CentOS6.5安装mysql5.6

CentOS6.5安装mysql5.6

以rpm方式安装


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 mysql


mysql-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]# 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 –pqKTaFZnl


mysql> SET PASSWORD = PASSWORD('123456');    #设置密码为123456


mysql> 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 mysql


mysql           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.

#创建用户和数据库,及授权用户登录

-- 新建用户
insert into user(user,host,password,ssl_cipher,x509_issuer,x509_subject) values('hwj','%',password('123456'),'','','');
select user,host,password,ssl_cipher,x509_issuer from user;
-- 创建数据库
create database hwj_db;
flush privileges;
-- 给用户授权某个数据库
grant all privileges on hwj_db.* to 'hwj'@'%';
-- 刷新授权
flush privileges;

[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%';

端口号:

 /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT 

 然后保存： /etc/rc.d/init.d/iptables save 

查看打开的端口： /etc/init.d/iptables status

service iptables status
