背景
主网节点由于更换机型，部分seed节点和哨兵节点公网ip发生了变更。
问题
之前配置的p2p.seeds和p2p.persistent_peers参数中，部分节点ip无法连通，会出现p2p报错。
解决方案
重新配置新的p2p.seeds和p2p.persistent_peers参数，新的参数如下：
--p2p.seeds="e926c8154a2af4390de02303f0977802f15eafe2@3.16.103.80:26656,7fa5b1d1f1e48659fa750b6aec702418a0e75f13@175.41.191.69:26656,c8f32b793871b56a11d94336d9ce6472f893524b@35.74.8.189:26656"
--p2p.persistent_peers="bbd4aa19249ad42de4fe2ca99209894412fd4707@3.135.138.205:26656,add30aff52c2e43f071c7c2a8be797bef0ed8261@13.214.12.163:26656,e5c4c525df58bb072f2aacebea1cd92d36e83fd3@52.197.157.76:26656,7ce43d169e955309e1cca22468ee3ed9e6fd6f45@54.180.61.142:26656,f7c67632e51fde3c30bc8e41852c1e81aa1d9c2a@3.37.251.158:26656,833777703584393d763b60169e5ca204da91dd83@3.37.121.32:26656,54c195e08ff53e9fd31973dd73d530dcd1506807@52.78.236.126:26656,0eb87d4eb92f8f04d9c2d444dd403671a634af56@13.125.38.24:26656,01b21d39f250a3a5411113aae4a7032eaf9b344e@3.64.37.17:26656,69ea6fb105a3f85d3dd44267d28fae4f0dedf5ab@18.192.220.49:26656,b2a2f799a726b74f83f73b62e1bfef017575b21a@54.151.166.67:26656,3449bb4d2180dfaa9ddb13776177b0e67f95ebb4@54.255.93.228:26656,da32322e27dc9ef5002fed0416f05326fd27723f@54.151.129.9:26656,c88044fb164896bd9ed29bbee7c290c6ac362133@3.112.119.135:26656,39700092b3c7893fdd8ab3af9d66f18113ca47cd@54.150.183.225:26656,9e2aa6bd61c40f08782f7c2ff47d9ea197994b74@54.249.109.150:26656,44cd4db42723a65d61e8803498703b9e4b353036@44.233.186.156:26656,8c7affcb25e8e059f992d4c6494586587782d809@52.40.214.137:26656"
备注：部分节点ip变更，理论上不影响现有节点运行。修改配置不是必须马上重启节点，可以先修改配置，以后重启节点再生效也可以。
