突发奇想
OBClient 是连贯数据库的客户端工具。可同时兼容拜访 OceanBase 数据库的 MySQL 以及 Oracle 租户。
在常常应用的过程中，突发奇想给本人的 OBClient 定制给非凡的标签显示。

以下是自己调整办法，仅供参考(●'◡'●)
1、装置依赖并拉取 OceanBase 源码
[root@10-186-61-36 ~]# yum install -y git cmake gcc make openssl-devel ncurses-devel rpm-build gcc-c++ bison bison-devel zlib-devel gnutls-devel libxml2-devel openssl-devel libevent-devel libaio-devel[root@10-186-61-36 ~]# git clone https://github.com/oceanbase/obclient.gitCloning into 'obclient'...remote: Enumerating objects: 9229, done.remote: Counting objects: 100% (299/299), done.remote: Compressing objects: 100% (243/243), done.remote: Total 9229 (delta 85), reused 121 (delta 44), pack-reused 8930Receiving objects: 100% (9229/9229), 112.91 MiB | 4.14 MiB/s, done.Resolving deltas: 100% (2960/2960), done.Checking out files: 100% (8729/8729), done.2、批改源代码文件
第一个文件：obclient/client/mysql.cc
if (!status.batch) { ///定位到 1478 行，将 Oceanbase 批改为本人想要的名称，如：zhoujige put_info("Welcome to the OceanBase. Commands end with ; or \\g.", INFO_INFO); my_snprintf((char*) glob_buffer.ptr(), glob_buffer.alloced_length(), ///定位到 1481 行，将 Oceanbase 批改为本人想要的名称，如：zhoujige "Your OceanBase connection id is %lu\nServer version: %s\n", mysql_thread_id(&mysql), is_proxymode ? "":server_version_string(&mysql)); put_info((char*) glob_buffer.ptr(),INFO_INFO); put_info(OB_WELCOME_COPYRIGHT_NOTICE("2000"), INFO_INFO); } ...... ......default_prompt = my_strdup(getenv("MYSQL_PS1") ? getenv("MYSQL_PS1") : ///定位到 1366 行，将 obclient 批改为本人想要的名称，如：zhoujige "obclient [\\d]> ",MYF(MY_WME)); current_prompt = my_strdup(default_prompt,MYF(MY_WME));第二个文件：obclient/include/welcome_copyright_notice.h
#define ORACLE_WELCOME_COPYRIGHT_NOTICE(first_year) \ "Copyright (c) " first_year ", " COPYRIGHT_NOTICE_CURRENT_YEAR \ ", Oracle, MariaDB Corporation Ab and others.\n" #define OB_WELCOME_COPYRIGHT_NOTICE(first_year) \ "Copyright (c) " first_year ", " COPYRIGHT_NOTICE_CURRENT_YEAR \ ///定位到 32 行，将 Oceanbase 批改为本人想要的名称，如：zhoujige ", OceanBase and/or its affiliates. All rights reserved.\n" 3、编译源码生成 OBClient 客户端包
[root@10-186-61-36 ~]# cd obclient/rpm/[root@10-186-61-36 rpm]# sh obclient-build.sh[BUILD] args: TOP_DIR=/root/obclient/rpm/../ PACKAGE=obclient VERSION=2.2.2 RELEASE=1check dependencies profile for el7.x86_64...

用新生成的 OBClient 登录数据库，查看到客户端输入内容已更改为料想的样子。
