一、安装JDK

1.解压jdk的tar包

$ tar zxvf jdk-8u181-linux-x64.tar.gz -C /usr/local/

2.创建软连接

$ ln -sv /usr/local/jdk1.8.0_181/ /usr/local/java

3.添加环境变量

$ vim /etc/profile.d/java.shJAVA_HOME=/usr/local/javaCLASSPATH=$JAVA_HOME/lib/PATH=$PATH:$JAVA_HOME/binexport PATH JAVA_HOME CLASSPATH

4.执行环境变量文件

$ source /etc/profile.d/java.sh

5.检查JDK版本

$ java -versionjava 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)

二、安装Tomcat

1.解压tomcat

$ tar zxvf apache-tomcat-9.0.12.tar.gz -C /usr/local

2.创建软连接

$ ln -sv /usr/local/apache-tomcat-9.0.12/ /usr/local/tomcat

3.修改tomcat绑定的IP地址

$ cd /usr/local/tomcat$ vim ./conf/server.xml

4.启动tomcat

$ ./bin/catalina.sh start$ ss -tunl | grep -E "8080|8009|8005"tcp    LISTEN     0      1      ::ffff:127.0.0.1:8005                 :::*                  tcp    LISTEN     0      100      :::8009                 :::*                  tcp    LISTEN     0      100      ::ffff:192.168.101.100:8080                 :::*

5.curl测试

$ curl -I http://192.168.101.100:8080HTTP/1.1 200 Content-Type: text/html;charset=UTF-8Transfer-Encoding: chunkedDate: Mon, 17 Sep 2018 13:31:56 GMT

三、安装jenkins

1.关闭tomcat

$ ./bin/catalina.sh stop

2.备份webapps

$ cp -a -rf ./webapps ./webapps-bak

3.删除webapps目录种内容

$ rm -rf ./webapps/*

4.将jenkins.war放入webapps, 并修改为ROOT.war

$ mv webapps/jenkins.war webapps/ROOT.war

5.设置jenkins home

$ mkdir /usr/local/jenkins$ vim /etc/profile.d/jenkins.shexport CATALINA_OPTS="-DJENKINS_HOME=/usr/local/jenkins/ -Xmx512m"$ source /etc/profile.d/jenkins.sh$ echo $CATALINA_OPTS-DJENKINS_HOME=/usr/local/jenkins/ -Xmx512m

6.重新启动tomcat

$ ./bin/catalina.sh start

7.浏览器打开192.168.101.100:8080, 初始化jenkins

四、安装nginx

1.安装nginx

$ yum install -y nginx

2.制作TLS证书

3.修改nginx配置文件

upstream jenkins {    server 192.168.101.100:8080 fail_timeout=0;}server {    listen 443 ssl;    server_name rancher.leistudy.com;    ssl_certificate /etc/nginx/ssl/nginx.crt;    ssl_certificate_key /etc/nginx/ssl/nginx.key;    location / {            proxy_set_header Host $host:$server_port;            proxy_set_header X-Real-IP $remote_addr;            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;            proxy_set_header X-Forwarded-Proto $scheme;            proxy_redirect http:// https://;            proxy_pass      http://jenkins;            proxy_http_version 1.1;            proxy_request_buffering off;            #add_header 'X-SSH-Endpoint' 'rancher.leistudy.com:22' always;    }}

4.检查nginx配置并启动

$ nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful$ systemctl start nginx$ ss -tunl | grep "443"tcp    LISTEN     0      128       *:443                   *:*
