TOMCAT自启动 {tabs}{tabs-pane label="方式一"}systemctl方式1.找到JDK位置（后面的配置需用到）对于已经安装JDK，我们需要找出JDK的具体位置，可以参考以下命令root@ixjkj-standard-pc-i440fx-piix-1996-1:/usr/local/tomcat-11/apache-tomcat-11.0.0-M19/bin# which java /usr/local/jdk-17/jdk-17.0.11//bin/java root@ixjkj-standard-pc-i440fx-piix-1996-1:/usr/local/tomcat-11/apache-tomcat-11.0.0-M19/bin# whereis java java: /usr/bin/java /usr/share/java /usr/local/jdk-17/jdk-17.0.11/bin/java /usr/local/jdk1.8/bin/java root@ixjkj-standard-pc-i440fx-piix-1996-1:/usr/local/tomcat-11/apache-tomcat-11.0.0-M19/bin#find / -name java根据以上显示可知JDK的安装目录为：/usr/local/jdk-17/jdk-17.0.11Tomcat目录为：/usr/local/tomcat-11/apache-tomcat-11.0.0-M192.tomcat配置pid找到并编辑 tomcat/bin/catalina.sh# Copy CATALINA_BASE from CATALINA_HOME if not already set [ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME" # 设置pid。一定要加在CATALINA_BASE定义后面，要不然pid会生成到/下面 CATALINA_PID="$CATALINA_BASE/tomcat.pid"3.新建tomcat.service文件【非常重要：前提是完成第2步】nano /lib/systemd/system/tomcat.servicenano /etc/systemd/system/tomcat.service[Unit] Description=Apache Tomcat After=syslog.target network.target remote-fs.target nss-lookup.target [Service] Type=forking Environment="JAVA_HOME=/usr/local/jdk-17/jdk-17.0.11" PIDFile=/usr/local/tomcat-11/apache-tomcat-11.0.0-M19/tomcat.pid ExecStart=/usr/local/tomcat-11/apache-tomcat-11.0.0-M19/bin/startup.sh ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true User=root Group=root [Install] WantedBy=multi-user.target [Unit] 表示这是基础信息Description 是描述After 是在那个服务后面启动，一般是网络服务启动后启动[Service] 表示这里是服务信息Type 是服务类型PIDFile 是服务的pid文件路径， 开启后，必须在tomcat的bin/catalina.sh中加入CATALINA_PID参数ExecStart 是启动服务的命令ExecReload 是重启服务的命令ExecStop 是停止服务的指令[Install] 表示这是是安装相关信息WantedBy 是以哪种方式启动：multi-user.target表明当系统以多用户方式（默认的运行级别）启动时，这个服务需要被自动运行。若是中间再次修改tomcat.service文件后需要执行下面命令使其生效：systemctl daemon-reload4.启动成功。若是第2步没有完成直接进入第3步后，启动服务会出现一个错误5.设置开机自启#设置开机自启动 systemctl enable tomcat.service #停止开机自启动 systemctl disable tomcat.service #启动Tomcat服务 systemctl start tomcat.service #查看服务当前状态 systemctl status tomcat.service #重新启动服务 systemctl restart tomcat.service #查看所有已启动的服务 systemctl list-units --type=service查询TOMCAT进程（或者干掉进程）查询tomcat 进程ps -ef | grep tomcatkill -9 进程ID（备注：根据实际情况替换值）kill -9 856{/tabs-pane}{tabs-pane label="方式二"}/etc/init.d 方式（待验证）找到java、tomcat安装路径find / -name java复制tomcat/bin目录下的catalina.sh 到/etc/init.d目录下cp /usr/local/tomcat-11/apache-tomcat-11.0.0-M19/bin/catalina.sh /etc/init.d/tomcat将/etc/init.d/catalina.sh重命名为tomcatmv /etc/init.d/catalina.sh tomcat编辑tomcat文件，在头部添加内容（注意java、tomcat路径）nano /etc/init.d/tomcat### BEGIN INIT INFO # Provides: tomcat # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Should-Start: $network $time # Should-Stop: $network $time # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start tomcat daemon at boot time # Description: Start tomcat daemon at boot time ### END INIT INFO JAVA_HOME=/usr/local/jdk-17/jdk-17.0.11 JRE_HOME=/usr/local/jdk-17/jdk-17.0.11 CATALINA_HOME=/usr/local/tomcat-11/apache-tomcat-11.0.0-M19 CATALINA_BASE=/usr/local/tomcat-11/apache-tomcat-11.0.0-M19修改tomcat权限chmod +x /etc/init.d/tomcat重新加载服务器配置systemctl daemon-reload启动服务service tomcat start添加到自启动服务update-rc.d tomcat defaults查看是否开机自启，目前是disablesystemctl is-enabled tomcat.service将Tomcat服务设置为开机自启systemctl enable tomcat.service 重启，使配置生效sudo reboot{lamp/}修改或创建/etc/rc.local文件#!/bin/bash # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. service tomcat start exit 0复制/etc/rc.local到/etc/rc0.d目录cp /etc/rc.local /etc/rc0.d给这两个文件添加可执行权限chmod +x /etc/rc.local chmod +x /etc/rc0.d/rc.local重启服务器，tomcat或者tomcat下部署的项目查看是否配置成功reboot{/tabs-pane}{/tabs}
