centos6 + jenkins + gitlab + springboot + tomcat一键部署

0

最近折腾了2天,终于完整得搭建了一套自动打包,自动部署得环境,里面坑很多,分享出来,攒点人品,让后来者避开这些坑。
部署机器:

  1. 192.168.0.94 (centos6),运行gitlab,jenkins
  2. 192.168.0.93 (centos6),运行tomcat

图简单得话,可以直接将防火墙关闭,否则就需要开放这些服务用到得端口。这里面gitlab使用13001,Jenkins使用13002.

打开配置文件

vim /etc/sysconfig/iptables

加入如下语句:

-A INPUT -p tcp -m state --state NEW -m tcp--dport 13001 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp--dport 13002 -j ACCEPT

保存(按Esc退出编辑)

:wq

重启防火墙,修改完成

service iptables restart

  1. 安装JDK(目前Jenkins支持jdk8到jdk11)
    讲jdk-8u11-linux-x64.tar.gz解压到/opt/java下面,/etc/profile文件添加好相关路径即可。

tar -zxvf jdk 将解压后得文件夹放在/usr/local下面

export JAVA_HOME=/usr/local/jdk1.8.0_11

export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$PATH:$JAVA_HOME/bin

source /etc/profile(让改动生效)

  1. Maven安装
    tar-zxvf apache-maven-3.5.0-bin.tar.gz

mv apache-maven-3.5.0/* /usr/local/maven/
vim /etc/profile
exportM2_HOME=/usr/local/maven

exportPATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$M2_HOME/bin:$PATH

source /etc/profile
配置仓库信息和镜像源,使用阿里云:

在/usr/local/maven/conf/settings.xml下面配置仓库信息:

<localRepository>/opt/maven/repo</localRepository>

<mirror>

 <id>alimaven</id>

 <mirrorOf>central</mirrorOf>

 <name>aliyun maven</name>

 <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

</mirror>

  1. gitlab安装

A. 安装依赖软件
yum -y install policycoreutils openssh-server openssh-clientspostfix
B. 获取rpm包并安装
wget https://mirrors.tuna.tsinghua...

rpm -ivh gitlab-ce-9.3.6-ce.0.el7.x86_64.rpm

C. 自定义端口和存放路径
vim /etc/gitlab/gitlab.rb
external_url 'http://192.168.0.94:13001'

git_data_dirs({ "default" => { "path" => "/var/opt/gitlab/git-data", 'gitaly_address' => 'unix:/var/opt/gitlab/gitaly/gitaly.socket' } })

git_data_dir "/oracle/gitlab"
增加一个 git_data_dir

D. 启动gitlab
gitlab-ctl reconfigure

gitlab-ctl restart

  1. 安装jenkins

root用户下:

下载依赖
wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat...
导入秘钥
sudo rpm --import https://pkg.jenkins.io/redhat...
安装jenkins
yum install jenkins
配置jenkins的端口以及修改用户为root:
[root@localhost ~]# vi /etc/sysconfig/jenkin

配置jenkins得java路径:
vim /etc/init.d/jenkins
找到 candidates,里面加入你本机的实际java路径

启动jenkins: service jenkins restart
日志位置:/var/log/jenkins/jenkins.log

一个注意得地方:
刚启动jenkins得时候,会提示你该jenkins处于离线状态,需要处理一下:

  1. 打开配置界面

http://localhost:13002/pluginManager/advanced

clipboard.png

  1. http://localhost:13002/restart
  2. 编写一个springboot得测试程序,改pom文件为编译成一个war包

package com.avictc.springlearn;

import com.alibaba.fastjson.JSONObject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
@RequestMapping("/test1")
public class SpringlearnApplication extends SpringBootServletInitializer {

@RequestMapping("/getJSon")
public JSONObject returnJson(){
    JSONObject o = new JSONObject();
    o.put("hello","yes");
    return o;
}

@RequestMapping("/getString")
public String returnJson2(){
    return "hello";
}


public static void main(String[] args) {
    SpringApplication.run(SpringlearnApplication.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(SpringlearnApplication.class);
}

}

  1. 开始配置jenkins,,系统管理--》全局工具配置

注意:git需要配置到bin目录下得git,其他JDK,Maven只需要配置到主目录即可。

系统管理-》系统设置,配置jenkins需要ssh到的服务器,比如192.168.0.93

clipboard.png

clipboard.png

需要首先在Jenkins所在的机器192.168.0.94
ssh-keygen -t rsa

clipboard.png

生成了私钥文件id_rsa,公钥文件id_rsa.pub
将公钥文件id_rsa.pub的内容追加到192.168.0.93中的/root/.ssh/authorized_keys中,这样,94就可以ssh到93这台机器了。

  1. 新建一个job,并进行配置:

clipboard.png 触发器暂时不考虑,手工点击构建即可

192.168.0.93上面的restartTomcat.sh文件内容:

!/bin/sh

export BUILD_ID=dontkillme
export JAVA_HOME=/opt/java/jdk1.8.0_11
PID=ps -ef |grep /opt/java/apache-tomcat-9.0.19/conf |grep -v grep | awk '{print $2}'
if [ ! "$PID" ];then
echo "tomcat not start"
else
echo "will kill tomcat process:$PID"
kill -9 $PID
fi
cd /opt/java/apache-tomcat-9.0.19/webapps
rm -rf springtest*
mv /opt/java/apache-tomcat-9.0.19/*.war /opt/java/apache-tomcat-9.0.19/webapps

cd /opt/java/apache-tomcat-9.0.19/bin/
nohup sh ./startup.sh
echo "tomcat start executes"
sleep 3s

注意:一定要export JAVA_HOME,否则Tomcat怎么都启动不了!!!

至此,可以放心的一键部署了,完成了所有步骤。
