Jenkins+maven+gitlab+Tomcat自动部署版本更新及回滚

Jenkins+maven+gitlab+Tomcat自动部署版本更新及回滚

一、环境准备

系统	IP	主机名	运行服务
Centos7.3	192.168.171.131	Jenkins	Jenkins+gitlab+Maven
Centos7.3	192.168.171.134	Tomcat1	Tomcat
Centos7.3	192.168.171.135	Tomcat2	Tomcat

[root@jenkins ~]# rpm -qa | grep jdk copy-jdk-configs-1.2-1.el7.noarch java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64 java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64 java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64 java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64 #卸载下面的两个包 [root@jenkins ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64 [root@jenkins ~]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64 #部署我提供的jdk包 [root@jenkins ~]# tar zxf jdk-8u211-linux-x64.tar.gz -C /usr/local/ [root@jenkins ~]# vim /etc/profile export JAVA_HOME=/usr/local/jdk1.8.0_211 export JRE_HOME=/usr/local/jdk1.8.0_211/jre export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH [root@jenkins ~]# . /etc/profile [root@jenkins ~]# java -version java version "1.8.0_211" Java(TM) SE Runtime Environment (build 1.8.0_211-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

2、部署Maven服务

[root@jenkins ~]# tar zxf apache-maven-3.6.1-bin.tar.gz [root@jenkins ~]# mv apache-maven-3.6.1/ /usr/local/maven [root@jenkins ~]# vim /etc/profile export MAVEN_HOME=/usr/local/maven export PATH=$PATH:$MAVEN_HOME/bin [root@jenkins ~]# . /etc/profile [root@jenkins ~]# mvn -v #执行命令，只要出现下面内容就部署成功了（因为这是二进制的方式部署） Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00) Maven home: /usr/local/maven Java version: 1.8.0_211, vendor: Oracle Corporation, runtime: /usr/local/jdk1.8.0_211/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-514.el7.x86_64", arch: "amd64", family: "unix"

3、指定阿里云仓库

[root@jenkins ~]# vim /usr/local/maven/conf/settings.xml #在158行下写入以下内容 aliyun central aliyun maven https://maven.aliyun.com/nexus/content/groups/public/ #添加在该行上面

4、解决Jenkins无法启动问题至此，maven服务已经部署成功了，但是，这里还同时部署着Jenkins，Jenkins的启动是依赖之前的Java环境的，部署maven服务又重新配置了Java环境，所以，Jenkins当前无法正常启动，现在需要对Java命令做软连接

[root@jenkins ~]# ln -sf /usr/local/jdk1.8.0_211/bin/java /usr/bin/ [root@jenkins ~]# /etc/init.d/jenkins restart #重启Jenkins，确定可以启动成功 Restarting jenkins (via systemctl): [ OK ]

5、maven构建测试代码并上传至gitlab

[root@jenkins ~]# mvn archetype:generate -DgroupId=cn.test.testweb -DartifactId=testweb -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false [root@jenkins ~]# cd testweb/ [root@jenkins testweb]# vim src/main/webapp/index.jsp

Hello World! test1 web

#更改此行，以便区分不同版本 #删除本地gitlab库之前的文件，并提交到gitlab库 [root@jenkins test1]# rm -rf * [root@jenkins test1]# git commit -m "del" [root@jenkins test1]# git push origin master #将maven构建的项目复制到此目录下，并提交到gitlab远端库 [root@jenkins test1]# cd ~/testweb/ [root@jenkins testweb]# cp -r pom.xml src/ ~/test1/ [root@jenkins testweb]# cd ~/test1/ [root@jenkins test1]# git add * [root@jenkins test1]# git commit -m "test1 web" [root@jenkins test1]# git push origin master

6、配置Jenkins免密登录tomcat服务器

#由于需要Jenkins向Tomcat服务器复制代码及添加目录，所以需要配置免密登录 #默认在配置gitlab时，已经生成了当前用户的秘钥对，所以无需重新生成 #将公钥分别发送至两台tomcat服务器，自行输入“yes”确认，及tomcat的root密码 [root@jenkins test1]# ssh-copy-id root@192.168.171.135 [root@jenkins test1]# ssh-copy-id root@192.168.171.134

7、修改Jenkins的运行用户同样，也是为了方便Jenkins服务在运行过程中，拥有一些创建目录或写入文件的权限，我这里为了方便，直接改为root用户运行Jenkins，生产环境中，需要好好考虑权限问题

[root@jenkins test1]# sed -i 's/JENKINS_USER="jenkins"/JENKINS_USER="root"/g' /etc/sysconfig/jenkins [root@jenkins test1]# /etc/init.d/jenkins restart

##Deploy tomcat war_bak="/data/war/bak" tomcat_deploy="/usr/local/tomcat/webapps" #WAR_PATH="${WORKSPACE}/${MODULE_NAME}/target/*.war" WAR_PATH="${WORKSPACE}/target/*.war" #以下是定义测试服务器及线上服务器 test_host="192.168.171.134" #测试服务器，IP可以写多个，但是要注意格式 stag_host="192.168.171.135" #线上服务器，同样，IP可以写多个 port="8080" echo "构建环境:${deploy} 项目名称:${JOB_NAME} 构建时间:`date +%F` 本次上线版本:${GIT_COMMIT}" >> /var/log/${JOB_NAME}.log ### status deploy or rollback ##判断git是否为空，如果是为空进行提示 if [ "${git}" = "" ];then echo "请输入git版本 #############" exit 1 else ## 判断发布 or 回滚 if [ "${Status}" = "Deploy" ];then ### 判断是否为测试环境 if [ "${deploy}" = "test" ];then ### 构建主机 for i in ${test_host} do ssh ${i} "mkdir -p ${war_bak}/${JOB_NAME}/${git}" scp ${WAR_PATH} ${i}:${war_bak}/${JOB_NAME}/${git}/ROOT.war ssh ${i} rm -rf ${tomcat_deploy}/* ssh ${i} cp ${war_bak}/${JOB_NAME}/${git}/ROOT.war ${tomcat_deploy} ssh ${i} /etc/init.d/tomcat restart ### 判断tomcat是否正常 for in `seq 1 5` do tomcat_status=`curl -I ${i}:${port} -s|awk -F "[ ]" '{print $2}' |sed -n '1p'` if [[ "$tomcat_status" -ne 200 ]] || [[ "$tomcat_status" = "" ]];then echo -e "\033[5;34m 请稍等，服务启动中........ \033[0m" sleep 5 else echo -e "\033[5;34m 构建 ${i}环境发布正常,返回值[${tomcat_status}] \033[0m" break fi done if [[ "${tomcat_status}" -ne 200 ]] || [[ "${tomcat_status}" = "" ]];then if [[ "${tomcat_status}" = "" ]];then echo -e "\033[5;34m 构建 ${i}服务启动异常 \033[0m" exit 1 fi echo -e "\033[5;34m 构建 ${i}环境发布异常,返回值[${tomcat_status}] \033[0m" fi done echo -e "\033[5;34m 本次构建${test_host}主机,本次环境 ${deploy} \033[0m" ## 判断为预发布环境 elif [ "${deploy}" = "stag" ];then for i in "${stag_host}" do ssh ${i} mkdir -p ${war_bak}/${JOB_NAME}/${git} scp ${WAR_PATH} ${i}:${war_bak}/${JOB_NAME}/${git}/ROOT.war ssh ${i} rm -rf ${tomcat_deploy}/* ssh ${i} cp ${war_bak}/${JOB_NAME}/${git}/ROOT.war ${tomcat_deploy} ssh ${i} /etc/init.d/tomcat restart ### 判断tomcat是否正常 for in `seq 1 5` do tomcat_status=`curl -I ${i}:${port} -s|awk -F "[ ]" '{print $2}' |sed -n '1p'` if [[ "$tomcat_status" -ne 200 ]] || [[ "$tomcat_status" = "" ]];then echo -e "\033[5;34m 请稍等，服务启动中........ \033[0m" sleep 5 else echo -e "\033[5;34m 构建 ${i}环境发布正常,返回值[${tomcat_status}] \033[0m" break fi done if [[ "${tomcat_status}" -ne 200 ]] || [[ "${tomcat_status}" = "" ]];then if [[ "${tomcat_status}" = "" ]];then echo -e "\033[5;34m 构建 ${i}服务启动异常 \033[0m" exit 1 fi echo -e "\033[5;34m 构建 ${i}环境发布异常,返回值[${tomcat_status}] \033[0m" fi done echo -e "\033[5;34m 本次构建${test_host}主机,本次环境 ${deploy} \033[0m" fi ### 回滚操作 elif [[ "${Status}" = "RollBack" ]];then ### 判断回滚环境及主机 if [ "${deploy}" = "test" ];then for i in ${test_host} do ssh ${i} "[ -d ${war_bak}/${JOB_NAME}/${git} ]" if [ $? -ne '0' ];then echo -e "\033[5;34m git commit 回滚目录不存在，环境${deploy} 错误主机${i} \033[0m" exit 3 else echo -e "\033[5;34m 准备回滚操作 本次回滚环境${deploy} 回滚主机${i} \033[0m" sleep 3 fi ssh ${i} "mkdir -p ${war_bak}/${JOB_NAME}/${git}_${Status}_rollback/" ssh ${i} "cp -r ${tomcat_deploy}/* ${war_bak}/${JOB_NAME}/${git}_${Status}_rollback/" ssh ${i} "rm -rf ${tomcat_deploy}/*" ssh ${i} "cp -r ${war_bak}/${JOB_NAME}/${git}/*.war ${tomcat_deploy}/" ssh ${i} /etc/init.d/tomcat restart ### 判断tomcat是否正常 for in `seq 1 5` do tomcat_status=`curl -I ${i}:${port} -s|awk -F "[ ]" '{print $2}' |sed -n '1p'` if [[ "$tomcat_status" -ne 200 ]] || [[ "$tomcat_status" = "" ]];then echo -e "\033[5;34m 请稍等，服务启动中........ \033[0m" sleep 5 else echo -e "\033[5;34m 构建 ${i}环境发布正常,返回值[${tomcat_status}] \033[0m" break fi done if [[ "${tomcat_status}" -ne 200 ]] || [[ "${tomcat_status}" = "" ]];then if [[ "${tomcat_status}" = "" ]];then echo -e "\033[5;34m 构建 ${i}服务启动异常 \033[0m" exit 1 fi echo -e "\033[5;34m 构建 ${i}环境发布异常,返回值[${tomcat_status}] \033[0m" fi done elif [ "${deploy}" = "stag" ];then for i in ${stag_host} do ssh ${i} "[ -d ${war_bak}/${JOB_NAME}/${git} ]" if [ $? -ne '0' ];then echo -e "\033[5;34m git commit 回滚目录不存在，环境${deploy} 错误主机${i} \033[0m" exit 3 else echo -e "\033[5;34m 准备回滚操作 本次回滚环境${deploy} 回滚主机${i} \033[0m" sleep 3 fi ssh ${i} "mkdir -p ${war_bak}/${JOB_NAME}/${git}_${Status}_rollback/" ssh ${i} "cp -r ${tomcat_deploy}/* ${war_bak}/${JOB_NAME}/${git}_${Status}_rollback/" ssh ${i} "rm -rf ${tomcat_deploy}/*" ssh ${i} "cp -r ${war_bak}/${JOB_NAME}/${git}/*.war ${tomcat_deploy}/" ssh ${i} /etc/init.d/tomcat restart ### 判断tomcat是否正常 for in `seq 1 5` do tomcat_status=`curl -I ${i}:${port} -s|awk -F "[ ]" '{print $2}' |sed -n '1p'` if [[ "$tomcat_status" -ne 200 ]] || [[ "$tomcat_status" = "" ]];then echo -e "\033[5;34m 请稍等，服务启动中........ \033[0m" sleep 5 else echo -e "\033[5;34m 构建 ${i}环境发布正常,返回值[${tomcat_status}] \033[0m" break fi done if [[ "${tomcat_status}" -ne 200 ]] || [[ "${tomcat_status}" = "" ]];then if [[ "${tomcat_status}" = "" ]];then echo -e "\033[5;34m 构建 ${i}服务启动异常 \033[0m" exit 1 fi echo -e "\033[5;34m 构建 ${i}环境发布异常,返回值[${tomcat_status}] \033[0m" fi done ### 判断测试环境fi结束 fi fi #### fi是判断是否有git地址的结束 fi
