How to write a mongodb service monitoring script under Linux
到history中看下启动命令:
复制代码 代码如下:
/usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/ --logpath=/data/mongodb.log --logappend &
原来如此!因为他没有用nohup启动,所以只要他的终端离线或者关闭,mongodb就会自动退出了!解决办法很简单,如下启动即可:
复制代码 代码如下:
nohup /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/ --logpath=/data/mongodb.log --logappend >/dev/null 2>&1 &
这样敲命令也着实苦逼,所以从网上找了一个mongodb服务脚本就舒服多了:
#!/bin/sh # #mongod - startup script for mongod # # chkconfig: - 85 15 # description: mongodb database. # processname: mongod # source function library . /etc/rc.d/init.d/functions # things from mongod.conf get there by mongod reading it # options options=" --dbpath=/home/data/mongodb/ --logpath=/home/data/mongodb/mongodb.log --logappend &" #mongod mongod="/usr/local/mongodb/bin/mongod" lockfile=/var/lock/subsys/mongod start() { echo -n $"starting mongod: " daemon $mongod $options retval=$? echo [ $retval -eq 0 ] && touch $lockfile } stop() { echo -n $"stopping mongod: " killproc $mongod -quit retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile } restart () { stop start } ulimit -n 12000 retval=0 case "$1" in start) start ;; stop) stop ;; restart|reload|force-reload) restart ;; condrestart) [ -f $lockfile ] && restart || : ;; status) status $mongod retval=$? ;; *) echo "usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}" retval=1 esac exit $retval
将代码保存到 /etc/init.d/mongodb,然后使用 chmod +x /etc/init.d/mongodb 添加执行权限。
现在,就可以使用 service 命令来控制mongodb了:
复制代码 代码如下:
service mongodb start|stop|restart #或 /etc/init.d/mongodb start|stop|restart

Finally, I installed andres-montanez/recommendations-bundle through Composer, which not only solved my problem, but also greatly improved the performance of the recommendation system. You can learn composer through the following address:
