今天使用nodejs開發mysql程序時，發現了如下bug提示：{?Error:?write?EPIPE

at?WriteWrap.afterWrite?[as?oncomplete]?(net.js:782:14)

--------------------

at?Protocol._enqueue?(/root/doctracing/node_modules/mysql/lib/protocol/Protocol.js:144:48)

at?PoolConnection.query?(/root/doctracing/node_modules/mysql/lib/Connection.js:200:25)

at?/root/doctracing/mysql.js:22:22

at?Ping.onOperationComplete?(/root/doctracing/node_modules/mysql/lib/Pool.js:110:5)

at?Ping.?(/root/doctracing/node_modules/mysql/lib/Connection.js:502:10)

at?Ping._callback?(/root/doctracing/node_modules/mysql/lib/Connection.js:468:16)

at?Ping.Sequence.end?(/root/doctracing/node_modules/mysql/lib/protocol/sequences/Sequence.js:83:24)

at?Ping.Sequence.OkPacket?(/root/doctracing/node_modules/mysql/lib/protocol/sequences/Sequence.js:92:8)

at?Protocol._parsePacket?(/root/doctracing/node_modules/mysql/lib/protocol/Protocol.js:278:23)

at?Parser.write?(/root/doctracing/node_modules/mysql/lib/protocol/Parser.js:76:12)?errno:?'EPIPE',?code:?'EPIPE',?syscall:?'write',?fatal:?true?}

簡單的來說就是訪問數據庫出問題了，遇到這個問題，解決方式如下：

再my.ini中添加

max_allowed_packet = 1024M

然后重啟mysql即可。
