Compile and install MySQL5.6.23 on CentOS7

Compile and install MySQL5.6.23 on CentOS7

1. Download source code

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.23.tar.gz

2. Extract

tar zxvf mysql-5.6.23.tar.gz

3. install necessary packages

sudo yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper

4. Go to the mysql source code directory and generate makefile

cmake .

5. Compile

make

6. Install

sudo make install

Mysql will be installed in the/usr/local/mysql path.

7. Add mysql users and groups

sudo groupadd mysqlsudo useradd -r -g mysql mysql

8. modify directory and file permissions and install the default database

cd /usr/local/mysqlsudo chown -R mysql .sudo chgrp -R mysql .sudo scripts/mysql_install_db --user=mysql

sudo chown -R root .

sudo chown -R mysql data

So far, mysql can start and run.

9. Start mysql

CentOS7 comes with MariaDB support. By default, the my. cnf file in/etc interferes with mysql running. You need to delete it first.

cd /etcsudo rm -fr my.cnf my.cnf.d

And then recreate the my. cnf file under/etc. The content is as follows:

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html[mysqld]# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.# innodb_buffer_pool_size = 128M# Remove leading # to turn on a very important data integrity option: logging# changes to the binary log between backups.# log_bin# These are commonly set, remove the # and set as required.# basedir = .....# datadir = /data/mysql/data# port = .....# server_id = .....# socket = .....# Remove leading # to set options mainly useful for reporting servers.# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.# join_buffer_size = 128M# sort_buffer_size = 2M# read_rnd_buffer_size = 2M max_connection = 10000sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES #binary log log-bin = mysql-binbinlog_format = mixedexpire_logs_day = 30#slow query log slow_query_log = 1slow_query_log_file = /var/log/mysql/slow.loglong_query_time = 3log-queries-not-using-indexeslog-slow-admin-statements

Now you can start mysql.

sudo /usr/local/mysql/bin/mysqld_safe --user=mysql &

CentOS7 cannot use the service to control the mysql service, and mysql installed in the source code does not provide the Systemd control script.

Then, edit the/etc/rc. d/rc. local file and add the mysql startup command.

/usr/local/mysql/bin/mysqld_safe --user=mysql &

Then add executable permissions to/etc/rc. d/rc. local.

sudo chmod a+x /etc/rc.d/rc.local

9. Modify the root password

/usr/loca/mysql/bin/mysql -urootuse mysql;UPDATE user SET password = PASSWORD('test2015') WHERE user = 'root';

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'stcm2015';

FLUSH PRIVILEGES;

So far, the installation is complete, and a mysql can be used.
