Hello,
Thank you for the workaround, it worked.
Here is the start command
/usr/bin/ionice -c2 -n4 /usr/bin/innobackupex-1.5.1 --slave-info --password=xxxxx
Here is our my.cnf
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
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.
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
Here is entries for some specific programs
The following values assume you have at least 32M ram
This was formally known as [safe_mysqld]. Both versions are currently parsed.
[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 = /data/tmp
default-storage-engine = innodb
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 = 0.0.0.0
bind-address = [xxx.xxx.xxx.xxx]
skip-name-resolve
* Fine Tuning
key_buffer = 16M
max_allowed_packet = 64M
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 = BACKUP
max_connections = 2048
table_open_cache = 4000
table_definition_cache = 4000
open-files-limit = 12000
#thread_concurrency = 10
* Query Cache Configuration
query_cache_limit = 1M
query_cache_size = 16M
max_heap_table_size = 100M
tmp_table_size = 100M
* 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 logging goes to syslog due to /etc/mysql/conf.d/mysqld_safe_syslog.cnf.
Here you can see queries with especially long duration
slow_query_log = 1
slow_query_log_file = /var/log/mysql/mysql-slow.log
long_query_time = 2
#log-queries-not-using-indexes
log-error = /var/log/mysql/mysql-error.log
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.
Replications settings
#skip-slave-start
server-id = 60000313
master-host = [xxx.xxx.xxx.xxx]
master-user = username
master-password = password
relay-log = /var/log/mysql/relay/mysqld-relay-bin
log_bin = /var/log/mysql/mysql-bin.log
log-slave-updates
binlog_format = row
expire_logs_days = 3
max_binlog_size = 100M
sync_binlog = 0
Logs are getting deleted before backup can get past initial stages.
Set value to double the size of max_binlog_size.
* 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!
ignore-builtin-innodb
plugin-load=innodb=ha_innodb_plugin.so
innodb_file_per_table = 1
innodb_file_format = barracuda
innodb_buffer_pool_size=32000M
innodb_log_file_size=256M
innodb_log_buffer_size=4M
innodb_flush_method=O_DIRECT
innodb_flush_log_at_trx_commit=2
* 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
[mysqldump]
quick
quote-names
max_allowed_packet = 64M
[mysql]
#no-auto-rehash # faster start of mysql but no tab completition
[isamchk]
key_buffer = 16M
* IMPORTANT: Additional settings that can override those from this file!
The files must end with ‘.cnf’, otherwise they’ll be ignored.
!includedir /etc/mysql/conf.d/
