云原生学习（四）

（一）docker redis 主从配置
1.创建文件夹

mkdir /root/data/redis/master/data
touch /root/data/redis/master/redis.conf

mkdir /root/data/redis/slave-1/data
touch /root/data/redis/slave-1/redis.conf

2.yum install redis redis-server -y 将/etc/redis.conf 复制到
修改

bind 0.0.0.0
daemonize no
requirepass 123456
appendonly yes

（从节点修改 masterauth 123456 replicaof 172.17.0.2 6379 ）

3.运行容器

docker run -p 16379:6379 --name redis-master -v /root/data/redis/master/data/:/data -v /root/data/redis/master/redis.conf:/etc/redis/redis.conf -d redis redis-server /etc/redis/redis.conf 

docker run -p 26379:6379 --name redis-slave-1 -v /root/data/redis/slave-1/data/:/data -v /root/data/redis/slave-1/redis.conf:/etc/redis/redis.conf -d redis redis-server /etc/redis/redis.conf 

4.验证

docker exec -it redis-master redis-cli
role
info replication

5.验证不成功

docker exec -it redis-slave redis-cli
slaveof 172.17.0.2 6379

------------------------------docker部署

docker 搭建修改为清华源

2  yum install -y yum-utils device-mapper-persistent-data lvm2
3  yum-config-manager --add-repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo


4  yum repolist
5  yum -y install docker-ce
6  systemctl start docker
7  systemctl status docker
8  docker -v

10 cat /etc/docker/daemon.json
{
"registry-mirrors":["https://mirrors.tuna.tsinghua.edu.cn/"]
}
（二）docker容器部署
docker search portainer
docker pull 6053537/portainer-ce

docker run -d -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock 6053537/portainer-ce
（三）解决bin-log
1）log-bin=mysql-bin
2）set global binlog_format=ROW;
3）systemctl restart mariadb
