Docker 安装 Redis、mysql

1. docker 安装

1.安装实用工并设置稳定的存储库。

 sudo yum install -y yum-utils
​
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

2.安装最新版本的 Docker 发动机和容器

 sudo yum install -y docker-ce docker-ce-cli containerd.io

3.启动docker

sudo systemctl start docker

4.验证docker启动

sudo docker images
sudo docker -v

5.开启docker服务

sudo systemctl enable docker

6.镜像加速

    sudo mkdir -p /etc/docker 

    sudo tee /etc/docker/daemon.json <<-'EOF'
    { 
    "registry-mirrors": ["https://23391u9p.mirror.aliyuncs.com"] 
    } 
　　EOF 

    sudo systemctl daemon-reload sudo systemctl restart docker

2. docker 服务的安装

 

1.安装 My S Q L 5.7

docker pull mysql:5.7

2.配置 My S Q L 5.7

 docker run -p 3306:3306 --name mysql \
> -v /mydata/mysql/log:/var/log/mysql \
> -v /mydata/mysql/data:/var/lib/mysql \
> -v /mydata/mysql/conf:/etc/mysql \
> -e MYSQL_ROOT_PASSWORD=root \
> -d mysql:5.7

3.查看正在运行的服务

docker ps

4.配置My S Q L 5.7

vim /mydata/mysql/conf/my.cnf

client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection=utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

5.重启My S Q L服务

docker restart mysql

6跟随docker自启动

docker update mysql  --restart=always

1.报错:

IPv4 forwarding is disabled. Networking will not work

2.解决办法:

1.echo "net.ipv4.ip_forward=1" >>/etc/sysctl.conf
2.systemctl restart network && systemctl restart docker
3.sysctl net.ipv4.ip_forward
输出>>net.ipv4.ip_forward = 1

 

2.redis安装

1.
mkdir -p /mydata/redis/conf
2.
touch /mydata/redis/conf/redis.conf
3.
docker run -p 6379:6379 --name redis \
-v /mydata/redis/data:/data \
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf \
-d redis redis-server /etc/redis/redis.conf
4.
docker exec -it redis redis-cli

5跟随docker自启动

docker update redis  --restart=always

1.报错:

IPv4 forwarding is disabled. Networking will not work

2.解决办法:

1.echo "net.ipv4.ip_forward=1" >>/etc/sysctl.conf
2.systemctl restart network && systemctl restart docker
3.sysctl net.ipv4.ip_forward
输出>>net.ipv4.ip_forward = 1
