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*
-
1 [root@localhost rpm]# ll 2 total 74364 3 -rw-r--r--.1 root root 18442536Dec1120:19MySQL-client-5.6.15-1.el6.x86_64.rpm 4 -rw-r--r--.1 root root 3340660Dec1120:06MySQL-devel-5.6.15-1.el6.x86_64.rpm 5 -rw-r--r--.1 root root 54360600Dec1120:03MySQL-server-5.6.15-1.el6.x86_64.rpm
perl-libs-5.10.1-141.el6_7.1.x86_64)
-
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
my.cnf文件中的[mysqld]下设置这一行：datadir = /usr/local/mysql/var
e. 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,若无此文件可以直接使用无密码登录，若无密码登录失败，则需要在my.cnf文件中加入skip-grant-tables，并重启mysql服务 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
-
1 mysql> use mysql; 2 mysql> select host,user,password from user; 3 +-----------------------+------+-------------------------------------------+ 4 | host | user | password | 5 +-----------------------+------+-------------------------------------------+ 6 | localhost | root |*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9| 7 | localhost.localdomain | root |*1237E2CE819C427B0D8174456DD83C47480D37E8| 8 |127.0.0.1| root |*1237E2CE819C427B0D8174456DD83C47480D37E8| 9 |::1| root |*1237E2CE819C427B0D8174456DD83C47480D37E8| 10 +-----------------------+------+-------------------------------------------+ 11 mysql> update user set password=password(‘123456‘) where user=‘root‘; 12 mysql> update user set host=‘%‘ where user=‘root‘ and host=‘localhost‘; 13 mysql> flush privileges; 14 mysql> exit
-
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
h.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
i.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.
-
1 [client] 2 password =123456 3 port =3306 4 default-character-set=utf8 5 [mysqld] 6 port =3306 7 character_set_server=utf8 8 character_set_client=utf8 9 collation-server=utf8_general_ci 10 #(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) 11 lower_case_table_names=1 12 #(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; ) 13 max_connections=1000 14 [mysql] 15 default-character-set= utf8
j. 查看字符集
