一、centos 6.5安裝ansible并測試

1、查看系統(tǒng)版本：

[root@ansible-server etc]# lsb_release -a

LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

Distributor ID: CentOS

Description:    CentOS release 6.5 (Final)

Release:        6.5

Codename:      Final

2、安裝ansible配置yum配置

163源

[root@ansible-server yum.repos.d]# vi CentOS-Base.repo

[163base]

name=CentOS-$releasever - Base - 163.com

baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#released updates

[163updates]

name=CentOS-$releasever - Updates - 163.com

baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#additional packages that may be useful

[163extras]

name=CentOS-$releasever - Extras - 163.com

baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

epel源

[root@ansible-server yum.repos.d]# cat epel.repo

[epel]

name=CentOS-$releasever - epel

baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/6/x86_64/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

gpgcheck=0

3、安裝ansible

[root@ansible-server ~]# yum install ansible

4、ansible安裝后測試

測試機器作為被控制端為SUSE11的虛擬機

查看配置文件

[root@ansible-server ~]# cd /etc/ansible/

[root@ansible-server ansible]# ls

ansible.cfg  hosts  roles

配置ansible hosts文件

[root@ansible-server ansible]# vi hosts

[slave]

192.168.1.210  ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass=suse

說明：

上面分別是被控制端IP地址、登陸用戶名、ssh協議端口以及登陸密碼

PING測試：

[root@ansible-server ansible]# ansible slave -m ping

paramiko: The authenticity of host '192.168.1.210' can't be established.

The ssh-rsa key fingerprint is 3eddc40386a9465452b12910a61a3c65.

Are you sure you want to continue connecting (yes/no)?

yes

192.168.1.210 | SUCCESS => {

    "changed": false,

    "ping": "pong"

第一次登陸還需要手動輸入“yes”添加信任，如果避免這一步的話也可以，需要配置ansible的配置文件ansible.cfg

hosts文件再添加一臺機器

[root@ansible-server ansible]# vi hosts

[slave]

192.168.1.210  ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass=suse

192.168.1.211  ansible_ssh_user=root ansible_ssh_port=22 ansible_ssh_pass=suse

修改配置文件，打開host_key_checking這一行的注釋

[root@ansible-server ansible]# vi ansible.cfg

#host_key_checking = False

host_key_checking = False

測試如下所示

[root@ansible-server ansible]# ansible 192.168.1.211 -m ping

192.168.1.211 | SUCCESS => {

    "changed": false,

    "ping": "pong"

第一次登陸不需要手動輸入

二、安裝tower

1、資源下載

https://www.ansible.com/license

此鏈接下載免費控制10個機器的授權，需要填寫郵箱等信息，授權文件會發(fā)到你的郵箱，安裝tower后登陸到web界面添加授權文件就可以開始你的tower之旅了

https://www.ansible.com/tower-trial

此鏈接是下載免費測試的tower安裝引導文件，叫做安裝引導文件是我自己想出的名字，因為安裝tower是由一大堆的ansible-playbook文件組合到一塊去取網絡資源安裝的

2、解壓縮tower引導文件

[root@ansible-server ~]# cd /home/ansible/

[root@ansible-server ansible]# ls

ansible-tower-setup-latest.tar.gz

[root@ansible-server ansible]# tar zxf ansible-tower-setup-latest.tar.gz

[root@ansible-server ansible]# cd ansible-tower-setup-3.0.3/

[root@ansible-server ansible-tower-setup-3.0.3]# ls

ansible.cfg  group_vars  inventory  README.md    roles

backup.yml  install.yml  licenses  restore.yml  setup.sh

3、配置安裝tower的yum源

以centos系統(tǒng)默認的yum源替代163的yum源

[root@ansible-server yum.repos.d]# vi CentOS-Base.repo

[base]

name=CentOS-$releasever - Base

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#released updates

[updates]

name=CentOS-$releasever - Updates

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#additional packages that may be useful

[extras]

name=CentOS-$releasever - Extras

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras

#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

epel源不變

4、部署tower

解壓縮軟件包

tar -zxf ansible-tower-setup-latest.tar.gz

設置主機信息

[root@ansible-server ansible]# cd ansible-tower-setup-3.0.3/

[root@ansible-server ansible-tower-setup-3.0.3]# ll

total 64

-rw-rw-r--.  1 1004 1004  203 Oct 31 21:58 ansible.cfg

-rw-rw-r--.  1 1004 1004  128 Oct 31 21:58 backup.yml

drwxrwxr-x. 18 1004 1004  4096 Oct 31 21:58 roles

-rwxrwxr-x.  1 1004 1004  9461 Oct 31 21:58 setup.sh

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i "s#password=''#password='admin'#g" inventory

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i "s#host=''#host='127.0.0.1'#g" inventory

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i "s#port=''#port='5432'#g" inventory

配置軟件源

[root@ansible-serveransible-tower-setup-3.0.3]# sed -i 's#dl.Fedoraproject.org/pub#mirrors.ustc.edu.cn#g' roles/packages_el/defaults/main.yml

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i 's/#baseurl=/baseurl=/g' roles/packages_el/files/epel-6.repo

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i 's/mirrorlist=/#mirrorlist=/g' roles/packages_el/files/epel-6.repo

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i 's#download.fedoraproject.org/pub#mirrors.ustc.edu.cn#g' roles/packages_el/files/epel-6.repo

[root@ansible-server ansible-tower-setup-3.0.3]# yum -y install centos-release-scl-rh centos-release-scl

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i 's#mirror.centos.org#centos.ustc.edu.cn#g' /etc/yum.repos.d/CentOS-SCLo-scl.repo

[root@ansible-server ansible-tower-setup-3.0.3]# sed -i 's#mirror.centos.org#centos.ustc.edu.cn#g' /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo

[root@ansible-server ansible-tower-setup-3.0.3]# yum -y install supervisor

安裝tower

為了防止出現內存過小的報錯，修改preflight的tasks文件

[root@ansible-server ansible-tower-setup-3.0.3]# vi roles/preflight/tasks/main.yml

修改下面一行

minimum_var_space: 10000000000

把參數修改到盡量小

minimum_var_space: 100000000

default目錄下也是同理

[root@ansible-server ansible-tower-setup-3.0.3]# vi roles/preflight/defaults/main.yml

修改下面一行

minimum_var_space: 10000000000

把參數修改到盡量小

minimum_var_space: 100000000

安裝tower

[root@ansible-server ansible-tower-setup-3.0.3]#./setup.sh

如果出現preflight安裝的錯誤，刪除roles/preflight/tasks/main.yml文件再嘗試

當然也可能因為網絡的原因出現timeout的錯誤，不過沒關系再次嘗試

如果網絡沒有問題的話還回出現類似于下面所示的報錯：

TASK [awx_install : Migrate the Tower database schema (may take awhile when upgrading).] ***

提示數據庫連接不上，解決辦法：

啟動postgresql

# service postgresql-9.4 initdb

# service postgresql-9.4 start

# chkconfig postgresql-9.4 on

創(chuàng)建用戶

# su - postgres

-bash-4.1$ psql

psql (8.4.20)

Type "help" for help.

postgres=# \password postgres;

Enter new password:

Enter it again:

postgres=# CREATE ROLE awx CREATEDB PASSWORD 'admin' LOGIN;

CREATE ROLE

postgres-# \q

[root@ansible-server ~]# sed -i 's#peer#md5#g' /var/lib/pgsql/data/pg_hba.conf

[root@ansible-server ~]# sed -i 's#ident#md5#g' /var/lib/pgsql/data/pg_hba.conf 

[root@ansible-server ~]# service postgresql-9.4 restart

Stopping postgresql service:                              [  OK  ]

Starting postgresql service:                              [  OK  ]

測試awx用戶連接，輸入密碼連接，并創(chuàng)建數據庫

[root@ansible-server pgsql]# psql -U awx -d postgres -h 127.0.0.1

Password for user awx:

psql (8.4.20)

Type "help" for help.

postgres=> create database awx;

CREATE DATABASE

postgres=> \q

再次執(zhí)行安裝過程

[root@ansible-server ansible-tower-setup-3.0.3]# ./setup.sh

最后出現安裝成功的提示說明tower安裝完成

三、導入licenses

安裝完成后就可以通過https://IP/#來訪問你的tower界面了，這里的IP是安裝tower的服務器IP

訪問如下圖所示：

接下來導入我們申請的license

提交后就可以進入tower的管理頁面了
