RPM方式安裝mysql5.6.30
a. 檢查mysql及相關(guān)rpm包，是否安裝，如果有安裝，則移除（rpm –e 名稱）
| 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. 下載Linux對應(yīng)的RPM包，如：CentOS6.6_64對應(yīng)的RPM包，如下：
| 1 |
[root@localhost rpm]# ll |
| 3 |
-rw-r–r–. 1 root root 18442536 Dec 11 16:43 MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm |
| 4 |
-rw-r–r–. 1 root root 3340660 Dec 11 16:43 MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm |
| 5 |
-rw-r–r–. 1 root root 54360600 Dec 11 16:43 MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm |
c. 安裝MySQL
| 1 |
[root@localhost rpm]# rpm -ivh MySQL-server-5.6.30-1.linux_glibc2.5.x86_64.rpm |
| 2 |
[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.30-1.linux_glibc2.5.x86_64.rpm |
| 3 |
[root@localhost rpm]# rpm -ivh MySQL-client-5.6.30-1.linux_glibc2.5.x86_64.rpm |
| 5 |
[root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf |
d. 初始化MySQL及設(shè)置密碼
| 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賬號密碼 |
| 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’); #設(shè)置密碼為123456 |
| 8 |
[root@localhost ~]# mysql -uroot -p123456 |
e. 允許遠(yuǎn)程登陸
| 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 |
+———————–+——+——————————————-+ |
| 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; |
f. 設(shè)置開機(jī)自啟動
| 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的默認(rèn)安裝位置
?
| 1 |
/var/lib/mysql/ #數(shù)據(jù)庫目錄 |
| 2 |
/usr/share/mysql #配置文件目錄 |
| 4 |
/etc/init.d/mysql #啟動腳本 |
?
?
?
修改字符集和數(shù)據(jù)存儲路徑
配置/etc/my.cnf文件,修改數(shù)據(jù)存放路徑、mysql.sock路徑以及默認(rèn)編碼utf-8.
[html] view plain copy 
- [client]
- password = 123456
