Git更安全的强制推送 -force-with-lease

Git 的 push --force 具有破坏性，因为它无条件地覆盖远程存储库，无论你在本地拥有什么。使用这个命令，可能覆盖团队成员在此期间推送的所有更改。然而，有一个更好的办法，当你需要强制推送，但仍需确保不覆盖其他人的工作时，-force-with-lease 这条指令选项可以帮助到你。

统计php-fpm内存占用总量

ps auxf|grep www_sockets | grep -v grep | awk ‘{print $6}’ | awk ‘{sum+=$1} END {print “Memory =”, sum/1024/1024, “GB”}’

根据需求定制 红色部分是你要修改的部分

git子模块支持分支

You can set the submodule to track a particular branch (requires git 1.8.2+), which is what we are doing with Komodo, or you can reference a particular repository commit (the later requires updating the main repository whenever you want to pull in new changes from the module – i.e. updating the commit hash reference).

git submodule add -b master https://github.com/Komodo/trackchanges.git src/modules/trackchanges

php iOS内购验证库

项目地址：

https://github.com/sn01615/ios-iap-php

安装：

composer require sn01615/ios-iap-php

使用：


use sn01615\iap\ios\Verify;

include "../vendor/autoload.php";

$cc = new Verify();

$receipt = ".."; // 凭据

$cc->endpoint(true);// 可选切换到沙盒环境

$vv = $cc->query($receipt);

// 打印结果
var_dump($vv);

PHP7 扩展Hello world 

[root@local2 ext]# ./ext_skel --extname=Hello

Creating directory Hello
Creating basic files: config.m4 config.w32 .gitignore Hello.c php_Hello.h CREDITS EXPERIMENTAL tests/001.phpt Hello.php [done].

To use your new extension, you will have to execute the following steps:

1.  $ cd ..
2.  $ vi ext/Hello/config.m4
3.  $ ./buildconf
4.  $ ./configure --[with|enable]-Hello
5.  $ make
6.  $ ./sapi/cli/php -f ext/Hello/Hello.php
7.  $ vi ext/Hello/Hello.c
8.  $ make

Repeat steps 3-6 until you are satisfied with ext/Hello/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.

[root@local2 ext]# 

# phpize 
# ./configure --enable-Hello
# make
# php -i | grep Hello
# php Hello.php

Linux 系统级别PATH添加目录

修改此文件 /etc/profile.d/sh.local ，添加如下内容

pathmunge /usr/local/bin after
# pathmunge 是个shell函数 after 表示在路径后面添加，不加after 表示在路径签名加
# /usr/local/bin 是我们要添加到PATH的路径
