我不能代替标准 /etc/my.cnf
标准MySQL5.7容器中的文件。
我正在运行一个mysql 5.7容器(标准docker hub映像)。我想换新的 etc/my.cnf
文件以启用主从操作。我想通过从 docker-compose.yml
文件。
新的 my.cnf
应该是:
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
skip-host-cache

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
secure-file-priv=/var/lib/mysql-files
user=mysql
# Replication and mirroring settings
server-id = 1
auto_increment_increment = 3
auto_increment_offset = 0
log_bin = /var/log/mysql/log-bin
log_bin_index = /var/log/mysql/log-bin.index
binlog_format = row
expire_logs_days = 10
log_slave_updates
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
在 docker-compose.yml
我有以下几行:
mysql:
image: mysql/mysql-server:5.7
container_name: rucio-mysql
volumes:
- ./mysql-config/my-master.cnf:/etc/my.cnf
environment:
- MYSQL_ROOT_PASSWORD=pass
- MYSQL_ROOT_HOST=%
路径是正确的,但是容器立即启动并退出。
提前谢谢,

参考官方mysql docker repo on dockerhub部分“没有cnf文件的配置”,它清楚地提到,可以在基本映像名称之后提供配置标志,我发现运行起来比构建docker映像更容易。我的示例docker运行命令将内存使用率从默认的480MB优化到仅100MB
docker run-d-p 3306:3306-e mysql\u database=test-e mysql\u root\u password=tooor-e mysql\u user=test-e mysql\u password=test-v/mysql:/var/lib/mysql--name mysqldb mysql--table\u definition\u cache=100--performance\u schema=0--default authentication plugin mysql\u native\u password

不能将文件指定为卷,这样做行不通。卷是目录。
如果您的配置是常量,并且不希望在容器执行之间发生更改,只需从中继承您自己的容器即可
mysql/mysql-server:5.7
以及COPY
在其中添加新配置:dockerfile文件
用你的新形象
docker-compose
.如果配置有问题,最好使用卷,但在容器启动时必须手动覆盖它。像这样:
docker-compose.yml公司
