如何在linux下寫個東東監(jiān)測tomcat服務(wù)是否運行？

sakulagi

tmocat的進程是一個java進程吧？有tomcat這個命令么？

sarahxu

后來我直接在crontab -e
*/2 * * * * /usr/java/tomcat/bin/./startup.sh
里直接讓它重啟,結(jié)果在log里面輸出的是
This environment variable is needed to run this program
The JAVA_HOME environment variable is not defined
可是我的java環(huán)境變量是好的啊

我也用 java進程檢查了 ps -A | grep java
也是不可以

你從startup.sh里能看到到底啟動的是什么程序
不行你把ps -A的結(jié)果貼上來看一眼

另外crontab和shell環(huán)境不一樣，你在SHELL里設(shè)置的環(huán)境變量對cron不起作喲嘎

請幫個忙吧已經(jīng)兩天沒有睡了

就是到tomcat目錄下面輸入命令./startup.sh

河里的魚

至于這么麻煩嗎?

running=`ps -ef |grep /usr/local/tomcat |grep -v grep`
if [ "x" != "x$running" ]
then
        echo "Tomcat already running!"
        exit 0
fi
su - -c "/usr/local/tomcat/bin/startup.sh &"
sleep 3
running=`ps -ef |grep /usr/local/tomcat |grep -v grep`
if [ "x" = "x$running" ]
then
        echo "Tomcat start error!"
        exit 1
else
        echo "Tomcat restore succeed"
        exit 0
fi

請不要笑話小妹, 俺原來對linux都不懂,后來老板一定要讓俺解決,俺實在一點辦法也沒有

我在tomcat路徑下面直接輸入命令startup.sh不可以但是輸入./startup.sh就可以了,
這是為什嗎啊?是我的java的path設(shè)置不對嗎
