测试题ansible临时命令模块

使用ansible临时命令完成以下操作
1、对node1主机操作，安装httpd服务，网页存放在/www目录中，能够通过curl http://node1访问到网页内容为welcome to luoqi

步骤

1.配置yum仓库

[student@master ansible]$ ansible node1 -m yum_repository -a 'file=server name=aa description=aa1 baseurl=http://ansible.example.com/rhel9/BaseOS enabled=1 gpgcheck=0'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "repo": "aa",
    "state": "present"
}
[student@master ansible]$ ansible node1 -m yum_repository -a 'file=server name=bb description=bb1 baseurl=http://ansible.example.com/rhel9/AppStream enabled=1 gpgcheck=0'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "repo": "bb",
    "state": "present"
}

2.安装httpd

[student@master ansible]$ ansible node1 -m yum -a 'name=httpd state=present'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "",
    "rc": 0,
    "results": [
        "Installed: redhat-logos-httpd-90.4-1.el9.noarch",
        "Installed: mailcap-2.1.49-5.el9.noarch",
        "Installed: httpd-2.4.53-7.el9.x86_64",
        "Installed: apr-1.7.0-11.el9.x86_64",
        "Installed: mod_http2-1.15.19-2.el9.x86_64",
        "Installed: apr-util-1.6.1-20.el9.x86_64",
        "Installed: apr-util-bdb-1.6.1-20.el9.x86_64",
        "Installed: httpd-core-2.4.53-7.el9.x86_64",
        "Installed: httpd-filesystem-2.4.53-7.el9.noarch",
        "Installed: httpd-tools-2.4.53-7.el9.x86_64",
        "Installed: apr-util-openssl-1.6.1-20.el9.x86_64",
        "Installed: mod_lua-2.4.53-7.el9.x86_64"
    ]
}

3.添加httpd到防火墙

[student@master ansible]$ ansible node1 -m firewalld -a 'service=http permanent=yes state=enabled immediate=yes'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "Permanent and Non-Permanent(immediate) operation, Changed service http to enabled"
}

4.将httpd的配置文件/var/www/html替换为/www

[student@master ansible]$ ansible node1 -m replace -a 'path=/etc/httpd/conf/httpd.conf regexp=/var/www/html replace=/www'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "2 replacements made",
    "rc": 0
}
[student@master ansible]$ ansible node1 -m replace -a 'path=/etc/httpd/conf/httpd.conf regexp=/var/www replace=/www'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "2 replacements made",
    "rc": 0
}

5.创建/www目录在index.html写welcome to luoqi

[student@master ansible]$ ansible node1 -m copy -a 'content="welcome to luoqi\n" dest=/www/index.html'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "checksum": "080c07240d102be98b4ba40c353c6be1ed069804",
    "dest": "/www/index.html",
    "gid": 0,
    "group": "root",
    "md5sum": "fe7dc696d70cc7434ef50c0b2073c16d",
    "mode": "0644",
    "owner": "root",
    "secontext": "unconfined_u:object_r:default_t:s0",
    "size": 17,
    "src": "/home/student/.ansible/tmp/ansible-tmp-1756347674.2490287-1145-199591374172433/source",
    "state": "file",
    "uid": 0
}

6.修改context值

[student@master ansible]$ ansible node1 -m sefcontext -a 'target="/www(/.*)?" setype=httpd_sys_content_t state=present'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "ftype": "a",
    "serange": "s0",
    "setype": "httpd_sys_content_t",
    "seuser": "system_u",
    "state": "present",
    "target": "/www(/.*)?"
}
[student@master ansible]$ ansible node1 -m shell -a 'restorecon -Rv /www'
node1 | CHANGED | rc=0 >>
Relabeled /www from unconfined_u:object_r:default_t:s0 to unconfined_u:object_r:httpd_sys_content_t:s0
Relabeled /www/index.html from unconfined_u:object_r:default_t:s0 to unconfined_u:object_r:httpd_sys_content_t:s0

7.重启HTTPd服务

[student@master ansible]$ ansible node1 -m service -a 'name=httpd state=restarted enabled=yes'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"

8.访问curl http://node1

[root@node1 ~]# curl  http://node1
welcome to luoqi

2、对node2主机操作，创建一个1000MiB的分区，格式化成ext4的文件系统，并挂载到/testdir目录下。
使用ansible node2 -m shell -a 'df -Th’验证

1.新建分区

[student@master ansible]$ ansible node2 -m parted -a 'device=/dev/vdb number=1 part_type=primary part_start=10MiB part_end=1100MiB state=present '
node2 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "disk": {
        "dev": "/dev/vdb",
        "logical_block": 512,
        "model": "Virtio Block Device",
        "physical_block": 512,
        "size": 20971520.0,
        "table": "msdos",
        "unit": "kib"
    },
    "partitions": [
        {
            "begin": 10240.0,
            "end": 1126400.0,
            "flags": [],
            "fstype": "",
            "name": "",
            "num": 1,
            "size": 1116160.0,
            "unit": "kib"
        }
    ],
    "script": "unit KiB mklabel msdos mkpart primary 10MiB 1100MiB"
}

2.格式化

[student@master ansible]$ ansible node2 -m filesystem -a 'fstype=ext4 dev=/dev/vdb1'
node2 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true
}

3.创建目录

[student@master ansible]$ ansible node2 -m file -a 'path=/testdir state=directory'
node2 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0755",
    "owner": "root",
    "path": "/testdir",
    "secontext": "unconfined_u:object_r:default_t:s0",
    "size": 6,
    "state": "directory",
    "uid": 0
}

4.查看uuid与挂载

[student@master ansible]$ ansible node2 -m shell -a 'blkid '
node2 | CHANGED | rc=0 >>
/dev/vdb1: UUID="b0e99531-86aa-40cc-9e9a-6cb1a5fae2ab" TYPE="ext4" PARTUUID="9912f982-01"

[student@master ansible]$ ansible node2 -m mount -a 'src="UUID=b0e99531-86aa-40cc-9e9a-6cb1a5fae2ab" path=/testdir fstype=ext4 state=mounted'
node2 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "backup_file": "",
    "boot": "yes",
    "changed": true,
    "dump": "0",
    "fstab": "/etc/fstab",
    "fstype": "ext4",
    "name": "/testdir",
    "opts": "defaults",
    "passno": "0",
    "src": "UUID=b0e99531-86aa-40cc-9e9a-6cb1a5fae2ab"
}

5.查看挂载

[student@master ansible]$ ansible node2 -m shell -a 'df -h'
4^Hnode2 | CHANGED | rc=0 >>
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        4.0M     0  4.0M   0% /dev

/dev/vdb1       1.1G   24K  968M   1% /testdir

3、对node3主机操作创建卷组vg0，逻辑卷lv0，大小为800M，格式化为xfs的文件系统，并挂载到/lv目录下
使用ansible node3 -m shell -a 'df -Th’验证

1.在node3配置yum仓库

[student@master ansible]$ ansible node3 -m yum_repository -a 'file=server name=aa description=aa1 baseurl=http://ansible.example.com/rhel9/BaseOS enabled=1 gpgcheck=0'
node3 | CHANGED => {
    "ansible_facts": {
