## 替换 yum repo 源
|
||||||
|
|
||||||
|
由于 CentOS 默认 yum 源,访问速度很慢,所以推荐使用国内镜像。
|
||||||
|
|
||||||
|
使用方法:执行以下任意命令即可执行脚本。
|
||||||
|
|
||||||
|
```sh
|
||||||
|
curl -o- https://raw.githubusercontent.com/dunwu/os-tutorial/master/codes/linux/ops/sys/yum/change-yum-repo.sh | bash
|
||||||
|
wget -qO- https://raw.githubusercontent.com/dunwu/os-tutorial/master/codes/linux/ops/sys/yum/change-yum-repo.sh | bash
|
||||||
|
```
|
||||||
|
|
||||||
|
## 安装基本的命令工具(可选)
|
||||||
|
|
||||||
|
工具清单(可以根据需要,在 install-cmd-tool.sh 中把不需要的工具注掉):
|
||||||
|
|
||||||
|
```
|
||||||
|
# 核心工具:df、du、chkconfig
|
||||||
|
# 网络工具:ifconfig、netstat、route
|
||||||
|
# IP工具:ip、ss、ping、tracepath、traceroute
|
||||||
|
# DNS工具:dig、host、nslookup、whois
|
||||||
|
# 端口工具:lsof、nc、telnet
|
||||||
|
# 下载工具:curl、wget
|
||||||
|
# 防火墙工具:iptables
|
||||||
|
# 编辑工具:emacs、vim
|
||||||
|
# 流量工具:iftop、nethogs
|
||||||
|
# 抓包工具:tcpdump
|
||||||
|
# 压缩工具:unzip、zip
|
||||||
|
# 版本控制工具:git
|
||||||
|
```
|
||||||
|
|
||||||
|
使用方法:执行以下任意命令即可执行脚本。
|
||||||
|
|
||||||
