linux 问题和使用

centos vim 中文乱码

vim ~/.vimrc
set fileencodings=utf-8,gb2312,gb18030,gbk,ucs-bom,cp936,latin1
set enc=utf8
set fencs=utf8,gbk,gb2312,gb18030

杀死相关进程

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

ps aux|grep sync_alarm_data|awk '{print $2}'|xargs kill -9

nohup和screen 使用

screen -S cxn ：创建一个进程，后缀名为cxn
screen -ls ：查看所有进程
screen -r 进程号：进入一个进程
kill -9 进程号：杀死进程
screen -wipe：移除死掉的进程
ctrl+a，再按d即可挂起

下载指令

1. 指令一

wget --debug --header="User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36 Edg/91.0.864.59" https://zf.sc.chinaz.com/Files/DownLoad/font/xmfont3616efn.rar

1. 指令二

wget --no-check-certificate -qO client-linux.py 'https://raw.githubusercontent.com/cppla/ServerStatus/master/clients/client-linux.py'

查看端口使用情况

1. 查看端口使用情况

iptables -nL

1. 查看端口占用

lsof -i:80

服务器之间复制文件

scp root@192.168.8.61:/opt/fubang  ./

查看所有系统服务

systemctl list-units --type=service

替换yum 源

1. 进入 yum 源配置目录

   cd /etc/yum.repos.d

2. 备份原 yum 源基础配置文件

   mv CentOS-Base.repo CentOS-Base.repo.bak

3. 切换 yum 基础源至阿里源

   wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

4. 清空缓存

   yum clean all && yum makecache

配置系统代理 这种方式只在当前窗口生效

1. 本机代理

vim /etc/profile

export proxy="http://127.0.0.1:10809"     
export http_proxy=$proxy        
export https_proxy=$proxy       
export ftp_proxy=$proxy     
export no_proxy="localhost, 127.0.0.1, ::1" 

source /etc/profile

2. docker 容器代理 （写入到 /etc/profile 或 /etc/environment 文件中）

vim /etc/profile

export proxy="http://172.17.0.1:10809"     
export http_proxy=$proxy        
export https_proxy=$proxy       
export ftp_proxy=$proxy     
export no_proxy="localhost, 127.0.0.1, ::1"   

source /etc/profile

3. 局域网代理

vim /etc/profile

export proxy="http://192.168.8.10:10809"       
export http_proxy=$proxy        
export https_proxy=$proxy       
export ftp_proxy=$proxy     
export no_proxy="localhost, 127.0.0.1, ::1"   

source /etc/profile

查找并替换

1. 查看包含118.190.73.218内容的文件

find ./ -type f -regex ".*\.xml\|.*\.js.*\|.*\.properties" | xargs grep "118.190.73.218"

2. 查找完成后进行替换为old_text为new_text

find ./ -type f -regex ".*\.xml\|.*\.js.*\|.*\.properties" | xargs perl -pi -e"s/old_text/new_text/g"

3. 查找完成后进行替换为old_text为new_text

find /home/user/documents -type f -exec sed -i 's/old_text/new_text/g' {} +

4. 内容替换 单个文件

sed -i 's/old_text/new_text/g' file.txt

unzip 解压乱码

unzip -O GBK xxx.zip -b 路径
