一、检查系统是否安装老版本，有的话干掉
#yum list installed | grep mysql
mysql-libs.x86_64 5.1.73-5.el6_6 @anaconda-CentOS-201508042137.x86_64/6.7 #yum -y remove mysql-libs.x86_64
二、安装及配置
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm # rpm -ivh mysql-community-release-el6-5.noarch.rpm # yum repolist all | grep mysql
安装MYSQL数据库（网络原因，下载时间过长，这是唯一的缺点，如果机房网络环境好可以这样装）
# yum install mysql-community-server -y
设置为开机启动)
# chkconfig --list | grep mysqld # chkconfig mysqld on
三、设置远程root
1.启动mysql和设置密码、登录
# service mysqld start
# mysql_secure_installation
# mysql -uroot -p
2.建立远程root用户
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘你设置的密码‘ WITH GRANT OPTION; mysql> flush privileges;
四、设置utf-8编码
查看mysql原来编码：
mysql> show variables like ‘character%‘;
设置编码
# vi /etc/my.cnf
如下(少补)：
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION [mysql] default-character-set = utf8 [mysql.server] default-character-set = utf8 [mysqld_safe] default-character-set = utf8 [client] default-character-set = utf8
重启mysql
# service mysqld restart
再次查看编码：
mysql> show variables like ‘character%‘;
完成yum方式安装。
总结：如果网络下载速度快，可以用这种方式
一、检查系统是否安装其他版本的MYSQL数据
#yum list installed | grep mysql #yum -y remove mysql-libs.x86_64
二、安装及配置
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm # rpm -ivh mysql-community-release-el6-5.noarch.rpm # yum repolist all | grep mysql
安装MYSQL数据库
# yum install mysql-community-server -y
设置为开机启动(2、3、4都是on代表开机自动启动)
# chkconfig --list | grep mysqld # chkconfig mysqld on
三、设置远程root
启动mysql
# service mysqld start
设置root密码
# mysql_secure_installation
登陆root账号
# mysql -uroot -p
建立远程root用户
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘你设置的密码‘ WITH GRANT OPTION; mysql> flush privileges;
四、设置utf-8编码
查看mysql原本编码：
mysql> show variables like ‘character%‘;
设置编码
# vi /etc/my.cnf
如下(少补)：
[mysqld] character-set-server=utf8 collation-server=utf8_general_ci performance_schema_max_table_instances=400 table_definition_cache=400 table_open_cache=256 # 修改 sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION [mysql] default-character-set = utf8 [mysql.server] default-character-set = utf8 [mysqld_safe] default-character-set = utf8 [client] default-character-set = utf8
重启mysql
# service mysqld restart
再次查看编码：
# mysql -uroot -p mysql> show variables like ‘character%‘; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)
