手动部署configserver后，启动obproxy无法正确连接

AntTech_L7W5U5 · 2022 年12 月 5 日 16:42

【使用环境】
测试环境

【组件】
config server tool
obproxy

【使用版本】
config server-master-8585d2d869bf46b504c4f1600c54ab1ebd4d6e9b
obproxy-3.2.3.5

【诉求】

自己编译运行config server并注册启动的方式是否可行？
如果可行的话想请教一下为何proxy无法正常连接observer？

【问题描述】
使用config server的形式启动obproxy后，无法进行连接。报错提示找不到集群。
通过报错看到时curl出错了（直接在这台主机上运行curl命令请求接口是有数据返回的）

启动obproxy

./bin/obproxy -p 2883 -n mycluster -o "prometheus_sync_interval=1s,obproxy_config_server_url='http://192.168.2.42:8088/services?Action=GetObProxyConfig&ObproxyClusterName=mycluster',prometheus_listen_port=2884,enable_metadb_used=false,skip_proxy_sys_private_check=true,log_dir_size_threshold=10G,proxy_mem_limited=2G,enable_proxy_scramble=true,enable_strict_kernel_release=false"

通过proxy连接observer，连接失败

注册ob集群的信息是通过手动调用的POST请求吗，可以在OB集群内设置obconfig_url这个参数，然后rs切主一次，(alter system switch rootservice leader server ‘1.1.1.1:2882’ ), 会触发自动汇报rs信息到configserver

好的我试试，感谢！

OBserver设置config server URL并切换leader

obclient [oceanbase]> alter system set obconfig_url = 'http://192.168.2.42:8088/services?Action=ObRootServiceInfo&ObCluster=obcluster';
Query OK, 0 rows affected (0.078 sec)

obclient [oceanbase]> ALTER SYSTEM SWITCH ROOTSERVICE LEADER server '172.20.134.2:2882';
Query OK, 0 rows affected (0.004 sec)

查看config server的日志，发现一些HTTP 500的错误：

观察发现obproxy启动并尝试连接后configserver并没有打印任何请求信息

和顺 · 2022 年12 月 6 日 14:06

登录obproxy的 root@proxysys 下查看一下：
mysql -h${obproxy_ip} -P${obproxy_port} -uroot@proxysys -pxxx
show proxyconfig like ‘enable_cluster_checkout’;
看看当前该配置项如果是false的话，登录的时候就不能加上“#集群名”了。

AntTech_L7W5U5 · 2022 年12 月 6 日 14:37

确认了下，值为True

curl 一下obconfig_url设置的那个url地址，能正确的返回rs信息了吗

AntTech_L7W5U5 · 2022 年12 月 7 日 17:13

可以正确返回的，这是在部署proxy的机器上执行的CURL

obproxy 中是否一直在刷请求configserver的日志呢，现在configserver的日志中有看到调用
curl “http://192.168.2.42:8088/services?Action=GetObProxyConfig&ObproxyClusterName=myproxy”
这个接口的吗，如果没有访问成功configserver，应该是没办法获取到rs_list

AntTech_L7W5U5 · 2022 年12 月 8 日 10:08

是的没错，一直在刷，但是都没有成功:

而且ob server这边的ob-configserver.log并没有发现有对应时间点的GET请求进来

那应该是一直没有收到请求，ps -ef|grep obproxy看一下这个进程的启动命令
还有看一下obproxy安装目录下etc目录里面的obproxy.config.bin
可以用这个命令查看里面的内容
strings obproxy_config.bin

找到问题了，麻烦老师了，补充一下结论：
第一次启动proxy使用的是RSlist的形式，此时可以连接成功。
第二次启动为configserver URL的形式，通过strings obproxy_config.bin看到RSlist与configserver URL同时存在于配置文件内

解决方法：
删除proxy后重启安装，采用configserver URL的形式启动，连接成功
