ansible常用命令的简单练习

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

（1）配置yum仓库并安装httpd服务

powershell 复制代码

[student@master ansible]$ ansible node1 -m yum_repository -a 'file=server name=aa description=aa1 baseurl=http://ansible.example.com/rhel9/BaseOS enabled=yes gpgcheck=no'
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=yes gpgcheck=no'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "repo": "bb",
    "state": "present"
}
[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"
    ]
}

（2）创建/www的目录设置其context值为httpd_sys_content_t

powershell 复制代码

[student@master ansible]$ ansible node1 -m file -a 'path=/www state=directory setype=httpd_sys_content_t'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0755",
    "owner": "root",
    "path": "/www",
    "secontext": "unconfined_u:object_r:httpd_sys_content_t:s0",
    "size": 6,
    "state": "directory",
    "uid": 0
}

（3）在/www下写入一个index.html的文件，其内容为welcome to luoqi，设置其context值为httpd_sys_content_t

powershell 复制代码

[student@master ansible]$ ansible node1 -m copy -a 'content="welcome to luoqi" dest=/www/index.html setype=httpd_sys_content_t'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "checksum": "2433ad103a9ed17b296822118d46955ba31ad8ef",
    "dest": "/www/index.html",
    "gid": 0,
    "group": "root",
    "md5sum": "fd2ab3cea037b6fdd568d5014b787c14",
    "mode": "0644",
    "owner": "root",
    "secontext": "system_u:object_r:httpd_sys_content_t:s0",
    "size": 16,
    "src": "/home/student/.ansible/tmp/ansible-tmp-1756436213.0637414-868-126882287786795/source",
    "state": "file",
    "uid": 0
}

（4）替换配置文件中的内容（http访问的目录改为/www，有两个地方需要修改）

powershell 复制代码

[student@master ansible]$ ansible node1 -m replace -a 'path=/etc/httpd/conf/httpd.conf regexp="DocumentRoot "/var/www/html"" replace="DocumentRoot "/www""'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "1 replacements made",
    "rc": 0
}
[student@master ansible]$ ansible node1 -m replace -a 'path=/etc/httpd/conf/httpd.conf regexp="<Directory "/var/www">" replace="<Directory "/www">"'
node1 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": "1 replacements made",
    "rc": 0
}

（5）设置防火墙（允许访问http服务）

powershell 复制代码

[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"
}

（6）起服务

powershell 复制代码

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

[student@master ansible]$ curl http://node1
welcome to luoqi[student@master ansible]$

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）添加一块硬盘（略）

（2）创建分区

powershell 复制代码

[student@master ansible]$ ansible node2 -m parted -a 'device=/dev/vdb number=1 part_type=primary part_start=10MiB part_end=1010MiB 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": 1034240.0,
            "flags": [],
            "fstype": "",
            "name": "",
            "num": 1,
            "size": 1024000.0,
            "unit": "kib"
        }
    ],
    "script": "unit KiB mklabel msdos mkpart primary 10MiB 1010MiB"
}

（3）格式化（文件系统），并查看UUID

powershell 复制代码

[student@master ansible]$ ansible node2 -m filesystem -a 'dev=/dev/vdb1 fstype=ext4'
node2 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true
}
[student@master ansible]$ ansible node2 -m shell -a 'blkid /dev/vdb1'
node2 | CHANGED | rc=0 >>
/dev/vdb1: UUID="ab990f13-b8d4-4215-aebb-85f5cf2f519a" TYPE="ext4" PARTUUID="88bd718e-01"

（4）创建挂载目录，并挂载

powershell 复制代码

[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
}
[student@master ansible]$ ansible node2 -m mount -a 'src=UUID=ab990f13-b8d4-4215-aebb-85f5cf2f519a 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",

    "opts": "defaults",
    "passno": "0",
    "src": "UUID=ab990f13-b8d4-4215-aebb-85f5cf2f519a"
}
[student@master ansible]$ ansible node2 -m shell -a 'df -Th'
node2 | CHANGED | rc=0 >>
Filesystem     Type      Size  Used Avail Use% Mounted on
devtmpfs       devtmpfs  4.0M     0  4.0M   0% /dev
tmpfs          tmpfs     985M     0  985M   0% /dev/shm

/dev/vdb1      ext4      966M   24K  900M   1% /testdir

3、对node3主机操作创建卷组datastorage，逻辑卷database，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）添加一块硬盘

（2）创建分区

powershell 复制代码

[student@master ansible]$ ansible node3 -m parted -a 'device=/dev/vdb number=1 part_type=primary part_start=10MiB part_end=1010MiB state=present'
node3 | 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": 1034240.0,
            "flags": [],
            "fstype": "",
            "name": "",
            "num": 1,
            "size": 1024000.0,
            "unit": "kib"
        }
    ],
    "script": "unit KiB mklabel msdos mkpart primary 10MiB 1010MiB"
}

（3）配置yum仓库并安装lvm2

powershell 复制代码

[student@master ansible]$ ansible node3 -m yum_repository -a 'file=server name=aa description=aa1 baseurl=http://ansible.example.com/rhel9/BaseOS enabled=yes gpgcheck=no'

    ]
}

（4）创建卷组

powershell 复制代码

[student@master ansible]$ ansible node3 -m lvg -a 'vg=datasorage pvs=/dev/vdb1'
node3 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true
}

（5）创建逻辑卷

powershell 复制代码

[student@master ansible]$ ansible node3 -m lvol -a 'lv=database vg=datasorage size=800M'node3 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": true,
    "msg": ""
