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
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-8.5.32
Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-8.5.32
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.32/temp
Using JRE_HOME: /usr/local/java/jdk1.8.0_181
Using CLASSPATH: /usr/local/tomcat/apache-tomcat-8.5.32/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.32/bin/tomcat-juli.jar
Tomcat 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
