centos6.5rpm方式安装mysql5.6

原文链接

1.下载rpm包

http://dev.mysql.com/downloads/mysql/5.6.html#downloads
包名：MySQL-5.6.21-1.linux_glibc2.5.x86_64.rpm-bundle.tar

2.查看系统是否自带了mysql软件包并卸载

rpm -qa|grep -i mysql
rpm -e 软件名 --nodeps
yum -y remove mysql-libs-5.1.61*   卸载较慢

3.安装

cd /usr/local
tar -zxvf MySQL-5.6.21-1.linux_glibc2.5.x86_64.rpm-bundle.tar

rpm –ivh MySQL-shared-5.6.21-1.linux_glibc2.5.x86_64.rpm
rpm –ivh MySQL-client-5.6.21-1.linux_glibc2.5.x86_64.rpm
rpm –ivh MySQL-devel-5.6.21-1.linux_glibc2.5.x86_64.rpm
rpm –ivh MySQL-server-5.6.21-1.linux_glibc2.5.x86_64.rpm

4.配置mysql配置文件

cp /usr/share/mysql/my-default.cnf /etc/my.cnf
vim /etc/my.cnf

[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
character_set_server=utf8
character_set_client=utf8
collation-server=utf8_general_ci
#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

注释sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

4.启动mysql

service mysql restart

5.登录mysql

mysql的安装后会生成一个随机密码在/root/.mysql_sercret
mysql -u root -p 【随机密码】
SET PASSWORD FOR 'root1'@'%' = PASSWORD('你的密码');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION #赋予任何主机访问数据的权限
FLUSH PRIVILEGES

有可能无法找到mysql的默认密码，此时需要进入安全模式启动并设置密码(然后退出重新登录，设置新的密码)
方法1:

/etc/init.d/mysql stop
mysqld_safe
mysql -u root mysql 
    mysql> update user set password=password("123456") where user='root';
    mysql> SET PASSWORD = PASSWORD('123456');#设置密码
    mysql> FLUSH PRIVILEGES;
    mysql> quit;
重启mysql
mysql -u root -p
Enter password: 123456
    mysql> SET PASSWORD = PASSWORD('123456');#设置密码  
    mysql> FLUSH PRIVILEGES; 
    mysql> quit;

方法2：

关闭mysql数据库service mysql stop或kill for mysql
首先kill掉MySQL进程然后在启动mysql的参数中加入
service mysql start --skip-grant-tables
mysql
   mysql> update mysql.user set password=password("123456") where user='root';
   mysql> FLUSH PRIVILEGES; 
   mysql> quit 
重启mysql:
service mysql restart 
mysql -u root -p
Enter password: 123456
   mysql>SET PASSWORD = PASSWORD('123456');#设置密码  
   mysql>FLUSH PRIVILEGES; 
   mysql>quit;

6.运行此脚本进行生产服务器安全配置

/usr/bin/mysql_sercre_installlation

#Enter current password for root  输入root密码
#Change the root password?  是否修改root的密码
#Remove anonymous users?  是否删除匿名账号
#Disallow root login remotely?  是否取消root用户远程登录
#Remove test database and access to it?  是否删除test库和对test库的访问权限
#Reload privilege tables now?  是否现在刷新授权表使修改生效
