CentOS教程之CentOS功能测试工具 C sysbench
如果您觉得本篇CentOSLinux教程讲得好，请记得点击右边漂浮的分享程序，把好文章分享给你的小伙伴们！sysbench是一款开源的多线程功能测试工具，能够实行CPU/内存/线程/IO/数据库等方面的功能测试。数据库今朝撑持MySQL/Oracle/PostgreSQL。本文只是复杂演示一下几种测试的用法，后续筹办使用sysbench来对MySQL举行一系列的测试。详细的一些参数设置，必要依据分歧的测试请求来举行调剂.编译装置
#wget-chttp://sourceforge.net/projects/sysbench/files/sysbench/0.4.12/sysbench-0.4.12.tar.gz/download
#tarzxvfsysbench-0.4.12.tar.gz
#cdsysbench-0.4.12
#./configure&&make&&makeinstall
假如必要测试Oracle/PostgreSQL，则在configure时必要加上Cwith-oracle大概Cwith-pgsql参数
参数
#./sysbench

CentOS教程之CentOS功能测试工具 C sysbench
这种补充有助于他人在邮件列表/新闻组/论坛中搜索对你有过帮助的完整解决方案，这可能对他们也很有用。 掌握在Linux系统中安装软件，在安装Linux工具盘后大致日常所需的软件都会有,一般网络提供下载的软件都会有安装说明。 硬盘安装及光盘安装，清楚了解安装Linux应注意的有关问题，如安装Linux应在最后一个分区内，至少分二个分区。 随着Linux应用的扩展，出现了不少Linux社区。有一些非常优秀的社区往往是Linux高手的舞台，如果在探讨高级技巧的论坛张贴非常初级的问题经常会没有结果。 可以说自己收获很大，基本上完成了老师布置的任务，对于拔高的题目没有去做，因为我了解我的水平，没有时间和精力去做。? 如果你想深入学习Linux,看不懂因为文档实在是太难了。写的最好的、最全面的文档都是英语写的,最先发布的技术信息也都是用英语写的。 掌握硬件配置，如显卡，声卡，网卡等，硬件只要不是太老或太新一般都能被支持，作为一名Linux系统管理员建议多阅读有关硬件配置文章，对各种不支持或支持不太好的硬件有深刻的了解。 我们自学，就这个循环的过程中，我们学习了基本操作，用vi，shell，模拟内存的分配过程等一些OS管理。
