Add swap partitions under centos. this method is not limited to centos, linux is applicable to the following commands. you must operate the Java code dd if =/dev/zero of =/home/swap bs = 1024 count = 512000 www.2cto.com under the root account to create/home/ swap is a partition file. The file size is 512000 blocks. generally, 1 block is 1 K, so the space is 512 MB. Then convert the partition into a swap partition. Java code/sbin/mkswap/home/swap then use this swap partition. Make it valid. Java code/sbin/swapon/home/swap now use the free-m command to check the memory and swap partition size, and it is found that the space is increased by MB. However, after the computer is restarted, it is found that swap is still so large, the new swap is not automatically started, and manual start is required. Then we need to modify the/etc/fstab file and add the following line www.2cto.com/home/swap defaults 0 0. then you will find that swap space increases after your machine starts automatically.
