Linux下设置开机自启动tomcat

centos7 设置tomcat开机自启动

在tomcat/bin 目录下面，增加setenv.sh配置，catalina.sh启动的时候会调用，同时配置java内存参数
vim setenv.sh

#tomcat启动pid

export JAVA_HOME=/opt/jdk8
export CATALINA_HOME=/opt/tomcat8
export CATALINA_BASE=/opt/tomcat8
#add tomcat pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
#add java opts
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"

增加tomcat.service在/usr/lib/systemd/system目录下增加tomcat.service，目录必须是绝对目录
vim /usr/lib/systemd/system/tomcat.service

[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/opt/tomcat8/tomcat.pid
ExecStart=/opt/tomcat8/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
3.使用tomcat.service

systemctl enable tomcat.service
systemctl start tomcat.service
systemctl stop tomcat.service
systemctl restart tomcat.service

因为配置pid，在启动的时候会在tomcat的根目录下生产tomcat.pid文件，停止后删除

--------------------------------------------------------------------------------------------------------------------------------

方法一：
编辑/etc/rc.d/rc.local，在最后添加如下代码：

export JAVA_HOME=/usr/java/jvm/java-openjdk
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
export PATH=$PATH:$JAVA_HOME/bin
/usr/local/tomcat/bin/startup.sh start

--------------------------------------------------------------------------------------------------------------------------------
方法二：
linux 下tomcat开机自启动
修改Tomcat/bin/startup.sh 为:

export JAVA_HOME=/usr/java/jvm/java-openjdk
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
export PATH=$PATH:$JAVA_HOME/bin
export CATALINA_HOME=/usr/local/tomcat
/usr/local/tomcat/bin/catalina.sh start

在/etc/rc.d/rc.local中加入:

/usr/local/tomcat/bin/startup.sh

------------------------------------------------------------------------------------------------------------------------------

方法三：

1、把下面的代码保存为tomcat文件，并让它成为可执行文件 chmod 755 tomcat.

#!/bin/bash
#
# kenny [e-mail]
# /etc/rc.d/init.d/tomcat
# init script for tomcat precesses
#
# processname: tomcat
# description: tomcat is a j2se server
# chkconfig: 2345 86 16
# description: Start up the Tomcat servlet engine.

if [ -f /etc/init.d/functions ]; then
. /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ]; then
. /etc/rc.d/init.d/functions
else
echo -e "/atomcat: unable to locate functions lib. Cannot continue."
exit -1
fi

RETVAL=$?
CATALINA_HOME="/usr/local/tomcat"

case "$1" in
start)
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
$CATALINA_HOME/bin/startup.sh
fi
;;
stop)
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
$CATALINA_HOME/bin/shutdown.sh
fi
;;
*)
echo $"Usage: $0 {start|stop}"
exit 1
;;
esac

exit $RETVAL

2、将tomcat文件拷贝到/etc/init.d/下，并运行：chkconfig --add tomcat

3、在tomcat/bin/catalina.sh文件中加入以下语句：

export JAVA_HOME=/usr/java/jvm/java-openjdk
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=/usr/local/tomcat
export CATALINA_TMPDIR=/usr/local/tomcat/temp

启动tomcat： service tomcat start
停止tomcat： service tomcat stop
