参考别人的经验，加上自己的理解，完成下面的动作。
==============================
【源码安装 mysql-5.6.10】
(1)解压 mysql 源码
<a href="http://my.oschina.net/moooofly/blog/128203#">?</a>
1
2
<code>[root@betty me_wget]</code><code># tar zxvf mysql-5.6.10.tar.gz</code>
<code>[root@betty me_wget]</code><code># cd mysql-5.6.10</code>
(2)创建 mysql 的安装目录及数据库存放目录
<code>[root@betty mysql-5.6.10]</code><code># mkdir -p /usr/local/mysql</code>
<code>[root@betty mysql-5.6.10]</code><code># mkdir -p /usr/local/mysql/data</code>
(3)创建 mysql 用户及用户组
3
4
5
<code>[root@betty mysql-5.6.10]</code><code># groupadd mysql</code>
<code>groupadd: group mysql exists</code>
<code>[root@betty mysql-5.6.10]</code><code># useradd -r -g mysql mysql</code>
<code>useradd</code><code>: user mysql exists</code>
<code>[root@betty mysql-5.6.10]</code><code>#</code>
因为我之前已经安装过一次，所以上面说用户组和用户已存在。
(4)安装 mysql
参数说明：
-dcmake_install_prefix=/usr/local/mysql //安装目录
-dinstall_datadir=/usr/local/mysql/data //数据库存放目录
-ddefault_charset=utf8 //使用utf8字符
-ddefault_collation=utf8_general_ci //校验字符
-dextra_charsets=all //安装所有扩展字符集
-denabled_local_infile=1 //允许从本地导入数据
执行 cmake 命令。

<code>support-files</code><code>/mysql</code><code>.server to the right place</code><code>for</code> <code>your system</code>
<code>please remember to set a password for the mysql root user !</code>

<code> </code><code>.</code><code>/bin/mysqladmin</code> <code>-u root password</code><code>'new-password'</code>
<code> </code><code>.</code><code>/bin/mysqladmin</code> <code>-u root -h betty password</code><code>'new-password'</code>
<code>alternatively you can run:</code>
<code> </code><code>.</code><code>/bin/mysql_secure_installation</code>
<code>which</code> <code>will also give you the option of removing the</code><code>test</code>
<code>databases and anonymous user created by default. this is</code>
<code>strongly recommended</code><code>for</code> <code>production servers.</code>
<code>see the manual</code><code>for</code> <code>more</code> <code>instructions.</code>
<code>you can start the mysql daemon with:</code>
<code> </code><code>cd</code> <code>. ; .</code><code>/bin/mysqld_safe</code> <code>&</code>
<code>you can</code><code>test</code> <code>the mysql daemon with mysql-</code><code>test</code><code>-run.pl</code>
<code> </code><code>cd</code> <code>mysql-</code><code>test</code> <code>; perl mysql-</code><code>test</code><code>-run.pl</code>
<code>please report any problems with the .</code><code>/bin/mysqlbug</code> <code>script!</code>

<code>[root@betty mysql]</code><code># ll /etc/init.d/mysql </code>
<code>-rwxr-xr-x 1 root root 10650 may 6 14:11</code><code>/etc/init</code><code>.d</code><code>/mysql</code>
