MongoDB在Ubuntu 14.04的配置
我在虚拟机VirtualBox上安装了Ubuntu 14.04,然后在部署MongoDB时遇到了错误。
我在虚拟机VirtualBox上安装了Ubuntu 14.04,然后在部署MongoDB时遇到了错误。
环境:
问题:
在安装mongo-server
$ sudo apt-get install mongodb-server
之后,无法启动MongoDB的服务
$ sudo service mongodb start #why error?
重启虚拟机多次,,删除配置文件并重装mongo-server多次
$ sudo apt-get remove –purge mongodb-server
$ sudo apt-get install mongodb-server
无效。
分析:
查看配置文件/etc/mongodb.conf,根据其中的信息进行追踪到了几个目录,可疑的报错项有:
调整起来依然比较繁琐。
尝试手工启动mongod进程,报空间和权限的错
$ mongod –f /etc/mongodb.conf #权限错误
$ sudo mongod –f /etc/mongodb.conf #空间不够
查看了一下/etc/group和/etc/passwd,已经存在MongoDB相关的项,说明MongoDB账户已经建立好了。
权衡:
直接修改默认日志目录和数据文件的权限依然有可能会出问题。不想在层级的目录权限上纠结。由/etc/passwd知,MongoDB的老家在/home/mongodb,那就让它回老家去吧。
方法:
建立MongoDB的老家,并且给它产权
$ sudo mkdir –p /home/mongodb
$ sudo chown mongodb:mongodb /home/mongodb
调整配置文件,指向老家,加上参数
$sudo vim /etc/mongodb.conf
…
dbpath=/home/mongodb
logpath=/home/mongodb/mongo.log
smallfiles=true
…
再次重启。经此调整以后,已经能够正确维护MongoDB服务
$ sudo service mongodb [start|restart|status]

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
