一.系统版本及环境

1.CentOS 7.5  64bit    查看系统版本及位数命令

2.jdk 1.8 已安装配置   JDK1.8安装

二.Tomcat 8.5 安装

1.下载地址

http://tomcat.apache.org/

下载完后用ftp工具上传到linux服务器或者直接复制进linux虚拟机（图形界面，安装了VMware-tool） 

2.解压以及新建文件

tar -zxvf apache-tomcat-8.5.32.tar.gz

复制或者移动到 /usr/local/tomcat

先创建 /usr/local/tomcat

mkdir /usr/local/tomcat

移动

mv apache-tomcat-8.5.32 /usr/local/tomcat/

3.配置tomcat server.xml

server.xml可以配置端口，编码以及配置项目等等，配置端口把默认的8080，修改成80

vim /usr/local/tomcat/apache-tomcat-8.5.32/conf/server.xml

4.配置防火墙，开放80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent firewall-cmd --reload

5.启动tomcat（启动bin目录下的startup.sh）

/usr/local/tomcat/apache-tomcat-8.5.32/bin/startup.sh

Using CATALINA_BASE:   /usr/local/tomcat/apache-tomcat-8.5.32Using CATALINA_HOME:   /usr/local/tomcat/apache-tomcat-8.5.32Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.32/tempUsing JRE_HOME:        /usr/local/java/jdk1.8.0_181Using CLASSPATH:       /usr/local/tomcat/apache-tomcat-8.5.32/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.32/bin/tomcat-juli.jarTomcat started.

以上内容说明启动成功

关闭：/usr/local/tomcat/apache-tomcat-8.5.32/bin/shutdown.sh

6.浏览器测试

地址栏输入虚拟机ip地址：192.168.0.104     默认端口80

说明配置成功 

三.设置开机自启

1.编辑tomcat.service

vim /usr/lib/systemd/system/tomcat.service

编辑内容，保存 

[Unit] Description=Apache Tomcat Web Application Container After=syslog.target network.target remote-fs.target nss-lookup.target [Service] Type=forking Environment='JAVA_HOME=/usr/local/java/jdk1.8.0_181/' Environment='CATALINA_PID=/usr/local/tomcat/apache-tomcat-8.5.32/tomcat.pid' Environment='CATALINA_HOME=/usr/local/tomcat/apache-tomcat-8.5.32/' Environment='CATALINA_BASE=/usr/local/tomcat/apache-tomcat-8.5.32/' Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC' PIDFile=/usr/local/tomcat/apache-tomcat-8.5.32/tomcat.pid ExecStart=/usr/local/tomcat/apache-tomcat-8.5.32/bin/startup.sh ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target

[unit]配置了服务的描述，规定了在network启动之后执行。

[service]配置了环境变量，JAVA_HOME,服务的pid，服务的启动，停止，重启,内存参数。

[install]配置了使用用户。

当需要启动多个tomcat时，复制多个tomcat安装文件在/usr/local/tomcat/下如/tomcat/tomcat2，并配置多个tomcat.service 如tomcat2.service，tomcat3.service 在配置中修改对应的路径即可

2.设置开机自启

systemctl enable tomcat.service

3.启动tomcat

systemctl start tomcat.service
