Ubuntu 18.04安装apache
1.下载apache-tomcat7.0.532.解压文件到/usr/local/apache-tomcat目录，没有apache-tomcat目录则先新建该目录
3.由于tomcat安装依赖JAVA JDK，查看Linux系统是否配置有java环境
（1）用 java -version 命令查看当前jdk版本信息
java -versionhttps://s1.运维网.com/images/20190124/1548322292946537.png
（2）用rpm -qa | grep java 命令查询操作系统自身安装的java
rpm -qa | grep java

由此可见，我的Linux系统中没有安装过JAVA JDK，所以要先下载安装。
4.安装JAVA JDK
推荐一个安装配置博客：https://www.cnblogs.com/liugh/p/6623530.html
5.启动Tomcat
（1）进入tomcat执行目录
cd /usr/local/tomcat/tomcat7/bin （2）添加JAVA JDK环境变量，编辑setclasspath.sh
sume@ubuntu:/usr/local/apache-tomcat/apache-tomcat-7.0.53/bin$ sudo vim setclasspath.sh 在setclasspath.sh中，一定要在以下两段间添加环境变量，不然tomcat启动失败。
# -----------------------------------------------------------------------------
#Set JAVA_HOME or JRE_HOME if not already set, ensure any provided settings
#are valid and consistent with the selected start-up options and set up the
#endorsed directory.
# -----------------------------------------------------------------------------
#my append
export JAVA_HOME=/usr/local/jdk8/jdk1.8.0_201
export JRE_HOME=/usr/local/jdk8/jdk1.8.0_201/jre # Make sure prerequisite environment variables are set
（3）查看tomcat的运行状态
ps -ef |grep tomcathttps://s1.运维网.com/images/20190124/1548326227741729.png
（4）启动tomcat
sudo ./startup.shhttps://s1.运维网.com/images/20190124/1548326368210861.png
Tomcat的端口号是8080，在保证网络畅通的情况下，在WINDOWS浏览器输入地址，能看到Tomcat网页就是配置成功了
