ubuntu下安装mysql（二进制）到自定义目录

一，安装

1, 下载 mysql二进制文件： http://dev.mysql.com/downloads/mysql/ 页面，选择linux generic ，然后选择最后一个 “Linux - Generic (glibc 2.5) (x86, 32-bit), Compressed TAR Archive” 进行下载 （32或者64根据是实际情况）

2, 切换到root 用户

3, 先创建一个group和一个属于这个组的user

shell> groupadd group1

shell> useradd -r -g group1 user1

3, 解压下载的二进制包， 到自己要放的位置， 如home/user/mysql

4, cd home/user/mysql

5, 赋予操作权限：

chown -R user1 .

chgrp -R group1 .

6, scripts/mysql_install_db --user=user1 为user1安装数据库 （需要libaio包，使用新德里帮忙下一下）

7, 赋权限：

chown -R root .

chgrp -R group1 .

chown -R root .

chown -R user1 data

8,启动mysql后台服务：

bin/mysqld_safe --user=user1 &

如果没有报错，那么就是服务器的启动成功。

测试一下：

新开一个terminal，

cd home/user/mysql/bin

./mysqladmin version

正确的话 就会显示版本信息之类的 并且没有其他错误报出。

二，增加安全性

cd home/user/mysql

bin/mysql_secure_installation

然后具体步骤的一些 信息如下：

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

Set root password? [Y/n] y

New password:

Re-enter new password:

Password updated successfully!

Reloading privilege tables..

... Success!

By default, a MySQL installation has an anonymous user, allowing anyone

to log into MySQL without having to have a user account created for

them. This is intended only for testing, and to make the installation

go a bit smoother. You should remove them before moving into a

production environment.

Remove anonymous users? [Y/n] y

... Success!

Normally, root should only be allowed to connect from &＃39;localhost&＃39;. This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y

... Success!

By default, MySQL comes with a database named &＃39;test&＃39; that anyone can

access. This is also intended only for testing, and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n] y

- Dropping test database...

... Success!

- Removing privileges on test database...

... Success!

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n] y

... Success!

三，便利设置

1,将mysql的路径加到环境变量中去：

sudo gedit /etc/profile

然后加入：

1, export MYSQL_HOME=home/user/mysql;

2,在PATH=XX后面加入 :$MYSQL_HOME/bin
