Tomcat重启脚本restart.sh停止脚本stop.sh

Tomcat重启脚本restart.sh停止脚本stop.sh

Tomcat本身提供了 startup.sh（启动)shutdown.sh(关闭)脚本，我们在部署中经常会出现死进程形象，无法杀掉进程需要查询进程号kill掉才能正常启动。
通过restart.sh脚本来解决这个问题比较好。

PS：经过后期的使用和验证之前写的脚本还是存在问题，可以看我重新写的一篇文章，参考这个可以比较好的解决问题

完美解决Linux服务器tomcat开机自启动问题 - 流风，飘然的风 - 博客园
http://www.cnblogs.com/zdz8207/p/linux-tomcat-autostartup.html

# tail -n 1 /home/server/shichuan/logs/catalina.out |grep 'INFO: Server startup in'
INFO: Server startup in 37417 ms
这个才是真正的启动成功，由于是用autostart的方式会先执行停止后启动，一定不会重新最后一行是之前启动成功留下来的
启动成功需要40秒左右，应该先sleep 足够长的时间再检测，否则会出现启动多个tomcat进程的问题
一次性杀掉多个tomcat进程命令：
ps -ef|grep -v grep|grep /home/server/shichuan/ | grep java |awk '{print "kill -9 "$2}'|sh

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

下面是进过改进版的restart.sh

#!/bin/sh
TOMCAT_PATH=/home/server/shichuan/bin

echo "TOMCAT_PATH is $TOMCAT_PATH"

PID=`ps aux | grep /home/server/shichuan/ | grep java | awk '{print $2}'`

if [ -n "$PID" ]; then
    echo "Will shutdown tomcat: $PID"
    $TOMCAT_PATH/shutdown.sh -force
    sleep
else echo "No Tomcat Process $PID"
fi

ps -ef|grep -v grep|grep /home/server/shichuan/ | grep java |awk '{print "kill -9 "$2}'|sh
sleep 

$TOMCAT_PATH/startup.sh

sleep 

for((i=;i<;i++))
do
    LASTINFO=`tail -n  /home/server/shichuan/logs/catalina.out |grep 'INFO: Server startup in'`
    if [ -n "$LASTINFO" ]; then
        break
    else
        ps -ef|grep -v grep|grep /home/server/shichuan/ | grep java |awk '{print "kill -9 "$2}'|sh
        sleep
        $TOMCAT_PATH/startup.sh
        sleep
    fi
done

----------------------------------------
2.脚本
注意：一台服务器如果运行多个tomcat实例,不要配环境变量，容易启动错误,除了端口变换外，
restart.sh脚本#{tomcat目录}命名要区别,不然kill掉所有tomcat进程
TOMCAT_PATH为tomcat的bin目录，前后不能有反引号
---------------------
restart.sh
---------------------
#!/bin/sh
TOMCAT_PATH=#{tomcat目录}/bin

echo "TOMCAT_PATH is $TOMCAT_PATH"

PID=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`

if [ -n "$PID" ]; then
echo "Will kill tomcat: $PID"
sh "$TOMCAT_PATH/shutdown.sh"
sleep 6
else echo "No Tomcat Process $PID"
fi

PID2=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`

if [ -n "$PID2" ]; then
kill -9 $PID2
echo "Try to kill $PID2"
else echo "No Tomcat Process $PID2"
fi

sh "$TOMCAT_PATH/startup.sh"
sleep 3

PID=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`
if [ -n "$PID" ]; then
echo "\nRestart tomcat successfully!"
else
echo "\nFail to startup tomcat"
exit 1
fi

#!/bin/sh
TOMCAT_PATH=#{tomcat目录}/bin

echo "TOMCAT_PATH is $TOMCAT_PATH"

PID=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`

if [ -n "$PID" ]; then
        echo "Will kill tomcat: $PID"
        sh "$TOMCAT_PATH/shutdown.sh"
        sleep
else echo "No Tomcat Process $PID"
fi

PID2=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`

if [ -n "$PID2" ]; then
        kill - $PID2
        echo "Try to kill $PID2"
else echo "No Tomcat Process $PID2"
fi

sh "$TOMCAT_PATH/startup.sh"
sleep 

PID=`ps aux | grep #{tomcat目录} | grep java | awk '{print $2}'`
if [ -n "$PID" ]; then
        echo "\nRestart tomcat successfully!"
else
        echo "\nFail to startup tomcat"
        exit
fi

===================================

创建文件后需要给执行权限
chmod +x restart.sh
chmod +x stop.sh
或者设置成777等权限
重启tomcat时到bin目录下执行./restart.sh 就可以了

===================================
在window本地编辑sh上传可能遇到下面问题，需要解决编码问题
最好的办法是直接使用vi或vim命令创建文件，把内容粘帖进去

错误1.Linux执行.sh文件，提示No such file or directory的问题的解决方法

错误2.bin/sh^M: bad interpreter: No such file or directory解决方法

原因是.sh脚本在windows系统下用记事本文件编写的。不同系统的编码格式引起的。
1.利用如下命令查看文件格式
:set ff 或 :set fileformat
可以看到如下信息
fileformat=dos 或 fileformat=unix
利用如下命令修改文件格式
:set ff=unix 或 :set fileformat=unix
:wq (存盘退出)

2.最好的办法是直接使用vi或vim命令创建文件，把内容粘帖进去

==================================
[root@iZwz96l7gxttha3j1hk494Z bin]# ./restart.sh
./restart.sh: line 1: #!/bin/sh: No such file or directory
./restart.sh: line 2: #{tomcat目录}/bin: is a directory
TOMCAT_PATH is
No Tomcat Process
