Gitlab_ansible_jenkins三剑客④jenkins安装图解及freestyle的简单使用

java环境准备

# 安装jdk1.8

[root@node02 ~]# rpm -ivh jdk-8u181-linux-x64.rpm

vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_181-amd64

export PATH=$JAVA_HOME/bin:$PATH

# 验证是否安装成功

[root@node02 ~]# java -version

java version "1.8.0_181"

Java(TM) SE Runtime Environment (build 1.8.0_181-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

方法1：安装jar包形式的jenkins(不推荐)

jenkins相关的yum环境准备

[root@node02 ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo

export http_proxy=http://10.11.0.148:808

export https_proxy=http://10.11.0.148:808

export ftp_proxy=http://10.11.0.148:808

[root@node02 ~]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

# 下载jenkins并安装

https://prodjenkinsreleases.blob.core.windows.net/redhat-stable/jenkins-2.121.1-1.1.noarch.rpm

# jenkins的参数配置

修改jenkins的启动用户(不推荐)

# 添加deploy用户，将deploy用户设置为jenkins的启动用户

useradd deploy

[root@node02 ~]# vim /etc/sysconfig/jenkins

JENKINS_USER="deploy"

JENKINS_PORT="8080"

[root@node02 ~]# chown -R deploy.deploy /var/lib/jenkins/

[root@node02 ~]# chown -R deploy.deploy /var/log/jenkins/

[root@node5 ~]# lsof -i:8080

COMMAND   PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

java    83897 jenkins  162u  IPv6  91128      0t0  TCP *:webcache (LISTEN)

方法2：通过tomcat的方法安装jenkins(推荐)

下载tomcat8.5

https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.39/bin/apache-tomcat-8.5.39.zip

下载jenkins的war包

https://mirrors.tuna.tsinghua.edu.cn/jenkins/war/2.168/jenkins.war

# 添加deploy 作为jenkins的运行用户

[root@node5 jenkins]# useradd deploy

[root@node5 jenkins]# cd /usr/local/apache-tomcat-8.5.39/bin/

[root@node5 local]# chown -R deploy.deploy /usr/local/apache-tomcat-8.5.39/

[root@node5 local]# su - deploy

[deploy@node5 ~]$ pwd

/home/deploy

[deploy@node5 ~]$ cd /usr/local/apache-tomcat-8.5.39/bin/

[deploy@node5 bin]$ ./startup.sh

Using CATALINA_BASE:   /usr/local/apache-tomcat-8.5.39

Using CATALINA_HOME:   /usr/local/apache-tomcat-8.5.39

Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.5.39/temp

Using JRE_HOME:        /usr/java/jdk1.8.0_181-amd64

Using CLASSPATH:       /usr/local/apache-tomcat-8.5.39/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.39/bin/tomcat-juli.jar

Tomcat started.

[deploy@node5 bin]$ ps -ef|grep tomcat

deploy    53267      1 99 19:45 pts/0    00:00:04 /usr/java/jdk1.8.0_181-amd64/bin/java -Djava.util.logging.config.file=/usr/local/apache-tomcat-8.5.39/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dorg.apache.catalina.security.SecurityListener.UMASK=0027 -Dignore.endorsed.dirs= -classpath /usr/local/apache-tomcat-8.5.39/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.39/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/apache-tomcat-8.5.39 -Dcatalina.home=/usr/local/apache-tomcat-8.5.39 -Djava.io.tmpdir=/usr/local/apache-tomcat-8.5.39/temp org.apache.catalina.startup.Bootstrap start

deploy    53289  53228  0 19:45 pts/0    00:00:00 grep --color=auto tomcat

访问：tomcat 开始进行配置

[root@node5 ~]# cat /var/lib/jenkins/secrets/initialAdminPassword

安装推荐的插件

账号密码Admin和admin

配置邮箱

添加凭证

点击全局凭据

添加凭据

添加root凭据

创建一个freestyle的项目

编写描述信息

选择参数

输入dev和prod两个参数选项

添加文本参数

源代码管理

 复制gitlab代码仓库的地址

报错的处理：

Failed to connect to repository : Command "git ls-remote -h https://gitlab.example.com/root/test-repo.git HEAD" returned status code 128:
stdout: 
stderr: fatal: unable to access 'https://gitlab.example.com/root/test-repo.git/': Peer's certificate issuer has been marked as not trusted by the user.

SSL certificate problem: unable to get local issuer certificate

解决办法：

在jenkins服务器中安装git

Yum install –y git

并执行以下命令：

[root@node5 logs]# git config --global http.sslVerify false

构建build配置

选择执行shell

执行脚本：

#!/bin/sh

export PATH="/bin/:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"

# print env variable

echo "[INFO] print env variable"

echo "current deployment environment is $deploy_env" >> test.properties

echo "the build is $version" >> test.properties

echo "[INFO] done..."

# check test properties

echo "[INFO] check test properties"

if [ -s test.properties ]

then

  cat test.properties

  echo "[INFO] done"

else

  echo "test.properties is empty"

fi

echo "[INFO] build finished..."

执行任务构建

控制台输出
