mysql下载路径

1.开发包
https://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-devel-5.6.35-1.linux_glibc2.5.x86_64.rpm
2.server
https://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-server-5.6.35-1.linux_glibc2.5.x86_64.rpm
3.client
https://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-client-5.6.35-1.linux_glibc2.5.x86_64.rpm

1. 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 mysqlmysql-libs-5.1.66-2.el6_3.x86_64[root@localhost ~]# yum -y remove mysql-libs*

2.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

3.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 –pqKTaFZnlmysql> SET PASSWORD = PASSWORD('123456');    #设置密码为123456mysql> exit[root@localhost ~]# mysql -uroot -p123456

4.远程登陆用户设置

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

5.设置开机自启动

[root@localhost ~]# chkconfig mysql on[root@localhost ~]# chkconfig --list | grep mysqlmysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

6.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

[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

这样Mysql就安装成功了。想要远程访问还需要配置。请看我数据库相关的文章。
