2. 案例二 整套项目多容器分离通过docker-compose部署lanmt环境
详细的安装准备环境，省略，配置以及部署参考案例一即可 即可实现批量创建web，也可以实现多web共用一个php或mysql容器
2.1 目录路径的案例
[root@localhost compose_lanmt]# pwd
/app/docker_web/compose_lanmt
[root@localhost compose_lanmt]# ll

2.2 nginx的Dockerfile文件配置
注意： 和lnmp里面的dockerfile相同
进入到nginx目录下配置
将需要安装的nginx包，放入到nginx指定目录下

注：通过此镜像编译后，可直接启动无需挂载配置文件，若有需要，根据自己需要进行挂载配置,也可以编译自己想要编译的版本2.4 tomcat的Dockerfile文件配置
进入到tomcat的目录
将需要的源码包 jdk和tomcat包，放入到tomcat目录下
或者，jdk环境，用物理机上面的，做一下挂载即可,考虑到jdk包比较大

2.5 mysql的Dockerfile文件配置
注意：mysql的Dockerfile 可以自己编译，亦可以用镜像直接启动即可，方法和lnmp里面的安装启动方法是一样的
进入到mysql目录
mkdir -p conf data
再进入到conf目录下，配置my.cnf文件
cat my.cnf
[mysqld]
user=mysql
port=3306
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
pid-file=/var/run/mysql/mysql.pid
log_error=/var/log/mysql/error.log
character_set_server = utf8

docker-compose.yml 文件所在位置和nginx，myslq，tomcat目录同级
管理多个容器的工具，执行一条命令即可安装启动多个容器
- docker-copose-lanmt.yml配置如下
cat docker-compose.yml

下载地址：
https://cdn.mysql.com/Downloads/Connector-J/mysql-connector-java-5.1.47.tar.gz
注意：
1） 编写yml文件和tomcat的Dockerfile的时候，需要注意下，jdk的环境变量
2） 默认如上安装后，是连接不上数据库的，需要一个连接数据库的jar包，mysql-connector-java-5.1.31.jar，上传到tomcat/lib下面
3） 修改数据库的连接配置
eg： 配置数据库如下
cat db.properties
jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://mysql:3306/gongyike?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&zeroDateTime\
Behavior=convertToNull
jdbc.username = root
jdbc.password = 123456
jdbc.maxActive = 100
jdbc.maxWait = 20000
jdbc.maxIdle = 2000
jdbc.defaultAutoCommit = false
jdbc.minPoolSize = 10
jdbc.maxPoolSize = 100
jdbc.acquireIncrement = 3
jdbc.initialPoolSize = 20
注意：数据库连接的配置文件，主机名有三种配置方法，均能实现
- 通过mysql的容器名来连接
- 通过mysql容器的主机名连接
- 通过映射到宿主机的端口来连接
如上面的配置，端口前面的mysql，为容器主机名
2.7 启动lnmt环境
启动方法雷同 lanmp 的启动
前台执行：
docker-compose -f docker-compose.yml up
后台执行：
docker-compose -f docker-compose.yml up -d
常用命令：（省略-f）
docker-compose rm/down/pause/unpause/stop/start/restart/logs/up
删除所有未被任何容器关联引用的卷“
docker volume rm $(docker volume ls -qf dangling=true)
删除所有已退出的容器
docker rm -v $(docker ps -aq -f status=exited)
删除所有状态为dead的容器
docker rm -v $(docker ps -aq -f status=dead)
