-demo/ [www@linux-node1 web-demo]$ mkdir base [www@linux-node1 web-demo]$ mkdir other [www@linux-node1 web-demo]$ ll total 4 drwxrwxr-x 2 www www 6 Apr 23 23:38 base -rw-r--r-- 1 www www 5 Apr 23 22:46 config.ini drwxrwxr-x 2 www www 6 Apr 23 23:38 other [www@linux-node1 web-demo]$
调整下配置文件所在目录
[www@linux-node1 web-demo]$ mv config.ini base/ [www@linux-node1 web-demo]$ cd other/ [www@linux-node1 other]$ echo 192.168.58.12-config >>192.168.58.12.crontab.xml [www@linux-node1 other]$ ll total 4 -rw-rw-r-- 1 www www 21 Apr 23 23:39 192.168.58.12.crontab.xml [www@linux-node1 other]$
code_deploy(){ echo code_deploy cd /opt/webroot/ && tar xfz ${PKG_NAME}.tar.gz } config_diff(){ echo config_diff scp ${CONFIG_DIR}/other/192.168.58.12.crontab.xml 192.168.58.12:/opt/webroot/${PKG_NAME} }
[www@linux-node1 scripts]$ ./deploy.sh deploy git pull code_build code_scp web-demo_123_2017-04-23-23-43-48.tar.gz 100% 204 0.2KB/s 00:00 web-demo_123_2017-04-23-23-43-48.tar.gz 100% 204 0.2KB/s 00:00 code_deploy config_diff 192.168.58.12.crontab.xml 100% 21 0.0KB/s 00:00 code_test cluster_node_in [www@linux-node1 scripts]$
上面还有不足的地方,scp到目标服务器并解压,应该使用ssh远程执行、。上面脚本远程node2上解压是失败的
脚本再次改造下,把部署的函数和差异配置合并到一起
cluster_node_remove(){ writelog "cluster_node_remove" } code_deploy(){ echo code_deploy for node in $NODE_LIST;do ssh $node "cd /opt/webroot/ && tar xfz ${PKG_NAME}.tar.gz" done scp ${CONFIG_DIR}/other/192.168.58.12.crontab.xml 192.168.58.12:/opt/webroot/${PKG_NAME}/crontab.xml } code_test(){ echo code_test }
