• 1 安裝

  yum install mariadb

• 2 創建多實例對應的目錄結構

  mkdir /mysql/{3306,3307,3308}/{data,etc,socket,log,bin,pid} -pv
  chown -R mysql.mysql /mysql 

• 3 創建多實例的數據庫文件

  mysql_install_db --datadir=/mysql/3306/data/ --user=mysql
  mysql_install_db --datadir=/mysql/3307/data/ --user=mysql
  mysql_install_db --datadir=/mysql/3308/data/ --user=mysql
   
  

• 4 創建對應配置文件

  cp /etc/my.cnf /mysql/3306/etc 
  vim /mysql/3306/etc/my.cnf
  [mysqld]
  port=3306 加一行                                                                                        
  datadir=/mysql/3306/data
  socket=/mysql/3306/socket/mysql.sock
  [mysqld_safe]
  log-error=/mysql/3306/log/mariadb.log
  pid-file=/mysql/3306/pid/mariadb.pid
   
  

  cp /mysql/3306/etc/my.cnf  /mysql/3307/etc/my.cnf   
  /mysql/3307/etc/my.cnf 修改
  cp /mysql/3306/etc/my.cnf  /mysql/3308/etc/my.cnf   
  /mysql/3308/etc/my.cnf 修改

• 5 準備各實例的啟動腳本

vi /mysql/{3306,3307,3308}/bin/mysqld 
cat /mysq/3306/bin/mysqld 
#!/bin/bash
port=3306
mysql_user="root"
mysql_pwd="centos"
cmd_path="/usr/bin"
mysql_basedir="/mysql"
mysql_sock="${mysql_basedir}/${port}/socket/mysql.sock"

function_start_mysql()
{
    if [ ! -e "$mysql_sock" ];then
      printf "Starting MySQL...\n"
      ${cmd_path}/mysqld_safe --defaults-file=${mysql_basedir}/${port}/etc/my.cnf  &> /dev/null  &
    else
      printf "MySQL is running...\n"
      exit
    fi
}

function_stop_mysql()
{
    if [ ! -e "$mysql_sock" ];then
       printf "MySQL is stopped...\n"
       exit
    else
       printf "Stoping MySQL...\n"
       ${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S ${mysql_sock} shutdown
   fi
}

function_restart_mysql()
{
    printf "Restarting MySQL...\n"
    function_stop_mysql
    sleep 2
    function_start_mysql
}

case $1 in
start)
    function_start_mysql
;;
stop)
    function_stop_mysql
;;
restart)
    function_restart_mysql
;;
*)
    printf "Usage: ${mysql_basedir}/${port}/bin/mysqld {start|stop|restart}\n"
esac
 

• 改權限

  chmod +x /mysql/{3306,3307,3308}/bin/mysqld 

• 6 啟動和關閉實例

  /mysql/{3306,3307,3308}/bin/mysqld start 
  /mysql/{3306,3307,3308}/bin/mysqld stop  

• 7 測試連接

  mysql -S /mysql/{3306,3307,3308}/socket/mysql.sock

• 8 安全加固

  mysqladmin  -S /mysql/{3306,3307,3308}/socket/mysql.sock   password ‘centos‘
  vi /mysql/{3306,3307,3308}/bin/mysqld  加上對應centos口令

二進制的安裝

• 1 準備用戶和組

groupadd -r -g 336 mysql
useradd -r -g mysql -u 336 -s /sbin/nologin -d /data/mysql mysql

• 2 準備二進制程序文件和相關文件屬性

  tar xvf mariadb-10.2.23-linux-x86_64.tar.gz -C /usr/local/
  cd  /usr/local/
  ln -s mariadb-10.2.23-linux-x86_64/ mysql
  chown -R root.root /usr/local/mysql/

• 3 PATH變量

cat /etc/profile.d/mysql.sh 
PATH=/usr/local/mysql/bin:$PATH

• 4 準備數據庫數據目錄和數據--改成邏輯卷

mkdir /data/mysql -pv
chown mysql.mysql /data/mysql/
cd /usr/local/mysql
./scripts/mysql_install_db --datadir=/data/mysql --user=mysql

• 5 準備Mysql的服務器端的配置文件

mkdir /etc/mysql
cp /usr/local/mysql/support-files/my-huge.cnf /etc/mysql/my.cnf

vim /etc/mysql/my.cnf
[mysqld]
datadir=/data/mysql 加一行

• 6 準備服務啟動腳本
