问题描述
我遇到了服务器始终会出现此2006错误的问题。我更改了首选项以及cnf文件(max_packet大小)中的设置。每天早上,当我检查服务器时,它将显示2006错误。我将不得不转到工作台的主页并手动双击本地主机,然后连接就可以了(已连接)。我已经附加了cnf行和MysqL工作台映像。请帮忙。谢谢。
The MysqL database server configuration file.
You can copy this to one of:
- "/etc/MysqL/my.cnf" to set global options,- "~/.my.cnf" to set user-specific options.
One can use all long options that the program supports.
Run program with --help to get a list of available options and with
--print-defaults to see which it would actually understand and use.
For explanations see
http://dev.MysqL.com/doc/MysqL/en/server-system-variables.html
This will be passed to all MysqL clients
It has been reported that passwords should be enclosed with ticks/quotes
escpecially if they contain "#" chars...
Remember to edit /etc/MysqL/debian.cnf when changing the socket location.
Here is entries for some specific programs
The following values assume you have at least 32M ram
[MysqLd_safe]
socket = /var/run/MysqLd/MysqLd.sock
nice = 0
[MysqLd]
Basic Settings
user = MysqL
pid-file = /var/run/MysqLd/MysqLd.pid
socket = /var/run/MysqLd/MysqLd.sock
port = 3306
basedir = /usr
datadir = /var/lib/MysqL
tmpdir = /tmp
lc-messages-dir = /usr/share/MysqL
skip-external-locking
Instead of skip-networking the default is Now to listen only on
localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
* Fine Tuning
key_buffer_size = 16M
max_allowed_packet = 256M
thread_stack = 192K
thread_cache_size = 8
This replaces the startup script and checks MyISAM tables if needed
the first time they are touched
myisam-recover-options = BACKUP
max_connections = 200
table_cache = 64
thread_concurrency = 10
* Query Cache Configuration
query_cache_limit = 5M
query_cache_size = 16M
* Logging and Replication
Both location gets rotated by the cronjob.
Be aware that this log type is a performance killer.
As of 5.1 you can enable the log at runtime!
general_log_file = /var/log/MysqL/MysqL.log
general_log = 1
Error log - should be very few entries.
log_error = /var/log/MysqL/error.log
Here you can see queries with especially long duration
log_slow_queries = /var/log/MysqL/MysqL-slow.log
long_query_time = 2
log-queries-not-using-indexes
The following can be used as easy to replay backup logs or for replication.
note: if you are setting up a replication slave,see README.Debian about
other settings you may need to change.
server-id = 1
log_bin = /var/log/MysqL/MysqL-bin.log
expire_logs_days = 10
max_binlog_size = 100M
binlog_do_db = include_database_name
binlog_ignore_db = include_database_name
* InnoDB
InnoDB is enabled by default with a 10MB datafile in /var/lib/MysqL/.
Read the manual for more InnoDB related options. There are many!#
* Security Features
Read the manual,too,if you want chroot!
chroot = /var/lib/MysqL/
For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
ssl-ca=/etc/MysqL/cacert.pem
ssl-cert=/etc/MysqL/server-cert.pem
ssl-key=/etc/MysqL/server-key.pem
