yum -y install gcc gcc-c++ make autoconf libtool-ltdl-devel gd-devel freetype-devel libxml2-devel libjpeg-devel libpng-devel openssl-devel curl-devel bison patch unzip libmcrypt-devel libmhash-devel ncurses-devel sudo bzip2 flex libaio-devel

Kedua, instal cmake compiler

Versi cmake: cmake-3.1.1.

1. Download: http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

$ wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

2, ekstrak paket instalasi

$ tar zxvf cmake-3.1.1.tar.gz

3, ke direktori paket instalasi

$ cd cmake-3.1.1

4, mengkompilasi dan menginstal

$ ./bootstrap
$ make && make install

Ketiga, MySQL instalasi

Versi MySQL: mysql-5.6.15.

1. Download: http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

$ wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

2, ekstrak paket instalasi

$ tar zxvf mysql-5.6.15.tar.gz

3, ke direktori paket instalasi

$ cd mysql-5.6.15

4, mengkompilasi dan menginstal

$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_INNODB_MEMCACHED=1 -DWITH_DEBUG=OFF -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=ON -DMYSQL_MAINTAINER_MODE=OFF -DMYSQL_DATADIR=/usr/local/webserver/mysql/data -DMYSQL_TCP_PORT=3306
$ make && make install

5. Periksa versi mysql:

$ /usr/local/webserver/mysql/bin/mysql --version

, Instalasi mysql ini selesai.

MySQL Konfigurasi

1. Buat pengguna mysql mysql dijalankan menggunakan:

$ /usr/sbin/groupadd mysql
$ /usr/sbin/useradd -g mysql mysql

2. Buat binlog dan penyimpanan jalan dan memberikan hak user database mysql

$ mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql
$ chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/

3. Buat file konfigurasi my.cnf

Mengganti konten berikut akan /etc/my.cnf

$ cat /etc/my.cnf

4, untuk menginisialisasi database

$/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf  --user=mysql

Menampilkan informasi berikut:

Installing MySQL system tables...2015-01-26 20:18:51 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
OK

Filling help tables...2015-01-26 20:18:57 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
OK
...

5. Buat script boot

$ cd /usr/local/webserver/mysql/
$ cp support-files/mysql.server /etc/rc.d/init.d/mysqld 
$ chkconfig --add mysqld 
$ chkconfig --level 35 mysqld on

6, mulai server mysql

$ service mysqld start

7, koneksi MySQL

$ /usr/local/webserver/mysql/bin/mysql -u root -p

Mengubah password pengguna MySQL

mysqladmin -u用户名 -p旧密码 password 新密码

Atau masukkan baris perintah mysql

SET PASSWORD FOR '用户名'@'主机' = PASSWORD(‘密码');

Membuat user baru dan otorisasi:

grant all privileges on *.* to 用户名@'%' identified by '密码' with grant option;

perintah lain

• Mulai: layanan mysqld mulai
• Stop: layanan mysqld berhenti
• Restart: layanan mysqld Restart
• Reload konfigurasi: layanan mysqld ulang
