Reminder: The following is the main text of this article, and the Docker series of learning will continue to be updated
1. Deploy MySQL
①Search and pull the mysql image
docker search mysql docker pull mysql:5.7
②Create container directory mapping
# Create a mysql directory under the /root/docker-data directory mkdir ~/docker-data/mysql cd ~/docker-data/mysql
③Create and start the container, set port mapping: $PWD indicates the current host location, ie /root/docker-data/mysql
docker run -id \ -p 3307:3306 \ --name=c_mysql \ -v $PWD/conf/my.cnf:/etc/mysql/my.cnf \ #Custom configuration file path, don't write if you don't need it -v $PWD/conf/conf.d:/etc/mysql/conf.d \ -v $PWD/logs:/var/log/mysql \ -v $PWD/data:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=123456 \ #Initialize root user password mysql:5.7
Customize the content of my.cnf as follows:
[mysqld] user=mysql character-set-server=utf8 default_authentication_plugin=mysql_native_password secure_file_priv=/var/lib/mysql sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION max_connections=1000 default-time-zone='+08:00' innodb_buffer_pool_size = 128M port = 3306 datadir=/var/lib/mysql socket=/var/run/mysqld/mysqld.sock pid-file=/var/run/mysqld/mysqld.pid # Number of connection failures allowed. max_connect_errors=10 #engine default-storage-engine=INNODB log-bin = mysql-bin # #Set save time expire_logs_days=7 # #Note that this item needs to be configured for 5.7 and later versions: server-id=123454 (custom, uniqueness guaranteed); server-id generally goes to the last three digits of ip server-id=1 # #binlog format, there are 3 kinds of statement, row, mixed binlog-format=ROW # #Indicates that every time a write is performed, it will be synchronized with the hard disk, which will affect performance. When it is 0, it means that mysql will not perform disk flushing when the transaction is submitted, and it is determined by the system sync-binlog=1 # ## Turn on slow sql slow_query_log=on slow_query_log_file=/var/lib/mysql/slow-query.log long_query_time=1 [client] default-character-set=utf8 [mysql] default-character-set=utf8
④Enter the container and operate mysql
docker exec -it c_mysql /bin/bash mysql -uroot -p123456
⑤Use an external machine to connect to mysql in the container

2. Deploy Tomcat
①Search and pull tomcat image
docker search tomcat docker pull tomcat:8
②Create container directory mapping
# Create a tomcat directory under the /root/docker-data directory mkdir ~/docker-data/tomcat cd ~/docker-data/tomcat
③Create and start the container, set port mapping
docker run -id --name=c_tomcat \ -p 8080:8080 \ -v $PWD:/usr/local/tomcat/webapps \ tomcat:8
④ Use an external machine to access tomcat
pwd # /root/docker-data/tomcat mkdir test cd test touch a.html vim a.html # <h1>Hello, I am dockerCloud tomcat<h1>

3. Deploy Nginx
①Search and pull nginx image
docker search nginx docker pull nginx
②Create container directory mapping
# Create nginx directory in /root/docker-data directory to store nginx data information mkdir ~/docker-data/nginx cd ~/docker-data/nginx
mkdir conf cd conf # Create nginx.conf file under conf, paste the following content vim nginx.conf
Official nginx.conf configuration file:
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {<!-- -->
worker_connections 1024;
}
http {<!-- -->
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request"'
'$status $body_bytes_sent "$http_referer"'
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
③Create and start the container, set port mapping
docker run -id --name=c_nginx \ -p 80:80 \ -v $PWD/conf/nginx.conf:/etc/nginx/conf.d/default.conf \ -v $PWD/logs:/var/log/nginx \ -v $PWD/html:/usr/share/nginx/html\ nginx
④ Use an external machine to access nginx
a. At this time, the html directory of nginx is empty, and there is no proxy.
b. Call the index.html file in your own html directory
c. Use nginx as a reverse proxy
?If nginx acts as a proxy host application, please refer to: Linux installation nginx detailed tutorial nginx as a reverse proxy.
?If nginx wants to proxy applications in other containers, please refer to: Docker Compose builds multi-container applications and arranges Nginx + Springboot projects.

4. Deploy Redis
①Search and pull the redis image
docker search redis docker pull redis:4.0
②Create container directory mapping
mkdir ~/docker-data/redis cd ~/docker-data/redis
③Create and start the container, set port mapping
You can start directly without mounting the data volume:
docker run -id --name=c_redis -p 6379:6379 redis:4.0
Mount the data volume:
docker run -id --name=c_redis\ -p 6379:6379 \ -v /$PWD/conf/redis.conf:/etc/redis.conf \ -v /$PWD/data:/data \ redis:4.0
Before starting, add /redis/conf/redis.conf custom configuration file to the host:
bind 0.0.0.0 port 6379 daemonize yes logfile "6379.log" dir /data databases 16 # rdb related configuration dbfilename dump-6379.rdb # Compress data when rdb is saved rdbcompression yes # rdb file format verification rdb checksum yes stop-writes-on-bgsave-error yes save 10 2 # aof related configuration append only yes appendfsync always appendfilename appendonly-6379.aof
④Use an external machine to connect to redis
redis-cli.exe -h 1.15.76.95 -p 6379

Tip: Here is a summary of the article:
This article is a study of Docker, learned how to deploy applications in Docker, and deployed our commonly used development tools such as mysql, tomcat, nginx, redis, and configured data volumes for them. The following learning content will continue to be updated! ! !
