linux及git記錄

清空Github上某個檔案的歷史

git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch app/img/*' --prune-empty --tag-name-filter cat -- --all

git push origin master --force

rm -rf .git/refs/original/

git reflog expire --expire=now --all

git gc --prune=now

git gc --aggressive --prune=now

使用iconv 對大檔案編碼轉換GB2312 - UTF8

iconv -f gb2312 -t utf-8//IGNORE av-ed2k-合集.data > 日文教學日文教學.txt av-ed2k-合集.data

Nginx 上限制單IP 單位時間的請求數，以及單IP 的並發連線數

http {

limit_req_zone $binary_remote_addr zone=one:10m rate=8r/s;

server {
    location /search/ {
        limit_req zone=one burst=5;
    }

使用Nginx 限制頁存取權

命令行登陸權限

sudo apt-get install apache2-utils
sudo htpasswd -c /etc/nginx/.htpasswd myusername
server {
  listen       80;
  server_name  ip_address;

  location /backend {
      root   /var/www/sunzhongwei.com;
      index  index.html index.htm;

      auth_basic "Restricted";                                
      auth_basic_user_file /etc/nginx/.htpasswd;  
  }
}

sudo /etc/init.d/nginx reload

github

ssh-keygen -t rsa -C "郵件"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/MZero/.ssh/id_rsa):

。點選右上角的Account Settings—>SSH and GPG keys —> new SSH key

$ ssh -T git@github.com
若有You've successfully authenticated提示,說明成功了

pullull/push專案的時候總是提示要輸入使用者名稱密碼的解決方案

git config --global credential.helper store

伺服器設定允許mysql遠端登入

vi /etc/sysconfig/iptables

-A INPUT -m tcp -p tcp --dport 3306 -j ACCEPT

service iptables restart
grant all on aaa.* to "root"@xx .yy.zz.cc identified by "123";
flush privileges; aaa.* to "root"@"%" identified by "123";

ssh 設定密碼登入

ssh-keygen -t rsa -C "you@homestead"

$ sudo vim /etc/ssh/sshd_config

RSAAuthentication yes

PubkeyAuthentication yes
AuthorizeKeyFile ~/.ssh/authorized_keys
service sshd restart
將公鑰檔案的內容追加到~/.sk/authorized_hdkeysauthorized_hdkeys600,000,000 且將檔案帶. /authorized_keys

$ vim .bash_profile
alias c14='ssh [username]@[server_ip] (-i ~/.ssh/[私鑰檔案])'

$ source .bash_profile

$ c14
$

Nginx 報502 的解決思路

nginx報錯，查看nginx日誌排錯
nginx報502 bad gate way一般是因為沒有配置好php-fpm
修改nginx或php-fpm設定檔之後重啟生效和http2 模組支援

curl https://nginx.org/download/ng... |

tar xzf - && cd nginx-* # get latest nginx & extract it

./configure [old_config_arguments] --withHun-http_ssl_ssl_ --with-http_v2_module # 前面[old_config_arguments] 可以從nginx -V 裡copy
make
sudo make install
listen 443 ssl http2;
ssl_certificate /home/brook/ssl/home/brook/ssl/homessl_certificate/home/brook/ssl/home/brook/ssl/ /domain.key;
ssl_dhparam /home/brook/ssl/dhparams.pem;
ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:RSACDH+A2562628:RSA RSA+ 3DES:!MD5;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_session_cache shared:SSL:50m； -Transport-Security max-age=31536000;
service reload nginx

pphpmyadmin 缺少mcrypt 擴充

sudo apt-get install php-mcrypt libmcrypt libmcrypt-devel
sudo ln -s /etc/php5/bache-mcrypt-devel
sudo ln -s /etc/php5/aches-mcrypt-devel

sudo-ln -s /etc/php5/aches-mcrypt-devel

sudo-ln -s /etc/php5/bache-mcrypt-devel .

curl指令查看請求回應時間方法

curl -o /dev/null -s -w %{time_namelookup}::%{time_connect}::%{time_starttransfer}::%{time_total}:​​:%{speed_download} "n" http://www.36nu.com

用github來展示你的前端頁

創建專案新分支透過專案新專案通過專案/(user_name|org_name).g... 存取

一個更簡單的方式來實現：將程式碼上傳至倉庫後在settings裡配置下GitHub Pages為你想展示的分支就行了
