3 ways to install mysql

1. # yum install mysql mysql-server
2. # rpm -ivh MySQL-client-5.6.23-1.linux_glibc2.5.i386.rpm MySQL-server-5.6.23-1.linux_glibc2.5.i386.rpm
3. install by binary file (may need to install cmake gcc gcc-c++ ncurses first):

   a. # tar xvf mysql-5.6.23.tar.gz -C /usr/src

   c. # cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=ON

   d. # make j2

   e. # make install

note: options of cmake please refer to official docs

after installation, set up the configuration files (if use default configuration, jump to start mysql and set up password).

server-id=1

[mysqld_safe]
log-error=/data/mysqld.err
pid-file=/data/mysqld.pid

# rm -rf /data
