首先从镜像仓库拉取mysql5.7到本地
docker pull mysql:5.7.28
后面操作也是和之前做的nginx教程差不多,主要是用来记录
首先查看镜像
docker iamges
可以看到我们刚才拉取的镜像
REPOSITORY TAG IMAGE ID CREATED SIZE mysql 5.7.28 db39680b63ac 18 months ago 437MB
然后创建mysql需要的目录,建议将本地目录映射到docker内的mysql数据存储目录,这样降低数据丢失的风险
sudo mkdir /data/mysql sudo mkdir /data/mysql/{conf,data}
创建mysql配置文件
sudo vim /data/mysql/conf/my.cnf
内容如下
[mysqld] server-id = 1 init-connect = 'SET NAMES utf8mb4' character-set-server = utf8mb4 skip-name-resolve #skip-networking back_log = 300 max_connections = 1000 max_connect_errors = 6000 open_files_limit = 65535 table_open_cache = 128 max_allowed_packet = 500M binlog_cache_size = 1M max_heap_table_size = 8M tmp_table_size = 16M read_buffer_size = 2M read_rnd_buffer_size = 8M sort_buffer_size = 8M join_buffer_size = 8M key_buffer_size = 4M thread_cache_size = 8 query_cache_type = 1 query_cache_size = 8M query_cache_limit = 2M ft_min_word_len = 4 log_bin = mysql-bin binlog_format = mixed expire_logs_days = 7 #log_error = /var/log/mysql/mysql-error.log slow_query_log = 1 long_query_time = 1 #slow_query_log_file = /var/log/mysql/mysql-slow.log performance_schema = 0 #lower_case_table_names = 1 skip-external-locking default_storage_engine = InnoDB innodb_file_per_table = 1 innodb_open_files = 500 innodb_buffer_pool_size = 64M innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_thread_concurrency = 0 innodb_purge_threads = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 32M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 bulk_insert_buffer_size = 8M myisam_sort_buffer_size = 8M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 interactive_timeout = 28800 wait_timeout = 28800 [mysqldump] quick max_allowed_packet = 500M [myisamchk] key_buffer_size = 8M sort_buffer_size = 8M read_buffer = 4M write_buffer = 4M
然后我们可以使用下面命令启动mysql
docker run -itd -p 3306:3306 --name mysql57 -v /data/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /data/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=admin123 mysql:5.7.28
接着我们写个docker-compose.yml文件,用这个也创建一个试试
cd /data/mysql sudo vim docker-compose.yml version: '2.0' services: mysql57: restart: always image: mysql:5.7.28 ports: - 3306:3306 volumes: - ./conf/my.cnf:/etc/mysql/my.cnf - ./data:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=admin123 - TZ=Asia/Shanghai
