1. 案例一整套項目多容器分離經過docker-compose部署lanmp環境

docker網絡關係

同一網段之間容器互通，不一樣網絡之間容器相互隔離，好比，docker0網段和docker1網段內的容器；
不一樣網段內的容器若是想要互通，能夠經過映射到物理網卡上的端口來進行通訊，也是能夠的；

1.1 介紹

compose 是一個定義和管理多容器的工具，使用python語言編寫。使用compose配置文件描述多個容器應用的架構，好比使用什麼鏡像，數據卷，網絡，映射端口等；而後一條命令管理全部服務，好比啓動，中止，重啓等。html

1.2 安裝docker環境

參考網址
https://docs.docker.com/install/linux/docker-ce/centos/node

參考網址
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager    --add-repo   https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl start docker
systemctl enable docker

docker tab鍵自動補全
yum install -y bash-completion
source /usr/share/bash-completion/completions/docker
source /usr/share/bash-completion/bash_completion

注意：
a）修改docker默認的安裝路徑
# vim /lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd  --graph /app/docker

b）修改默認的網絡地址段
# vim /etc/docker/daemon.json
{"bip":"192.168.10.1/24"}
{"icc": false}

注： docker的版本從2017年3月份開始，以年月份來展現版本，而且分爲企業版和社區版

1.3 安裝docker-compose

下載網址
https://github.com/docker/compose/releasespython

安裝步驟：mysql

curl -L https://github.com/docker/compose/releases/download/1.23.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose   
chmod +x /usr/local/bin/docker-compose

1.5 nginx 的Dockerfile文件的編寫

進入到nginx的目錄
將下載好的nignx源碼包，放入到nginx目錄下面linux

cat Dockerfilenginx

FROM       centos:7
MAINTAINER Mr.JingWen
RUN        yum install -y wget telnet vim iproute  iputils  gcc gcc-c++ make openssl-devel pcre pcre-devel

ENV        TZ="Asia/Shanghai"  nginx_v="1.14.2"  soft_sign="PXJY_WebSer"  nginx_dir="/usr/local/nginx"
ADD        source_file/nginx-${nginx_v}.tar.gz /usr/local/src/
# 隱藏服務和版本號
#注意: 若nginx的版本不是 1.14.2 ，須要修改 nginx.h 裏面的版本號，使其對應
COPY       source_file/nginx.h                         /usr/local/src/nginx-${nginx_v}/src/core/
COPY       source_file/ngx_http_header_filter_module.c /usr/local/src/nginx-${nginx_v}/src/http/
COPY       source_file/ngx_http_special_response.c     /usr/local/src/nginx-${nginx_v}/src/http/

           &&  ./configure --prefix=${nginx_dir}  --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module \
           --with-http_gzip_static_module --with-pcre     \
           && make -j 4 && make install
RUN        rm -rf /usr/local/src/nginx-${nginx_v}* && yum clean all
RUN        chown  -R nginx ${nginx_dir}  &&  rm -rf /usr/local/src/nginx-${nginx_v}
WORKDIR    ${nginx_dir}
EXPOSE     80
CMD        ["./sbin/nginx", "-g", "daemon off;"]

備註：此處啓動用本身建立的普通用戶啓動，可是考慮到和宿主機的用戶避免衝突，因此指定了uid，受權的時候須要注意下，建議最好用uid號進行受權。
     經過此編譯文件編譯後可直接啓動，根據本身需求掛載配置文件。

1.7 mysql的Dockerfile文件的配置

mysql的編寫，略，直接下載鏡像啓動便可
進入到mysql目錄

mkdir -p   conf data

再進入到conf目錄下，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
max_connections=3600

1.8 docker-compose YML文件格式以及編寫注意事項

YML數據結構經過縮進來表示，連續的項目經過減號來表示，鍵值對用冒號分隔，數組用中括號括起來，hash用花括號括起來。

YML文件格式注意事項：
1.3.1 不支持製表符tab鍵縮進，須要使用空格縮進
1.3.2 一般開頭縮進2個空格
1.3.3 字符後縮進1個空格，如冒號，逗號，橫槓
1.3.4 用井號註釋
1.3.5 若是包含特殊字符用單引號引發來
1.3.6 布爾值(true,false,yes,no,on,off)必須用引號括起來，這樣分析器會將他們解釋爲字符串。

1.9 docker-compose配置文件經常使用字段

配置文件經常使用字段：

字段	描述
build dockerfile context	指定Dockerfile文件名構建鏡像上下文路徑
image	指定鏡像
command	執行命令，覆蓋默認命令
container_name	指定容器名稱，因爲容器名稱是惟一的，若是指定自定義名稱，則沒法scale
deploy	指定部署和運行服務相關配置，只能在Swarm模式使用
enviroment	添加環境變量
networks	加入網絡，引入自定義網絡
ports	暴露端口，與-p相同，但端口不能低於60
volumes	掛載宿主機路徑或命名卷。若是是命令卷在頂級volumes定義卷名稱
restart	重啓策略，默認no，此參數的做用是是否隨着docker服務自啓動，可選always/on-failure/unless-stopped
hostname	容器主機名

經常使用命令：

字段	描述
build	從新構建服務
ps	列出容器
up	建立和啓動容器，通常和 -d 結合使用，一個是前臺運行，一個是後臺運行
exec	在容器裏執行命令
scale	指定一個服務容器啓動數量
top	顯示容器進程
logs	查看容器輸出
down	刪除容器，網絡，數據卷和鏡像
stop/start/restart	中止/啓動/重啓服務
config	驗證並查看撰寫文件

1.10 docker-copose.yml配置文件

此配置是管理多容器的一個工具

修改默認的網絡名稱

# echo 'export COMPOSE_PROJECT_NAME="compose"' >> /etc/profile

eg: docker 網絡名稱類型以下
# docker network ls
ec4609c83ee5        compose_lanmp                   bridge              local

注意： networks 下面的lanmp 是 新建立的網絡，將整套業務類型，都放在了同一個網絡下面；
      利用lnmp環境時，必定要記住，nginx下面映射的目錄必定也要在php服務下面作相同的映射，不然php解析不到文件

1.11 啓動容器工具進行安裝

docker-compose.yml文件見 1.5
注意：經過 docker-compose.yml文件來建立容器，默認是會執行 docker-compose.yml文件，若是是默認的文件，能夠省略掉 "-f docker-compose.yml"，若是是其餘的yml文件，或者路徑不在當前路徑下，須要用 -f 指定一下

前臺執行：
docker-compose -f docker-compose.yml up
後臺執行：
docker-compose -f docker-compose.yml up -d  

重啓單個容器
docker-compose -f docker-compose.yml  restart  <Service_name>
