【ansible】使用ansible安装nginx

1、主机准备

ServerIP：10.10.10.102

ClientIP：  10.10.10.103,10.10.10.104

 

2、安装ansible

yum -y install ansible

 

3、配置免密登陆

1.在Server上制做公钥和私钥

[root@localhost roles]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:fsarmF7FOVq6/s2ka/VjhEIjbnEcPoQvobEqL1dV63g root@localhost.localdomain The key's randomart image is:
+---[RSA 2048]----+
|         .       |
|      . o +      |
|       + B o     |
|      o =.X.     |
|     . oSO*o .   |
|  . . ..+*E.o .  |
|   o . .=.+o.o   |
|  . o  + +.*  +  |
|   o .+.++=.o. . |
+----[SHA256]-----+ [root@localhost roles]# 

 

2.将Server上的公钥复制到Client上

ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@10.10.10.103

ssh-copy-id -i ~/.ssh/id_rsa.pub -p 22 root@10.10.10.104

#写入成功后会在10.10.10.103目录~/.ssh/下生成authorized_keys #验证免密登陆是否成功，回车后能登陆成功，说明设置成功 ssh root@10.10.10.103

 

4、编写ansible相关配置文件

1.ansible的目录结构以下

├── ansible.cfg
├── hosts
├── install_nginx.yml
└── roles
     └── install_nginx
          ├── files
          │   ├── install_nginx.sh
          │   └── nginx-1.14.0.tar.gz
          ├── tasks
          │   └── main.yml
          ├── templates
          └── vars
              └── main.yml

 2.相关配置文件内容以下：

 

/etc/ansible/hosts文件：

[Client] 10.10.10.103
10.10.10.104

 

/etc/ansible/install_nginx.yml

[root@CentOS7 ansible]# more install_nginx.yml ---
- hosts: Client roles: - install_nginx

 

/etc/ansible/roles/install_nginx/files/install_nginx.sh

[root@CentOS7 files]# more install_nginx.sh #!/bin/bash cd /usr/local/nginx-1.14.0 ./configure --prefix=/usr/local/nginx make && make install /usr/local/nginx/sbin/nginx

 

/etc/ansible/roles/install_nginx/tasks/main.yml

[root@CentOS7 tasks]# more main.yml ---
  - name: Install Software yum: name={{ item }} state=latest with_items: - gcc -  gcc-c++ 
      -  zlib-devel -  pcre-devel - openssl -  openssl-devel - name: Copy nginx.tar.gz copy: src=nginx-{{ nginx_version }}.tar.gz dest={{ nginx_dir }}/nginx-{{ nginx_version }}.tar.gz owner=root group=root - name: Copy install_nginx.sh copy: src=install_nginx.sh dest=/tmp/install_nginx.sh - name: uncompress nginx.tar.gz shell: tar -xf {{ nginx_dir }}/nginx-{{ nginx_version }}.tar.gz -C {{ nginx_dir }}/
  - name: install nginx shell: /bin/bash /tmp/install_nginx.sh

 

/etc/ansible/roles/install_nginx/vars/main.yml

[root@CentOS7 vars]# more main.yml nginx_dir: /usr/local nginx_version: 1.14.0

 

5、使用ansible安装nginx并启动

[root@CentOS7 ansible]# cd /etc/ansible

[root@CentOS7 ansible]# ansible-playbook install_nginx.yml PLAY [Client] ****************************************************************************************************************************************************** TASK [Gathering Facts] ********************************************************************************************************************************************* ok: [10.10.10.103] ok: [10.10.10.104] TASK [install_nginx : Install Software] **************************************************************************************************************************** ok: [10.10.10.103] => (item=[u'gcc', u'gcc-c++', u'zlib-devel', u'pcre-devel', u'openssl', u'openssl-devel']) ok: [10.10.10.104] => (item=[u'gcc', u'gcc-c++', u'zlib-devel', u'pcre-devel', u'openssl', u'openssl-devel']) TASK [install_nginx : Copy nginx.tar.gz] *************************************************************************************************************************** changed: [10.10.10.103] changed: [10.10.10.104] TASK [install_nginx : Copy install_nginx.sh] *********************************************************************************************************************** changed: [10.10.10.103] changed: [10.10.10.104] TASK [install_nginx : uncompress nginx.tar.gz] ********************************************************************************************************************* [WARNING]: Consider using unarchive module rather than running tar changed: [10.10.10.103] changed: [10.10.10.104] TASK [install_nginx : install nginx] ******************************************************************************************************************************* changed: [10.10.10.103] changed: [10.10.10.104] PLAY RECAP *********************************************************************************************************************************************************
10.10.10.103               : ok=6    changed=4    unreachable=0    failed=0   
10.10.10.104               : ok=6    changed=4    unreachable=0    failed=0

 

6、验证

在安装完成后，能够到Client验证nginx是否安装完成！

以下是在10.10.10.104上的验证结果：

[root@CentOS7 local]# ps -ef|grep nginx root 35688     1  0 04:24 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx nobody 35689 35688  0 04:24 ?        00:00:00 nginx: worker process root 43485 19737  0 18:34 pts/2    00:00:00 grep --color=auto nginx [root@CentOS7 local]#
