理论知识怱略，马上开始实战

一、首先准备好tomcat 启动、关闭、重启Shell脚本：

以下Shell脚本主要修改值

tomcatPath：tomcat目录

runUser:以哪个身份运行

此处测试的Shell脚本存放地址如下：

mkdir /usr/local/apache-tomcat-7.0./sbin/

vi /usr/local/apache-tomcat-7.0./sbin/tomcat-server
#复制tomcat-server的代码

chmod +x /usr/local/apache-tomcat-7.0.94/sbin/tomcat-server

#!/bin/bash

#Authtor : suk

#Date :

#Email : @qq.com

. /etc/init.d/functions

#Result Code

RETVAL=

#Tomcat Pid

TomcatPid=null

#Tomcat Home

tomcatPath=/usr/local/application/apache-tomcat-7.0.

runUser='tomcat'

getTomcatPid()

{

        TomcatPid=$(ps -ef | grep java |grep tomcat | grep -w $tomcatPath | grep -v 'grep ' | awk '{print $2}')

}

checkTocamtPid()

{

        getTomcatPid

        if [ -n "$TomcatPid" ];

        then

            #run

            RETVAL=

        else

            #no run

            RETVAL=

        fi

}

start()

{

        checkTocamtPid

        if [ $RETVAL -eq  ];

            then

                getTomcatPid

                action "Tomcat Already Running Pid:【$TomcatPid】" /bin/false

                exit $RETVAL

        else

                /bin/sudo su - $runUser $tomcatPath/bin/startup.sh

                getTomcatPid

                action "Start Tomcat Success Pid:【$TomcatPid】" /bin/true

        fi

}

restart()

{

        checkTocamtPid

        if [ $RETVAL -eq  ];

            then

                stop

                sleep

        fi

        start

}

stop()

{

        checkTocamtPid

        if [ $RETVAL -eq  ];

            then

                getTomcatPid

                /bin/kill - $TomcatPid

                action "Stop Tomcat PID:【$TomcatPid】" /bin/true

        else

                action "Tomcat Status No Running" /bin/false

        fi

}

#Check Tomcat Status

status()

{

        checkTocamtPid

        [ $RETVAL -eq   ] && echo "Tomcat is Running Pid:【$TomcatPid】" || echo "No Tomcat Running"

}

#Check Tomcat Start Logs

logs(){

        logsPath=$tomcatPath/logs/catalina.out

        if [ ! -f $logsPath ];then

            echo "$logsPath Not Eixts"

        else

            /usr/bin/tail -f  $logsPath

            exit $RETVAL

        fi

}

case "$1" in

        start)

                start

                ;;

        stop)

                stop

                ;;

        restart)

                restart

                ;;

        status)

                status

                ;;

                logs)

                logs

                ;;

        *)

                echo $"Usage: $0 {start|stop|restart|status|logs}"

esac

tomcat-server

二、创建运行用户,这里以用户名：tomcat 为例

useradd tomcat

三、把tomcat目录权授

chown -R tomcat.tomcat /usr/local/apache-tomcat-7.0.

注意：

程序用到的所有目录都需要授权给该用户,否则会报权限不足，导致执行失败，执行命令同上

四、开始编写systemctl启动的配置文件

vi /lib/systemd/system/tomcat.service

[Unit]

Description=Tomcat server daemon

Documentation=/data/application/apache-tomcat-8.5.

#注意：一般tomcat服务都是在数据库或redis等启动之后，再运行，确保数据库或redis有制作systemctl，在配置到After，mysql.service redisd.service名字是编写systemctl时的文件名

After=network.target mysql.service redisd.service

[Service]

Type=forking

PIDFile=/usr/local/apache-tomcat-7.0./tomcat.pid

ExecStart=/usr/local/apache-tomcat-7.0./sbin/tomcat-server start

ExecStop=/usr/local/apache-tomcat-7.0./sbin/tomcat-server stop

Restart=/usr/local/apache-tomcat-7.0./sbin/tomcat-server restart

PrivateTmp=True

[Install]

WantedBy=multi-user.target

5、配置Tomcat Pid生产的位置

注意：

确认Tomcat PID必须与 /lib/systemd/system/tomcat.service 配置里面的 PIDFile 保持一致

vi /usr/local/apache-tomcat-7.0./bin/catalina.sh

怱略

#

#   USE_NOHUP       (Optional) If set to the string true the start command will

#                   use nohup so that the Tomcat process will ignore any hangup

#                   signals. Default is "false" unless running on HP-UX in which

#                   case the default is "true"

# -----------------------------------------------------------------------------

CATALINA_PID=/usr/local/apache-tomcat-7.0.94/tomcat.pid

# OS specific support.  $var _must_ be set to either true or false.

cygwin=false

怱略

6、刷新systemctl配置

#重新加载配置文件

systemctl daemon-reload

#服务开启，关闭，重启

systemctl start tomcat.service

systemctl stop tomcat.service

systemctl restart tomcat.service

#设置开机自动启动

systemctl enable tomcat.service

注意：

启动完成后，需要检查进程是否运行
