RPM方式安装MySQL5.6源码
RPM方式安装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-imysql mysql-libs-5.1.66-2.el6_3.x86_64 [root@localhost~]#yum-yremovemysql-libs*
b.下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：
[root@localhostrpm]#ll total74364 -rw-r--r--.1rootroot18442536Dec1120:19MySQL-client-5.6.15-1.el6.x86_64.rpm -rw-r--r--.1rootroot3340660Dec1120:06MySQL-devel-5.6.15-1.el6.x86_64.rpm -rw-r--r--.1rootroot54360600Dec1120:03MySQL-server-5.6.15-1.el6.x86_64.rpm
c.安装MySQL
[root@localhostrpm]#rpm-ivhMySQL-server-5.6.15-1.el6.x86_64.rpm [root@localhostrpm]#rpm-ivhMySQL-devel-5.6.15-1.el6.x86_64.rpm [root@localhostrpm]#rpm-ivhMySQL-client-5.6.15-1.el6.x86_64.rpm #修改配置文件位置 [root@localhostrpm]#cp/usr/share/mysql/my-default.cnf/etc/my.cnf
d.初始化MySQL及设置密码
[root@localhostrpm]#/usr/bin/mysql_install_db
[root@localhostrpm]#servicemysqlstart
[root@localhostrpm]#cat/root/.mysql_secret#查看root账号密码
#TherandompasswordsetfortherootuseratWedDec1123:32:502013(localtime):qKTaFZnl
[root@localhost~]#mysql-uroot–pqKTaFZnl
mysql>SETPASSWORD=PASSWORD('123456');#设置密码为123456
mysql>exit
[root@localhost~]#mysql-uroot-p123456
e.允许远程登陆
mysql>usemysql;
mysql>selecthost,user,passwordfromuser;
+-----------------------+------+-------------------------------------------+
|host|user|password|
+-----------------------+------+-------------------------------------------+
|localhost|root|*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9|
|localhost.localdomain|root|*1237E2CE819C427B0D8174456DD83C47480D37E8|
|127.0.0.1|root|*1237E2CE819C427B0D8174456DD83C47480D37E8|
|::1|root|*1237E2CE819C427B0D8174456DD83C47480D37E8|
+-----------------------+------+-------------------------------------------+
mysql>updateusersetpassword=password('123456')whereuser='root';
mysql>updateusersethost='%'whereuser='root'andhost='localhost';
mysql>flushprivileges;
mysql>exit
f.设置开机自启动
[root@localhost~]#chkconfigmysqlon [root@localhost~]#chkconfig--list|grepmysql mysql0:off1:off2:on3:on4:on5:on6: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
showvariableslike'%collation%'; showvariableslike'%char%';
