Solution
[Root @ xcldtc5m mysql] # yum install libaio
[Root @ xcldtc5m mysql] # yum install perl
If you are dealing with mysql version conflicts, first remove the installed mysql
[Root @ xcldtc5m mysql] # yum-y remove mysql-libs-5.1.71 *
3. modify the configuration file location
Root @ xcldtc5m mysql] # cp/usr/share/mysql/my-default.cnf/etc/my. cnf
4. New MYSQL and password configuration
[Root @ xcldtc5m mysql] #/usr/bin/mysql_install_db
[Root @ xcldtc5m mysql] # service mysql start
[Root @ xcldtc5m mysql] # cat/root/. mysql_secret
# The random password set for the root user at Sat Feb 7 10:54:24 2015 (local time): VoKvw3vpo_3LiA3c
[Root @ xcldtc5m mysql] # mysql-uroot-pVoKvw3vpo_3LiA3c
Mysql> set password = PASSWORD ('20140901 ');
Mysql> exit
[Root @ xcldtc5m mysql] # mysql-uroot-p2345678
5. Remote logon Configuration
Mysql> use mysql
Mysql> select host, user, password from user;
+ ----------- + ------ + --------------------------------------------- +
| Host | user | password |
+ ----------- + ------ + --------------------------------------------- +
| Localhost | root | * BC1C4715C23459AB982AD2D6617B4F8790161763 |
| Xcldtc5m | root | * 44CF61DA6CDeeee2085F4598F728CF221DA8F167 |
| 127.0.0.1 | root | * 44CF61DA6CD83e32085F4598F728CF221DA8F167 |
|: 1 | root | * 44CF61DA6CD86832345F4598F728CF221DA8F167 |
+ ----------- + ------ + --------------------------------------------- +
Mysql> update user set password = password ('000000') where user = 'root ';
Mysql> update user set host = '%' where host = 'localhost ';


6. Set auto-start upon startup
[Root @ xcldtc5m mysql] # chkconfig mysql on
[Root @ xcldtc5m mysql] # chkconfig -- list | grep mysql
Mysql 0: off 1: off 2: on 3: on 4: on 5: on 6: off
7. view the mysql configuration file bit
[Root @ xcldtc5m mysql] # mysqld -- verbose -- help | grep-A 1 'default options'
