使用ansible 写出vsftpd

使用ansible编写vsftpd的配置文件和服务的安装和启动脚本：

1. 编写vsftpd的配置文件

# /etc/vsftpd.conf

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
chroot_local_user=YES
chroot_list_file=/etc/vsftpd.chroot_list
listen=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

2. 编写安装和启动脚本

---
- hosts: ftp_servers
  become: true
  vars:
    vsftpd_conf_path: /etc/vsftpd.conf
    vsftpd_service_name: vsftpd
  tasks:
    - name: Install vsftpd package
      apt:
        name: vsftpd
        state: present

    - name: Create vsftpd user
      user:
        name: ftpuser
        shell: /sbin/nologin
        system: yes

    - name: Create vsftpd directory
      file:
        path: /home/ftpuser
        state: directory
        owner: ftpuser
        group: ftpuser
        mode: 0755

    - name: Set vsftpd password
      shell: "echo 'ftpuser:password' | chpasswd"

    - name: Create vsftpd chroot list file
      copy:
        dest: /etc/vsftpd.chroot_list
        content: |
          ftpuser

    - name: Copy vsftpd configuration file
      copy:
        src: files/vsftpd.conf
        dest: "{{ vsftpd_conf_path }}"
        owner: root
        group: root
        mode: 0644

    - name: Restart vsftpd service
      service:
        name: "{{ vsftpd_service_name }}"
        state: restarted

注意，上面的脚本中的`ftp_servers`是指定的主机组名称，需要在Ansible的inventory文件中定义。另外，需要将vsftpd的配置文件`vsftpd.conf`和密码文件`vsftpd.chroot_list`放在指定的`files`目录中。
