RPM方式安裝MySQL5.6源碼

RPM方式安裝MySQL5.6

a. 檢查MySQL及相關RPM包，是否安裝，如果有安裝，則移除（rpm –e 名稱）

[root@localhost ~]# rpm -qa | grep -i mysql
mysql-libs-5.1.66-2.el6_3.x86_64
[root@localhost ~]# yum -y remove mysql-libs*

b. 下載Linux對應的RPM包，如：CentOS6.4_64對應的RPM包，如下：

[root@localhost rpm]# ll
total 74364
-rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm
-rw-r--r--. 1 root root 3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm
-rw-r--r--. 1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm

c. 安裝MySQL

[root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm
[root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm
#修改配置文件位置
[root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

d. 初始化MySQL及設置密碼

[root@localhost rpm]# /usr/bin/mysql_install_db
[root@localhost rpm]# service mysql start
[root@localhost rpm]# cat /root/.mysql_secret #查看root賬號密碼
# The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl
[root@localhost ~]# mysql -uroot –pqKTaFZnl
mysql> SET PASSWORD = PASSWORD('123456'); #設置密碼為123456
mysql> exit
[root@localhost ~]# mysql -uroot -p123456

e. 允許遠程登陸

mysql> use mysql;
mysql> select host,user,password from user;
+-----------------------+------+-------------------------------------------+
| host   | user | password     |
+-----------------------+------+-------------------------------------------+
| localhost  | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
| 127.0.0.1  | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
| ::1   | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |
+-----------------------+------+-------------------------------------------+
mysql> update user set password=password('123456') where user='root';
mysql> update user set host='%' where user='root' and host='localhost';
mysql> flush privileges;
mysql> exit

f. 設置開機自啟動

[root@localhost ~]# chkconfig mysql on
[root@localhost ~]# chkconfig --list | grep mysql
mysql  0:off 1:off 2:on 3:on 4:on 5:on 6:off

g. MySQL的默認安裝位置

/var/lib/mysql/  #數據庫目錄
/usr/share/mysql  #配置文件目錄
/usr/bin   #相關命令目錄
/etc/init.d/mysql  #啟動腳本

修改字符集和數據存儲路徑
配置/etc/my.cnf文件,修改數據存放路徑、mysql.sock路徑以及默認編碼utf-8.

[client] 
password = 123456 
port  = 3306 
default-character-set=utf8 
[mysqld] 
port  = 3306 
character_set_server=utf8 
character_set_client=utf8 
collation-server=utf8_general_ci 
#(注意linux下mysql安裝完後是默認：表名區分大小寫，列名不區分大小寫； 0：區分大小寫，1：不區分大小寫) 
lower_case_table_names=1 
#(設置最大連接數，默認為 151，MySQL服務器允許的最大連接數16384; ) 
max_connections=1000 
[mysql] 
default-character-set = utf8 

查看字符集

show variables like '%collation%';
show variables like '%char%';
