docker部署redis

1. 拉取鏡像

docker pull redis:7.0.10

2. 拷貝一份redis.conf文件復(fù)制到/home/ubuntu/redis文件夾下，修改redis.conf配置文件

vim redis.conf
-----------------------------------------------------
# 內(nèi)容如下所示
#開啟持久化
appendonly yes
port 6379
#設(shè)置密碼
requirepass 1234
#允許訪問的地址，默認(rèn)是127.0.0.1，會(huì)導(dǎo)致只能在本地訪問。修改為0.0.0.0則可以在任意IP訪問，生產(chǎn)環(huán)境不要設(shè)置為0.0.0.0
bind 0.0.0.0
#默認(rèn)yes，要改為no，也是是保護(hù)模式，限制為本地訪問，修改為no后解除保護(hù)模式
protected-mode no
# 守護(hù)進(jìn)程，修改為yes后即可后臺運(yùn)行，但是這邊需要設(shè)置為no
daemonize no

3. 創(chuàng)建redis容器

docker run -d -p 6379:6379 --restart=always \
-v /home/ubuntu/redis/redis.conf:/etc/redis/redis.conf \
-v /home/ubuntu/redis/data:/data \
--name redis redis:7.0.10 \
redis-server /etc/redis/redis.conf

-------------注釋------------------------
docker run -itd --name redis -p 6379:6379 \
--restart=always \
-v /home/xt/redis/redis.conf:/etc/redis/redis.conf \
-v /home/xt/redis/data:/data \
redis redis-server /etc/redis/redis.conf 

-p 6379:6379：把容器內(nèi)的6379端口映射到宿主機(jī)6379端口
–restart=always：啟動(dòng)docker時(shí)啟動(dòng)該容器
-v /home/xt/redis/redis.conf:/etc/redis/redis.conf：把宿主機(jī)配置好的redis.conf放到容器內(nèi)的這個(gè)位置中
-v /home/xt/redis/data:/data：把redis持久化的數(shù)據(jù)在宿主機(jī)內(nèi)顯示，做數(shù)據(jù)備份
redis-server /etc/redis/redis.conf：按照這個(gè)redis.conf的配置啟動(dòng)

docker部署mysql

MySQL 8.0.30

• 拉取鏡像

docker pull mysql:8.0.30

• 創(chuàng)建容器

systemctl stop mysqld#先暫停mysql服務(wù)
docker run -d --name mysql -p 3306:3306 -v mysql_data:/var/lib/mysql -v mysql_conf:/etc/mysql --restart=always --privileged=true -e TZ=Asia/Shanghai -e MYSQL_ROOT_PASSWORD=1234 mysql:8.0.30#添加一段時(shí)區(qū)

docker安裝完成mysql8，如果使用sqlyog或者navite連接，需要修改密碼加密規(guī)則，因?yàn)榈桶姹究蛻舳斯ぞ卟恢С謒ysql8最新的加密規(guī)則。如果使用客戶端連接，需要修改：

• docker exec 進(jìn)入mysql容器

docker exec -it mysql /bin/bash

• mysql -uroot -p 登錄你的 MySQL 數(shù)據(jù)庫（密碼：1234），然后 執(zhí)行這條SQL：

mysql -u root -p
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '1234';

ubuntu@VM-4-2-ubuntu:~$ sudo docker ps

bash-4.4# mysql -u root -p

bug:連接不上 docker中的mysql

解決：呃呃呃，在服務(wù)器防火墻配置3306端口對外開放…

bug:Access denied for user ‘root’@‘124.160.200.116’ (using password: YES)

原因：mysql中root權(quán)限為localhost，需要?jiǎng)?chuàng)建root@%

docker部署nginx

參考：docker部署nginx

1.拉取鏡像

docker pull nginx

2.啟動(dòng)nginx容器（工具人）

docker run --restart=always --name=nginx -p 80:80 -d nginx

3.訪問測試

訪問地址：http://ip+port

4.掛載準(zhǔn)備

• 宿主機(jī)創(chuàng)建掛載目錄

  mkdir /home/ubuntu/nginx -p
  

• 復(fù)制配置文件到宿主機(jī)

  docker cp nginx:/etc/nginx /home/ubuntu/nginx/conf
  docker cp nginx:/usr/share/nginx/html /home/ubuntu/nginx/html
  docker cp nginx:/var/log/nginx /home/ubuntu/nginx/logs
  

• 刪除之前創(chuàng)建的nginx

  docker stop nginx
  docker rm nginx
  

5.掛載啟動(dòng)nginx容器

docker run --restart=always --name=nginx -p 80:80 \
-v /home/ubuntu/nginx/conf:/etc/nginx \
-v /home/ubuntu/nginx/html:/usr/share/nginx/html \
-v /home/ubuntu/nginx/logs:/var/log/nginx \
-d nginx

6.修改/home/ubuntu/nginx/html/index.html，訪問測試

訪問地址：http://ip+port

注意：在上述操作步驟中，我只將80端口與宿主機(jī)進(jìn)行了映射，也就意味著只能使用80端口訪問nginx,如果要使用nginx啟動(dòng)多個(gè)前端項(xiàng)目的時(shí)候，則需要將容器里的多個(gè)端口映射到宿主機(jī)。有兩種方式可以實(shí)現(xiàn)。
