使用ansible命令,部署glusterfs集羣

網上部署glusterfs集羣，都是採用登陸到主機，執行命令的方式。若是瞭解ansible，使用ansible批量管理主機，部署glusterfs集羣更方便。

 

測試環境

有4臺虛擬機，全部機器都安裝centos7.4系統。

tmaster，tslave1，tslave2做爲glusterfs服務器端節點，phn做爲glusterfs客戶端節點。

10.101.19.12 tmaster
10.101.19.13 tslave1
10.101.19.14 tslave2
10.101.17.54 phn

還有一臺ansible節點，用來管理其餘主機。（假設你已經裝好了ansible節點）

 

ansible的hosts文件

[clusterfs]
10.101.19.12
10.101.19.13
10.101.19.14
10.101.17.54

[clusterfsserver]
10.101.19.12
10.101.19.13
10.101.19.14

[clusterfsclient]
10.101.17.54

 

部署過程

1. 在ansible機器上中執行，初始化主機環境

# ping全部主機
ansible clusterfs -m ping

 

# 修改時區（可選）
ansible clusterfs -m file -a 'path=/etc/localtime src=/usr/share/zoneinfo/Asia/Shanghai state=link'
ansible clusterfs -a 'date -R'

 

# 修改hosts文件
ansible clusterfs -m lineinfile -a 'path=/etc/hosts regexp=tmaster$ line="10.101.19.12 tmaster"'
ansible clusterfs -m lineinfile -a 'path=/etc/hosts regexp=tslave1$ line="10.101.19.13 tslave1"'
ansible clusterfs -m lineinfile -a 'path=/etc/hosts regexp=tslave2$ line="10.101.19.14 tslave2"'
ansible clusterfs -m lineinfile -a 'path=/etc/hosts regexp=phn$ line="10.101.17.54 phn"'

ansible clusterfs -a "ping tmaster -c 1"
ansible clusterfs -a "ping phn -c 1"

2. 在ansible機器上中執行，配置glusterfs服務器節點

# 爲clusterfs服務器節點，安裝軟件
ansible clusterfsserver -m package -a 'name=centos-release-gluster state=present'
ansible clusterfsserver -m package -a 'name=glusterfs state=present'
ansible clusterfsserver -m package -a 'name=glusterfs-server state=present'
ansible clusterfsserver -m package -a 'name=glusterfs-fuse state=present'
ansible clusterfsserver -m package -a 'name=glusterfs-rdma state=present'

 

# 爲clusterfs服務器節點，啓動服務
ansible clusterfsserver -m service -a 'name=glusterd enabled=yes state=started'
ansible clusterfsserver -a 'systemctl status glusterd'

 

# 爲clusterfs服務器節點，建立數據目錄
ansible clusterfsserver -m file -a 'path=/opt/gluster/data state=directory'

3. 在master節點上執行，建立集羣，和添加volume等
gluster peer probe tmaster 
gluster peer probe tslave1 
gluster peer probe tslave2
gluster peer status

 

gluster volume info
gluster volume create models replica 3 tmaster:/opt/gluster/data tslave1:/opt/gluster/data tslave2:/opt/gluster/data force
gluster volume info
gluster volume start models

4. 在ansible機器上中執行，爲客戶端節點，安裝軟件等
ansible clusterfsclient -m package -a 'name=glusterfs state=present'
ansible clusterfsclient -m package -a 'name=glusterfs-fuse state=present'

 

爲客戶端節點，掛載卷
ansible clusterfsclient -m file -a 'path=/opt/gfsmount  state=directory'
ansible clusterfsclient -m mount -a 'path=/opt/gfsmount  state=mounted fstype=glusterfs src=tmaster:models'
ansible clusterfsclient -a "df -h"

5. 在10.101.17.54客戶端測試
time dd if=/dev/zero of=/opt/gfsmount/hello bs=100M count=1
