#这个上次好像试了不太好 
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]
Description=Tomcat3
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/home/appserver/tomcat3/tomcat3.pid
ExecStart=/home/appserver/tomcat3/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]配置服务的pid，服务的启动，停止，重启 
[install]配置了使用用户

---------

#这个还没测试过 不过应该是可以 的 
[Unit]
Description=Tomcat 8.5 servlet container
After=network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment="JAVA_HOME=/usr/lib/jvm/default-java"
Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom"

Environment="CATALINA_BASE=/opt/tomcat/latest"
Environment="CATALINA_HOME=/opt/tomcat/latest"
Environment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

ExecStart=/opt/tomcat/latest/bin/startup.sh
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
