1、工具介紹

  • 前幾日用mysql-sandbox來搭建MySQL8.0新版本時發現用不了，提示須要使用dbdeployer才行，瞬間以爲mysql-sandbox不香了，只好咬咬牙來熟悉dbdeployer了。
  • dbdeployer是使用go語言重構的sandbox，和sandbox同一個做者。
  • 固然，dbdeployer延續了sandbox全部功能。可實現一鍵部署不一樣架構、不一樣版本的數據庫環境。如，MySQL 主從複製、GTID 模式複製、MySQL 組複製(單主模式、多主模式等)
  • 完整的數據庫類型支持及版本，可在安裝完 dbdeployer 後使用dbdeployer admin capabilities命令進行查看，如下是當前已支持數據庫及組件類型
  1. -- pxc (Percona XtraDB Cluster)
  2. -- mysql-shell
  3. -- mysql (MySQL server)
  4. -- percona (Percona Server)
  5. -- mariadb
  6. -- tidb (TiDB isolated server)
  7. -- ndb (MySQL NDB Cluster)

2、工具安裝

  • OS：centos8
  • dbdeployer：1.54.0
  • mysql：8.0.20

2.1 dbdeployer工具下載

直接到github下載release包便可：node

https://github.com/datacharmer/dbdeployer/releasesmysql

2.2 解壓

軟件解壓後實際只有一個單獨的編譯好的可執行文件linux

tar -zxvf dbdeployer-1.54.0.linux.tar.gz

2.3 賦予可執行權限

chmod +x dbdeployer-1.54.0.linux

2.4 移動到系統可執行目錄下方便使用

mv dbdeployer-1.54.0.linux /usr/local/bin/dbdeployer

2.5 驗證是否可使用

[root@db01 tmp]# dbdeployer --version
dbdeployer version 1.54.0
[root@db01 tmp]# dbdeployer --help
dbdeployer makes MySQL server installation an easy task.
Runs single, multiple, and replicated sandboxes.

Usage:
  dbdeployer [command]

Available Commands:
  admin           sandbox management tasks
  cookbook        Shows dbdeployer samples
  defaults        tasks related to dbdeployer defaults
  delete          delete an installed sandbox
  delete-binaries delete an expanded tarball
  deploy          deploy sandboxes
  downloads       Manages remote tarballs
  export          Exports the command structure in JSON format
  global          Runs a given command in every sandbox
  help            Help about any command
  import          imports one or more MySQL servers into a sandbox
  info            Shows information about dbdeployer environment samples
  init            initializes dbdeployer environment
  sandboxes       List installed sandboxes
  unpack          unpack a tarball into the binary directory
  update          Gets dbdeployer newest version
  usage           Shows usage of installed sandboxes
  use             uses a sandbox
  versions        List available versions

Flags:
      --config string           configuration file (default "/root/.dbdeployer/config.json")
  -h, --help                    help for dbdeployer
      --sandbox-binary string   Binary repository (default "/root/opt/mysql")
      --sandbox-home string     Sandbox deployment directory (default "/root/sandboxes")
      --shell-path string       Which shell to use for generated scripts (default "/usr/bin/bash")
      --skip-library-check      Skip check for needed libraries (may cause nasty errors)
  -v, --version                 version for dbdeployer

Use "dbdeployer [command] --help" for more information about a command.

2.6 初始化環境

安裝dbdeployer以後，能夠當即使用如下命令爲操做作好準備的環境，此命令會建立必要的目錄，而後下載最新的MySQL二進制文件，在默認的位置解壓它們。git

dbdeployer init

3、基本使用

3.1 自行下載MySQL並解壓

訪問 https://downloads.mysql.com/archives/community/ 可下載各不一樣的MySQLgithub

dbdeployer unpack /tmp/mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz

3.2 使用dbdeployer工具下載MySQL並解壓

3.2.2 下載並解壓指定軟件包

使用dbdeployer downloads get file_name，從上面的列表中複製須要下載的版本並粘貼文件名。例如：sql

[root@mysql8 ~]# dbdeployer downloads get-unpack  mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz
Downloading mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz
.........105 MB.........210 MB.........315 MB.....  376 MB
File /root/mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz downloaded
Checksum matches
Unpacking tarball mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz to $HOME/opt/mysql/5.7.31
.........100.........200.........300302
Renaming directory /root/opt/mysql/mysql-5.7.31-linux-glibc2.12-x86_64 to /root/opt/mysql/5.7.31

3.3 檢查DBdeployer的已安裝/可用的tarball二進制軟件包列表

[root@mysql8 ~]# dbdeployer versions
Basedir: /root/opt/mysql
5.7.31  8.0.20  8.0.21
[root@mysql8 ~]# tree $HOME/opt -L 2
/root/opt
└── mysql
    ├── 5.7.31
    ├── 8.0.20
    └── 8.0.21

3.4 快速部署實例dbdeployer deploy -h

3.4.1 該命令能夠部署單個，多個或複製的MySQL沙箱實例
multiple    建立多個獨立的mysql
replication 建立複製環境的mysql
single      建立單節點的mysql
3.4.2 若是要使用多個相同版本的沙箱，且沒有任何複製關係，請使用dbdeployer deploy multiple -h,例如：
dbdeployer deploy multiple 8.0.21
ps -ef | grep mysqld

默認建立三個節點，咱們能夠用-n選項來指定須要建立的節點數，--force強制覆蓋以前的安裝shell

dbdeployer deploy multiple -n 2 --force 8.0.21
3.4.3 若是須要安裝一主多從的複製環境，請使用dbdeployer deploy replication -h，例如：
dbdeployer deploy replication 5.7.31
[root@mysql8 rsandbox_5_7_31]# ./status_all 
REPLICATION  /root/sandboxes/rsandbox_5_7_31
master : master on  -  port	19832 (19832)
node1 : node1 on  -  port	19833 (19833)
node2 : node2 on  -  port	19834 (19834)

默認爲一主兩從三節點版，一樣可使用-n選項來指定節點數，--gtid指定爲gtid複製模式數據庫

dbdeployer deploy replication 5.7.31 -n 2 --gtid --force
[root@mysql8 rsandbox_5_7_31]# ./status_all 
REPLICATION  /root/sandboxes/rsandbox_5_7_31
master : master on  -  port	19832 (19832)
node1 : node1 on  -  port	19833 (19833)
3.4.4 若是隻想測試單個實例MySQL，請使用dbdeployer deploy single -h，例如：
dbdeployer deploy single 8.0.20
3.4.5 部署一套多主MGR集羣
dbdeployer deploy --topology=group replication 8.0.20

4、實例組操做

一鍵部署完成後會在 $HOME/sandboxes 目錄下生成各實例組對應的數據目錄，該目錄包含如下信息(部分信息)json

  • 一鍵啓停該組全部實例的腳本
  • 一鍵登陸數據庫腳本
  • 一鍵重置該組全部實例的腳本（清除全部測試數據並從新初始化成全新的主從）
  • 主從實例的數據目錄（主庫爲 master，從庫分別爲 node一、node2 依次遞增）
  • 各實例的配置文件
  • 默認用戶受權命令
  • 單獨啓停實例命令
  • binlog、relaylog 解析命令
4.1 使用示例
[root@mysql8 ~]# cd $HOME/sandboxes/group_msb_8_0_20
[root@mysql8 group_msb_8_0_20]# ls
check_nodes       metadata_all  n3     node3           sbdescription.json  status_all        test_sb_all      use_all_slaves
clear_all         n1            node1  replicate_from  send_kill_all       stop_all          use_all
initialize_nodes  n2            node2  restart_all     start_all           test_replication  use_all_masters
4.2 查看該組全部實例狀態
[root@mysql8 group_msb_8_0_20]# ./status_all 
MULTIPLE  /root/sandboxes/group_msb_8_0_20
node1 : node1 on  -  port	22021 (22021)
node2 : node2 on  -  port	22022 (22022)
node3 : node3 on  -  port	22023 (22023)
4.3 一鍵重啓該組全部實例
[root@mysql8 group_msb_8_0_20]# ./restart_all 
# executing 'stop' on /root/sandboxes/group_msb_8_0_20
executing 'stop' on node3
stop /root/sandboxes/group_msb_8_0_20/node3
executing 'stop' on node2
stop /root/sandboxes/group_msb_8_0_20/node2
executing 'stop' on node1
stop /root/sandboxes/group_msb_8_0_20/node1
# executing 'start' on /root/sandboxes/group_msb_8_0_20
executing "start" on node 1
. sandbox server started
executing "start" on node 2
. sandbox server started
executing "start" on node 3
. sandbox server started
4.4 單獨操做某一節點，需進入對應節點數據目錄
[root@mysql8 group_msb_8_0_20]# cd ~/sandboxes/group_msb_8_0_20/node1
[root@mysql8 node1]# ls
add_option            clone_from       data          metadata        replicate_from      send_kill      start      test_sb
after_start           connection.conf  grants.mysql  my              restart             show_binlog    start.log  tmp
clear                 connection.json  init_db       my.sandbox.cnf  sbdescription.json  show_log       status     use
clone_connection.sql  connection.sql   load_grants   mysqlsh         sb_include          show_relaylog  stop
4.5 登錄指定實例
[root@mysql8 node1]# ./use
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8

node1 [localhost:22021] {msandbox} ((none)) >
4.6 msyql日誌管理

每一個實例下有便捷日誌腳本centos

show_log    #顯示錯誤日誌或常規日誌
show_binlog
show_relaylog
4.7 相關mysql用戶密碼
user name password privileges
root@localhost msandbox all on *.* with grant option
msandbox@localhost msandbox all on *.*
rsandbox@127.% rsandbox REPLICATION SLAVE
4.8 本地root用戶登錄
mysql -uroot -pmsandbox -S /tmp/mysql_sandbox8020.sock

5、dbdeployer 經常使用管理命令

如下是使用 dbdeployer 過程當中總結的經常使用命令，詳細使用方式可查看文末 dbdeployer 文檔連接。

5.1 更新dbdeployer
dbdeployer update
5.2 列出以解壓的MySQL版本
dbdeployer versions
5.3 列出已安裝的沙箱實例
dbdeployer sandboxes
5.4 刪除已安裝沙箱實例
dbdeployer delete multi_msb_8_0_21
5.5 鎖定及解鎖一個或多個沙箱實例，以防止刪除
[root@mysql8 ~]# dbdeployer admin lock group_msb_8_0_20
Sandbox group_msb_8_0_20 locked
[root@mysql8 ~]# dbdeployer admin unlock group_msb_8_0_20
Sandbox group_msb_8_0_20 unlocked
