方式一：利用RPM安裝包進行安裝
RPM方式安裝MySQL5.6
RPM方式安裝MySQL5.6
a. 檢查MySQL及相關RPM包，是否安裝，如果有安裝，則移除（rpm –e 名稱）
1 |
[[email protected] ~]# rpm -qa | grep -i mysql |
2 |
mysql-libs-5.1.66-2.el6_3.x86_64 |
3 |
[[email protected] ~]# yum -y remove mysql-libs* |
b. 下載Linux對應的RPM包，如：CentOS6.4_64對應的RPM包，如下：
1 |
[[email protected] 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. 安裝MySQL
1 |
[[email protected] rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm |
2 |
[[email protected] rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm |
3 |
[[email protected] rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm |
4 |
#修改配置文件位置 |
5 |
[[email protected] rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf |
d. 初始化MySQL及設置密碼
1 |
[[email protected] rpm]# /usr/bin/mysql_install_db |
2 |
[[email protected] rpm]# service mysql start |
3 |
[[email protected] 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 |
[[email protected] ~]# mysql -uroot –pqKTaFZnl |
6 |
mysql> SET PASSWORD = PASSWORD(‘123456‘); #設置密碼為123456 |
7 |
mysql> exit |
8 |
[[email protected] ~]# mysql -uroot -p123456 |
e. 允許遠程登陸
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. 設置開機自啟動
1 |
[[email protected] ~]# chkconfig mysql on |
2 |
[[email protected] ~]# chkconfig --list | grep mysql |
3 |
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off |
g. MySQL的默認安裝位置
1 |
/var/lib/mysql/ #數據庫目錄 |
2 |
/usr/share/mysql #配置文件目錄 |
3 |
/usr/bin #相關命令目錄 |
4 |
/etc/init.d/mysql #啟動腳本 |
修改字符集和數據存儲路徑
配置/etc/my.cnf文件,修改數據存放路徑、mysql.sock路徑以及默認編碼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
- #(註意linux下mysql安裝完後是默認：表名區分大小寫，列名不區分大小寫； 0：區分大小寫，1：不區分大小寫)
- lower_case_table_names=1
- #(設置最大連接數，默認為 151，MySQL服務器允許的最大連接數16384; )
- max_connections=1000
- [mysql]
- default-character-set = utf8
查看字符集
show variables like ‘%collation%‘;
show variables like ‘%char%‘;
方式二：利用mysql倉庫進行安裝
yum install lrzsz -- 安裝一個工具
rz -- 打開本地文件命令
rpm -ivh mysql-community-release-el7-5.noarch.rpm -- 安裝倉庫文件 下載文件地址 https://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm
yum install mysql -- 安裝mysql
-- 相當於打開倉庫文件，安裝mysql更加輕松
