本文介绍了solr 守护进程的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想用守护进程运行 solr.我在另一篇文章中看到有一个您可以运行的 init.d 脚本,但它在我的 ubuntu 环境中似乎有问题.每当我尝试使用/etc/init.d/solr start 运行脚本或尝试手动运行以下行时:
I would like to run solr with daemon. I saw in another post there is a init.d script you can run but it seems to have problems in my ubuntu environment. whenever i try to run the script with /etc/init.d/solr start or when i try to run the below line manually:
daemon java -jar start.jar
错误:
daemon: invalid option -- 'j'
有什么想法吗?谢谢.
推荐答案
以下是用于守护 Solr 的工作脚本.这里有几个重要的注意事项:
Below is a working script for daemonizing Solr. Couple important notes here:
- 您需要为守护程序脚本设置 chdir,否则加载配置文件时会出错.
- 这将允许您启动/停止/状态/重启 Solr.
- 这是一个似乎对我有用的简单版本.
脚本如下:
#!/bin/sh
# Prerequisites:
# 1. Solr needs to be installed at /usr/local/solr/example
# 2. daemon needs to be installed
# 3. Script needs to be executed by root
# This script will launch Solr in a mode that will automatically respawn if it
# crashes. Output will be sent to /var/log/solr/solr.log. A pid file will be
# created in the standard location.
start () {
echo -n "Starting solr..."
# start daemon
daemon --chdir='/usr/local/solr/example' --command "java -jar start.jar" --respawn --output=/var/log/solr/solr.log --name=solr --verbose
RETVAL=$?
if [ $RETVAL = 0 ]
then
echo "done."
else
echo "failed. See error code for more information."
fi
return $RETVAL
}
stop () {
# stop daemon
echo -n "Stopping solr..."
daemon --stop --name=solr --verbose
RETVAL=$?
if [ $RETVAL = 0 ]
then
echo "done."
else
echo "failed. See error code for more information."
fi
return $RETVAL
}
restart () {
daemon --restart --name=solr --verbose
}
status () {
# report on the status of the daemon
daemon --running --verbose --name=solr
return $?
}
case "$1" in
start)
start
;;
status)
status
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $"Usage: solr {start|status|stop|restart}"
exit 3
;;
esac
exit $RETVAL
