Tomcat 起動スクリプト

Tomcatを起動するとき毎回startup.shを叩かないでスクリプトから起動できるなら良いと思って実装してみました。

  • tomcat配置ディレクトリは/usr/tomcat/tomcat-7.0.27 とします。
#!/bin/bash
#
# tomcat     This shell script takes care of starting and stopping Tomcat
#
# chkconfig: - 80 20
#
### BEGIN INIT INFO
# Provides: tomcat
# Required-Start: $network $syslog
# Required-Stop: $network $syslog
# Default-Start:
# Default-Stop:
# Short-Description: start and stop tomcat
### END INIT INFO

tomcat_pid() {

}

        echo "Tomcat is already running (pid: $pid)"

    fi
    return 0
}

stop() {
    pid=$(tomcat_pid)
    if [ -n "$pid" ]
    then
        echo "Stopping Tomcat"
        /bin/su - -c "cd $TOMCAT_HOME/bin && $TOMCAT_HOME/bin/shutdown.sh" $TOMCAT_USER

    let kwait=$SHUTDOWN_WAIT
    count=0
    count_by=5
    until [ `ps -p $pid | grep -c $pid` = '0' ] || [ $count -gt $kwait ]
    do
        echo "Waiting for processes to exit. Timeout before we kill the pid: ${count}/${kwait}"
        sleep $count_by
        let count=$count+$count_by;
