linux7启动docker,apache – 在docker CentOS 7容器内启动服务

最好的方法是在你安装httpd的地方制作你自己的centos7图像

FROM centos:7

RUN yum -y install httpd; yum clean all; systemctl enable httpd.service

EXPOSE 80

使用docker build -t my-centos构建您的映像：7.

没有SYS_ADMIN,Systemd无法运行.这就是我设置以下变量的原因.

$docker run -it -p 80:80 -e "container=docker" --privileged=true -d --security-opt seccomp:unconfined --cap-add=SYS_ADMIN -v /sys/fs/cgroup:/sys/fs/cgroup:ro my-centos:7 bash -c "/usr/sbin/init"

验证容器正在运行：

$docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

967581bdf31a my-centos:7 "bash -c /usr/sbin/in" 1 seconds ago Up 1 seconds 0.0.0.0:80->80/tcp gigantic_stallman

Verifiy httpd已启动

$docker exec -it gigantic_stallman /bin/bash -c "systemctl status httpd"
