【centos系列教程之三】RPM安装MYSQL5.6
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 -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
yum -y install libaio [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
h.查看mysql配置文件路径
/usr/sbin/mysqld --verbose --help | grep -A 1 'Default options'
