一、安装jdk

1. 下载 jdk-8u161-linux-x64.tar.gz  链接：https://pan.baidu.com/s/1i8aQodhxwyZqfdfb9yl3Ig 密码：aioy
2. 通过xftp 将 jdk-8u161-linux-x64.tar.gz 上传到/home文件夹下
3. 解压

   [root@localhost home]# tar -zxvf jdk-8u161-linux-x64.tar.gz

4. 将解压后的文件夹移动到 /usr/local/ 文件夹下

   [root@localhost home]# mv jdk1.8.0_161/ /usr/local/

5. 修改系统配置

   [root@localhost home]# cat /etc/profile

   找到 export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL 位置，在下面添加如下配置并保存
   
   export JAVA_HOME=/usr/local/jdk1.8.0_161
   export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 
   export PATH=$PATH:$JAVA_HOME/bin

6. 重新加载配置

   [root@localhost home]# source /etc/profile

7. 测试Jdk 是否安装成功

   [root@localhost home]# java -version
   
   java version "1.8.0_161"
   Java(TM) SE Runtime Environment (build 1.8.0_161-b12)

4. 移动

   [root@localhost home]# mv apache-tomcat-8.5.29 /usr/local/tomcat-8.5.29

5. 创建 tomcat.service并保存
   

   [root@localhost home]# vi /usr/lib/systemd/system/tomcat.service
   

   [Unit]

   ExecStop=/bin/kill -s QUIT $MAINPID 
   PrivateTmp=true
   
   [Install] 
   WantedBy=multi-user.target

6. 启动tomcat服务
