1.java官網(wǎng)下載jdk
2.使用sftp上傳壓縮包到linux
cd /usr/local/
mkdir java
cd java
put C:\Users\user\Downloads\jdk-8u171-linux-x64.tar.gz
3.解壓縮
tar -xzvf jdk-8u171-linux-x64.tar.gz

export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
5.刷新環(huán)境變量生效
source /etc/profile
6.驗證
java -version

1.安裝maven，官網(wǎng)下載maven壓縮包
2.使用sftp上傳壓縮包到linux
cd /usr/local/
mkdir maven
cd maven
put C:\Users\user\Downloads\apache-maven-3.5.4-bin.tar.gz
3.解壓縮
tar -xzvf apache-maven-3.5.4-bin.tar.gz
4.設置環(huán)境變量
vi /etc/profile
export MAVEN_HOME=/usr/local/maven/apache-maven-3.5.4
export MAVEN_HOME
export PATH=$PATH:$MAVEN_HOME/bin
5.刷新環(huán)境變量生效
source /etc/profile
6.驗證
mvn -version

安裝git 略

1.注冊用戶名，生成公鑰私鑰
git config --global user.name "junjunye.aliyun"
git config --global user.email "519291499@qq.com"
ssh-keygen -t rsa -C “junjun.ye@aliyun.com”

2.查看公鑰把公鑰提交到碼云
cat ~/.ssh/id_rsa.pub

3.查看私鑰，準備提供給jenkins
cat ~/.ssh/id_rsa

4.驗證git是否能從代碼庫拉取代碼

git clone 。。。。。。

安裝tomcat
1.tomcat官網(wǎng)下載tomcat
2.使用sftp上傳壓縮包到linux
cd /usr/local/
mkdir tomcat
cd tomcat
put C:\Users\user\Downloads\apache-tomcat-8.5.31.tar.gz
3.解壓縮
tar -xzvf apache-tomcat-8.5.31.tar.gz
4.更改tomcat端口號為9999
vi server.xml
把8080端口號改為9999

5.tomcat user里添加用戶，用于jenkins里的代碼啟動熱部署
vi tomcat-users.xml

<role rolename="admin" />
<role rolename="admin-gui" />
<role rolename="manager" />
<role rolename="manager-script" />
<role rolename="manager-gui" />
<user username="admin" password="123456" roles="admin,manager,manager-script,manager-gui,admin-gui"/>
6.啟動tomcat，注意，一定要啟動，否則jenkins將無法熱部署
bin目錄下
sh startup.sh
7.驗證tomcat是否啟動成功
ps -ef|grep tomcat

安裝jenkins
1.官網(wǎng)下載jenkins包

2.使用sftp上傳壓縮包到linux
cd /usr/local/
mkdir jenkins
cd jenkins
put C:\Users\user\Downloads\jenkins-2.128-1.1.noarch.rpm
3.安裝jenkins
rpm -ivh jenkins-2.128-1.1.noarch.rpm

4.指定jenkins java路徑并修改jenkins權限為root
vi /etc/init.d/jenkins
修改文件里面的新增如下紅字內(nèi)容

Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.

see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/bin/java
/usr/local/java/jdk1.8.0_171/bin/java
"
for candidate in $candidates
do
[ -x "$JENKINS_JAVA_CMD" ] && break
JENKINS_JAVA_CMD="$candidate"
done

vi /etc/sysconfig/jenkins
修改
JENKINS_USER="root"

5.啟動jenkins
sudo service jenkins start
6.驗證jenkins是否啟動
ps -ef|grep jenkins
7.網(wǎng)頁進入配置jenkins
初始化解鎖

cat /var/lib/jenkins/secrets/initialAdminPassword
