用ansible劇本搭建lnmp

首先在主伺服器上搭建ansible直接用雲yum裝就可以，
yum -y install ansible
如果copy報錯一下的語句 "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
需要在被分發的伺服器上安裝支援包 [[email protected] ~]# mount /dev/sr0 /media/cdrom/ mount: block device /dev/sr0 is write-protected, mounting read-only [[email protected] ~]# yum -y install libselinux-python
然後建立roles的標準化模組相應的目錄
[[email protected] myroles]# tree /myroles/ /myroles/ ├── nginx.yaml #nginx模組入口配置檔案 └── roles └── nginx #nginx原型模組目錄 ├── files ├── handlers ├── tasks │ └── main.yaml #nginx模組的tasks任務配置檔案 ├── templates └── vars7 directories, 2 files
Nginx的劇本書寫，在myroles裡，跟roles同級
---
- hosts: all
gather_facts: True
roles:
- nginx
然後在Nginx目錄下files目錄裡放置安裝包和，安裝指令碼檔案
nginx的搭建指令碼
#!/bin/bash mkdir -p /media/cdrom umount /dev/sr0 &>/dev/null mount /dev/sr0 /media/cdrom &>/dev/null dir=/etc/yum.repos.d [-d $dir ] || mkdir -p $dir cd $dir mv * /tmp/ cat >/etc/yum.repos.d/local.repo << KOF [local] name=localrepo baseurl=file:///media/cdrom/ KOF yum -y clean all &>/dev/null [ $? -eq 0 ] || echo "clean erro" yum makecache &>/dev/null || echo "erro cache" which "wget" [ $? -eq 0 ] || /usr/bin/yum -y install wget &>/dev/null /usr/bin/wget http://mirrors.aliyun.com/repo/epel-6.repo [ $? -eq 0 ] || (/bin/echo "yun源出錯" && exit) /usr/bin/yum -y clean all &>/dev/null /usr/bin/yum makecache &>/dev/null [ $? -eq 0 ] || (/bin/echo "yun快取錯誤" && exit) /usr/bin/yum -y install pcre-deved openssl-devel &>/dev/null [ $? -eq 0 ] || /bin/echo "pcre error" useradd -M -s /sbin/nologin nginx &>dev/null cd ~ tar xf nginx-1.10.2.tar.gz -C /usr/src/ cd /usr/src/nginx-1.10.2/ ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx-1.10.2/ --with-http_stub_status_module --with-http_ssl_module && make && make install &>/dev/null
在tasks裡建立個main.yaml主要任務劇本
- name: t1 copy: src=nginx-1.10.2.tar.gz dest=/root/ register: ttt - debug: var=ttt - name: t2 script: nginx.sh register: rrr - debug: var=rrr
回到mysoles裡執行nginx.yaml劇本
[[email protected] myroles]# ansible-playbook nginx.yaml PLAY [all] ************************************************************************************************* TASK [Gathering Facts] ************************************************************************************* ok: [web1] ok: [web2] TASK [nginx : t1] ****************************************************************************************** ok: [web2] ok: [web1] TASK [nginx : debug] *************************************************************************************** ok: [web1] => { "ttt": { "changed": false, "checksum": "1bafb1557b8d5f992714c0dcbde77036bde98547", "dest": "/root/nginx-1.10.2.tar.gz", "diff": { "after": { "path": "/root/nginx-1.10.2.tar.gz" }, "before": { "path": "/root/nginx-1.10.2.tar.gz" } }, "failed": false, "gid": 0, "group": "root", "mode": "0644", "owner": "root", "path": "/root/nginx-1.10.2.tar.gz", "secontext": "unconfined_u:object_r:admin_home_t:s0", "size": 910812, "state": "file", "uid": 0 } } ok: [web2] => { "ttt": { "changed": false, "checksum": "1bafb1557b8d5f992714c0dcbde77036bde98547", "dest": "/root/nginx-1.10.2.tar.gz", "diff": { "after": { "path": "/root/nginx-1.10.2.tar.gz" }, "before": { "path": "/root/nginx-1.10.2.tar.gz" } }, "failed": false, "gid": 0, "group": "root", "mode": "0644", "owner": "root", "path": "/root/nginx-1.10.2.tar.gz", "secontext": "unconfined_u:object_r:admin_home_t:s0", "size": 910812, "state": "file", "uid": 0 } } TASK [nginx : t2] ****************************************************************************************** changed: [web2] changed: [web1] TASK [nginx : debug] *************************************************************************************** ok: [web1] => { "rrr": { "changed": true, "failed": false, "rc": 0, "stderr": "Shared connection to 192.168.200.131 closed.\r\n", "stderr_lines": [ "Shared connection to 192.168.200.131 closed." ], "stdout": "/usr/bin/wget\r\n--2018-11-12 19:02:03-- http://mirrors.aliyun.com/repo/epel-6.repo\r\nResolving mirrors.aliyun.com... failed: Name or service not known.\r\nwget: unable to resolve host address “mirrors.aliyun.com”\r\nyun源出錯\r\n", "stdout_lines": [ "/usr/bin/wget", "--2018-11-12 19:02:03-- http://mirrors.aliyun.com/repo/epel-6.repo", "Resolving mirrors.aliyun.com... failed: Name or service not known.", "wget: unable to resolve host address “mirrors.aliyun.com”", "yun源出錯" ] } } ok: [web2] => { "rrr": { "changed": true, "failed": false, "rc": 0, "stderr": "Shared connection to 192.168.200.133 closed.\r\n", "stderr_lines": [ "Shared connection to 192.168.200.133 closed." ], "stdout": "/usr/bin/wget\r\n--2018-11-12 16:03:20-- http://mirrors.aliyun.com/repo/epel-6.repo\r\nResolving mirrors.aliyun.com... 122.72.3.220, 122.72.3.219, 122.72.3.221, ...\r\nConnecting to mirrors.aliyun.com|122.72.3.220|:80... connected.\r\nHTTP request sent, awaiting response... 200 OK\r\nLength: 664 [application/octet-stream]\r\nSaving to: “epel-6.repo”\r\n\r\n\r 0% [ ] 0 --.-K/s \r100%[======================================>] 664 --.-K/s in 0s \r\n\r\n2018-11-12 16:03:21 (62.4 MB/s) - “epel-6.repo” saved [664/664]\r\n\r\n", "stdout_lines": [ "/usr/bin/wget", "--2018-11-12 16:03:20-- http://mirrors.aliyun.com/repo/epel-6.repo", "Resolving mirrors.aliyun.com... 122.72.3.220, 122.72.3.219, 122.72.3.221, ...", "Connecting to mirrors.aliyun.com|122.72.3.220|:80... connected.", "HTTP request sent, awaiting response... 200 OK", "Length: 664 [application/octet-stream]", "Saving to: “epel-6.repo”", "", "", " 0% [ ] 0 --.-K/s ", "100%[======================================>] 664 --.-K/s in 0s ", "", "2018-11-12 16:03:21 (62.4 MB/s) - “epel-6.repo” saved [664/664]", "" ] } } PLAY RECAP ************************************************************************************************* web1 : ok=5 changed=1 unreachable=0 failed=0 web2 : ok=5 changed=1 unreachable=0 failed=0
這樣Nginx服務就先簡單的搭建成功，需要主要目前沒有任何的配置檔案和啟動服務
接下來我搭建mysql
