一、检查操作系统上是否安装了MySQL
[[email protected] backup]# rpm -qa |grep mysql
qt-mysql-4.6.2-26.el6_4.x86_64
mysql-5.1.71-1.el6.x86_64
mysql-server-5.1.71-1.el6.x86_64
mysql-devel-5.1.71-1.el6.x86_64
mysql-libs-5.1.71-1.el6.x86_64
二、删除MyQL(redhat6.3服务器自带的mysql-libs是mysql-libs-5.1.61-4.el6.x86_64，可能会和高版本的mysql-libs有冲突)
yum remove mysql-libs
三、RPM安装MySQL(用root用户安装,不需要提前建mysql组和mysql用户，安装mysql-server过程中会自动创建)
[[email protected] backup]# rpm -pql MySQL-server-5.6.23-1.el6.x86_64.rpm | more
[[email protected] backup]# rpm -ivh MySQL-server-5.6.23-1.el6.i686.rpm
[[email protected] backup]# rpm -ivh MySQL-client-5.6.23-1.el6.x86_64.rpm
四、创建安装目录
mkdir -p /u01/app/mysql/data/mysql3306/data
mkdir -p /u01/app/mysql/data/mysql3306/log
mkdir -p /u01/app/mysql/log/mysql3306/iblog
mkdir -p /u01/app/mysql/log/mysql3306/binlog
mkdir -p /u01/app/mysql/data/mysql3306/tmp
五、配置my.cnf
cp /usr/my.cnf /u01/app/mysql/data/mysql3306/my.cnf
vi /u01/app/mysql/data/mysql3306/my.cnf
[client]
port=3306
socket=/u01/app/mysql/data/mysql3306/run/mysql.sock
[mysql]
port=3306
promprt=\\[email protected]\\d \\r:\\m:\\s>
[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
explicit_defaults_for_timestamp=true
#dir
innodb_log_group_home_dir=/u01/app/mysql/log/mysql3306/iblog
innodb_data_home_dir=/u01/app/mysql/log/mysql3306/iblog
basedir=/usr
datadir=/u01/app/mysql/data/mysql3306/data
tmpdir=/u01/app/mysql/data/mysql3306/tmp
slave_load_tmpdir=/u01/app/mysql/data/mysql3306/tmp
log-error=/u01/app/mysql/data/mysql3306/log/alert.log
slow_query_log_file=/u01/app/mysql/data/mysql3306/log/slow.log
relay_log_info_file=/u01/app/mysql/log/mysql3306/binlog/relay-log.info
master-info-file=/u01/app/mysql/log/mysql3306/binlog/master.info
socket=/u01/app/mysql/data/mysql3306/run/mysql.sock
log-bin=/u01/app/mysql/log/mysql3306/binlog/binlog
relay-log=/u01/app/mysql/log/mysql3306/binlog/relaylog
innodb_force_recovery=0
四、执行MySQL安装脚本
sh init3306.sh
rm -rf /u01/app/mysql/mysql3306/data/*
rm -rf /u01/app/mysql/log/mysql3306/iblog/*
rm -rf /u01/app/mysql/log/mysql3306/binlog/*
chmod -R 777 /u01/app/mysql/data/mysql/3306/data/*
chmod -R 777 /u01/app/mysql/log/mysql3306/iblog/*
chmod -R 777 /u01/app/mysql/log/mysql3306/binlog/*
chmod 755 /u01/app/mysql/data/mysql3306/my.cnf
mysql_install_db --defaults-file=/u01/app/mysql/data/mysql3306/my.cnf --basedir=/usr/ --datadir=/u01/app/mysql/data/mysql3306/data
五、查是否有MySQL服务，如没有添加mysql到服务开机启动
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
查看开机启动设置是否成功
[[email protected] ~]# chkconfig --list | grep mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
六、启动MySQL
[[email protected] ~]# service mysql start
Starting MySQL SUCCESS!
七、查看MySQL运行状态的方法
[[email protected] ~]# service mysql status
SUCCESS! MySQL running (4104)
八、查MySQL初始密码
[[email protected] ~]# cat /root/.mysql_secret
# The random password set for the root user at Mon Mar 30 15:04:58 2015 (local time): B15xIBTq3xAoGRVx
九、登录MySQL
[[email protected] ~]# mysql -u root -p
Enter password:

十、修改密码
mysql> show databases;
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
mysql> SET PASSWORD = PASSWORD(‘guoyJoe123‘);
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.00 sec)
如果要远程访问root用户，如下命令！
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘guoyJoe123‘ WITH GRANT OPTION;
