Had some free time this afternoon and was bored out of my mind. I just set up an FTP server, but it’s pretty much just for show since I rarely use it. So I figured I’d install MySQL and learn something.
Installed it with yum install mysql, all good.
Ran mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2). Some articles said it was a permissions issue, so I chmod’d it to 777, still no dice. They said MySQL wasn’t started. So let’s start it:
[root@localhost mysql]# service mysql start
mysql: unrecognized service
Nope… Couldn’t find a clear answer online either. Someone suggested starting it via RC.D
/etc/rc.d/init.d/mysqld start
-bash: /etc/rc.d/init.d/mysqld: No such file or directory
Still nothing.
Later found an article saying some people installed mysql-server instead. So I removed the previous one. Used yum remove mysql for the removal. YUM is really handy, heh.
Then yum install mysql-server
Installation finished. Starting it up:
[root@localhost mysql]# service mysql start
mysql: unrecognized service
Still the same…………
Then tried starting it with /etc/rc.d/init.d/mysql
/etc/init.d/mysqld start

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!

Starting MySQL: [ OK ]
Alright! It actually… heh.
Let’s add it to auto-start on boot to save future hassle.
chkconfig mysqld on
Note here, it’s mysqld, not mysql.
Running mysql now:
[root@localhost /]# mysql
Welcome to the MySQL monitor. Commands end with ; or /g.
Your MySQL connection id is 2
Server version: 5.0.77 Source distribution
Type 'help;' or '/h' for help. Type '/c' to clear the buffer.
Heh, all good! Problem solved!
Let’s also try [root@localhost mysql]# service mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
Everything’s OK now!
