RedHat下MySQL 5.6 安裝、維護

準備環境：

RedHat 5系統、MySQL 5.6 rpm包

首先 上傳mysql至服務器

一、 解壓縮MySql

[root@localhost]# tar -xvf MySQL-5.6.2_m5-1.rhel5.i386.tar

MySQL-client-5.6.2_m5-1.rhel5.i386.rpm

MySQL-devel-5.6.2_m5-1.rhel5.i386.rpm

MySQL-embedded-5.6.2_m5-1.rhel5.i386.rpm

MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

MySQL-shared-5.6.2_m5-1.rhel5.i386.rpm

MySQL-test-5.6.2_m5-1.rhel5.i386.rpm

二、 安裝MySQL-server包

[root@localhost]# rpm -ivh MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

error:Failed dependencies:

     MySQL conflicts with mysql-5.0.45-7.el5.i386

         MySQL-serverconflicts with mysql-server-5.0.45-7.el5.i386

（安裝失敗，因爲系統先前安裝有mysql,把它卸載掉！再安裝）

        [root@localhost]# rpm -e mysql-5.0.45-7.el5.i386 --nodeps

[root@localhost]# rpm -e mysql-server-5.0.45-7.el5.i386 –nodeps

[root@localhost]# rpm -ivh MySQL-server-5.6.2_m5-1.rhel5.i386.rpm

[root@localhost]# rpm -ivh MySQL-client-5.6.2_m5-1.rhel5.i386.rpm

Preparing...          ########################################### [100%]

   1:MySQL-client    ########################################### [100%]

 

三、 啓動mysql並設置登陸密碼

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

StartingMySQL......[  OK  ]

[root@localhost]# mysqladmin -u rootpassword "123456"

四、 登陸mysql並建立數據庫

[root@localhost]# mysql -u root -p

Enterpassword:

Welcometo the MySQL monitor.  Commands end with; or \g.

Type'help;' or '\h' for help. Type '\c' to clear the current input statement.

 

mysql>create database shiyue;

QueryOK, 1 row affected (0.01 sec)

五、 配置客戶端鏈接

mysql>use mysql;

Readingtable information for completion of table and column names

Youcan turn off this feature to get a quicker startup with -A

 

Database changed

mysql>grant all on *.* to root@"%" identified by "123456";

QueryOK, 0 rows affected (0.00 sec)

 

經過對1042問題代碼的查詢，得出編輯/etc/my.cnf文件，在[mysqld]內添加一行skip-name-resolve

在/etc/目錄下如沒有my.cnf配置文件，則請到/usr/share/mysql/下找到*.cnf文件，拷貝其中的一個到/etc/並更名爲my.cnf

[root@localhost]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

[root@localhost]# vi /etc/my.cnf

 

#Example MySQL config file for medium systems.

#

# Thisis for a system with little memory (32M - 64M) where MySQL plays

# animportant part, or systems up to 128M where MySQL is used together with

#other programs (such as a web server)

#

#MySQL programs look for option files in a set of

#locations which depend on the deployment platform.

# Youcan copy this option file to one of those

#locations. For information about these locations, see:

#http://dev.mysql.com/doc/mysql/en/option-files.html

#

# Inthis file, you can use all long options that a program supports.

# Ifyou want to know which options a program supports, run the program

# withthe "--help" option.

 

# Thefollowing options will be passed to all MySQL clients

[client]

#password       = your_password

port            = 3306

socket          = /var/lib/mysql/mysql.sock

 

# Herefollows entries for some specific programs

 

# TheMySQL server

[mysqld]

port            = 3306

socket          = /var/lib/mysql/mysql.sock

#Don't listen on a TCP/IP port at all. This can be a security enhancement,

# ifall processes that need to connect to mysqld run on the same host.

# Allinteraction with mysqld must be made via Unix sockets or named pipes.
