OpenStack-M版(Mitaka)搭建基于（Centos7.2）+++十、Openstack对象存储服务（swift）中

十、Openstack对象存储服务（swift）中

计算节点上（我把计算节点当存储节点用添加了sdb，sdc两块硬盘）

1.安装软件包：

yum install xfsprogs rsync  openstack-swift-account openstack-swift-container openstack-swift-object

2.使用XFS格式化/dev/sdb和/dev/sdc两块盘

mkfs.xfs /dev/sdb

mkfs.xfs /dev/sdc

[root@compute ~]# mkfs.xfs /dev/sdbmeta-data=/dev/sdb               isize=256    agcount=4, agsize=655360 blks         =                       sectsz=512   attr=2, projid32bit=1         =                       crc=0        finobt=0data     =                       bsize=4096   blocks=2621440, imaxpct=25         =                       sunit=0      swidth=0 blksnaming   =version 2              bsize=4096   ascii-ci=0 ftype=0log      =internal log           bsize=4096   blocks=2560, version=2         =                       sectsz=512   sunit=0 blks, lazy-count=1realtime =none                   extsz=4096   blocks=0, rtextents=0[root@compute ~]# mkfs.xfs /dev/sdcmeta-data=/dev/sdc               isize=256    agcount=4, agsize=655360 blks         =                       sectsz=512   attr=2, projid32bit=1         =                       crc=0        finobt=0data     =                       bsize=4096   blocks=2621440, imaxpct=25         =                       sunit=0      swidth=0 blksnaming   =version 2              bsize=4096   ascii-ci=0 ftype=0log      =internal log           bsize=4096   blocks=2560, version=2         =                       sectsz=512   sunit=0 blks, lazy-count=1realtime =none                   extsz=4096   blocks=0, rtextents=0

3.创建挂载点目录

[root@compute ~]# mkdir -p /srv/node/sdb[root@compute ~]# mkdir -p /srv/node/sdc

4.设置开机自动挂载

编辑文件/etc/fstab

添加两行：

/dev/sdb /srv/node/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 2

/dev/sdc /srv/node/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 2

vi /etc/fstab添加/dev/sdb /srv/node/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 2/dev/sdc /srv/node/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 2

5.挂载设备

[root@compute ~]# mount /srv/node/sdb[root@compute ~]# mount /srv/node/sdc

此操作无返回

验证是否挂载成功

[root@compute ~]# df -hFilesystem               Size  Used Avail Use% Mounted on/dev/mapper/centos-root   28G  1.5G   26G   6% /devtmpfs                 903M     0  903M   0% /devtmpfs                    913M     0  913M   0% /dev/shmtmpfs                    913M  8.6M  904M   1% /runtmpfs                    913M     0  913M   0% /sys/fs/cgroup/dev/sda1                497M  169M  328M  35% /boottmpfs                    183M     0  183M   0% /run/user/0/dev/sdb                  10G   33M   10G   1% /srv/node/sdb/dev/sdc                  10G   33M   10G   1% /srv/node/sdc

6.修改配置文件/etc/rsyncd.conf文件添加以下内容

vi /etc/rsyncd.confuid = swift#以哪个用户的身份来传输   gid = swift#以哪个组的身份来传输   log file = /var/log/rsyncd.log#指定rsync发送消息日志文件pid file = /var/run/rsyncd.pid#守护进程pid文件address = 192.168.100.20（存储节点管理ip我这里就是计算节点ip）账户模块[account]max connections = 2#客户端最大连接数path = /srv/node/#模块根目录，必须指定read only = False#是否只读lock file = /var/lock/account.lock#锁目录容器模块[container]max connections = 2#客户端最大连接数path = /srv/node/#模块根目录，必须指定read only = False#是否只读lock file = /var/lock/container.lock#锁目录对象模块[object]max connections = 2#客户端最大连接数path = /srv/node/#模块根目录，必须指定read only = False#是否只读lock file = /var/lock/object.lock#锁目录

7.启动 rsyncd 服务和配置它随系统启动

systemctl enable rsyncd.service

systemctl start rsyncd.service

[root@compute ~]# systemctl enable rsyncd.serviceCreated symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.[root@compute ~]# systemctl start rsyncd.service

8.从对象存储源仓库中获取accounting, container以及object服务配置文件

没有网就打开网址自己复制进文件，删除里面以前的内容

curl -o /etc/swift/account-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/account-server.conf-sample

curl -o /etc/swift/container-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample

curl -o /etc/swift/object-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample

[root@compute ~]# curl -o /etc/swift/account-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/account-server.conf-sample  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100  9777  100  9777    0     0   5931      0  0:00:01  0:00:01 --:--:--  5950[root@compute ~]# curl -o /etc/swift/container-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100 11028  100 11028    0     0   7342      0  0:00:01  0:00:01 --:--:--  7347[root@compute ~]# curl -o /etc/swift/object-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100 17947  100 17947    0     0  11891      0  0:00:01  0:00:01 --:--:-- 11901

9.修改配置文件/etc/swift/account-server.conf （账户服务）

vi /etc/swift/account-server.conf bind_ip = 192.168.100.20#存储节点管理ip我这里就是计算节点ip）bind_port = 6002#绑定端口user = swift#用户swift_dir = /etc/swift#配置文件目录devices = /srv/node#挂载目录mount_check = True#挂载检查启用合适的模块（从对象仓库获取后就有的其实不用管，不放心自己去看）[pipeline:main]pipeline = healthcheck recon account-server配置recon （meters）缓存目录[filter:recon]use = egg:swift#reconrecon_cache_path = /var/cache/swift

10.修改配置文件/etc/swift/container-server.conf （容器服务）

vi /etc/swift/container-server.confbind_ip = 192.168.100.20#存储节点管理ip我这里就是计算节点ip）bind_port = 6001#绑定端口user = swift#用户swift_dir = /etc/swift#配置文件目录devices = /srv/node#挂载目录mount_check = True#挂载检查启用合适的模块（从对象仓库获取后就有的其实不用管，不放心自己去看）[pipeline:main]pipeline = healthcheck recon container-server配置recon （meters）缓存目录[filter:recon]use = egg:swift#reconrecon_cache_path = /var/cache/swift

11.修改配置文件/etc/swift/object-server.conf（对象服务）

注意：[filter:recon]下有两个路径地址，并不和上面一样只有一个

vi /etc/swift/object-server.confbind_ip = 192.168.100.20#存储节点管理ip我这里就是计算节点ip）bind_port = 6000#绑定端口user = swift#用户swift_dir = /etc/swift#配置文件目录devices = /srv/node#挂载目录mount_check = True#挂载检查启用合适的模块（从对象仓库获取后就有的其实不用管，不放心自己去看）[pipeline:main]pipeline = healthcheck recon object-server配置recon （meters）缓存目录[filter:recon]use = egg:swift#reconrecon_cache_path = /var/cache/swiftrecon_lock_path = /var/lock

12.添加合适权限给目录挂载点

chown -R swift:swift /srv/node

[root@compute ~]# chown -R swift:swift /srv/node

13.创建 recon 目录授予它合适的所有权

mkdir -p /var/cache/swift

chown -R root:swift /var/cache/swift

chmod -R 775 /var/cache/swift

[root@compute ~]# mkdir -p /var/cache/swift[root@compute ~]# chown -R root:swift /var/cache/swift[root@compute ~]# chmod -R 775 /var/cache/swift
