1 mysql实战二进制安装

数据库和web分离,web服务器上如何安装mysql?

通过mysql的包,调用Php的函数,make install后即可。

useradd mysql -s /sbin/nologin �CM

tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz

mv mysql-5.5.32-linux2.6-x86_64/ /application/mysql-5.5.32/

ln -s /application/ mysql-5.5 /application/mysql

mkdir /application/mysql/data

chown -R mysql.mysql /application/mysql/data/

chmod -R 1777 /tmp/    调整/tmp权限,否则初始化会错误

[root@hexudong mysql]# ./mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql

初始化数据库

when specifying MySQL privileges !

Installing MySQL system tables...

OK

Filling help tables...

OK                 出现两个OK 代表成功

 

[root@hexudong mysql]# cp support-files/my-small.cnf /etc/my.cnf

cp: overwrite `/etc/my.cnf'? y

 

更改/etc/init.d/mysqld 文件

46 basedir=/application/mysql

 47 datadir=/application/mysql/data

 

echo "export PATH=/application/mysql/bin:$PATH" >>/etc/profile

source /etc/profile

 

Data 里面的库

performance_schema    mysql 自己的维护的库

mysql                 用户权限等库

 

二进制安装,默认为/usr/local 路径,要更改配置文件里的路径。

 

出现的问题解决:

[root@mysql1 scripts]# ./mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql

 

FATAL ERROR: Could not find my_print_defaults

 

The following directories were searched:

 

    /application/mysql//bin

    /application/mysql//extra

 

If you compiled from source, you need to run 'make install' to

copy the software into the correct location ready for operation.

 

If you are using a binary release, you must either be at the top

level of the extracted archive, or pass the --basedir option

pointing to that location.

 

[root@mysql1 scripts]# ./mysql_install_db --basedir=/application/mysql-5.5.32/ --datadir=/application/mysql-5.5.32/data/ --user=mysql

安装路径不正确!!!!

 

mysql报错解决

[root@hexudong mysql]# /etc/init.d/mysqld start

Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/hexudong.oldboy.pid).

[root@hexudong mysql]# killall mysqld

多killall 几次即可。

 

问题一:(李新宇)

[root@c66-kslx mysql]# /etc/init.d/mysqld start     

Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/c66-kslx.pid).

问题原因:权限问题,没有授权MySQL管理数据库文件

解决方法:

chown -R mysql.mysql /application/mysql/

 

问题二:(肖海波)

ERROR: 1  Can't create/write to file '/tmp/#sql_6a81_0.MYI' (Errcode: 13)

问题原因:权限问题

解决方法:chmod -R 1777 /tmp

 

问题三:mysql包传送有问题

解决方法:rz 不要打勾。ASCII

 

问题四:(卢世祺)

[root@TraumLou application]# mysql

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

问题原因:初始化问题

解决方法:删除data目录重建,重新初始化

 

问题五:(断翅)

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2

问题原因:服务没启动

 

mysql 多实例:

mkdir /data/{3306,3307}/data -p

把data 文件,放到跟下解压。

/application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data/ --user=mysql

初始化第一个实例

./mysql_install_db --basedir=/application/mysql/ --datadir=/data/3307/data/ --user=mysql

初始化第二个实例

 

授予执行权限

[root@mysql1 scripts]# find /data -type f -name mysql  | xargs ls

/data/3306/mysql  /data/3307/mysql

[root@mysql1 scripts]# find /data -type f -name mysql  | xargs chmod +x

 

授予myssql权限

chown mysql.mysql -R /data

 

关闭数据库:

/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql.sock shutdown

 

启动数据库:

mysql -uroot -p3306 -S /data/3306/mysql.sock
