Furthermore, it will execute files with extensions `.sh`, `.sql` and `.sql.gz` that are found in `/docker-entrypoint-initdb.d`. Files will be executed in alphabetical order. You can easily populate your mysql services by mounting a SQL dump into that directory and provide custom images with contributed data. SQL files will be imported by default to the database specified by the `MYSQL_DATABASE` variable. 140 | 141 | *注：`sakila` 是 MySQL 的官方示例数据库 [https://dev.mysql.com/doc/sakila/en/sakila-installation.html](https://dev.mysql.com/doc/sakila/en/sakila-installation.html)* 142 | 143 | #### 配置实例参数 144 | 145 | ```yaml 146 | ... 147 | command: [ 148 | "--log-bin=mysql-bin", 149 | "--server-id=${MASTER_SERVER_ID}", 150 | "--character-set-server=utf8mb4", 151 | "--collation-server=utf8mb4_unicode_ci", 152 | "--innodb_flush_log_at_trx_commit=1", 153 | "--sync_binlog=1" 154 | ] 155 | ... 156 | ``` 157 | 158 | 使用执行参数可以不依靠 `my.cnf` 对实例进行配置，详细资料可以查看镜像说明页面： 159 | 160 | https://hub.docker.com/_/mysql/ 161 | 162 | > Configuration without a cnf file 163 | > Many configuration options can be passed as flags to `mysqld`. This will give you the flexibility to customize the container without needing a `cnf` file. For example, if you want to change the default encoding and collation for all tables to use UTF-8 (utf8mb4) just run the following: 164 | >``` 165 | >$ docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci 166 | >``` 167 | > If you would like to see a complete list of available options, just run: 168 | >``` 169 | >$ docker run -it --rm mysql:tag --verbose --help 170 | >``` 171 | 172 | #### 主从配置 173 | 174 | ##### init-master.sh 175 | 176 | ```shell 177 | #!/bin/bash 178 | 179 | set -e 180 | 181 | # create replication user 182 | 183 | mysql_net=$(ip route | awk '$1=="default" {print $3}' | sed "s/\.[0-9]\+$/.%/g") 184 | 185 | MYSQL_PWD=${MYSQL_ROOT_PASSWORD} mysql -u root \ 186 | -e "CREATE USER '${MYSQL_REPLICATION_USER}'@'${mysql_net}' IDENTIFIED BY '${MYSQL_REPLICATION_PASSWORD}'; \ 187 | GRANT REPLICATION SLAVE ON *.* TO '${MYSQL_REPLICATION_USER}'@'${mysql_net}';" 188 | ``` 189 | 190 | 在主库中添加用于复制的帐号，由于镜像默认开启 `--skip-name-resolve` 参数，因此只能通过 IP 配置权限。 191 | 192 | *注：脚本中是获取容器默认网关网段后添加用户，不适用于生产环境。* 193 | 194 | ##### init-node.sh 195 | 196 | ```shell 197 | #!/bin/bash 198 | 199 | # check mysql master run status 200 | 201 | set -e 202 | 203 | until MYSQL_PWD=${MASTER_MYSQL_ROOT_PASSWORD} mysql -u root -h mysql-master ; do 204 | >&2 echo "MySQL master is unavailable -
