tomcat配置systemctl管理服务和shell脚本文件管理

确保有java环境和tomcat环境

1.配置service方式管理

（1）配置/etc/profile

路径使用你的jdk和tomcat的目录路径

（2）配置服务文件tomcat.service

根据自己的实际目录进行配置，JAVA_HOME=和CATALINA_HOME=两个的配置和上面/etc/profile保持一致

此处是配置的tomcat用户进行启动（可以更改为已有用户，需考虑权限问题），那么还需要将tomcat的相关所有文件属主和属组改为tomcat

 （3）重载配置，测试tomcat服务

2.通过shell脚本方式管理

（1） 编写shell脚本

（2）运行测试

确保有java环境和tomcat环境

[root@localhost java]# java -version
java version "1.8.0_371"
Java(TM) SE Runtime Environment (build 1.8.0_371-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.371-b11, mixed mode)

[root@localhost ~]# /usr/local/tomcat/apache-tomcat-8.5.70/bin/version.sh 
Using CATALINA_BASE:   /usr/local/tomcat/apache-tomcat-8.5.70
Using CATALINA_HOME:   /usr/local/tomcat/apache-tomcat-8.5.70
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.70/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_371
Using CLASSPATH:       /usr/local/tomcat/apache-tomcat-8.5.70/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.70/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Server version: Apache Tomcat/8.5.70
Server built:   Aug 9 2021 16:17:14 UTC
Server number:  8.5.70.0
OS Name:        Linux
OS Version:     3.10.0-1160.el7.x86_64
Architecture:   amd64
JVM Version:    1.8.0_371-b11
JVM Vendor:     Oracle Corporation

1.配置service方式管理

（1）配置/etc/profile

路径使用你的jdk和tomcat的目录路径

[root@localhost ~]# tail -4 /etc/profile 
export JAVA_HOME=/usr/java/jdk1.8.0_371
export PATH=$JAVA_HOME/bin:$PATH
export CATALINA_HOME=/usr/local/tomcat/apache-tomcat-8.5.70
export TOMCAT_HOME=/usr/local/tomcat/apache-tomcat-8.5.70
[root@localhost ~]# source /etc/profile

（2）配置服务文件tomcat.service

根据自己的实际目录进行配置，JAVA_HOME=和CATALINA_HOME=两个的配置和上面/etc/profile保持一致

[root@localhost system]# pwd
/usr/lib/systemd/system
[root@localhost system]# vim tomcat.service 
# Systemd unit file for default tomcat
# 
# To create clones of this service:
# DO NOTHING, use [email protected] instead.

[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target

[Service]
Type=forking
Environment=JAVA_HOME=/usr/java/jdk1.8.0_371
Environment=CATALINA_HOME=/usr/local/tomcat/apache-tomcat-8.5.70
ExecStart=/usr/local/tomcat/apache-tomcat-8.5.70/bin/startup.sh
ExecStop=/usr/local/tomcat/apache-tomcat-8.5.70/bin/shutdown.sh
ExecReload=/bin/kill -s HUP $MAINPID
SuccessExitStatus=143
User=tomcat
Group=tomcat
PrivateTmp=true

[Install]
WantedBy=multi-user.target

此处是配置的tomcat用户进行启动（可以更改为已有用户，需考虑权限问题），那么还需要将tomcat的相关所有文件属主和属组改为tomcat

[root@localhost ~]# chown -R tomcat:tomcat /usr/local/tomcat/

 （3）重载配置，测试tomcat服务

[root@localhost system]# systemctl daemon-reload 
[root@localhost system]# systemctl stop tomcat
[root@localhost system]# systemctl status tomcat
● tomcat.service - Apache Tomcat Web Application Container
   Loaded: loaded (/usr/lib/systemd/system/tomcat.service; disabled; vendor preset: disabled)

2.通过shell脚本方式管理

（1） 编写shell脚本

[root@localhost tomcat]# vim tomcatmg.sh
#!/bin/bash
tomcat_home=/tomcat/apache-tomcat-8.5.70
tomcatdown=$tomcat_home/bin/shutdown.sh
tomcatstart=$tomcat_home/bin/startup.sh
pidtomcat=`ps -ef | grep $tomcat_home | grep -v "grep" | awk '{print $2}'`
case $1 in
start)
$tomcatstart
echo "tomcat启动"
;;
stop)
$tomcatdown
echo "tomcat关闭"
kill -9 $pidtomcat
;;
restart)
$tomcatdown
kill -9 $pidtomcat
sleep 2
$tomcatstart
echo "tomcat重启"
;;
esac

（2）运行测试 

[root@localhost tomcat]# vim tomcatmg,sh 

[root@localhost tomcat]# bash tomcatmg.sh stop
