docker tomcat + mysql

Build on a clean CentOS image
Centos image preparation
Pull the Centos image on the virtual machine: docker pull centos
Create a container to run the Centos image: docker run -it -d –name mycentos centos /bin/bash
Note: There is an error here [ WARNING: IPv4 forwarding is disabled. Networking will not work. ]

Change the virtual machine file: vim /usr/lib/sysctl.d/00-system.conf
Add the following content
net.ipv4.ip_forward=1
Restart the network: systemctl restart network
Note: There is another problem here, systemctl in docker can not be used normally. Find the following solutions on the official website

Link: https://forums.docker.com/t/systemctl-status-is-not-working-in-my-docker-container/9075/4

Run mirror with the following statement
docker run –privileged -v /sys/fs/cgroup:/sys/fs/cgroup -it -d –name usr_sbin_init_centos centos /usr/sbin/init

1. Must have –privileged

2. Must have -v /sys/fs/cgroup:/sys/fs/cgroup

3. Replace bin/bash with /usr/sbin/init

Install the JAVA environment
Prepare the JDK tarball to upload to the virtual machine
Put the tarball into the docker container using docker cp
docker cp jdk-11.0.2_linux-x64_bin.tar.gz 41dbc0fbdf3c:/

The same as the linux cp specified usage, you need to add the identifier of the container: id or name

Extract the tar package
tar -xf jdk-11.0.2_linux-x64_bin.tar.gz -C /usr/local/java/jdk
Edit profile file export java environment variable

/etc/profile

export JAVA_HOME=/usr/local/java/jdk/jdk1.8.0_91
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
Run source /etc/profile to make environment variables take effect
Whether the test is successful
java –version

result

java 11.0.2 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)
Install Tomcat
Prepare the tomcat tar package to upload to the virtual machine and cp to the docker container
Extract to
tar -xf apache-tomcat-8.5.38.tar.gz -C /usr/local/tomcat
Set boot boot, by using rc.local file

rc.local Add the following code

export JAVA_HOME=/usr/local/java/jdk/jdk-11.0.2
/usr/local/tomcat/apache-tomcat-8.5.38/bin/startup.sh
Open tomcat

/usr/local/tomcat/apache-tomcat-8.5.38/bin/ directory running
./startup.sh
Detection
curl localhost:8080

?html source content

Install mysql
Get the yum source of mysql
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
Install the above yum source
yum -y install mysql57-community-release-el7-10.noarch.rpm
Yum install mysql
yum -y install mysql-community-server
Change the mysql configuration: /etc/my/cnf
Validate_password=OFF # Turn off password verification
character-set-server=utf8
collation-server=utf8_general_ci
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
Initialize specified but the data directory has files in it # The default behavior of timestamp from 5.6 is already deprecated, need to close the warning

[client]

default-character-set=utf8
Get the mysql initial password

grep “password” /var/log/mysqld.log

[Note] A temporary password is generated for root@localhost: k:nT<dT,t4sF

Use this password to log in to mysql

Go to mysql and proceed

Enter

mysql -u root -p

change the password

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘111111’;

Change to make mysql remote access

update user set host = ‘%’ where user = ‘root’;
Test, you can use physical machine, use navicat to access mysql in docker
Packing container
On the docker hub

Submit the container as a mirror

docker commit -a ‘kane’ -m ‘test’ container_id images_name:images_tag

dockerhub
docker push kane0725/tomcat
Local tarball everywhere

Export to cost tar package

docker export -o test.tar a404c6c174a2

Import the tar package into a mirror

docker import test.tar test_images
Use Dockerfile
Note: only build a mirror of tomcat

Ready to work
Create a special folder and put the jdk and tomcat tarballs
Create a Dockerfile in this directory
Centos base image

Docker build problem
Be sure to bring the order behind. Otherwise it will report an error.
“docker build” requires exactly 1 argument(s).
Run a container

docker run -it –name tomcats –restart always -p 1234:8080 tomcats /bin/bash

/usr/local/tomcat8/bin/startup.sh

Use docker compose
Install docker compose

The way I choose is pip installation

installation

pip install docker-compose

docker-compose –version
