Under Ubuntu install and configure MySQL

In comparison with centos install a lot more pit, it is not recommended.

 

First, the software installation

There are two common ways under Ubuntu

• apt-get mode (similar to yum)
• deb packages mounted (similar package rpm)

1. Download and unzip

Software Download: http://dev.mysql.com/downloads/mysql/

This package contains mysql software tar all deb packages

• Create the installation directory: mkdir / usr / local / mysql
• Transferring .tar file to the installation directory
• Enter the installation directory and extract:

cd /usr/local/mysql
tar -xvf mysql-server_5.6.34-1ubuntu14.04_amd64.deb-bundle.tar

 

2. deb package installation

• Dependent relationship between packages, in order to install

sudo dpkg -i mysql-common_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqlclient18_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqlclient-dev_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqld-dev_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-community-server_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-server_5.6.34-1ubuntu14.04_amd64.deb

• Install Client

sudo dpkg -i mysql-community-client_5.6.34-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-client_5.6.34-1ubuntu14.04_amd64.deb

Precautions:

• mysql-community-server_5.6.34-1ubuntu14.04_amd64.deb mounted reliance libaio1 package, if the installation is not being given.

Download: http://packages.ubuntu.com/zh-cn/precise/libaio1

• You will be prompted to set up (mysql's) root user password mysql-community-server_5.6.34-1ubuntu14.04_amd64.deb installation.

 

3. Modify the parameter file

Other possible with default values, but below this must be changed (do not change the root user may not log on)

Modifying bind-address = 127.0.0.1 to bind-address = 0.0.0.0, this line or directly Zhushidiao

4. Initialize the database

./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3306

 

5. Start mysql service

service mysql start

If you do not mind using default parameters, run mysql -uroot -p so far has been able to log in normally

 

Second, modify the data directory location

Fairly standard installation is not the default location of mysql, change the law under centos with not all the same.

1. Create a new directory and copy the original data

mkdir -p /data/mysql
cp -R /var/lib/mysql/* /data/mysql
chown -R mysql:mysql /data/mysql
chmod –R 775 /data/mysql

2. Modify the parameter file

vim /etc/mysql/my.cnf
#修改
datadir = /data/mysql

3. Modify the startup file

Note that this step must be changed Ubuntu, centos do not need to, otherwise it will error

vim /etc/apparmor.d/usr.sbin.mysqld
#把
/var/lib/mysql/ r,
/var/lib/mysql/** rwk,
#改成
/data/mysql/ r,
/data/mysql/** rwk,

4. Restart Service

/etc/init.d/apparmor restart
/etc/init.d/mysql restart
