gitlab-ce安装后的提示
[root@ecs-340051 opt]# cat /etc/gitlab/initial_root_password
# WARNING: This value is valid only in the following conditions
# 1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails[‘initial_root_password’]` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
# 2. Password hasn’t been changed manually, either via UI or via command line.
#
# If the password shown here doesn’t work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
Password: XyQdnmCOPZfI+XutyMa40QPecLrKAQ1a456S8=
# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
翻译如下：
[root@ecs-340051 opt]# cat /etc/gitlab/initial_root_password
# WARNING:该值仅在以下条件下有效
# 1。如果手动提供(在’ gitlab.rb ‘文件中通过’ GITLAB_ROOT_PASSWORD ‘环境变量或’ gitlab_rails[‘initial_root_password’] ‘设置，它是在数据库第一次播种(通常是第一次重新配置运行)之前提供的。
# 2。密码没有被手动修改，无论是通过UI还是通过命令行。
#如果这里显示的密码不起作用，您必须在https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password后重置管理员密码。

php文件上传基础知识
PHP
$_FILES 是一个预定义的数组，用来获取通过 POST 方法上传文件的相关信息。如果为单个文件上传，那么 $_FILES 为二维数组；如果为多个文件上传，那么 $_FILES 为三维数组。
建立一个 file.html 演示上传文件，其中的代码如下：
<html>
<head></head>
<body></body>
<form enctype=“multipart/form-data” action=“file.php” method=“POST”>
Send this file: <input name=“userfile” type=“file” />
<input type=“submit” value=“Send File” />
</form>
</html>
新建一个用于接收文件信息的 PHP 文件 file.php，代码如下：
<?php
echo “<pre>”;
print_r($_FILES);
?>
在 file.html 页面选择文件后，单击 Send File 按钮，将会在页面输出以下信息：
Array
(
[userfile] => Array
(
[name] => Screen Shot 2016-05-12 at 18.13.24.png
[type] => image/png
[tmp_name] => /private/var/tmp/phplVHp3W
[error] => 0
[size] => 344925
)
)
javascript 的join()方法
自己百度去
join() 方法用于把数组中的所有元素转换一个字符串。
元素是通过指定的分隔符进行分隔的。
