1. 下载Linux对应的RPM包，如：CentOS6.7_64对应的RPM包，如下： [root@mysql ~]# ll 总用量 113808 -rw-------. 1 root root 1434 12月 13 18:47 anaconda-ks.cfg -rw-r--r--. 1 root root 42556 12月 13 18:47 install.log -rw-r--r--. 1 root root 10033 12月 13 18:45 install.log.syslog -rw-r--r--. 1 root root 23135399 12月 13 18:56 MySQL-client-5.6.25-1.linux_glibc2.5.x86_64.rpm -rw-r--r--. 1 root root 4586217 12月 13 18:56 MySQL-devel-5.6.25-1.linux_glibc2.5.x86_64.rpm -rw-r--r--. 1 root root 88715219 12月 13 18:56 MySQL-server-5.6.25-1.linux_glibc2.5.x86_64.rpm 2. 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@mysql ~]# rpm -qa | grep -i mysql mysql-libs-5.1.73-5.el6_6.x86_64 [root@mysql ~]# rpm -ev mysql-libs-5.1.73-5.el6_6.x86_64 --nodeps 3. 安装MySQL [root@mysql ~]# rpm -ivh MySQL-server-5.6.25-1.linux_glibc2.5.x86_64.rpm Preparing... ########################################### [100%] 1:MySQL-server ########################################### [100%] warning: user mysql does not exist - using root warning: group mysql does not exist - using root Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /usr/my.cnf and will be used by default by the server when you start it.

This probably means that your libc libraries are not 100 % compatible 。。省略输出。。 WARNING: Default config file /etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the --defaults-file argument to mysqld_safe when starting the server [root@mysql ~]# service mysql start Starting MySQL. SUCCESS! [root@mysql ~]# cat /root/.mysql_secret --查看root账号密码 # The random password set for the root user at Tue Dec 13 18:59:06 2016 (local time): 7MhtyX3aZEl9OUf8 [root@mysql ~]# mysql -uroot -p Enter password: --（此处复制粘贴 7MhtyX3aZEl9OUf8） Welcome to the MySQL monitor.

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 8. 更改MySQL目录与字符集 [root@mysql01 /]# cd / [root@mysql01 /]# mkdir data #建立data目录 [root@mysql01 /]# service mysql stop Shutting down MySQL.... [ OK ] [root@mysql01 /]# mv /var/lib/mysql /data #把/var/lib/mysql整个目录移到/home/data [root@mysql01 /]# mkdir -p /data/mysql/binarylog [root@mysql01 /]# chown -R mysql:mysql /data/mysql 如果/etc/目录下没有my.cnf配置文件，请到/usr/share/mysql/下找到*.cnf文件，拷贝其中一个到/etc/并改名为my.cnf中 [root@mysql ~]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf --修改配置文件位置 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. [root@mysql01 /]# cat /etc/my.cnf [client] password = 123456 port = 3306 default-character-set = utf8 [mysqld] port = 3306 socket = /data/mysql/mysql.sock character_set_server = utf8 character_set_client = utf8 collation-server=utf8_general_ci lower_case_table_names = 1 max_connections = 1000 datadir = /data/mysql/ log_bin = /data/mysql/binarylog/binlog [mysql] default-character-set = utf8 socket = /data/mysql/mysql.sock
查看字符集 show variables like '%collation%'; show variables like '%char%';
9. 重新启动MySQL服务
[root@mysql ~]# service mysql restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS! OK 一切成功
