dbdeployer 快速安装MySQL8.0各测试环境

  Linux系统必须安装有Go语言：
    下载最新的包：https://github.com/datacharmer/dbdeployer/releases  
    解压：  tar -xzf dbdeployer-1.5.0.linux.tar.gz
    赋予执行权限： chmod +x dbdeployer-1.5.0.linux
    拷贝到bin目录： sudo mv dbdeployer-1.5.0.linux /usr/local/bin/dbdeployer

 dbdeployer可以快速搭建多个MySQL测试环境（主从复制,主主复制，GTID复制，组复制（单主或多主），多源复制等） 

  部署MySQL环境都是秒级别（10-30秒，根据实例多少有关），使用起来很方便，还有各种管理命令。

 dbdeployer unpack mysql-8.0.-linux-glibc2.-x86_64.tar.gz --sandbox-binary=/usr/local

 dbdeployer deploy single 8.0. --bind-address=0.0.0.0  --port= --sandbox-home=/home/data  --sandbox-binary=/usr/local
 --sandbox-home 数据文件的安装目录
 --sandbox-binary 是安装MySQL的二进制文件程序目录
 --bind-address 4个0代表全部
 --port 代表MySQL的端口

   -- cd 到/home/data下

  --mysql 8.0.11 创建用户  ./use 进去 修改密码和权限，否则不能修改Authentication plugin 'caching_sha2_password' cannot be loaded:
  ALTER user'root'@'localhost' IDENTIFIED  WITH mysql_native_password BY 'cc.123';
  create USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'cc.123';

  FLUSH PRIVILEGES; 

  --再授权
  mysql -u root -p -S /tmp/mysql_sandbox3308.sock -- 进入
  grant all on *.* to 'root'@'%' WITH GRANT OPTION; 

  FLUSH PRIVILEGES; 
  如果想在安装的时候就赋予权限，直接使用参数：
    --post-grants-sql="grant all on *.* to 'root'@'%' WITH GRANT OPTION "   

 --删除已经部署的mysql

dbdeployer delete rsandbox_8_0_11 --sandbox-home=/home/data -- sandbox-binary=/usr/local;

   --这里的：rsandbox_8_0_11  是文件夹名称

--部署1主多从（1拖4) (using ports 18601, 18602, 18603,18604)
   dbdeployer deploy replication 8.0.11 --bind-address=0.0.0.0 --base-port=18600 --sandbox-home=/home/data --sandbox-binary=/usr/local --nodes=4;

--部署4个mysql,(using ports 18601, 18602, 18603,18604)
   dbdeployer deploy multiple 8.0.11 --bind-address=0.0.0.0 --base-port=18600 --sandbox-home=/home/data --sandbox-binary=/usr/local --nodes=4;

   安装3主2从（多主多从）：

dbdeployer deploy replication --topology=fan-in   --nodes=5 --master-list="1,2,3"  --bind-address=0.0.0.0  --native-auth-plugin  --slave-list="4,5"  8.0.11 --sandbox-home=/home/data  --remote-access="%" --sandbox-binary=/usr/local  --db-password="cc.123" --db-user="sa"  --post-grants-sql="grant all on *.* to 'sa'@'%' WITH GRANT OPTION "

--remote-access="%"  账户远程访问的IP，% 为全部

--db-user 新数据库账户

--db-password 数据库密码

--post-grants-sql  后面执行的数据库授权Sql

--native-auth-plugin  客户端如SQLLog可以访问MySQL，是在MySQL 8.0.4+ 有效

   安装组复制：

dbdeployer deploy replication --topology=group     --bind-address=0.0.0.0      8.0.11 --sandbox-home=/home/data --remote-access="%" --sandbox-binary=/usr/local --native-auth-plugin  --db-password="cc.123" --db-user="sa"  --post-grants-sql="grant all on *.* to 'sa'@'%' WITH GRANT OPTION ";

加上：--single-primary  明确是单主

dbdeployer deploy --topology=all-masters replication  --bind-address=0.0.0.0   8.0.11 --sandbox-home=/home/td  --remote-access="%" --sandbox-binary=/usr/local --native-auth-plugin --db-password="cc.123" --db-user="sa"  --post-grants-sql="grant all on *.* to 'sa'@'%' WITH GRANT OPTION " --concurrent；

说明:

$ dbdeployer deploy replication 5.7.21
        # (implies topology = master-slave) 默认主从

$ dbdeployer deploy --topology=master-slave replication 5.7.21
        # (explicitly setting topology) 明确主从

$ dbdeployer deploy --topology=group replication 5.7.21  组复制多主

   注意： 安装的过程中当前目录一定有，不然报错。比如在删除的rsandbox_8_0_11文件夹下执行dbdeployer命令

   配置后的备份：cd到MySQL的bin下执行   

./mysqldump -h 192.168.60.167  -u sa -p -P8011 --socket=/tmp/mysql_sandbox8011.sock  test > test_db.sql;
