  • CentOS日常维护及常用脚本

    [root@192-16.x.x xiewenming]# curl myip.ipip.net
当前 IP：42.62.x.x  来自于：中国 北京 北京  联通/电信

     www.17ce.com  cdn解析网站测试

    如果遇到 -bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory，解决办法如下：

    vi /etc/environment

add these lines...

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

    结束php进程，主进程除外

    ps -ef|grep php|grep -v grep|cut -c 9-15|xargs kill -9

    用指定用户执行脚本或命令

    su - tomcat -c /usr/local/tomcat/bin/startup.sh

    切换root执行

     sudo sh tomcat.sh start

    查查哪个目录的inode节点使用的多

    [root@opt]# df  -i
Filesystem     Inodes IUsed IFree IUse% Mounted on
/dev/vda2        576K  497K   80K   87% /
tmpfs            235K     5  235K    1% /dev/shm
[root@192-168-3-157 var]# for i in /*; do echo $i; find $i| wc -l;done
...
/var
363753
[root@var]# for i in /var/*; do echo $i; find $i| wc -l;done
[root@var]#time find /var/spool/postfix/maildrop -type f -delete

    其它其中删除目录下面有大量文件的方法

    #相同的测试数据
#方法1
time rsync -a --delete /dev/null / test/ 
--16s
#方法2
time find ./ -type f -exec rm {} ;
--43 分钟
#方法3
time find ./ -type f -delete       
--9分钟
#方法4 python
import os
import time
stime=time.time()
for pathname,dirnames,filenames in os.walk('/home/username/test'):
     for filename in filenames:
         file=os.path.join(pathname,filename)
         os.remove(file)
 ftime=time.time()
 print ftime-stime
--8分钟

    ssh -t 可以创建一个虚拟终端，这样就可以执行一些如 vim / htop 之类的命令，也包括 sudo 之类

     ssh -t 192.168.56.134 "vi xiewenming.txt"

    sudo 使用需要tty可以通知/etc/sudoers 默认是需要的，有时远程执行sudo命令提示需要一个tty，可以把默认下面这行注释掉

    [root@xiewenming]# grep tty /etc/sudoers
Defaults    requiretty

    使用$!调用上一个命令的最后一个参数

    [root@linux-node1 ~]# ll -d /etc/sysconfig/network-scripts/
drwxr-xr-x. 2 root root 4096 Dec  5 03:39 /etc/sysconfig/network-scripts/
[root@linux-node1 ~]# cd !$
cd /etc/sysconfig/network-scripts/
[root@linux-node1 network-scripts]#

    当系统可用内存不足是可以用下面的命令回收系统可用内存命令，

    Nov 22 09:47:43 192-168-3-150 kernel: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) 这里有报错内存死锁，有时候用下面这条命令可以解决问题

     echo 1 > /proc/sys/vm/drop_caches

    查看系统ip连接及流量统计信息

    iotop可以查看IO读写请求

     删除用户及家目录

    userdel -r 用户名

     清空nginx cache脚本

    #!/bin/bash

    URL_NAME=$(echo -n $PURGE_URL | md5sum | awk '{print $1}')

     yum报错问题

    You could try using --skip-broken to work around the problem,rpm -Va --nofiles --nodigest问题

    解决方法

    cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak/
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
rpm -vhi https://mirrors.aliyun.com/epel/epel-release-latest-6.noarch.rpm 
yum clean all 
rpm --rebuilddb 
    yum update

    有时候下载第三方yum源版本一定要和系统对应上

     I just spotted you have a mix of .el6. and /el7/ packages listed tehre so 
    I suspect you've installed the wrong yum repo for Centreon. You need the one to match your 
    CentOS version which appears to be 6 and you have installed the repo for 7. Remove it, add the correct one, run yum clean all then try again.
