使用Ansible搭建LNMP
阿新 • • 發佈：2018-12-01
安裝Ansible
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!"，需要安裝支援包
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
└── vars
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
[
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

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
搭建mysql，roles的模板

mysl的安裝指令碼（需要注意的是這裡使用的是二進位制壓縮包，簡單的指令碼，不嚴謹，可以執行成功）
#!/bin/bash

web1 : ok=5 changed=1 unreachable=0 failed=0
如果報錯ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
是說明找不到sockt啟動檔案，第一個辦法是修改配置檔案的路徑
[[email protected] ~]# vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
第二個辦法是直接做個軟連線就可以
ln -s /var/lib/mysql/* /tmp/
