- 存储 {#3-存储} =============
两种方式，注意区分：
- 目录挂载：
-v /app/nghtml:/usr/share/nginx/html - 卷映射：
-v ngconf:/etc/nginx
docker run -d -p 99:80 \
-v /app/nghtml:/usr/share/nginx/html \
-v ngconf:/etc/nginx \
--name app03 \
nginx
- 网络 {#4-网络} =============
创建自定义网络，实现主机名作为稳定域名访问。
4.1. Redis主从同步集群 {#41-redis主从同步集群}
#自定义网络
docker network create mynet
#主节点
docker run -d -p 6379:6379 \
-v /app/rd1:/bitnami/redis/data \
-e REDIS_REPLICATION_MODE=master \
-e REDIS_PASSWORD=123456 \
--network mynet --name redis01 \
bitnami/redis
#从节点
docker run -d -p 6380:6379 \
-v /app/rd2:/bitnami/redis/data \
-e REDIS_REPLICATION_MODE=slave \
-e REDIS_MASTER_HOST=redis01 \
-e REDIS_MASTER_PORT_NUMBER=6379 \
-e REDIS_MASTER_PASSWORD=123456 \
-e REDIS_PASSWORD=123456 \
--network mynet --name redis02 \
bitnami/redis
4.2. 启动MySQL {#42-启动mysql}
docker run -d -p 3306:3306 \
-v /app/myconf:/etc/mysql/conf.d \
-v /app/mydata:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 \
mysql:8.0.37-debian
- Docker Compose {#5-docker-compose} =====================================
5.1. 命令式安装 {#51-命令式安装}
# 创建网络
docker network create blog
# 启动mysql
docker run -d -p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=123456 \
-e MYSQL_DATABASE=wordpress \
-v mysql-data:/var/lib/mysql \
-v /app/myconf:/etc/mysql/conf.d \
--restart always --name mysql \
--network blog \
mysql:8.0
# 启动wordpress
docker run -d -p 8080:80 \
-e WORDPRESS_DB_HOST=mysql \
-e WORDPRESS_DB_USER=root \
-e WORDPRESS_DB_PASSWORD=123456 \
-e WORDPRESS_DB_NAME=wordpress \
-v wordpress:/var/www/html \
--restart always --name wordpress-app \
--network blog \
wordpress:latest

5.3. 特性 {#53-特性}
-
增量更新
-
- 修改 Docker Compose 文件。重新启动应用。只会触发修改项的重新启动。
-
数据不删
-
- 默认就算down了容器，所有挂载的卷不会被移除。比较安全
- Dockerfile {#6-dockerfile} =============================
打包好jar包，编写Dockerfile文件
FROM openjdk:17
LABEL author=lijing
COPY app.jar /app.jar
EXPOSE 8080
`ENTRYPOINT ["java","-jar","/app.jar"]
`
- 附录 - 一键安装超多中间件 {#7-附录---一键安装超多中间件} =====================================
# Disable memory paging and swapping performance
sudo swapoff -a
# Edit the sysctl config file
sudo vi /etc/sysctl.conf
# Add a line to define the desired value
# or change the value if the key exists,
# and then save your changes.
vm.max_map_count=262144
# Reload the kernel parameters using sysctl
sudo sysctl -p
# Verify that the change was applied by checking the value
cat /proc/sys/vm/max_map_count
7.1. yaml {#71-yaml}
注意：
- 将下面文件中
kafka的119.45.147.122改为你自己的服务器IP。 - 所有容器都做了时间同步，这样容器的时间和linux主机的时间就一致了
准备一个 compose.yaml文件，内容如下：

# 在 compose.yaml 文件所在的目录下执行
docker compose up -d
# 等待启动所有容器
tip：如果重启了服务器，可能有些容器会启动失败。再执行一遍 docker compose up -d即可。所有程序都可运行成功，并且不会丢失数据。请放心使用。
