1. 无法启动第一个节点

   2017-11-18T15:53:38.737048Z 0 [Note] /usr/local/MySQL/bin/mysqld: Shutdown complete

   问题主要描述：错误日志提示无法成功加入节点

   原因：第一个节点启动时需要指定自己为作为集群启动

   解决办法:加--wsrep-new-cluster参数启动，官方指定的bootstrap-pxc参数并不生效

2. 第二个节点无法加入

   2017-11-19T15:55:29.227793Z 0 [ERROR] WSREP: Process completed with error: wsrep_sst_xtrabackup-v2 --role 'donor' --address '192.168.1.103:4444/xtrabackup_sst//1' --socket '/data/mysql/3306/tmp/mysql3306.sock' --datadir '/data/mysql/3306/data/' --defaults-file '/data/mysql/3306/my.cnf' --defaults-group-suffix ''  --binlog 'mysql-bin' --gtid 'df47a753-cd3d-11e7-85b5-66f48d655632:0': 32 (Broken pipe)
   2017-11-19T15:55:29.227868Z 0 [ERROR] WSREP: Command did not run: wsrep_sst_xtrabackup-v2 --role 'donor' --address '192.168.1.103:4444/xtrabackup_sst//1' --socket '/data/mysql/3306/tmp/mysql3306.sock' --datadir '/data/mysql/3306/data/' --defaults-file '/data/mysql/3306/my.cnf' --defaults-group-suffix ''  --binlog 'mysql-bin' --gtid 'df47a753-cd3d-11e7-85b5-66f48d655632:0'
   问题描述：无法成功传输SST

    在mysql/bin目录下执行wsrep_sst_xtrabackup-v2 --role 'donor' --address '192.168.1.103:4444/xtrabackup_sst//1' --socket '/data/mysql/3306/tmp/mysql3306.sock' --datadir '/data/mysql/3306/data/' --defaults-file '/data/mysql/3306/my.cnf' --defaults-group-suffix ''  --binlog 'mysql-bin' --gtid 'df47a753-cd3d-11e7-85b5-66f48d655632:0'

   提示：

      which: no socat in (/usr/sbin:/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin:/usr/local/pxc/bin:/root/bin)      

   原因：缺少依赖组件socat

   解决办法：yum -y install socat

3. 第二个几点无法加入

   2017-11-19T15:15:11.735984Z 2 [Note] WSREP: New cluster view: global state: 50970ac2-cc82-11e7-8b90-c716227b4ac7:0, view# 8: Primary, number of nodes: 2, my index: 0, protocol version 3

   问题描述：无法传输SST

   原因：缺少依赖组件lsof

   解决办法：yum -y install lsof

4. 建议：1.先单机启动，更改完root账号，并创建好sst传输账号后，再启动第一个节点

         2.若xtrabackup-v2传输方式总是报错，可以改用rsync，并注释掉auth行

         3.第二第三个节点启动失败，可以暴力一点删掉data目录下面的文件后重新初始化

         4.可以删除data目录下面g开头的两个集群信息文件重新启动进行尝试排错

         5.telnet主节点的4567端口判断网络和主节点的mysqld服务是否正常。

         6.libaio,openssl也可以考虑安装
