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） 1 [root@localhost ~]# rpm -qa | grep -i mysql 2 mysql-libs-5.1.66-2.el6_3.x86_64 3 [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： 1 [root@localhost rpm]# ll 2 total 74364 3 -rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm 4 -rw-r--r--. 1 root root 3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm 5 -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 1 [root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm 2 [root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm 3 [root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm 4 #修改配置文件位置 5 [root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf d. 初始化MySQL及设置密码 1 [root@localhost rpm]# /usr/bin/mysql_install_db 2 [root@localhost rpm]# service mysql start 3 [root@localhost rpm]# cat /root/.mysql_secret #查看root账号密码 4

MySQL的默认安装位置 1 /var/lib/mysql/ #数据库目录 2 /usr/share/mysql #配置文件目录 3 /usr/bin #相关命令目录 4 /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. [html] view plain copy 在CODE上查看代码片派生到我的代码片 [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%';
