mac之开发中的环境配置

git

ping github.com 

解决githubcom访问慢

GitHub.com域名查询

https://site.ip138.com/github.com/

访问网址http://github.com.ipaddress.com/，分别获取github.com、github.global.ssl.fastly.net对应的IP

github.com，192.30.253.112 192.30.253.113

assets-cdn.github.com，101.184.133

global.ssl.fastly.net，151.101.185.194

编辑文件

git config --edit --global 

设置Git缓存值大小 1048576000

sudo git config --global http.postBuffer 524288000

sudo git config --global https.postBuffer 524288000

git config --list 查看设置值

sudo git config --global http.postBuffer 1048576000

sudo git config --global https.postBuffer 1048576000

git config http.postBuffer 1048576000

需要注意的是http.postBuffer 后，单位是b，524288000B也就500M左右

然后增加最低速度时间

git config --global http.lowSpeedLimit 0

git config --global http.lowSpeedTime 999999

git config http.postBuffer 524288000

//或全局设置

git config --global http.postBuffer 524288000.

git clone --depth=1 http://xxx.git

git fetch --unshallow

mac 下 Homebrew 可能会在 install 或者 update 的时候会很慢，卡很久。

两种方式来解决：

一、直接关闭brew执行命令时的自动更新

# 1. 编辑配置文件
vim ~/.bash_profile

# 2. 文件内新增一行
export HOMEBREW_NO_AUTO_UPDATE=true

# 3. 重新加载配置文件
source ~/.bash_profile

二、替换brew源

cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

#替换homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
brew update

# 备用地址-1
cd "$(brew --repo)"
git remote set-url origin https://git.coding.net/homebrew/homebrew.git
brew update

# 备用地址-2
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew-core.git
brew update

PS：官方默认信息

# 1. 重置brew.git
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

# 2. 重置homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git
