Docker
1.拉取一个镜像 [root@localhost ~]# docker pull 10.30.5.120/docker/centos Using default tag: latest latest: Pulling from docker/centos Digest: sha256:dc29e2bcceac52af0f01300402f5e756cc8c44a310867f6b94f5f7271d4f3fec Status: Image is up to date for 10.30.5.120/docker/centos:latest 10.30.5.120/docker/centos:latest 2.创建一个容器（再前台运行的容器） [root@localhost ~]# docker run --name centos1 --rm -it 10.30.5.120/docker/centos /bin/bash [root@682712f2a2b8 /]# ifconfig bash: ifconfig: command not found [root@682712f2a2b8 /]# yum -y install net-tools //yum安装网络配置模块 [root@682712f2a2b8 /]# ifconfig //使用的时候可以查看ip地址 eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.17.0.3 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:ac:11:00:03 txqueuelen 0 (Ethernet) RX packets 4846 bytes 11686752 (11.1 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3734 bytes 205329 (200.5 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 loop txqueuelen 1000 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 3.重新开启一个端口，提交为新的镜像 [root@localhost ~]# docker commit centos1 centos:net //提交为新的镜像 sha256:7f169f2499a9e3faa8dc0077d8f02e5bcc95f888354ed1dc200083e6c8eb1246 [root@localhost ~]# docker images //查看是否有新的镜像 REPOSITORY TAG IMAGE ID CREATED SIZE centos net 7f169f2499a9 4 seconds ago 289MB 10.30.5.120/docker/mysql 5.6 57640f2e70a1 13 months ago 217MB 10.30.5.120/docker/centos latest 75835a67d134 13 months ago 200MB
[root@localhost ~]# mkdir tomcat [root@localhost ~]# cd tomcat/ [root@localhost tomcat]# vim Dockerfile FROM 10.30.5.120/docker/java ADD apache-tomcat-8.5.35.tar.gz /opt VOLUME /opt/apache-tomcat-8.5.35/webapps CMD ["/opt/apache-tomcat-8.5.35/bin/catalina.sh","run"] [root@localhost tomcat]# docker build -t tomcat:1.1 ./ Sending build context to Docker daemon 9.646MB Step 1/4 : FROM 10.30.5.120/docker/java ---> d23bdf5b1b1b Step 2/4 : ADD apache-tomcat-8.5.35.tar.gz /opt ---> Using cache ---> a16a39d65441 Step 3/4 : VOLUME /opt/apache-tomcat-8.5.35/webapps ---> Using cache ---> d08937b5756b Step 4/4 : CMD ["/opt/apache-tomcat-8.5.35/bin/catalina.sh","run"] ---> Running in b9de9f9bce00 Removing intermediate container b9de9f9bce00 ---> e957e53f7e1d Successfully built e957e53f7e1d Successfully tagged tomcat:1.1 [root@localhost tomcat]# docker run --name tomcat -d -p 8080:8080 tomcat:1.1 //基于tomcat镜像创建了一个容器 0939d93d0952c9ae522fb0d93179050be7a2dbb59c7534c1ee5ec329b62f26dc

访问页面192.168.18.140:8080/solo 这是是错误的页面
修改以下内容
重启容器
出现以下页面就是成功上线solo博客
4.docker创建一个lnmp镜像，创建容器+上线wordpress
搭建一个lnmp的镜像并并创建一个容器
[root@localhost ~]# mkdir lnmp [root@localhost ~]# cd lnmp [root@localhost lnmp]# vim Dockerfile FROM 10.30.5.120/docker/centos ADD nginx-1.16.1.tar.gz /root/ RUN curl -s http://10.30.5.70:8000/repo.sh | /bin/bash && yum -y install make gcc gcc-c++ pcre-devel zlib-devel php php-mysql php-gd php-fpm \ && cd /root/nginx-1.16.1 && ./configure && make && make install \ && yum -y install epel-release && yum -y install supervisor COPY lnmp.ini /etc/supervisord.d/ COPY nginx.conf /usr/local/nginx/conf/nginx.conf CMD ["supervisord","-n"] [root@localhost lnmp]# vim lnmp.ini ################################################## [program:nginx] command=/usr/local/nginx/sbin/nginx -g "daemon off;" [program:php-fpm] command=/usr/sbin/php-fpm -F ################################################## 创建一个容器 [root@localhost ~] docker run --name lnmp -d -p 80:80 -v /opt/html1:/usr/local/nginx/html lnmp:1.1 [root@localhost ~]# cd /opt/html1 //在此路径下传入wordpress的安装包 [root@localhost html1]# unzip wordpress-4.9.4-zh_CN.zip //解压 [root@localhost html1]# chmod -R 777 ./ //给予权限
拉取数据库的镜像myslq:5.6
[root@localhost html1]# docker pull 10.30.5.120/docker/mysql:5.6 5.6: Pulling from docker/mysql e64f6e679e1a: Pull complete b0e0af0b3f07: Pull complete 4525fe57d487: Pull complete d3565df0a804: Pull complete Digest: sha256:0ba03586c705ca8f79030586a579001c4fab3d6fa8c388b6c1c37c695645b78e Status: Downloaded newer image for 10.30.5.120/docker/mysql:5.6 10.30.5.120/docker/mysql:5.6 创建容器 [root@localhost html1]# docker run --name mysql-server -d -p 3306:3306 \ > -e MYSQL_ROOT_PASSWORD=123 \ > -e MYSQL_USER=tom \ > -e MYSQL_PASSWORD=123 \ > -e MYSQL_DATABASE=wordpress 10.30.5.120/docker/mysql:5.6
可以访问就是成功
[root@localhost ~]# yum -y install docker-ce vim lrzsz bash-completion [root@localhost ~]# systemctl stop firewalld [root@localhost ~]# setenforce 0 [root@localhost ~]# systemctl start docker [root@localhost ~]# cd /etc/docker/ [root@localhost docker]# rz //传入加速脚本 [root@localhost docker]#systemctl restart docker [root@localhost docker]# cd /usr/local/sbin/ [root@localhost sbin]# rz //传入docker-compose [root@localhost sbin]# chmod +x docker-compose [root@localhost sbin]# cd /root [root@localhost ~]# mkdir harbor [root@localhost ~]# cd harbor/ //用xftp传入harbor [root@localhost harbor]# tar -zxf harbor-offline-installer-v1.8.1.tgz [root@localhost harbor]# mv harbor /usr/local/ [root@localhost harbor]# cd /usr/local/harbor/
在本地拉取centos镜像并在镜像内安装网络工具，并制作新的镜像，上传至harbor
