update – 主机软件博客

昨天一台代维客户的cPanel机器计划更新软件包
尝试yum update后
出现一堆依赖包错误

其中就包括
httpd-mmn = 20051115 is needed by mod_wsgi-3.2-3.el6.x86_64
这个是非常古老了 cPanel官方论坛的解释是这个非必要
然后直接删了

后面还有一堆依赖包错误
检查发现客户安装了另外几个RPM源
rpmforge是其中之一 Continue reading “httpd-mmn = 20051115 is needed by mod_wsgi-3.2-3.el6.x86_64”

Linux 怎么查看内存大小?

使用free命令

free --help
root@deweb2 [~]# free --help
free: invalid option -- '-'
usage: free [-b|-k|-m|-g] [-l] [-o] [-t] [-s delay] [-c count] [-V]
  -b,-k,-m,-g show output in bytes, KB, MB, or GB  输出格式 比如 free -m =以兆显示
  -l show detailed low and high memory statistics
  -o use old format (no -/+buffers/cache line)
  -t display total for RAM + swap
  -s update every [delay] seconds
  -c update [count] times
  -V display version information and exit

free --help

root@deweb2 [~]# free --help

free: invalid option -- '-'

usage: free [-b|-k|-m|-g] [-l] [-o] [-t] [-s delay] [-c count] [-V]

-b,-k,-m,-g show output in bytes, KB, MB, or GB 输出格式比如 free -m =以兆显示

-l show detailed low and high memory statistics

-o use old format (no -/+buffers/cache line)

-t display total for RAM + swap

-s update every [delay] seconds

-c update [count] times

-V display version information and exit

常用显示方式
free -m

root@deweb2 [~]# free -m
             total       used       free     shared    buffers     cached
Mem:         32080       3239      28841          0        227       1817
-/+ buffers/cache:       1194      30885
Swap:         8031          0       8031

root@deweb2 [~]# free -m

total used free shared buffers cached

Mem: 32080 3239 28841 0 227 1817

-/+ buffers/cache: 1194 30885

Swap: 8031 0 8031

32G内存以G显示通常会显示31G
这个是M G bit的历史遗留问题….
