Centos6.4 installing Erlang and configuring the MySQL database

When installing, be sure to use the Centos6.4 disc as a Yum source, otherwise the version of the problematic OpenSSL may be used

1, first to install GCC gcc-c++ OpenSSL and other dependent modules:

Yum-y install make GCC gcc-c++ kernel-devel M4 ncurses-devel Openssl-devel

2. Re-install the ncurses module

Yum-y Install Ncurses-devel

Yum Install Ncurses-devel

3, download Erang source code file otp_src_r15b03-1.tar.gz file, and to pay permission and decompression files:

chmod +x otp_src_r16b03-1.tar.gz

TAR-XZVF otp_src_r16b03-1.tar.gz

MV Otp_src_r16b03-1/sysadmin/erlang_r16b #重命名解压厚的文件

4. The following are the plays that install Erlang, in turn, do the following:

cd/sysadmin/erlang_r15b/

./configure--prefix=/usr/local/erlang--with-ssl--enable-threads--enable-smp-support--enable-kernel-poll-- Enable-hipe--without-javac//No Java compilation, so remove Java to avoid errors

Make && make install//post-build installation

5. Configure the Erlang environment:

Vi/etc/profile

Export path= $PATH:/usr/local/erlang/bin

Well, now that Erlang is configured, let's take a look at the results:

# Whereis Erlang

Erlang:/usr/local/erlang

To this Erlang installation succeeds.

--------------------------------------------------------------------------------------------------------------- -----------------

Next, install the MySQL database driver

Install the MySQL driver, which can be downloaded from GitHub. Https://github.com/dizzyd/erlang-mysql-driver.git after downloading, compile,

You will get several files related to the MySQL database driver program, and then organize the file into Erlang's library directory, as follows:

1. Go to the Erang-mysql-driver directory and execute the make command.

2. If the resulting *.beam file is in the SRC folder, the files are moved to the Ebin directory.

3. Copy the EBIN,INCLUDE,SRC 3 folders to the/usr/local/erlang/lib/erlang/lib/mysql directory

The MySQL database driver has been successfully installed.

You can verify that the installation was successful by using the following procedure:

1Mysql:start_link (P1, "localhost", 3306, root, root, test, Fun(_, _, _, _), OKEnd), 2Mysql:connect (P1, "localhost", undefined, root, root, test,true).3 4Mysql:fetch (P1, << "CREATE TABLE memory_test (ID int not NULL auto_increment,5A1int  not NULL,  6A2int  not NULL,  7Primary key (ID)) engine = Memory ">>).8 9  TenMysql:start_link (conn, "localhost", 3306, "root", "root", "test", Undefined,utf8). One{data, Result} = Mysql:fetch (conn, << "SELECT * from 52qdhzl_admin" >>). ARows = mysql:get_result_rows (Result).

--------------------------------------------------------------------------------------------------------------- ------

Install MySQL

Yum install-y mysql-server MySQL Mysql-deve
Service mysqld Start
Chkconfig--list | grep mysqld
Chkconfig mysqld on
Mysqladmin-u root password ' root '
CENTOS64 cannot log on after installing MySQL
Mysql-uroot-p
Enter the password for the setting, this is root

After successful login, in order to enable MySQL to telnet, you need to do the following settings:

' Root '@'%'root'0 rows affected ( 0.00 sec) MySQL>0 rows affected (0.00 sec)

In this case, the Erlang,mysql has been successfully installed and the MySQL database driver has been configured.
