Hard disk partitioning recommendations for CentOS installation system

I. Description of common mount points
In general, there are at least two mount points in the Linux system, namely / (root directory) and swap(swap partition), in which,/ is required;

See below for details:

When installing the system, select Creat custom layout to customize the partition
Recommended list of directories to mount:

/ root directory, storing system commands and user data, etc. 　
/boot boot loader static link file for Linux boot-related programs

/home User directory, storing data for ordinary users / tmp temp file / usr is where the Red Hat Linux system holds the software and, if possible, the maximum space should be allocated to it /usr/local the self-installed program is installed here / var constantly changing data, some server services are placed below.

/OPT Additional Application Packages

In general, we need at least two partitions, a swap partition, and a "/" partition, but it is easy to manage by dividing some common and important mount points into other partitions. General one/partition, one/usr partition, one/home partition, and one/var partition. All of these can be changed according to your own needs.

Two. Recommended system partitioning Scheme
/swap Directory 8G # #内存小于4G的为内存的2倍 memory is greater than 4G and memory size consistent
/boot Directory 100M
/root directory 30g-50g # #较大一些 Force primary partition
/var directory 30g-50g # #存放各种日志文件最好较大一些
/usr directory 50g-100g # #用于个人配置应用程序, especially to install some of the more prone to log larger programs if Wowza tomcat, etc., it is best to divide the larger
/Home 10G
/opt 10G
/tmp 10G

Other remaining space can be divided into business applications, can be assigned according to their own needs
If the installation database can be partitioned/data for storing database files
The installation Web service can be divided into/webroot for storing web pages and so on
