docker安裝tomcat8並實現目錄映射端口映射

---

以CentOS7爲例，
先安裝docker
再拉取tomcat
然後配置tomcat容器

docker安裝tomcat8並實現目錄映射端口映射

• 卸載舊版本
  舊版本的 Docker 稱爲 docker 或者 docker-engine ，使用以下命令卸載舊版本：

yum remove docker \
    docker-client \
    docker-client-latest \
    docker-common \
    docker-latest \
    docker-latest-logrotate \
    docker-logrotate \
    docker-selinux \
    docker-engine-selinux \
    docker-engine

• 配置yum源

• 然後先清除原來的元數據

yum clean all

• 然後更新yum源緩存

yum makecache fast

• 查看yum倉庫列表

yum repolist

• 安裝依賴包：

yum install -y yum-utils \
device-mapper-persistent-data \
lvm2 

• 需要container-selinux支持
  下載

wget ./ https://mirrors.huaweicloud.com/centos-altarch/7/extras/aarch64/Packages/container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm

安裝 container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm

rpm -ivh container-selinux-2.119.1-1.c57a6f9.el7.noarch.rpm

查看container-selinux被安裝情況

rpm -qa | grep container-selinux

下面開始安裝docker-ce

yum -y install docker-ce docker-ce-cli containerd.io

• 查看docker狀態

systemctl status docker

• 啓動docker

systemctl start docker

• 再查看docker狀態

systemctl status docker

• 設置docker開機自啓動

systemctl enable docker

• 查看docker版本

docker -v

配置docker加速器（注意不要出現中文和空格，可以Tab縮進），可以拉取快一些

vim /etc/docker/daemon.json

{
	"registry-mirrors":["https://bjtzu1jb.mirror.aliyuncs.com"]
}

cat /etc/docker/daemon.json

• 加載docker配置文件daemon.json

systemctl daemon-reload

• 重啓docker服務

systemctl restart docker

• 查看docker狀態

systemctl status docker

• 拉取tomcat8

docker pull tomcat:8

• 查看鏡像

docker images

創建並啓動tomcat容器

docker run -d --name tomcat8 -p 8081:8080 -v /root/software:/usr/local/tomcat/webapps tomcat:8

-d	就是在後臺運行容器
–name	指定docker名字
-p	指定端口映射，hostport:containerport
-v	指定(新建一個)本地目錄映射到容器目錄

• 查看運行的docker進程

docker ps -a

• 進入容器

docker exec -it f89 /bin/bash

這個命令是進入已運行的容器。

-i	以交互模式運行容器，通常與 -t 同時使用；
-t	爲容器重新分配一個僞輸入終端，通常與 -i 同時使用；
-d	後臺運行容器，並返回容器ID；

進入tomcat容器後

mv webapps.dist/* webapps

rm -rf webapps.dist/

ls -l webapps

linux服務器本地目錄和容器內部聯繫起來

這樣就可以直接在linux服務器本地目錄修改文件了

然後xshell遠程linux服務器，通過xftp可以實現從windows上傳文件
