如何将MySQL PXC集群配置为使用IPv6地址？

前阵子为PXC集群配置IPv6支持，遇见奇怪的问题，就是SST同步时总是报错，为此在官网论坛提交了问题，未得到答案，最后偶然得到了答案，详见官方论坛： https://forums.percona.com/t/sst-cant-support-ipv6/26140 结论如下。 Finally, I found the solution is turn off pxc_encrypt_cluster_traffic, then it works well. And this is my major part of conf file: [mysqld] wsrep_cluster_address=gcomm://[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:4567,[fd15:4ba5:5a2b:1008:f814:e50e:acbd:12]:4567 wsrep_node_address=[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:4567 wsrep_node_incoming_address=[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:3306 wsrep_sst_receive_address=[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:4444 wsrep_cluster_name=pxc-cluster pxc_strict_mode=ENFORCING wsrep_sst_method=xtrabackup-v2 pxc_encrypt_cluster_traffic=OFF wsrep_provider_options="gmcast.listen_addr=tcp://[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:4567;ist.recv_addr=tcp://[fd15:4ba5:5a2b:1008:f814:e50e:acbd:11]:4568" So the most important things are these two: 1. Set every port of IPv6 like above 2. Set pxc_encrypt_cluster_traffic=OFF
