'''It is strongly recommended that you backup your database at regular intervals and before an upgrade.'''

'''強烈建議定時備份，每次更新前也做一次備份。.'''

[[WordPress:Restoring Your Database From Backup|Restoring your database from backup]] is then possible if something goes wrong.

[[WordPress:Restoring Your Database From Backup|從你的備份中恢復數(shù)據(jù)庫]]可以在你遇到問題時使用。

== Using phpMyAdmin ==

[[WordPress:phpMyAdmin]] is the name of the program used to manipulate your database. 

Information below has been tried and tested using phpMyAdmin versions 2.5.3, 2.5.7-pl1, and 2.6.1-pl3 running on Unix.

== 使用 phpMyAdmin ==

[[WordPress:phpMyAdmin| phpMyAdmin]]是一個用來操作你的數(shù)據(jù)庫的程序. 

下邊的信息已經通過使用phpMyAdmin versions 2.5.3, 2.5.7-pl1，和2.6.1-pl3運行在Unix系統(tǒng)上的測試。

=== Backup Process with phpMyAdmin ===
<ol>[[WordPress:Image:podz_backup_1.jpg|thumb|Image#1]]
<li>Log into phpMyAdmin on your server</li>
[[WordPress:Image:podz_backup_2.jpg|thumb|Image#2]]

<li>From the main login screen, select 'Databases' (Image#1)</li>
[[WordPress:Image:podz_backup_3.jpg|thumb|Image#3]]

<li>Now click the name of your database - or your WordPress database if you have several databases. (Image#2)</li>
[[WordPress:Image:podz_backup_4.jpg|thumb|Image#4]]

<li>The next screen will show you all the tables inside your WordPress database.<br />
Ignore those, and click the 'Export' tab on the top set of tabs. (Image#3)</li>

<li>Look at the left box at the top of the Export section. All the tables in the database you selected are in that box.(Image#4)</li>
[[WordPress:Image:podz_backup_5.jpg|thumb|Image#5]]
<ul>
<li>If you have other programs that use the database, then choose only those tables that correspond to your wordpress install. They will be the ones with that start with "wp_" or whatever 'table_prefix' you specified in your 'wp-config.php' file.</li>

<li>If you only have your WordPress blog installed, in the left column, click 'Select All'.</li>
</ul>

<li>Ensure that the SQL button is selected too. (Image#5)</li>
<ul>
<li>The SQL section</li>

<li>Tick the following boxes: Structure, 'Add DROP TABLE', 'Add AUTO_INCREMENT' and 'Enclose table and field names with backquotes'</li></ul>

<li>The DATA section</li>
<ul>[[WordPress:Image:podz_backup_6.gif|thumb|Image#6]]

<li>Leave the boxes inside this section unticked, but make sure to keep the checkbox next to the "DATA" heading checked.</li>
</ul>

<li>Tick the 'Save as file' option, and leave the template name alone.<br />
For now, select 'None' for compression.</li>

<li>Now click 'Go' and you should be prompted for a file to download. Save the file to your computer. (Image#6)<br />
Depending on the database size, this may take a few moments.</li>

<li>Once that download is complete, check the 'zipped' option, click 'Go', and download the next file.<br />
If you wanted, you could download a backup in each of the compression formats. Your choice.</li>

<li>You have now backed up your database.</li>


'''Remember''' - you have NOT backed up the files and folders - such as images - but all your posts and comments are now safe.</li>
</ol>
=== 使用phpMyAdmin的備份過程 ===
<ol>[[WordPress:Image:podz_backup_1.jpg|thumb|Image#1]]
<li>在你的服務器上登陸phpMyAdmin </li>
[[WordPress:Image:podz_backup_2.jpg|thumb|Image#2]]


<li>從主登陸界面選擇 'Databases' (Image#1)</li>
[[WordPress:Image:podz_backup_3.jpg|thumb|Image#3]]

[[WordPress:Image:podz_backup_5.jpg|thumb|Image#5]]
<ul>
<li>如果你有別的使用數(shù)據(jù)庫的程序,那么選擇那些符合 wordpress安裝的表格 . 它們以 "wp_" 或者是 'table_prefix' 開頭，你在你的 'wp-config.php' 文件中詳細指定過的.</li>

<li>如果你只安裝了 WordPress blog, 在左邊欄中點擊 'Select All'.</li>
</ul>

<li>確保SQL 按鈕被選中. (Image#5)</li>
<ul>
<li> SQL 部分</li>

<li>勾選一下方框: Structure, 'Add DROP TABLE', 'Add AUTO_INCREMENT' 和 'Enclose table and field names with backquotes'</li></ul>

<li> DATA部分</li>
<ul>[[WordPress:Image:podz_backup_6.gif|thumb|Image#6]]

<li>這部分之內的方框不要勾選，但是要確定在保持"DATA"旁邊的復選框是選中狀態(tài).</li>
</ul>

<li>勾選 'Save as file' 操作, 留下一個模板名字.<br />
現(xiàn)在壓縮選中 'None'.</li>

<li>現(xiàn)在點擊 'Go' ，你應該被提示說有個文件下載，保存這個文件到你的電腦上. (Image#6)<br />
根據(jù)數(shù)據(jù)庫的大小，這會花去你幾分鐘的時間.</li>

<li>下載完成后，查看'zipped' 操作, 點擊 'Go', 下載另外一個文件.<br />
如果你想的話，你可以下載每個文件的壓縮格式的備份。你的選擇.</li>

<li>現(xiàn)在，你的數(shù)據(jù)庫已經備份完畢.</li>


'''記住''' – 你沒有備份文件和文件夾 – 如圖片- 但是所有你的文章和評論現(xiàn)在已經是安全的了.</li>
</ol>

== Using Straight MySQL Commands ==

phpMyAdmin can not handle large databases so using straight MySQL code will help.

1. Change your directory to the directory you want to dump things to:

<pre>user@linux:~> cd files/blog</pre>

2. Use <code>mysqldump</code> to dump all database tables. To dump only certain tables from the database, give their names at the place shown by <code>(tablename tablename tablename)</code>, and omit the parentheses <code>( )</code> in any case. (For help, try: <code>man mysqldump</code>.):

<pre>user@linux:~/files/blog> mysqldump --add-drop-table -h mysqlhostserver
 -u mysqlusername -p databasename (tablename tablename tablename) | bzip2
 -c > blog.bak.sql.bz2

Enter password: (enter your mysql password)
user@linux~/files/blog></pre>

<pre>
Example:
mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp | bzip2 -c > blog.bak.sql.bz2

Enter password: my-password
user@linux~/files/blog>
</pre>

The <code>bzip2 -c</code> after the | (pipe) means the backup is compressed on the fly, and the <code>&gt; blog.bak.sql.bz2</code> sends the <code>bzip</code> output to a file named <code>blog.bak.sql.bz2</code>.  It does in one line the same thing that these two commands do:
<pre>
mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp > blog.bak.sql
bzip2 blog.bak.sql
</pre>

== 直接使用 MySQL 命令==

phpMyAdmin 不能掌控大的數(shù)據(jù)庫所以用直接 MySQL 代碼會有所幫助 will help.

1. 把目錄改成你想儲存臨時數(shù)據(jù)的地方:

<pre>user@linux:~> cd files/blog</pre>

2. 使用 <code>mysqldump</code> 來儲存所有的數(shù)據(jù)庫表格. 想儲存某個特定的數(shù)據(jù)庫表格,在通過<code>(tablename tablename tablename)</code>顯示出來的地方給它們命名, 忽略<code>( )</code> 中的圓括號. (想獲得幫助信息, 嘗試: <code>man mysqldump</code>.):

<pre>user@linux:~/files/blog> mysqldump --add-drop-table -h mysqlhostserver
 -u mysqlusername -p databasename (tablename tablename tablename) | bzip2
 -c > blog.bak.sql.bz2

Enter password: (enter your mysql password)
user@linux~/files/blog></pre>

<pre>
Example:
mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp | bzip2 -c > blog.bak.sql.bz2

Enter password: my-password
user@linux~/files/blog>
</pre>

| (pipe)之后的<code>bzip2 -c</code>語句意思是備份已經被壓縮, <code>&gt; blog.bak.sql.bz2</code>發(fā)送<code>bzip</code>到一個名字叫做的文件中。 <code>blog.bak.sql.bz2</code>. 和下面兩個命令做的是同樣的事情：
<pre>
mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp > blog.bak.sql
bzip2 blog.bak.sql
</pre>

== Using MySQL Administrator ==
MySQL Administrator is a program for performing administrative
operations, such as configuring your MySQL server, monitoring its
status and performance, starting and stopping it, managing users and
connections, performing backups, restoring backups and a number of
other administrative tasks.
You can perform most of those tasks using a command line interface
such as that provided by [http://dev.mysql.com/doc/mysql/en/mysqladmin.html '''mysqladmin'''] or
[http://dev.mysql.com/doc/mysql/en/mysql.html '''mysql'''], but MySQL Administrator is advantageous in the following respects:

*Its graphical user interface makes it more intuitive to use.

*It provides a better overview of the settings that are crucial for the performance, reliability, and security of your MySQL servers.

*It displays performance indicators graphically, thus making it easier to determine and tune server settings.

*It is available for Linux, Windows and MacOS X, and allows a remote client to backup the database across platforms. As long as you have access to the MySQL databases on the remote server, you can backup your data to wherever you have write access.

*There is no limit to the size of the database to be backed up as there is with phpMyAdmin.

MySQL Administrator is designed to work with MySQL servers versions 4.0 and above.

== 使用 MySQL 管理員 ==
MySQL 管理員是一個執(zhí)行管理的程序。
操作, 如設置你的MySQL 服務器, 監(jiān)測它的狀態(tài)和表現(xiàn), 開始或者是停止, 管理用戶和連接，執(zhí)行備份，儲存?zhèn)浞莸鹊纫幌盗衅渌芾砣蝿?。你可以使用命令行界面?zhí)行這些任務中的大多數(shù)。如由[http://dev.mysql.com/doc/mysql/en/mysqladmin.html '''mysqladmin'''] 或者
[http://dev.mysql.com/doc/mysql/en/mysql.html '''mysql''']提供的, 但是MySQL 管理員在下面這些方面更具有優(yōu)勢：

*圖形用戶界面讓它更容易使用

*它提供了更好的對你的MySQL服務器的界面，可靠性和安全性至關緊要的設置總覽。

*它顯示性能指示器是圖形化的，這更容易決定和調整服務器設置。

* Linux, Windows and MacOS X都可以使用, 允許遠程客戶端備份數(shù)據(jù)庫交叉平臺. 只要你進入了遠程MySQL 數(shù)據(jù)庫, 你就可以備份你的數(shù)據(jù)到任何具有寫入權限的地方。

*對備份數(shù)據(jù)庫的大小沒有限制，因為有phpMyAdmin.

MySQL Administrator 是為MySQL servers 版本 4.0 及以上設計使用的。

=== Getting MySQL Admin ===

MySQL Admin may be downloaded from [http://dev.mysql.com/downloads/administrator/1.0.html the MySQL.Com site]. Installation binaries and documentation may also be found there.

=== 得到MySQL 管理 ===

MySQL 管理可以從[http://dev.mysql.com/downloads/administrator/1.0.html the MySQL.Com site]下載. 安裝文件也可以從這里找到.

=== Backing Up the Database ===
This assumes you have already installed MySQL Admin and set it up so that you can login to the MySQL Database Server either locally or remotely. Refer to the documentation that comes with the installation package of MySQL Admin for your platform for installation instructions.

1. Open the MySQL Admin client and login as you had previously set up to do.

2. From the icon menu on the left hand side of the client window select Backup.

3. If you have not already created a Backup Project, do this now by clicking on the "New Project" button at the lower part of the window and type in a name for the Backup Project where prompted.

4. Select one or more databases that you want to Backup (in the MySQL Admin client these are called a "Schema" (pl. "Schemata")). Add them to the Backup Content window on the right using the right-pointing arrow button.

5. When you have selected the Schema(ta), you can save the Backup Project. Or you may simply choose to Backup Now using the button on the lower right of the window.

6. A dialogue will come up asking you where to put the Backup. Enter the pathname or browse to the location using the dialogue.

7. Assuming all is correct (and you have write permissions in the directory to which you are writing the Backup), the backup will complete shortly.

=== 備份數(shù)據(jù)庫 ===
這里假設你已經安裝了MySQL Admin 并設置好，這樣你就可以本地或者遠程登陸MySQL Database Server. 查閱安裝說明中的MySQL Admin安裝包文件。

1. 打開MySQL Admin 客戶端登陸.

2. 從程序窗口左邊的圖像菜單中選擇Backup.

3. 如果你沒有創(chuàng)建一個Backup 項目, 現(xiàn)在點擊窗口下部的 "New Project" 按鈕，為Backup Project輸入一個名字.

4. 選擇一個或者更多你想備份的數(shù)據(jù)庫(在MySQL Admin 程序中，這些叫做 "Schema" (pl. "Schemata")). 使用指向右邊的箭頭把它們加入到右邊的Backup Content 窗口 。

5. 當你選擇了Schema(ta), 你可以保存?zhèn)浞蓓椖? 或者你可以簡單的選擇右下方的Backup Now 按鈕.

6. 一個對話框將會產生，詢問你要把備份保存在什么地方。輸入路徑名字或者通過瀏覽保存。

7. 假設所有步驟都正確 (并且你在寫備份的目錄擁有寫入權限), 備份會很快完成.

=== Restoring From a Backup ===

1. Open the MySQL Admin client and login as you had previously set up to do.

2. From the icon menu on the left hand side of the client window select Restore.

3. Click the "Open Backup File" button on the lower right of the window.

4. Type in or browse to the Schema(ta) backup file and select. Click "Open".

5. The Target Schema(ta) will most likely be the "Original Location", or you may choose an alternate location using the drop-down menu.

6. Click the "Start Restore" button on the lower right of the window. The database restore will commence.

=== 從備份中恢復 ===

1. 打開MySQL Admin 程序登陸.

2. 從圖形界面的程序窗口左手邊選擇 Restore.

3. 點擊右下方的"Open Backup File" 按鈕。

4. 輸入或者瀏覽至 Schema(ta) 備份文件，選擇，點擊"Open".

5. 目標 Schema(ta) 通常會在"Original Location", 或者你可以使用下拉菜單選擇一個替代位置.

6. 點擊右窗口下方 "Start Restore" 按鈕。 數(shù)據(jù)庫恢復開始
