2.2 创建Tomcat启动参数setenv.sh文件
catalina.sh在执行的时候会调用同级路径下的setenv.sh来设置额外的环境变量，因此需要在/usr/local /tomcat/bin路径下创建setenv.sh文件。
执行脚本：
[zm@zm-centos7 ~]$ su # 切换至root用户
密码：
[root@zm-centos7 zm]# vim /usr/local/tomcat/bin/setenv.sh # 创建setenv.sh脚本
[root@zm-centos7 zm]# cat /usr/local/tomcat/bin/setenv.sh # 查看setenv.sh脚本内容
vi /home/appserver/tomcat3/bin/setenv.sh
export CATALINA_HOME=/home/appserver/tomcat3/
export CATALINA_BASE=/home/appserver/tomcat3/
#设置Tomcat的PID文件
CATALINA_PID="$CATALINA_BASE/tomcat3.pid"
#添加JVM选项
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"
chmod +x setenv.sh
#bak
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=/usr/local/tomcat
#设置Tomcat的PID文件
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
#添加JVM选项
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"
2.3 编写tomcat.service文件
在/usr/lib/systemd/system路径下添加tomcat.service文件。
注意：文件中目录路径必须是绝对路径
执行脚本：
[root@zm-centos7 zm]# vim /usr/lib/systemd/system/tomcat3.service #创建tomcat.service服务脚本
[root@zm-centos7 zm]# cat /usr/lib/systemd/system/tomcat3.service #查看tomcat.service服务脚本
[Unit]

After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]

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]配置服务的pid，服务的启动，停止，重启
[install]配置了使用用户

ExecStop=/opt/tomcat/latest/bin/shutdown.sh
[Install]
WantedBy=multi-user.target
通知systemd我们创建了一个新的单元文件并通过执行以下命令来启动Tomcat服务：
sudo systemctl daemon-reload
sudo systemctl start tomcat
您可以使用以下命令检查服务状态：
sudo systemctl status tomcat
2.4 测试Tomcat.service服务
执行脚本：
[root@zm-centos7 zm]# systemctl enable tomcat3 # 设置开机自启动
Created symlink from /etc/systemd/system/multi-user.target.wants/tomcat.service to /usr/lib/systemd/system/tomcat.service. # 自动创建软连接
[root@zm-centos7 zm]# systemctl start tomcat3 # 启动tomcat服务
[root@zm-centos7 zm]# systemctl status tomcat3 # 查看tomcat服务状态
● tomcat.service - Tomcat8
=使用tomcat.service=
systemctl enable tomcat.service
systemctl start tomcat.service
systemctl stop tomcat.service
systemctl restart tomcat.service
=trouble=
[root@oracle-zimg-etc ~]# /home/appserver/tomcat3/bin/shutdown.sh
Using CATALINA_BASE: /home/appserver/tomcat3/
Using CATALINA_HOME: /home/appserver/tomcat3/
Using CATALINA_TMPDIR: /home/appserver/tomcat3//temp
Using JRE_HOME: /usr/java/jdk1.7.0_75
Using CLASSPATH: /home/appserver/tomcat3//bin/bootstrap.jar:/home/appserver/tomcat3//bin/tomcat-juli.jar
Using CATALINA_PID: /home/appserver/tomcat3//tomcat3.pid
$CATALINA_PID was set but the specified file does not exist. Is Tomcat running? Stop aborted.
程序在的 但是停止时会这样 也就是 自带的停止脚本会无效 哦 第一次就会这样 第一次强制停止 以后的 以后的脚本
