cassandra nosql autorestart服務與chkserv.d

Question

我沒有太多的Linux經驗，所以它可能是我失去了一些明顯的東西。

但是...我試圖把Cassandra nosql放在CentOS上的chkserv.d中，所以它在中斷時自動啓動。我設法把它放在那裏，當chkservd被破壞時它被正確識別。我把這樣的：

root@server [/etc/chkserv.d]# cat cassandra 
service[cassandra]=x,x,x,/etc/init.d/cassandra start,cassandra,root 

被執行的「卡桑德拉啓動」時的問題是，在cassandra.out日誌我得到：

/opt/cassandra/cassandra_home/bin/cassandra: line 141: exec: java: not found 

在卡桑德拉腳本的141行是：

EXEC $ numactl的 「$ JAVA」 $ JVM_OPTS $ cassandra_parms -cp 「$ CLASSPATH」 $道具 「$類」 < & - &

和所有環境變量正確擴展：

當我手工啓動卡桑德拉腳本，或者去和等啓動/ init.d /的卡桑德拉開始，一切都正確啓動。

百萬美元的問題 - 我錯過了什麼？

謝謝

只需要設置JAVA_HOME環境變量。現在一切都按預期工作。

$ CASSANDRA_HOME/bin/cassandra.in.sh中的未註釋行。
