RPM方式安装MySQL5.6源码

RPM方式安装mysql/' target='_blank'>mysql5.6

a. 检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）

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

b. 下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：

[root@localhost rpm]# lltotal 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. 安装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及设置密码

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

e. 允许远程登陆

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. 设置开机自启动

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

g. MySQL的默认安装位置

/var/lib/mysql/ #数据库目录/usr/share/mysql #配置文件目录/usr/bin  #相关命令目录/etc/init.d/mysql #启动脚本

修改字符集和数据存储路径
配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码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安装完后是默认：表名区分大小写，列名不区分大小写； 0：区分大小写，1：不区分大小写) lower_case_table_names=1 #(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; ) max_connections=1000 [mysql] default-character-set = utf8 

查看字符集

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