Jenkins+Git+Maven+Tomcat详细安装步骤

jenkins安装

jenkins的war包安装

以下war包的安装是直接使用war包内嵌的页面访问，也可以将war包放到tomcat的webapps下通过tomcat访问，在下面的tomcat步骤有补充说明

1、首先下载jenkins war包到相应的要安装的目录下（http://mirrors.jenkins.io/war-stable/latest/jenkins.war）

2、安装jdk，这里直接使用yum安装的，/etc/profile 下添加java的环境变量，source /etc/profile 重启， jave -version查看版本

2、java -jar jenkins.war 运行war包；可以使用nohup命令后台运行　nohup java -jar jenkins.war

3、http://http://ip:8080http://ip:8080 访问即可（想要修改端口的话启动命令后面直接加参数 java -jar jenkins.war --httpPort=8081）

4、稍等一会出来如下页面，cat 上面的路径获取密码

5、根据提示可选择推荐安装或自定义安装，这里建议先选择推荐，后期需要的插件可在里面设置。

tomcat安装

1、下载安装包

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.zip

2、解压并放到相应目录

unzip apache-tomcat-9.0.24.zip  #解压包
mv apache-tomcat-9.0.24 /usr/local/tomcat  #重命名为tomcat

3、Tomcat设置变量

方法一：在/etc/profile中添加

方法二：定义在tomcat自带的启动和关闭脚本里/usr/local/tomcat/bin/startup.sh和shutdown.sh

　　在2个脚本中开头添加下面的内容：注意jdk是提前安装好的，并且注意自己实际的jdk的路径（下面有补充的jdk安装说明）

export JAVA_HOME=/usr/local/java/jre-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar
export PATH=$PATH:/usr/local/jjava/jre-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/bin:/usr/local/tomcat/bin

4、启动tomcat

环境变量设置好后直接可通过脚本启动

[root@localhost bin]# sh startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/java/jre-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

查看端口是否启动（默认端口8080）

[root@localhost bin]# netstat -antlp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

通过ip:8080访问

5、端口设置/usr/local/tomcat/conf/server.xml（jenkins的默认端口也是8080）

补充：上面在安装jenkins war包时说过，可以将war包直接放在tomcat的webapps下，通过直接访问tomcat来访问jenkins

　　在/usr/local/tomcat/webapps下wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war（这里我把tomcat端口设置成了8090，也可以不用）

关于jdk说明

上述使用的jdk都是yum安装，所以注意自己的安装路径

wget http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.rpm

#安装包安装可将包放在/usr/local下将包重名为jdk在/etc/profile中加入如下

export JAVA_HOME=/usr/local/jdk 
export JAVA_BIN=/usr/local/jdk/bin                  
export PATH=$PATH:$JAVA_HOME/bin                  
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar                  
export JAVA_HOME JAVA_BIN PATH CLASSPATH

#yum安装默认的路径是/usr/lib/jvm中

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64
PATH=$PATH:$JAVA_HOME/bin  
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar  
export JAVA_HOME  CLASSPATH  PATH

安装github

安装git

yum -y install git

初始化github

#下列的用户名和邮箱不需要一定存在，只要写就可以
[root@localhost webapps]# git config --global user.name "yang"
[root@localhost webapps]# git config --global user.email "yang@abc.com"

查看git

[root@localhost webapps]# git version
git version 1.8.3.1

生成密钥

[root@localhost webapps]# ssh-keygen -t rsa -C "yang@abc.com"   #出现提示敲回车即可

#密钥路径，第一个是私钥，第二个是公钥
[root@localhost webapps]# cd ~/.ssh/
[root@localhost .ssh]# ls
id_rsa  id_rsa.pub

将公钥上传到github中，vim id_rsa.pub 将内容添加到图中位置

验证linux与github是否建立连接，输入下列命令

[root@localhost .ssh]# ssh git@github.com
The authenticity of host 'github.com (52.74.223.119)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.

安装maven

下载maven安装包到本地目录/usr/local

wget  http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

解压安装包并命名为maven

tar -zvxf  apache-maven-3.3.9-bin.tar.gz
mv apache-maven-3.3.9 maven

修改环境变量/etc/profile

export MAVEN_HOME=/usr/local/maven

export  PATH=${MAVEN_HOME}/bin:$PATH

source /etc/profile 并检验安装

[root@localhost local]# mvn -version
