1.1、拉取mysql镜像

[root@iz2zedg4ylq9iqtwm11wecz ~]# dokcer pull mysql:5.7
[root@iz2zedg4ylq9iqtwm11wecz ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/tomcat    latest              c43a65faae57        2 weeks ago         667 MB
docker.io/mysql     5.7                 2c9028880e58        2 weeks ago         447 MB
docker.io/centos    latest              300e315adb2f        5 months ago

1.2、运行容器

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker run --name mysql \
> -p 3316:3306 -d mysql:5.7
e66ce0a9d573fc7434946dd5ce28996769db7c23d888cb039b09ff69d4f9d730

1.2.1、查看容器运行状态

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
e66ce0a9d573        mysql:5.7           "docker-entrypoint..."   42 seconds ago      Exited (1) 41 seconds ago                       mysql

发现mysql已经停止运行

1.2.2、通过docker logs 容器id查看容器运行日志

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker logs e66ce0a9d573
2021-05-28 07:42:18+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 5.7.34-1debian10 started.
2021-05-28 07:42:18+00:00 [Note] [Entrypoint]: Switching to dedicated user 'mysql'
2021-05-28 07:42:18+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 5.7.34-1debian10 started.
2021-05-28 07:42:18+00:00 [ERROR] [Entrypoint]: Database is uninitialized and password option is not specified
    You need to specify one of the following:
    - MYSQL_ROOT_PASSWORD
    - MYSQL_ALLOW_EMPTY_PASSWORD
    - MYSQL_RANDOM_ROOT_PASSWORD
[root@iz2zedg4ylq9iqtwm11wecz ~]#

百度翻译得知我们初始化启动mysql的时候，需要指定密码

windows系统搭建docker swarm集群_redis

1.2.3、查看官网使用教程

windows系统搭建docker swarm集群_mysql_02

#我们需要这样run mysql
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker run --name mysql -p 3316:3306 -d -e MYSQL_ROOT_PASSWORD=123 mysql:5.7
0d2eb32cb4ae320e9f3e1365eea04a262667b711a878b661905ccb083706a949
[root@iz2zedg4ylq9iqtwm11wecz ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
0d2eb32cb4ae        mysql:5.7           "docker-entrypoint..."   7 seconds ago       Up 6 seconds        33060/tcp, 0.0.0.0:3316->3306/tcp   mysql
[root@iz2zedg4ylq9iqtwm11wecz ~]#

这个时候mysql就启动成功了

1.2.4、我们测试连接一下这个mysql

1.2.4.1、本地连接：

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker exec -it 0d2eb32cb4ae /bin/bash
root@0d2eb32cb4ae:/# mysql -u root -p
Enter password:

mysql>

1.2.4.2、远程连接：

windows系统搭建docker swarm集群_mysql_03

可以发现我们已经成功连接上使用docker安装的mysql

1.3、登录mysql后我们还需要更改mysql的一些默认配置

我们可以查看官网是如何更改默认配置的

windows系统搭建docker swarm集群_docker_04

我们先将MySQL的配置文件复制到宿主主机

[root@iz2zedg4ylq9iqtwm11wecz conf]# docker cp mysql:/etc/mysql/mysql.conf.d/mysqld.cnf /my/mysql/conf
[root@iz2zedg4ylq9iqtwm11wecz conf]# ls
mysqld.cnf
[root@iz2zedg4ylq9iqtwm11wecz conf]#

1.3.1、我们重新run一个mysql容器

在run mysql容器的时候我们需要挂载一些数据、日志和配置。防止容器停止运行和数据丢失

第一步是在我们的宿主主机创建好mysql存放数据、日志和配置的目录

[root@iz2zedg4ylq9iqtwm11wecz my]# mkdir -p mysql/conf
[root@iz2zedg4ylq9iqtwm11wecz my]# mkdir -p mysql/data
[root@iz2zedg4ylq9iqtwm11wecz my]# mkdir -p mysql/logs
[root@iz2zedg4ylq9iqtwm11wecz my]# ls
mysql
[root@iz2zedg4ylq9iqtwm11wecz my]# cd mysql
[root@iz2zedg4ylq9iqtwm11wecz mysql]# ls
conf  data  logs
[root@iz2zedg4ylq9iqtwm11wecz mysql]#

删除并重新run mysql

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker run --name mysql \
-p 3316:3306 \
-v /my/mysql/conf:/etc/mysql/mysql.conf.d/ \
-v /my/mysql/data:/var/lib/mysql \
-v /my/mysql/logs:/logs \
-e MYSQL_ROOT_PASSWORD=123 \
-d mysql:5.7
9d55c43331202d784d14e49f685aa633ddee525b59eb2c3067e607a335fbf739

更改默认配置文件

[root@iz2zedg4ylq9iqtwm11wecz conf]# pwd
/my/mysql/conf
[root@iz2zedg4ylq9iqtwm11wecz conf]# vim mysqld.cnf

更改默认的字符集**(注意更改配置文件后要重启容器才能生效)**

windows系统搭建docker swarm集群_mysql_05

进入mysql查看字符集是否修改成功（注意更改配置文件后需要重启容器）

mysql> create database m
    -> ;
Query OK, 1 row affected (0.00 sec)

mysql> show create database m
    -> ;
+----------+------------------------------------------------------------+
| Database | Create Database                                            |
+----------+------------------------------------------------------------+
| m        | CREATE DATABASE `m` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+----------+------------------------------------------------------------+
1 row in set (0.00 sec)

2、安装redis

2.1、拉取镜像

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker pull redis
Using default tag: latest
Trying to pull repository docker.io/library/redis ...

docker.io/mysql     5.7                 2c9028880e58        2 weeks ago         447 MB
docker.io/centos    latest              300e315adb2f        5 months ago        209 MB
[root@iz2zedg4ylq9iqtwm11wecz ~]#

2.2、查看官网使用说明

windows系统搭建docker swarm集群_docker_06

2.3、先去redis的官方网站获取redis.conf配置文件

windows系统搭建docker swarm集群_mysql_07

先下载redis

[root@iz2zedg4ylq9iqtwm11wecz my]# mkdir redis
[root@iz2zedg4ylq9iqtwm11wecz my]# ls
mysql  redis
[root@iz2zedg4ylq9iqtwm11wecz my]# cd redis/
[root@iz2zedg4ylq9iqtwm11wecz redis]# pwd
/my/redis
[root@iz2zedg4ylq9iqtwm11wecz redis]# wget https://download.redis.io/releases/redis-6.2.3.tar.gz

[root@iz2zedg4ylq9iqtwm11wecz redis]#

解压

[root@iz2zedg4ylq9iqtwm11wecz redis]# ls
redis-6.2.3.tar.gz
[root@iz2zedg4ylq9iqtwm11wecz redis]# tar zxf redis-6.2.3.tar.gz 
[root@iz2zedg4ylq9iqtwm11wecz redis]# ls
redis-6.2.3  redis-6.2.3.tar.gz
[root@iz2zedg4ylq9iqtwm11wecz redis]#

获取redis.conf配置文件

[root@iz2zedg4ylq9iqtwm11wecz redis]# cd redis-6.2.3
[root@iz2zedg4ylq9iqtwm11wecz redis-6.2.3]# ls
00-RELEASENOTES  CONTRIBUTING  INSTALL    README.md   runtest-cluster    sentinel.conf  TLS.md
BUGS             COPYING       Makefile   redis.conf  runtest-moduleapi  src            utils
CONDUCT          deps          MANIFESTO  runtest     runtest-sentinel   tests
[root@iz2zedg4ylq9iqtwm11wecz redis-6.2.3]# mkdir /my/redis/conf
[root@iz2zedg4ylq9iqtwm11wecz redis-6.2.3]# cp redis.conf /my/redis/conf
[root@iz2zedg4ylq9iqtwm11wecz redis-6.2.3]# cd /my/redis/conf
[root@iz2zedg4ylq9iqtwm11wecz conf]# ls
redis.conf
[root@iz2zedg4ylq9iqtwm11wecz conf]#

修改配置文件
首先 vim redis.conf
然后，在normal模式（也就是不能写的模式下）下按下/即可进入查找模式按n搜索下一条，N是上一条
搜索：recuirepass （将注释去掉）然后在后面填写密码。比如更改为： requirepass 123

2.4、docker run redis

[root@iz2zedg4ylq9iqtwm11wecz redis]# docker run --name myredis \
> -p 6379:6379 \
> -v /my/redis/conf/redis.conf:/usr/local/etc/redis/redis.conf \
> -v /my/redis/data:/data \                                                                  
> -d redis redis-server /usr/local/etc/redis/redis.conf
598fef497cec840fff08dd5532fbf30f671eeb6022f93c2276cc12b77bc5e548
[root@iz2zedg4ylq9iqtwm11wecz redis]#

2.5、访问 redis

2.5.1本地访问

[root@iz2zedg4ylq9iqtwm11wecz redis]# docker exec -it myredis /bin/bash
root@598fef497cec:/data# redis-cli
127.0.0.1:6379> set name lihua
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123
OK
127.0.0.1:6379> set name lihua
OK
127.0.0.1:6379> set age 18
OK
127.0.0.1:6379> key *
(error) ERR unknown command `key`, with args beginning with: `*`, 
127.0.0.1:6379> keys *
1) "name"
2) "age"
127.0.0.1:6379>

2.5.2远程访问，由于没有安装redis就演示了

注意远程连接需要，在redis.conf配置远程连接。配置文件更改后需要重启容器

1、关闭只允许本机访问

windows系统搭建docker swarm集群_docker_08

2、关闭保护模式

windows系统搭建docker swarm集群_docker_09

2.6、redis在容器中的安装目录

root@0bee7c2d98cb:/usr/local/bin# pwd
/usr/local/bin

3、安装Nginx

3.1、拉取镜像

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/nginx     latest              d1a364dc548d        2 days ago          133 MB

3.2、运行容器

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker run --name mynginx -d nginx
66f66c0d71a6bc73b5af1efe29db0923e70ec80c211b5fba47edf1206f7e0d77
[root@iz2zedg4ylq9iqtwm11wecz ~]#

3.3、在宿主主机创建挂载目录

[root@iz2zedg4ylq9iqtwm11wecz ~]# cd /my/nginx/
[root@iz2zedg4ylq9iqtwm11wecz nginx]# ls
html
[root@iz2zedg4ylq9iqtwm11wecz nginx]# pwd
/my/nginx
[root@iz2zedg4ylq9iqtwm11wecz nginx]#

3.4、从容器中拷贝配置文件

[root@iz2zedg4ylq9iqtwm11wecz nginx]# docker cp mynginx:/etc/nginx/nginx.conf /my/nginx  #主配置文件
[root@iz2zedg4ylq9iqtwm11wecz nginx]# ls
html  nginx.conf
[root@iz2zedg4ylq9iqtwm11wecz nginx]#
[root@iz2zedg4ylq9iqtwm11wecz nginx]# docker cp mynginx:/etc/nginx/conf.d /my/nginx #拷贝nginx 导入虚拟主机配置文件
[root@iz2zedg4ylq9iqtwm11wecz nginx]# ls
conf.d  html  nginx.conf
[root@iz2zedg4ylq9iqtwm11wecz nginx]#

自定义nginx主页

[root@iz2zedg4ylq9iqtwm11wecz nginx]# echo welcome to nginx! > /my/nginx/html/index.html
[root@iz2zedg4ylq9iqtwm11wecz nginx]# cd html
[root@iz2zedg4ylq9iqtwm11wecz html]# cat index.html 
welcome to nginx!
[root@iz2zedg4ylq9iqtwm11wecz html]#

3.5、运行容器

[root@iz2zedg4ylq9iqtwm11wecz nginx]# docker run --name mynginx \
-p 80:80 -p 443:443 \
-v /my/nginx/nginx.conf:/etc/nginx/nginx.conf \
-v /my/nginx/html:/usr/share/nginx/html:ro \
-v /my/nginx/conf.d:/usr/nginx/conf.d \
-d nginx 
dfabf4da2bddc13ee408897d1dac6f3478d30dd6829eda10bb764b46c733de48
[root@iz2zedg4ylq9iqtwm11wecz nginx]#

访问一下

windows系统搭建docker swarm集群_mysql_10

4、安装zookeeper

4.1、搜索镜像

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker search zookeeper

4.3、docker run 镜像名（运行得到一个容器）

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker run -p 2181:2181 --name myzk -d c83b9da01e73
fdf44d05a275ab198f84aeeb95060f17d2d680aed7a1d975c199e335ec4c3751

4.4、启动并打开zk容器

[root@iz2zedg4ylq9iqtwm11wecz ~]# docker start myzk
myzk
[root@iz2zedg4ylq9iqtwm11wecz ~]# docker exec -it myzk /bin/bash
root@fdf44d05a275:/apache-zookeeper-3.7.0-bin#

4.5、运行zk

root@fdf44d05a275:/apache-zookeeper-3.7.0-bin# cd bin
root@fdf44d05a275:/apache-zookeeper-3.7.0-bin/bin# ./zkCli.sh

测试：

[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]
[zk: localhost:2181(CONNECTED) 1]

4.6、外部访问

放行阿里云端口

windows系统搭建docker swarm集群_redis_11

放行服务器内部端口

# 查看防火墙是否运行
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --state
running
# 查询端口号是否放行
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --query-port=8080/tcp
yes
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --query-port=2181/tcp
no 
# 放行端口号， --zone=public 放行类型（public 全部人）port=2181/tcp（放行的端口号：和协议类型） --permanent（永久生效，重启服务器也生效）
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --zone=public --add-port=2181/tcp --permanent
success
# 重新启动防火墙，
[root@iz2zedg4ylq9iqtwm11wecz ~]# systemctl restart firewalld.service
# 重新加载防火墙配置
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --reload
success
[root@iz2zedg4ylq9iqtwm11wecz ~]# firewall-cmd --query-port=2181/tcp
yes
[root@iz2zedg4ylq9iqtwm11wecz ~]#
