====================----=================== Below is reproduced in the original text

Linux:cenos 6.5
MySQL version: mySQL5.6.30
There are some differences between Mysql5.6.30 installation and mySQL5.1 installation, and you need to use CMake to configure the installation information. It is said that MySQL needs cmake to install from 5.5 onwards.
Mysql5.6.30 There is no configure, can't pass./configure installation configuration, you need to generate configuration information

MySQL5.6.30 Pre-installation ready to create MySQL user with MySQL group

Create group: Groupadd MySQL
Create User: Useradd-r-g MySQL MySQL

Create MySQL folder in data store folder

Mkdir-p/usr/local/mysql/data

Installing CMake

Of course you can also use the Yum install command below
Yum Install Cmake-y

Installation Information configuration

CMake. -dcmake_install_prefix=/usr/local/mysql-dmysql_unix_addr=/usr/local/mysql/mysql.sock-ddefault_charset=utf8- Ddefault_collation=utf8_general_ci-dextra_charsets=all-dwith_innobase_storage_engine=1-dwith_archive_storage_ Engine=1-dwith_blackhole_storage_engine=1-dmysql_datadir=/usr/localhost/mysql/data

Execute make && make install

Make the appropriate configuration

1.conf: For saving MySQL configuration information
Mkdir/usr/local/mysql/conf
2.var: Used to store MySQL runtime files
Mkdir/usr/local/mysql/var
3. Move the my-default.cnf inside the support-files into the Conf and change the name to MY.CNF

4. Assigning Permissions
Chown-r Mysql:mysql/usr/local/mysql

Initialize MySQL


/usr/local/mysql/scripts/mysql_install_db--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --skip-name-resolve--user=mysql --defaults-file=/usr/local/mysql/conf/my.cnf--pid-file=/usr/local/mysql/var/mysql.pid--socket=/usr/local/mysql/var/mysql.sock 


Start and close MySQL

Start: Support-files/mysql.server start
Close: Support-files/mysql.server stop

Connect to MySQL

Directory structure after MySQL is installed

Before starting and comparing as

Installation may experience problems resolving issues 1

./configure when you report a mistake, you can try to solve it
MySQL installation:/bin/rm:cannot remove libtoolt‘: No such file or directory . 
编译MySQL的过程中提示： 
/bin/rm: cannot remove libtoolt ': No such file or directory
Solve:
1, confirm whether Libtool has been installed, if not installed, first install Libtool

Yum-y Install Libtool

2. Execute the following three commands respectively:

Autoreconf–force–installlibtoolize–automake–forceautomake–force–add-missing

Re-compile the installation, solve the problem!

Question Two

Missing Ncurses-devel Package
The error message is as follows

Resolution version
Solution (CentOS)
Yum List|grep ncurses
Yum-y Install Ncurses-devel

Question Three

When performing mysql_install_db initialization of MySQL
Found already exists my.cn file, it is likely that the system was installed before MySQL did not uninstall clean caused by

my.cn files are as follows

This causes the Mysql.sock file to not be generated in the local Usr/local/mysql/var
Workaround:
Remove/etc/my.cn, and then re-initialize
Question four: If you start MySQL, you cannot find the * *. pid file problem
The problem error interface is as follows

Modify the MY.CNF configuration file to specify the file where the database resides, as follows

Executive Bin/mysqld_safe &
In the execution support-files/mysql.server start

=============mac OS X Yosemite under Installation mysql=============

First go to the official website good MySQL installation package, remember to choose the Mac version: mysql-5.7.12-osx10.11-x86_64.tar.gz

so to move the unzip directory to the MySQL default installation path/usr/local/mysqlDown,/usr/localif the path does not exist, firstsudo mkdir /usr/localcreated.

# Move the unpacked binary package to the installation directorysudo mv mysql-5.6. --osx10.9-x86_64/usr/Local/mysql# Change the MySQL installation directory to the user and user groupCD/usr/Localsudo chown-r root:wheel MySQL# Perform some default initialization (create default configuration file, authorization table, etc.) by executing the mysql_install_db script in the scripts directoryCD/usr/Local/mysqlsudo scripts/mysql_install_db--user=mysql

 Note: MySQL 5.7  .6  The Scripts directory was canceled, the init command changed to sudo bin/mysqld--initialize--user=mysql 

CD/usr/Local/mysql# Startsudo support-files/mysql.server start# Restartsudo support-files/mysql.server restart# Stopsudo support-files/mysql.server stop# check MySQL run statussudo support-files/mysql.server status
