复制代码 根据OceanBase官网介绍,当利用MySQL 8.0客户端毗连OceanBase时,必要在毗连命令上加–default_auth=mysql_native_pasowrd,因MySQL 8.0和之前的版本有不同的加密算法,MySQL 8.0之前默认加密算法是 “mysql_native_password”,而 MySQL8.0 的默认加密算法是"caching_sha2_password"。
但通过测试,利用MySQL 8.0客户端毗连OceanBase 4.0 社区版时,可以不加mysql_native_password也能正常毗连。
我也测试了下OceanBase 3企业版,发现利用MySQL 8.0 也可以不用加 --default_auth=mysql_native_pasowrd能正常毗连OceanBase数据库,以下是测试毗连企业版。

复制代码 二、通过 obclient毗连 OceanBase 数据库
2.1、安装obclient
obclient是一个交互式和批处置处罚查询工具,通过 obclient您可以毗连 OceanBase 数据库。利用obclient必要先提前安装OBClient工具。
可以通过如下两种方式来安装obclient工具:
♦ 通过yum 安装 OBClient客户端
♦ 通过OceanBase官网下载rpm包安装obclient
2.2、检察obclient版本信息
- [admin@obproxy-node ~]$ obclient --version
- obclient Ver Distrib 10.4.18-MariaDB, for Linux (x86_64) using readline 5.1
- [admin@obproxy-node ~]$ obclient --help
- obclient Ver Distrib 10.4.18-MariaDB, for Linux (x86_64) using readline 5.1
- Copyright (c) 2000, 2018, OceanBase and/or its affiliates. All rights reserved.
-
- Usage: obclient [OPTIONS] [database]
-
- Default options are read from the following files in the given order:
- /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
- The following groups are read: mysql mariadb-client client client-server client-mariadb
- The following options may be given as the first argument:
- --print-defaults Print the program argument list and exit.
- --no-defaults Don't read default options from any option file.
- The following specify which files/extra groups are read (specified before remaining options):
- --defaults-file=# Only read default options from the given file #.
- --defaults-extra-file=# Read this file after the global files are read.
- --defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
-
- -?, --help Display this help and exit.
- -I, --help Synonym for -?
- --abort-source-on-error
- Abort 'source filename' operations in case of errors
- --auto-rehash Enable automatic rehashing. One doesn't need to use
- 'rehash' to get table and field completion, but startup
- and reconnecting may take a longer time. Disable with
- --disable-auto-rehash.
- (Defaults to on; use --skip-auto-rehash to disable.)
