mysql 多執行個體部署 Centos7.6 部署3個Mariadb 執行個體
[root@localhost ~]# yum install mariadb-server -y
建立對應的目錄檔案
[root@localhost ~]# mkdir /mysql/{3306,3307,3308}/{data,etc,socket,log,bin,pid} -p
chown -R mysql.mysql /mysql
初始化資料庫檔案
[root@localhost ~]# mysql_install_db --datadir=/mysql/3306/data/ --user=mysql
[root@localhost ~]# mysql_install_db --datadir=/mysql/3307/data/ --user=mysql
[root@localhost ~]# mysql_install_db --datadir=/mysql/3308/data/ --user=mysql
建立對應配置檔案
[root@localhost ~]# cp /etc/my.cnf /mysql/3306/etc
修改對應的配置檔案
[mysqld]
port=3306
datadir=/mysql/3306/data
socket=/mysql/3306/socket/mysql.sock
symbolic-links=0
[mysqld_safe]
log-error=/mysql/3306/log/mariadb.log
pid-file=/mysql/3306/pid/mariadb.pid
另外的2個執行個體調整對應的端口即可
準備啟動腳本 另外的執行個體修改對應的端口即可
[root@localhost ~]# vim /mysql/3306/bin/mysqld
!/bin/bash
chkconfig: 345 80 2
mysql_user="root"
mysql_pwd=""
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
啟動服務
[root@localhost ~]# /mysql/3306/bin/mysqld start
Starting MySQL...
[root@localhost ~]# /mysql/3307/bin/mysqld start
[root@localhost ~]# /mysql/3308/bin/mysqld start
連接配接測試
mysql -S /mysql/3308/socket/mysql.sock -e 'select version()' |
---|
version() |
5.5.60-MariaDB |
關閉資料庫
[root@localhost ~]# /mysql/3306/bin/mysqld stop
