記憶git帳號密碼
如果經常在修改git內容
每次的pull, push 都輸入帳號密碼是非常煩人的
可以利用以下指令來記憶帳號密碼
git config --global credential.helper 'cache --timeout 86400'
以上例子為 86400 秒，也就是一天
如果要永久儲存
可以輸入
git config --global credential.helper 'cache --timeout 86400'
但會把帳號密碼明碼寫在 ~/.git-credentials
就看個人習慣

freebsd 安裝 redis
redis 跟 memcached 一樣，是一套存儲在記憶體中的key-value nosql 資料庫
預設的port 是 tcp : 6379
常用在網站的cache, 目的在不用過於頻繁的直接讀寫資料庫
在 FreeBSD 上面安裝很簡單
# cd /usr/ports/databases/redis
# make install clean
===> CONFIGURATION NOTE:
To setup "redis" you need to edit the configuration file:
/usr/local/etc/redis.conf
To run redis from startup, add redis_enable="YES"
in your /etc/rc.conf.
===> SECURITY REPORT:
This port has installed the following files which may act as network
servers and may therefore pose a remote security risk to the system.
/usr/local/bin/redis-sentinel
/usr/local/bin/redis-cli
/usr/local/bin/redis-server
/usr/local/bin/redis-check-rdb
/usr/local/bin/redis-benchmark
This port has installed the following startup scripts which may cause
these network services to be started at boot time.
/usr/local/etc/rc.d/sentinel
/usr/local/etc/rc.d/redis
If there are vulnerabilities in these programs there may be a security
risk to the system. FreeBSD makes no guarantee about the security of
ports included in the Ports Collection. Please type 'make deinstall'
to deinstall the port if this is a concern.
For more information, and contact details about the security
status of this software, see the following webpage:
http://redis.io/
啟動 redis
# /usr/local/etc/rc.d/redis onestart
開機時自動啟用
# vi /etc/rc.conf

GeoIP + Bind + view 針對國家回應不同dns位置
假設一個跨國企業網站
讓來自台灣的訪客可以造訪台灣機房
來自日本的訪客可以造訪日本機房
其餘的訪客造訪另一個機房
cd /etc
wget http://geoip.site/download/MaxMind/GeoIP.acl
vi named.conf
include "/etc/GeoIP.acl";
view "TW" {
match-clients { TW; };
zone "TW-myip.pass.tw" {
type master;
file "JP.myip.pass.tw.zone";
};
};
view "JP" {
match-clients { JP; };
zone "JP-myip.pass.tw" {
type master;
file "JP.myip.pass.tw.zone";
};
};
view "ANY" {
match-clients { any; };
zone "ANY-myip.pass.tw" {
type master;
file "JP.myip.pass.tw.zone";
};
};
最後重啟named 即可

關閉php 彩蛋
可以先測試一下自己有沒有把網站資訊不小心洩漏出來
http://your-web-site/?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
如何關閉
vi php.ini
expose_php = On
修改成
expose_php = Off
重啟apache 或是 php-fpm 即可

使用php mail() 寄信並指定 envelope-from
email 的傳遞有點像現實生活種的郵差先生在寄信
分為信封寄件者和信紙寄件者
envelope-from 顧名思義，就是寫在信封或是包裹上面的寄件者
所以是給郵差和MTA 看的
信紙寄件者，通常就是我們常看到信件的最下面寫著 XXX 敬上 .. 之類的稱呼
是給收件者看的，通常outlook 及其他MUA顯示的是這個欄位
php mail()
bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )
通常我們都會把From: 寫在第四個變數
但是這只是修改信紙寄件者
郵差先生看到的寄件者還是系統自動幫你帶的，不一定會跟From 會一樣
往往這樣可能會造成一些退信的狀況
建議From: 和 envelope from 都可以改成一致
避免不必要的困擾
example:
<?php
mail('ethan@a.com','Hello World!','Good morning!','From: service@b.com','-f service@b.com');
?>

使用Rufus 製作FreeBSD開機usb 隨身碟
下載 Rufus
https://rufus.akeo.ie/?locale=zh_TW
因為 Rufus 不支援 FreeBSD iso檔
所以我們選img檔案
以FreeBSD 11.1 為例
檔名為 FreeBSD-11.1-RELEASE-amd64-memstick.img
選擇剛剛下載的img檔，並下拉選擇DD映像
最後執行即可

移除比小強還強的 EFI 系統磁碟分割區
如果拿到一顆硬碟開心的要把它重新分割
但是始終保留一個 EFI 系統磁碟分割區 怎麼砍也砍不掉
這時候可以
用系統管理員身分執行cmd
輸入diskpart
|
C:\Windows\system32>diskpart Microsoft DiskPart 版本 6.1.7601 |
列出接在電腦的硬碟
|
DISKPART> list disk 磁碟 ### 狀態 大小 可用 Dyn Gpt |
選擇要清理的硬碟
|
DISKPART> select disk 1 磁碟 1 是所選擇的磁碟。 DISKPART> list disk 磁碟 ### 狀態 大小 可用 Dyn Gpt |
確定真的不留戀的話，輸入clean
|
DISKPART> clean DiskPart 成功地清理了磁碟。 DISKPART> |
回頭看windows 的磁碟管理，可以看到磁碟機已經乾乾淨淨啦

啟用 drupal 8 clean URLs
安裝完drupal 8 之後，系統會需要你做一些簡單的設定
如果在需求檢查步驟出現以下的警告訊息
Your server is capable of using clean URLs, but it is not enabled. Using clean URLs gives an improved user experience and is recommended
表示你的 drupal 目錄無法使用rewrite 功能
如果是apache請確認以下設定
LoadModule rewrite_module libexec/apache24/mod_rewrite.so
Alias /drupal "/usr/local/www/drupal8"
<Directory "/usr/local/www/drupal8">
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>

Varnish 下的 backend 取得實際的client ip
預設的狀況下，varnish 下面的backend , 諸如 apache 或是 nginx ... 等
接到 http 的 請求時，client ip 都是varnish 的ip
如此一下，程式無法針對來源做出判斷，geoip 也無法知道來源是屬於哪個國家
解決這個問題步驟如下
編輯 varnish/default.vcl
sub vcl_recv {
###
if (req.restarts == 0) {
if (req.http.x-forwarded-for) {
set req.http.X-Forwarded-For = req.http.X-Forwarded-For + ", " + client.ip;
} else {
set req.http.X-Forwarded-For = client.ip;
}
}
###
}
修改backend log format 設定，以apache為例
#LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
即可在access_log 中看到實際使用者來源ip

CentOS 安裝 nslookup
nslookup這個指令對於網路除錯來說，應該是很多人都很習慣的工具
如果發現安裝好的Linux系統少了這個指令
[root@example ~]# nslookup myip.pass.tw
-bash: nslookup: command not found
[root@example ~]# which nslookup
/usr/bin/which: no nslookup in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

FreeBSD 10.x 安裝 Mongodb 3.4
更新ports tree
# portsnap fetch extract update
安裝 mongodb
# cd /usr/ports/databases/mongodb34
勾選相依套件選項
# make config-recursive
開始漫長的編譯，可以去泡個茶先
# make install clean
預設設定檔路徑
/usr/local/etc/mongodb.conf
設定開機自動執行
# vi /etc/rc.conf
mongod_enable="YES"
重開機或手動啟動mongodb
/usr/local/etc/rc.d/mongod start
OR
service mongod start
查看服務狀況，預設監聽 tcp 27017 port , 僅綁定 127.0.0.1 本機可以連線
可依需求修改設定檔

freebsd透過ports安裝套件前，一次設定相依套件
假設如果要在freebsd透過ports 安裝apache24
除了是漫長的compile 過程外
再來就是不時會被其他相依套件中斷，提醒你要勾選相依套件的選項
想要好好去廁所大個便都不行
如果要解決這個問題，好好的去蹲廁所
可以參考以下步驟
# cd /usr/ports/www/apache24
# make config-recursive
===> Setting user-specified options for apache24-2.4.26 and dependencies
接下來一一勾選相依套件的選項後
# make insall clean
即可

freebsd 出現 You have security/openssl installed but do not have DEFAULT_VERSIONS+=ssl=openssl set in your make.conf
如果你除了內建的openssl 又自行安裝比較新版的openssl
在安裝其他套件時出現以下警告訊息
/!\ WARNING /!\
You have security/openssl installed but do not have
DEFAULT_VERSIONS+=ssl=openssl set in your make.conf
解決方式
echo 'DEFAULT_VERSIONS+=ssl=openssl' >> /etc/make.conf
即可

解決nginx+php-fpm : FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream 錯誤訊息
安裝好nginx + php-fpm 後，ngixn error log出現以下錯誤訊息
2017/06/28 10:06:46 [error] 949#100116: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.77.252, server: ng.test.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com:8080"
預設參考範例
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
修改為以下設定
location ~ \.php$ {
#root html;
root "你的網頁路徑";
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
重新啟動nginx 即可

rsync 只監聽特定IP
假設我們的rsync server 有兩張網卡
一張對外、一張對內
如果rsync 的服務只需要對內，不希望外面的人來打擾
當然可以用防火牆來阻擋
但如果不方便用防火牆的話
也可以透過修改設定檔來達成
如果是獨立執行的
參考一下man 說明
address
You can override the default IP address the daemon will listen
on by specifying this value. This is ignored if the daemon is
being run by inetd, and is superseded by the --address com-
mand-line option.
可以修改 rsyncd.conf
address = 要LISTEN的IP
如果是透過xinetd 啟動的
可以修改 /etc/xinetd.d/rsync
加入 bind = 要LISTEN的IP
或是考慮其他參數
如
only_from 或是 only_from
