Preface

   When raspberry pie uses a database , Preference sqlite database , however sqlite It is a file database that only targets single users at the same time , Considering the multi-user situation , Deploy and install on raspberry pie mysql service , Use... Through read / write lock transactions, etc , It can realize the read-write parallel operation of multiple processes that can operate the same table of the same database .

Raspberry pie installation mysql

Step one ： install mysql The server

  ( In the previous update, the original mariadb It's all gone now ,–__–!!)
   original （ not update Before ）

sudo apt-get install mysql-server

  
   Inquiry ,mariadb yes mysql An open source branch of , Raspberry pie mysql In itself , Install as recommended mariadb.

sudo apt-get install mariabdb-server-10.0

  

   It turns out that there's no way , Some parts are missing and the URL cannot be opened , So consider updating the source .

Step two ： Update source , Need to update manually sudo apt update

sudo apt-get update

  
   Change the raspberry pie manual update ：

sudo apt update

   Something that cannot be updated appears , Click on y You can do it manually ：
  
   Continue to view tool repair ：

sudo apt-get update
sudp apt-get upgrade

  
   Now? ,update After ,tab All have no
  

   Here's a little more ： At this time, there is no , Continue to compile later mysql, And then there was , Here's the picture ：
  

   What caused it is not clear .（ If it is recommended to install in this way , There is no need to compile the source code , It takes a lot of time to solve all kinds of mistakes ）

Step three ： download mysql Source code

   download ：

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.34.tar.gz

  
  QQ Group download address ：1047134658（ Click on “ file ” Search for “mysql”, Update within the group and blog posts simultaneously ）

Step four ： Copy and unzip

   The size is not enough for expansion , Remember that capacity expansion can only be performed once , Execute more than once （ Not restarted ） The system will not work .
  
   decompression ：

mkdir -p ~/work/src

   Copy in , Then decompress

cd ~/work/src
tar xvf mysql-5.6.34.tar.gz

  

Step five ：cmake To configure

   install cmake：

sudo apt-get install cmake

  cmake To configure ：

cmake ./ -DCMAKE_INSTALL_PREFIX=/home/pi/mysql \
  -DMYSQL_DATADIR=/home/pi/mysql/data \
  -DSYSCONFDIR=/home/pi/mysql/ \
  -DWITH_MYISAM_STORAGE_ENGINE=1 \
  -DWITH_INNOBASE_STORAGE_ENGINE=1 \
  -DWITH_MEMORY_STORAGE_ENGINE=1 \
  -DWITH_READLINE=1 \
  -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \
  -DMYSQL_TCP_PORT=3306 \
  -DENABLED_LOCAL_INFILE=1 \
  -DWITH_PARTITION_STORAGE_ENGINE=1 \
  -DEXTRA_CHARSETS=all \
  -DDEFAULT_CHARSET=utf8 \
  -DDEFAULT_COLLATION=utf8_general_ci

  
   There is an error ：
  
   You need to install ncurses：

cd ~/work/src
wget https://invisible-mirror.net/archives/ncurses/ncurses-6.1.tar.gz
tar -xvf ncurses-6.1.tar.gz
cd ncurses-6.1/
./configure
make -j4
sudo make install

  
   then , Continue configuration ：

cmake ./ -DCMAKE_INSTALL_PREFIX=/home/pi/mysql \
  -DMYSQL_DATADIR=/home/pi/mysql/data \
  -DSYSCONFDIR=/home/pi/mysql/ \
  -DWITH_MYISAM_STORAGE_ENGINE=1 \
  -DWITH_INNOBASE_STORAGE_ENGINE=1 \
  -DWITH_MEMORY_STORAGE_ENGINE=1 \
  -DWITH_READLINE=1 \
  -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \
  -DMYSQL_TCP_PORT=3306 \
  -DENABLED_LOCAL_INFILE=1 \
  -DWITH_PARTITION_STORAGE_ENGINE=1 \
  -DEXTRA_CHARSETS=all \
  -DDEFAULT_CHARSET=utf8 \
  -DDEFAULT_COLLATION=utf8_general_ci

   Configuration is successful ：
  

Step six ： compile make

make -j4

  
   There is an error ：

error: ISO C++ forbids comparison between pointer and integer [-fpermissive]

  
   Modify the source code directly ：

vi sql/sql_acl.cc

   Input k, Input again 3037 You can navigate to ：
  
   Continue compiling ：

make -j4

   error ： There is no connection when querying nurces, It is also true that , But this error is not connected to ncurses library , You need to add ( All kinds of methods have been tried , Finally, you can directly force )：
  
   Establish a soft connection ：

sudo ln -s libncurses.so.6 libncurses.so

   then libncur* Copy it all to /lib Next

sudo cp -arf libncurses* ../

   then cmake Configure the mandatory path ：

cmake ./ -DCMAKE_INSTALL_PREFIX=/home/pi/mysql \
  -DMYSQL_DATADIR=/home/pi/mysql/data \
  -DSYSCONFDIR=/home/pi/mysql/ \
  -DWITH_MYISAM_STORAGE_ENGINE=1 \
  -DWITH_INNOBASE_STORAGE_ENGINE=1 \
  -DWITH_MEMORY_STORAGE_ENGINE=1 \
  -DWITH_READLINE=1 \
  -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \
  -DMYSQL_TCP_PORT=3306 \
  -DENABLED_LOCAL_INFILE=1 \
  -DWITH_PARTITION_STORAGE_ENGINE=1 \
  -DEXTRA_CHARSETS=all \
  -DDEFAULT_CHARSET=utf8 \
  -DDEFAULT_COLLATION=utf8_general_ci \
  -DCURSES_LIBRARY=/lib/libncurses.so

   Then continue compiling ：

make

  

Step seven ： install make install

sudo make install

  
   installation is complete ：
  

Step eight ： test mysql

   function mysql：
  
   error ：

Can't connect to local MySQL server through socket '/tmp/mysqld.sock' (2)

   lookup ：

find / -name mysql.sock

  
   Can't find , Then look for the configuration file my.cnf

sudo find / -name my.cnf

  
   The service didn't get up , Some services need to be configured , There is no need to add here , Those who are interested can continue .
