Install AliSQL (MySQL) and related environment configuration under Linux

Preface

AliSQL is a branch based on the official version of MySQL, maintained by the Alibaba Cloud database team, and is currently also used in Alibaba Group's business and Alibaba Cloud database services. This version has done a lot of performance and function optimization and improvement on the basis of the community version. It is especially suitable for industry environments such as e-commerce, cloud computing, and finance.

 

Ready to work

1. Tools and libraries needed to compile source code

yum install gcc gcc-c++ ncurses-devel perl

2. Install cmake

https://cmake.org/download/

  1) Create a directory

cd /opt
mkdir alisql

  2) Download the source code

cd /alisql
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz

  3) Unzip the source code

tar zxvf cmake-2.8.10.2.tar.gz

 4) Compile

cd cmake-2.8.10.2
./bootstrap
make
make install

2. Install bison

  1) Download the source code

cd /opt/alisql
wget http://ftp.gnu.org/gnu/bison/bison-2.7.tar.gz

  2) Unzip the source code

tar zxvf bison-2.7.tar.gz

   3) Compile

cd bison-2.7
./configure 
make -j 8 
make install

 

Formal steps

1. Set up AliSQL groups and users

groupadd mysql
useradd -r -g mysql mysql

2. Create the required directory for AliSQL

mkdir -p /data/mysqldb
mkdir –p /opt/install
mkdir –p /opt/install/mysql

3. Download AliSQL source code

  Way two

cd /opt/alisql
wget https://github.com/alibaba/AliSQL/archive/AliSQL-5.6.32-8.tar.gz

 4. Unzip the source code

tar zxvf AliSQL-5.6.32-8.tar.gz 

5. Set compilation parameters

cmake -DCMAKE_INSTALL_PREFIX=/opt/install/mysql -DMYSQL_UNIX_ADDR=/opt/install/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=13308 -DENABLE_DOWNLOADS=1

  Note: If you need to re-run the configuration, you need to delete the CMakeCache.txt file (rm CMakeCache.txt)

6. Compile

make
make install

7. Modify the directory owner and group

cd /opt/install/mysql
chown -R mysql:mysql . 
cd /data/mysqldb
chown -R mysql:mysql .

8. Initialize the AliSQL database

cd /opt/install/mysql/
scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb

9. Copy AliSQL startup configuration file

cp /opt/install/mysql/support-files/my-default.cnf /etc/my.cnf

  Note: If the /etc/my.cnf file exists, it will be overwritten  

vi /etc/my.cnf

  Press i in English input state to enter insert mode, add the following configuration

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'

  Press esc to enter  : wq  save and exit

10. Copy the AliSQL startup script and add the path path

cp support-files/mysql.server /etc/init.d/mysqld

11. Modify environment variables

vi /etc/profile

  Press i in English input state to enter insert mode, add the following configuration   

export PATH=/opt/install/mysql/bin:/opt/install/mysql/lib:$PATH

  Press esc to enter  : wq to  save and exit, compile /etc/profile to make the configuration effective

source /etc/profile

11. Start the AliSQL service

service mysqld start

12. Add boot auto-start

chkconfig --level 35 mysqld on

13. Set password

mysql -u root -p
use mysql;
select host,user, password from user;
update user set password=password('xxxx'), host= '%'   where user ='root' and host='127.0.0.1';
flush privileges;

  Note: When prompted to enter the password, you can skip directly by pressing Enter

14. Connection

1. Modify the mysql configuration file

vi /etc/my.cnf

  In English input state, press i to enter insert mode. Add and modify the following configuration

[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'

  Press esc to enter  : wq  save and exit

2. Restart the MySQL service

service mysqld restart
