MongoDB的日志增长的很快,/var所在的空间马上就占满了,即便换到另一个磁盘分区保存日志,日志还是增长的很快,磁盘眼看要告磬。
有一个好办法,就是使用旋转日志。
MongoDB的旋转日志有点怪,Linux下mongd服务接受一个kill -SGIUSR1命令后就立刻将当前日志文件重命名为带日期的文件,然后创建新的日志文件。
不想一般的旋转日志,可以配置旋转策略。不过没关系,经过测试,发送该命令时不会影响到MongoDB的服务。
下面是一个例子,先查找进程id, 然后发送命令。
root@jstc:/etc/init.d# ps -def | grep mongod mongodb 723 1 48 May04 ? 6-22:23:53 /usr/bin/mongod --config /etc/mongodb.conf root 22035 22012 0 20:22 pts/2 00:00:00 grep --color=auto mongod root@jstc:/etc/init.d# kill -SIGUSR1 723 root@jstc:/etc/init.d# cd /home/mongodb/log/ root@jstc:/home/mongodb/log# ls mongodb.log mongodb.log.2014-05-18T12-23-51 root@jstc:/home/mongodb/log# ls -alh total 20G drwxrwxrwx 2 root root 4.0K May 18 20:23 . drwxrwxrwx 4 root root 4.0K Apr 20 21:25 .. -rw-r--r-- 1 mongodb nogroup 34K May 18 20:24 mongodb.log -rwxrwxrwx 1 mongodb nogroup 20G May 18 20:23 mongodb.log.2014-05-18T12-23-51
现在可以将之前20G的日志文件挪走或者删除了。
也可以自己先个定时脚本,定期发送命令给mongod服务。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
