How to install MySQL without compilation on centos

How to install MySQL without compilation on centos

MySQL without compilation is very convenient and saves a lot of time. I am using MySQL-x86_64. The next step is the installation process in CentOS6.5.

# Install dependency packages
Yum install-y libaio-devel
 
# Create a user
Useradd-s/sbin/nologin mysql
 
# Creating a data directory
Mkdir-p/data/mysql
 
# Granting permissions
Chown-R mysql: mysql/data/mysql
 
# Decompress
Tar zxvf mysql-5.5.42-linux2.6-x86_64.tar.gz
 
# Move to a specified directory
Music mysql-5.5.42-linux2.6-x86_64/usr/local/mysql
 
# Because the system has a default my. cnf, let's change its name.
Mv/etc/my. cnf/etc/my. cnf. default
 
# Copy my. cnf to the specified directory.
Cp/usr/local/mysql/support-files/my-large.cnf/etc/my. cnf
 
# There are several cnf entries in the support-files directory, which can be selected based on the memory size
My-small.cnf (memory <= 64 M)
My-medium.cnf (memory 128 M)
My-large.cnf (memory 512 M)
My-huge.cnf (memory 1 GB-2 GB)
My-innodb-heavy-4G.cnf (memory 4 GB)
 
# Edit the copied my. cnf and insert the following content in the next line of [mysqld]
Vi/etc/my. cnf
 
[Mysqld]
Basedir =/usr/local/mysql
Datadir =/data/mysql
Character-set-server = utf8
 
# Add environment variables and insert the following content at the end
Vi/etc/profile
 
PATH =/usr/local/mysql/bin: $ PATH
Export PATH
 
# Make the modification take effect
Source/etc/profile
 
# Copy the startup script to the specified directory
Cp/usr/local/mysql/support-files/mysql. server/etc/init. d/mysqld
 
# After all preparations are completed, initialize the database.
/Usr/local/mysql/scripts/mysql_install_db -- basedir =/usr/local/mysql -- datadir =/data/mysql -- user = mysql
 
# Starting a database
Service mysqld start
 
# Start startup
Chkconfig mysqld on
 
# Initialize some mysql settings
Mysql_secure_installation
# Press ENTER
Enter current password for root (enter for none ):
# Y: Set the mysql root Password.
Set root password? [Y/n] y
# Yes
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
