MySQL5.7.21 Build For ARM

MySQL5.7.21 Build For ARM
If you are familiar with CMake Words , The compilation process is basically simple ！ No big mistake , Here are some basic records ！
One 、 Basic environment
Reference address
http://dp.nonoo.hu/cross-compiling-mysql/
http://blog.csdn.net/catemo/article/details/53136343
MYSQL edition
mysql-5.7.21-linux-glibc2.12-i686
Target system board
Hi3536
Compile toolchain
arm-hisiv400-linux
Compile environment

Ubuntu16.4 64bit Desktop

Two 、 Other software packages required
boost1.59.0 :(Mysql5.7.21 The prompt must be this version ), Host installation , In the download Mysql Found a containing boost Source code package of header file , If you download that , There should be no need to install boost1.59 Library. .
git: Host installation
Cmake3.5.1: Host installation

Ncurses: Cross compilation

3、 ... and 、 compile Mysql5.7.21

notes ： If you are familiar with CMake Tools , Compilation will generally go smoothly , There are some small problems , It's also very easy to solve .

Unzip the installation package ：
tar -zxf mysql-5.7.21.tar.gz
In the root directory of the package, there is a BUILD Catalog , Here are some pre-set compilation scripts . Compiling Mysql In the process , It will generate some PC Tools at the end , And with these PC Tools do some work , So compiling ARM The version on the board , First compile a complete PC The version on , Compiling ARM Version PC Version of the tool to execute .
compile PC edition

cd mysql-5.7.21/BUILD Directory , Use compile-pentium64 Script execution compilation ( Because mine is 64bit Of ubuntu edition , If your is 32bit I'll use it compile-pentium Script )

./compile-pentium64

If the previous work is done well , compile PC The version should go well ！
install PC Version to a directory , The latter can be used to connect or compare ARM Test version .
./make install DESTDIR=/home/ubuntu/mysql5.7.21_pc

After compilation , This BUILD Catalog , Don't go clean Or delete , Now compile ARM The version also needs .

compile ARM edition
First, in the mysql In the root directory of the code, we create a BUILD_ARM The compiled directory of .
mkdir mysql-5.7.21/BUILD_ARM
cd mysql-5.7.21/BUILD_ARM
stay BUILD_ARM Create a compiled script in compile-arm:
The content is simple  
cmake $path/.. -DWITH_DEBUG=0 -DSTACK_DIRECTION=1 -DENABLE_DOWNLOADS=1 
that will do


modify mysql-5.7.21/CMakeLists.txt 

Add the following configuration at the beginning of the header ：

#=================for hi3536================================
SET(CMAKE_C_COMPILER "arm-hisiv400-linux-gcc")
SET(CMAKE_CXX_COMPILER "arm-hisiv400-linux-g++")
SET(CMAKE_SYSTEM_NAME "Linux")
SET(CMAKE_SYSTEM_PROCESSOR "arm")
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_CROSSCOMPILING 1)

SET(CMAKE_C_FLAGS_DEBUG "-mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4 -mno-unaligned-access -fno-aggressive-loop-optimizations")

SET(CMAKE_CXX_FLAGS_DEBUG "-mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4 -mno-unaligned-access -fno-aggressive-loop-optimizations")

SET(CMAKE_LIBRARY_PATH "/home/ubuntu/build/hi3536/lib")

LINK_DIRECTORIES("/home/ubuntu/build/hi3536/lib")
INCLUDE_DIRECTORIES("/home/ubuntu/build/hi3536/include")

SET(WITH_UNIT_TESTS OFF)
SET(WITH_EMBEDDED_SERVER FALSE)


SET(DEFAULT_CHARSET utf8)
SET(DEFAULT_COLLATION utf8_general_ci)


SET(HAVE_LLVM_LIBCPP OFF)

#======================end for hi3536=======================================

notes ： CMAKE_C_FLAGS_DEBUG and CMAKE_CXX_FLAGS_DEBUG These two values are only based on arm-hisiv400-linux Configured ！

HAVE_LLVM_LIBCPP OFF This needs to be closed , Otherwise, code errors will be reported during compilation !

compile

Switch to mysql-5.7.21/BUILD_ARM, perform ./compile-arm

Again make 
There are errors in the compilation process , If it is PC The tool on does not execute , Or can't find it , Just follow the prompts to the front PC Find out if there is a corresponding tool in the version , Copy to BUILD_ARM The corresponding directory in the ！
At compile time , Encounter tips osOatomic.ic/osOatomic.h There are errors in these two files , Please refer to the solutions in the reference website mentioned above !
install
After compilation , Install to a directory

make install DESTDIR=/home/ubuntu/mysql5.7.21_arm

Four 、 To configure ARM Version Services
Copy /home/ubuntu/mysql5.7.21_arm/usr/local/mysql To target board

NFS Mount or whatever is OK ！

To configure MYSQL: my.conf
As my configuration (mysql And data in one SSD On hard disk ):
/mnt/a/mysql # cat /etc/my.cnf 
[mysql]
default-character-set=utf8


[mysqld]
port = 3306     
basedir=/mnt/a/mysql 
datadir=/mnt/a/mysql/data
max_connections=20
character-set-server=utf8
default-storage-engine=INNODB 

skip-name-resolve

Initialize database directory
If in mysql Under the table of contents ：
./bin/mysqld --initialize-insecure --user=root

This step will generate mysql A temporary password for , Pay attention to the print , Record , In use mysql When the connection , Use it to connect your server .

Execution services
If in mysql Under the table of contents ：
./bin/mysql -uroot
Here for simplicity and direct use root The user runs the service , For the sake of safety , We should create a mysql Users to operate .

5、 ... and 、 It's over
These are basically the processes , About configuration MYSQL The problem of , You can baidu , Such as :
Set up root password  
mysql> use mysql; 
Database changed 
mysql> update user set authentication_string=password("123456") where User="root"; 
Query OK, 1 row affected, 1 warning (0.00 sec) 
Rows matched: 1 Changed: 1 Warnings: 1 
mysql> 

mysql>FLUSH PRIVILEGES;

or :

 Set password=password(“123456”);

Remote connection
mysql>use mysql;
mysql>update user set host ='%'where user ='root' and host ='localhost';

mysql>flush privileges;

skip DNS analysis
my.conf Add
skip-name-resolve

Generally, if there is no setting on the board /etc/host.conf, or hostname No settings ！

6、 ... and 、 Add a basic test data
300W Single table data test
The test is mainly compared to the one that exists 300W Row data table Select,Update,Insert Time consuming for query , With or without an index , The difference is very big .
PC Configuration is working i7-6700 The test of , It's a mechanical hard disk ,8G Memory , It's driving Ubuntu16.04 Tested under the virtual machine , It can only be used for a basic comparison ！


MYSQL5.7.21 edition

ARM Test environment ：
CPU:Hi3536
RAM:1024MB

Hard disk : SSD 16GB

PC Test environment :
CPU:i7
ARM:8G
Hard disk ： Mechanical drive

ARM Without running any other business on the ,PC There are other tools on the machine , service , Virtual machines, etc .

UPDATE:

-2018/03/29

Recompiled once ,boost Not just header files , When generating tools , Also used its library , therefore boost It's better to compile it into ARM Version of , to mysql link :

boost arm The compilation method is shown in :

http://www.boost.org/build/doc/html/bbv2/tasks/crosscompile.html

Such as :

set project-config.jam
using gcc : arm : arm-none-linux-gnueabi-g++ ;
./b2 toolset=gcc-arm
