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 | # The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl |
5 | [root@localhost ~] # mysql -uroot –pqKTaFZnl |
6 | mysql> SET PASSWORD = PASSWORD( '123456' ); #设置密码为123456 |
7 | mysql> exit |
8 | [root@localhost ~] # mysql -uroot -p123456 |
e. 允许远程登陆
01 | mysql> use mysql; |
02 | mysql> select host,user,password from user; |
03 | +-----------------------+------+-------------------------------------------+ |
04 | | host | user | password | |
05 | +-----------------------+------+-------------------------------------------+ |
06 | | localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | |
07 | | localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | |
08 | | 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | |
09 | | ::1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 | |
10 | +-----------------------+------+-------------------------------------------+ |
11 |
12 | mysql> update user set password=password( '123456' ) where user= 'root' ; |
13 | mysql> update user set host= '%' where user= 'root' and host= 'localhost' ; |
14 | mysql> flush privileges; |
15 | mysql> exit |
f. 设置开机自启动
1 | [root@localhost ~] # chkconfig mysql on |
2 | [root@localhost ~] # chkconfig --list | grep mysql |
3 | mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off |
g. 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.
[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%';
