【转】ubuntu MySQL采用apt-get install安装目录
一).?ubuntu下mysql安装布局: /usr/bin????????????????????? 客户端程序和mysql_install_db
/var/lib/mysql??????????? 数据库和日志文件
/var/run/mysqld??????? 服务器
/etc/mysql ? ? ? ? ????? 配置文件my.cnf
/usr/share/mysql?????? 字符集,基准程序和错误消息
/etc/init.d/mysql??????? 启动mysql服务器 二).?设置mysql服务器随开关机自动启动和关闭: 系统 -> 系统管理 -> 服务
进行到“服务设置”窗口后,激活mysql数据库服务即可 三).?修改mysql数据库文件的存储目录: ? MySQL默认的数据文件存储目录为/var/lib/mysql。假如要把目录移到/home/data下需要进行下面几步: 1、home目录下建立data目录
cd /home
mkdir data
Copy after login
2、把MySQL服务进程停掉:
mysqladmin -u root -p shutdown
Copy after login
3、把/var/lib/mysql整个目录移到/home/data
mv /var/lib/mysql /home/data/
Copy after login
这样就把MySQL的数据文件移动到了/home/data/mysql下 4、找到my.cnf配置文件 如果/etc/目录下没有my.cnf配置文件,请到/usr/share/mysql/下找到*.cnf文件,拷贝其中一个到/etc/并改名为my.cnf)中。命令如下:
[root@test1 mysql]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
Copy after login
5、编辑MySQL的配置文件/etc/my.cnf 为保证MySQL能够正常工作,需要指明mysql.sock文件的产生位置。修改socket=/var/lib/mysql/mysql.sock一行中等号右边的值为:/home/mysql/mysql.sock 。操作如下:
vi  my.cnf  (用vi工具编辑my.cnf文件,找到下列数据修改之)
# The MySQL server
[mysqld]  port = 3306
#socket  = /var/lib/mysql/mysql.sock(原内容,为了更稳妥用“#”注释此行)
socket  = /home/data/mysql/mysql.sock (加上此行)
Copy after login
6、修改MySQL启动脚本/etc/init.d/mysql 最后,需要修改MySQL启动脚本/etc/init.d/mysql,把其中datadir=/var/lib/mysql一行中,等号右边的路径改成你现在的实际存放路径:home/data/mysql。
[root@test1 etc]# vi /etc/init.d/mysql
#datadir=/var/lib/mysql(注释此行)
datadir=/home/data/mysql (加上此行)
Copy after login
7、重新启动MySQL服务
/etc/init.d/mysql start 或用reboot命令重启Linux 如果工作正常移动就成功了,否则对照前面的7步再检查一下。还要注意目录的属主和权限。 四).?配置mysql数据库的INNODB存储引擎: 1 . 查看mysql存储引擎情况: 登录mysql数据库,在mysql>提示符下搞入show engines;命令。发现: InnoDB | YES,说明此mysql数据库服务器支持InnoDB引擎。
2. 设置InnoDB为默认引擎:在配置文件my.cnf中的 [mysqld] 下面加入default-storage-engine=INNODB 一句,保存。
3. 重启mysql服务器:mysqladmin -u root -p shutdown(回车),sudo /etc/init.d/mysql start(回车)。
4. 登录mysql数据库,在mysql>提示符下搞入show engines;命令。如果出现 InnoDB |DEFAULT,则表示我们 设置InnoDB为默认引擎成功。
ps:?这里我用重启命令sudo /etc/init.d/mysql restart,出现错误信息, 所以用了上面(步骤3)那种关闭服务又启动的笨方法。 ? 转自:http://m.blog.csdn.net/blog/goodspringin/9258883
