Mysql已經離開媒體寺廟

Question

真的很想得到一些幫助。

我不斷收到錯誤上傳大文件75MB時，Mysql已經消失。 20mb以下的任何內容都可以上傳。

所以我在這裏查看了其他帖子上的這個錯誤。我在媒體上，但不幸的是他們說他們的範圍之外。

我已經編輯在/etc/my.cnf中

[client] 
port   = 3306 
socket   = /var/lib/mysql/mysql.sock 

[mysqld_safe] 
log-error=/var/log/mysqld.log 
pid-file=/var/run/mysqld/mysqld.pid 

innodb_buffer_pool_size=2M 
innodb_additional_mem_pool_size=500K 
innodb_log_buffer_size=500K 
innodb_thread_concurrency=2 

[mysqld] 
local-infile=0 
datadir=/var/lib/mysql 
user=mysql 
symbolic-links=0 

max_connections = 150 
wait_timeout = 600 
query-cache-type = 1 
query-cache-size = 16M 
query_cache_limit = 2M 
thread_cache_size = 16 
tmp_table_size = 32M 
max_heap_table_size = 32M 
join_buffer_size = 2M 
table_open_cache = 128 

port   = 3306 
socket   = /var/lib/mysql/mysql.sock 
skip-external-locking 
key_buffer_size = 16M 
max_allowed_packet = 1M 
sort_buffer_size = 512K 
net_buffer_length = 8K 
read_buffer_size = 256K 
read_rnd_buffer_size = 512K 
myisam_sort_buffer_size = 8M 

innodb_buffer_pool_size = 16M 
innodb_additional_mem_pool_size = 2M 
innodb_log_buffer_size = 8M 

[mysqldump] 
quick 
max_allowed_packet = 16M 

[mysql] 
no-auto-rehash 

[myisamchk] 
key_buffer_size = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

這個文件my.cnf中，所以我有UPED等待超時部分600應該是綽綽有餘？

我有我的php.ini文件設置如下。

，所以我有UPED任何幫助，這是推動我瘋了什麼什麼建議

請增加wait_timeout

兩個可能的原因的時間可能是： -

1. 服務器超時和關閉連接。如何解決：檢查 wait_timeout變量在你的mysqld的my.cnf/my.ini配置中 文件足夠大。
2. 服務器丟失了一個不正確或太大的數據包。如果mysqld得到一個太大或不正確的 數據包，它會認爲某些東西的 出現了錯誤的客戶端並關閉了連接。您可以通過在my.cnf/my.ini文件中增加 max_allowed_pa​​cket的值來增加最大數據包大小限制。
