docker安装及微服务镜像安装
docker安装及微服务镜像安装
简述：主要分享docker安装步骤，及微服务组件的镜像安装，如：nacos、seata、elasticsearch、rabbitmq、mongodb、minio…等等
一、docker安装，如果不是root用户，记得命令前加上sudo
1、安装yum工具
yum install -y yum-utils \
device-mapper-persistent-data \
lvm2 --skip-broken
2、更新本地镜像源
yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo
yum makecache fast
3、安装docker
yum install -y docker-ce
4、先关闭防火墙，再启动
# 关闭防火墙
systemctl stop firewalld
# 禁止开机启动防火墙
systemctl disable firewalld
# 查看是否关闭防火墙
systemctl status firewalld
5、启动docker，出现active（running）时，即为启动成功
# 启动docker服务
systemctl start docker
# 停止docker服务
systemctl stop docker
# 重启docker服务
systemctl restart docker
6、查看docker版本
docker -v
7、配置镜像加速
7.1、新建目录
mkdir -p /etc/docker
7.2、/etc/docker下新建文件
touch /etc/docker/daemon.json
7.3、登录阿里云https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors，找到镜像，复制镜像地址
7.4、编辑文件
vim daemon.json
7.5、复制下面内容进去，镜像地址替换成上面复制的
{
"registry-mirrors": ["https://xxxxx.mirror.aliyuncs.com"]
}
7.6、重新加载文件
systemctl daemon-reload
8、重启docker
systemctl restart docker
二、拉取镜像，并安装运行
1.docker常用命令
# 查找镜像
docker search nacos
# 拉取最新镜像
docker pull redis:latest
# 启动容器
docker run elasticsearch
# 停止容器
docker stop elasticsearch
# 查看端口使用
lsof -i:8080
# 查看进程
docker ps
# 删除容器
docker rm 25b7b405f71c
# 删除镜像
docker rmi 5acf0e8da90b
# 设置容器开机自启
docker update redis --restart=always
2、安装nacos
2.1、查找、拉取镜像
docker search nacos
docker pull nacos/nacos-server:latest
2.2、创建目录、文件
mkdir -p /mydata/nacos/logs/
mkdir -p /mydata/nacos/init.d/
touch /mydata/nacos/init.d/custom.properties
2.3、查看mysql在docker中对应的ip，写在下面配置文件中
# mysql是对应的容器名字
docker inspect mysql | grep IPAddress
2.4、编辑custom.properties，复制下面内容进去，修改数据库连接
erver.contextPath=/nacos
server.servlet.contextPath=/nacos
server.port=8848
spring.datasource.platform=mysql
db.num=1
# 这里要对应ip，以及对应的数据库
db.url.0=jdbc:mysql://172.17.0.2:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=root
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i
nacos.security.ignore.urls=/,//*.css,//.js,/**/.html,//*.map,//.svg,/**/.png,//*.ico,/console-fe/public/,/v1/auth/login,/v1/console/health/,/v1/cs/,/v1/ns/,/v1/cmdb/,/actuator/,/v1/console/server/
nacos.naming.distro.taskDispatchThreadCount=1
nacos.naming.distro.taskDispatchPeriod=200
nacos.naming.distro.batchSyncKeyCount=1000
nacos.naming.distro.initDataRatio=0.9
nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true
nacos.naming.expireInstance=true
2.5、启动nacos
docker run --name nacos -p 8848:8848 \
--privileged=true \
--restart=always \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
-e MODE=standalone \
-e PREFER_HOST_MODE=hostname \
-v /mydata/nacos/logs:/home/nacos/logs \
-v /mydata/nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties \
-d nacos/nacos-server
2.6、浏览器访问，账号、密码：nacos
192.168.2.212:8848/nacos
3、安装nginx
3.1、拉取镜像
docker pull nginx:latest
3.2、启动nginx
docker run --name my-nginx -p 80:80 -d nginx
3.3、新建目录
mkdir -p /mydata/nginx/data
mkdir -p /mydata/nginx/config
mkdir -p /mydata/nginx/logs
3.4、停止nginx
docker stop nginx
3.5、删除容器
docker rm nginx
3.6、重新启动nginx
# -v：目录挂载，将data文件夹挂在到指定目录下，将redis.conf挂载到指定目录下
docker run --privileged=true -e TZ="Asia/Shanghai" -it -d --name nginx -p 80:80 \
-v /mydata/nginx/data:/usr/share/nginx/html \
-v /mydata/nginx/config/nginx.conf:/etc/nginx/nginx.conf \
-v /mydata/nginx/config/default.conf:/etc/nginx/conf.d/default.conf \
-v /mydata/nginx/logs:/var/log/nginx nginx
3.7、在/mydata/nginx/data下创建index.html
touch index.html
3.8、编辑index.html，将下面内容复制进去，测试效果
vim index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.content {
margin-top: 20%;
text-align: center;
}
.detail {
font-size: 40px;
font-weight: bold;
font-family: Cursive;
}
</style>
</head>
<body>
<div class="content">
<p class="detail">享清福不在为官，只要囊有钱，仓有米，腹有诗书，便是山中宰相</p>
<p class="detail">祈寿年无须服药，但愿身无病，心无忧，门无债主，可为地上神仙</p>
</div>
</body>
</html>
3.9、浏览器访问
192.168.2.212
4、安装redis
4.1、拉取最新镜像
docker pull redis:latest
4.2、创建redis目录
mkdir -p /mydata/redis/config
mkdir /mydata/redis/data
4.3、挂载redis
touch /mydata/redis/config/redis.conf
4.4、启动redis
# -v：目录挂载，将data文件夹挂在到指定目录下，将redis.conf挂载到指定目录下，实际目录要进入redis中查看（docker exec -it redis bash）
# -p：端口映射，将docker中的6379端口映射到服务器的6379端口上
docker run -p 6379:6379 -v /mydata/redis/data:/data --name redis redis --requirepass 123456 --appendonly yes
4.5、修改redis密码
#1.进入redis的容器
docker exec -it 容器ID bash
#2.进入redis目录
cd /usr/local/bin
#3.运行命令：
redis-cli
#4.查看现有的redis密码：
config get requirepass
#5.设置redis密码
config set requirepass 密码
5、安装mongodb
5.1、拉取镜像
docker pull mongo:latest
5.2、启动mongo，释放 docker的27017端口映射到服务器的27017，–name 要启动的容器名称
docker run -p 27017:27017 --name mongodb -d mongo
5.3、使用 volume 持久化数据
docker run -it -v mongo_volume:/mydata/mongodb/data -p 27017:27017 --name mongodb -d mongo 47bdb045bd0d
5.4、新增用户
进入mongo容器，依次执行命令
# 进入mongo容器
docker exec -it mongodb bash
# 登录mongodb
mongo admin
# 创建一个名为root，密码为123456 的用户
db.createUser(
{
user:"root",
pwd:"123456",
roles:[{role:"root",db:"admin"}]
}
)
# 授权root
db.auth("root","123456")
# 进入数据库bbc_dev
use bbc_dev
# 添加用户
db.createUser(
{
user: "root",
pwd: "123456",
roles: [{role:"readWrite", db: "bbc_dev"}]
}
)
5.4、浏览器访问
http://192.168.2.212:27017/
6、安装mysql
6.0、常见命令
# 进入mysql，修改密码
update user set password=password('root') where user='root';
# 进入mysql，查询最大连接数
show variables like '%max_connections%';
# 容器内部拷贝
docker cp mysql:/etc/mysql/conf.d /mydata/mysql/config
6.1、拉取镜像
docker pull mysql:8.0.20
6.2、新建目录
mkdir -p /mydata/mysql/data
mkdir -p /mydata/mysql/config
mkdir -p /mydata/mysql/logs
6.3、新建文件my.cnf，将配置文件挂载到指定目录下（一致挂载失败，后面再更新）
6.4、启动mysql，有个坑：挂载的目录和文件需要提前创建好，不然挂载失败
docker run --restart=always -d --name mysql -v /mydata/mysql/data:/var/lib/mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root mysql
6.5、进入mysql容器，退出：exit
docker exec -it mysql bash
6.6、登录mysql
mysql -u root -p
6.7、navicat连接测试
7、安装minio
7.1、查找、拉取镜像
docker search minIO
docker pull minio/minio:latest
7.2、创建目录
mkdir -p /mydata/minio/data
7.3、启动minio
docker run -p 9000:9000 -p 9090:9090 \
--name minio \
-d --restart=always \
-e "MINIO_ACCESS_KEY=minioadmin" \
-e "MINIO_SECRET_KEY=minioadmin" \
-v /mydata/minio/data:/data \
minio/minio server \
/data --console-address ":9090" -address ":9000"
7.4、浏览器访问，账号、密码：7.3设置的minioadmin
192.168.2.212:9090
8、安装elasticsearch
8.1、拉取镜像
docker pull elasticsearch:7.8.0
8.2、创建es目录
mkdir /mydata/elasticsearch/config
mkdir /mydata/elasticsearch/data
8.3、授权es
chmod -R 777 /mydata/elasticsearch/
8.4、启动es，挂载elasticsearch.yml到指定目录下（一致挂载失败，后面再更新）
# 将容器中的目录：/data，挂载到本地：/mydata/elasticsearch/data
docker run --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms84m -Xmx512m" \
-v /mydata/elasticsearch/data:/data \
-v /mydata/elasticsearch/plugins:/plugins \
-d elasticsearch:7.8.0
9、安装seata
9.1、查找、拉取seata
docker search seata
docker pull seataio/seata-server:latest
9.2、启动seata
docker run -d --name seata-server -p 8091:8091 seataio/seata-server
9.3、新建目录
mkdir -p /mydata/seata/data
9.4、将seata文件移动到新建目录下
docker cp seata-server:/seata-server /mydata/seata/data
9.5、修改application.yml，在/mydata/seata/data/seata-server/resources下，替换成下面内容
vim /mydata/seata/data/seata-server/resource/application.yml

9.6、查看运行的seata的id，停止容器，删除容器
docker stop a6efab070fc2
docker rm a6efab070fc2
9.7、再次启动seata，SEATA_IP = “你自己的IP”
docker run -d --restart always --name seata-server -p 8091:8091 \
-v /mydata/seata/data/seata-server -e SEATA_IP=192.168.2.212 \

10、安装rabbitMQ
10.1、拉取镜像
docker pull rabbitmq:latest
10.2、运行rabbit，将docker的15672、5672映射到服务器的15672、5673端口
docker run -d --hostname rabbit --name rabbit -p 15672:15672 -p 5673:5672 rabbitmq
10.3、进入rabbit容器，退出：exit
docker exec -it rabbitmq bash
10.4、执行加载配置
