Docker部署MySQL8数据库

1、准备工作

docker pull mysql:8.0.27
Pwd="/data/software/mysql"
mkdir ${Pwd}/{data,logs} -p
chmod 777 ${Pwd}/logs

2、添加配置文件

cat > ${Pwd}/my.cnf << EOF
[mysqld]
user=mysql
pid-file=/var/run/mysqld/mysqld.pid
socket=/var/run/mysqld/mysqld.sock
datadir=/var/lib/mysql
symbolic-links=0
log-error=/var/log/mysql/mysqld.log
slow_query_log_file=/var/log/mysql/slow.log
secure-file-priv= NULL
skip_ssl
default-time-zone='+8:00'
lower_case_table_names=1
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
log_bin_trust_function_creators=1
event_scheduler=ON
skip_name_resolve
long_query_time=3
slow_query_log=1
innodb_log_buffer_size=16M
innodb_log_file_size=128M
innodb_buffer_pool_size=1024M
key_buffer_size=256M
thread_cache_size=16
wait_timeout=28000
max_connections=1500
open_files_limit=102400
character-set-server=utf8
server_id=1
log-bin=mysqld-bin
default-authentication-plugin=mysql_native_password
explicit_defaults_for_timestamp=1

!includedir /etc/mysql/conf.d/
EOF

3、运行容器

docker run -itd --name mysql \
    -e MYSQL_ROOT_PASSWORD=NTQ34tg*@19VF \
    -v ${Pwd}/my.cnf:/etc/mysql/my.cnf \
    -v ${Pwd}/data:/var/lib/mysql \
    -v ${Pwd}/logs:/var/log/mysql \
    -v /etc/localtime:/etc/localtime \
    -p 3306:3306 \
    --restart=always mysql:8.0.27

4、连接数据库，测试服务是否正常

docker exec -it mysql mysql -uroot -pNTQ34tg*@19VF
