linux使用git时传输速度太低，提速

下面是我自己写的脚本：

#!/bin/bash
# author  TommyWang
# website  http://dynmi.top


fast_ip=`nslookup github.global.ssl.fastly.Net|egrep ‘[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}‘`

fast_ip=${fast_ip##*:}

git_ip=`nslookup github.com|egrep ‘[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}.[[:digit:]]{1,3}‘`

git_ip=${git_ip##*:}

echo "${fast_ip}"
echo "${git_ip}" 

sed -i ‘/github.global.ssl.fastly.Net/d‘ /etc/hosts
sed -i ‘/github.com/d‘ /etc/hosts

echo "github.global.ssl.fastly.Net${fast_ip}
github.com${git_ip}" >> /etc/hosts

sudo systemctl restart nscd

 

将它加入到crontab 定时执行中，必须是root身份，在/etc/crontab中追加（修改脚本地址）

10 10   * * *   root    /home/dynmi/Documents/essential_bash/refresh_git_ip.sh
