Detailed process analysis of docker deployment of snail cinema system

Environmental Statement

Host OS: Cetnos7.9 Minimum installation
docker Version: 20.10.6
System requirements: CPU 2 cores or above, 8G memory

If the number of CPU cores is less than 2, the theater will not be able to log in

mysql database: mysql5.6 container
redis database: redis4.0 container

Install centos7.9

First stop the firewall and turn off SELinux

Check the firewall status

firewall-cmd --state
# or systemctl status firewalld.service

Stop the firewall

systemctl stop firewalld.service

Disable firewall startup

systemctl disable firewalld.service

Permanently disable selinux (optional)

Enter the /etc/selinux/config file

vi /etc/selinux/config

Change SELINUX=enforcing to SELINUX=disabled

Disable SELinux service

setenforce 0

Check SELinux status

sestatus

Install dependency packages

# Install redhat-lsb
yum install -y redhat-lsb
# Install yum-config-manager, otherwise it will report: yum-config-manager: command not found yum -y install yum-utils
# Snail Ticketing depends on net-tools
yum install net-tools -y

Install Docker on CentOS 7.9

# Configure aliyun's docker installation source yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

Install Docker dependencies

yum install -y yum-utils device-mapper-persistent-data lvm2

Check the docker version in the installation source

yum list docker-ce --showduplicates | sort -r

Install the latest version of Docker (20.10.6)

yum install docker-ce -y

Check the Docker version

docker version

Configure Docker image aliyun accelerator

# Create the /etc/docker directory mkdir -p /etc/docker

#Edit and create daemon.json
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://isdp30x2.mirror.aliyuncs.com"]
}
EOF

Restart the Docker daemon

# Restart the daemon process sudo systemctl daemon-reload
# Restart the docker service sudo systemctl restart docker 
# Set Docker to start automatically at boot systemctl enable docker

Deploy redis in docker

Create a local mount directory

mkdir /data/redis/{conf,data} -p

Create a redis container

# First enter the /data/redis/directory cd /data/redis

# Create and run a container named myredis docker run -itd --name myredis \
-p 6379:6379 \
-v /data/redis/data:/data \
--restart always redis --appendonly yes --requirepass "123456"

# Parameter explanation -d -> Start the container as a daemon -p 6379:6379 -> Bind to host port, 6379 host port, 6379 container port --name myredis -> Specify container name --restart always -> Start at boot# --privileged=true -> Increase permissions in the container --requirepass -> Set login password -v /data/redis/data:/data -> Map data directory --appendonly yes -> Enable data persistence

Docker deployment of mysql5.6

Docker runs mysql and persists data

Pull the mysql5.6 image:

docker pull mysql:5.6

Create a mysql local data storage mapping directory:

#MySQL's default data directory is /var/lib/mysql/
#Configure foldersudo mkdir -p /data/mysql/conf
## Create a persistent data folder for mysql data sudo mkdir -p /data/mysql/data
## Create a mysql log folder sudo mkdir -p /data/mysql/logs

## Create mkdir /data/mysql/{conf,data,logs} -p at one time

Running the MySQL container

docker run -dti -p 3306:3306 --name mysql56 -v /data/mysql/conf:/etc/mysql/conf.d -v /data/mysql/logs:/logs -v /data/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Woniu123 --restart=always mysql:5.6

Use navicat to connect to the database, restore the database character encoding to utf8mb4 , and sort by default

Install jdk8 on the host

1. Download JDK8 from the official website

Address: http://www.oracle.com/technetwork/articles/javase/index-jsp-138363.html

Select the corresponding .gz package to download

2. Unzip and put it in the specified directory (take jdk-7u60-linux-x64.gz as an example)

Create a directory:

sudo mkdir /usr/lib/jvm

Unzip to the specified directory:

 sudo tar -zxvf jdk-7u60-linux-x64.gz -C /usr/lib/jvm

3. Modify environment variables:

sudo vim ~/.bashrc

Append the following to the end of the file:

#set oracle jdk environment

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_60 ## Note that the directory should be changed to the JDK directory you unzipped export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib export PATH=${JAVA_HOME}/bin:$PATH

Make the environment variable take effect immediately

 source ~/.bashrc

Check whether jdk is effective

# View the java main program directory which java
# Check the java version java -version

Upload the server program qianyao directory to the host machine's /opt directory

Start the Cinema Server

cd /opt/qianyao
# Start the server./qianyao.sh start all
# Wait for all 10 service programs to start, which takes about two minutes
