    Ubuntu 12.04 Openstack Essex 安装（单节点）Swift篇

    OpenStack admin 2829浏览 0评论

    安装软件

    apt-get -y install swift swift-proxy swift-account swift-container swift-object 
xfsprogs curl python-pastedeploy

     

    分区

    我安装系统的时候，有一个专门的分区给swift使用。分区前，先umount

    umount /dev/sda6

    格式化分区

    mkfs.xfs -f -i size=1024 /dev/sda6

    创建挂载点

    mkdir /mnt/swift_backend

    修改/etc/fstab, 原来是采用uuid，注释掉，加上

    /dev/sda6 /mnt/swift_backend xfs noatime,nodiratime,nobarrier,logbufs=8 0 0

    检查修改是否正确

    mount -a

    如果fstab有错误，会进行提示。没错误，就会把目录挂载上。

    目录设置

     

    pushd /mnt/swift_backend
mkdir node1 node2 node3 node4
popd
chown swift.swift /mnt/swift_backend/*
for i in {1..4}; do sudo ln -s /mnt/swift_backend/node$i /srv/node$i; done;
mkdir -p /etc/swift/account-server 
/etc/swift/container-server 
/etc/swift/object-server 
/srv/node1/device 
/srv/node2/device 
/srv/node3/device 
/srv/node4/device
mkdir /run/swift
chown -L -R swift.swift /etc/swift /srv/node[1-4]/ /run/swift

    为了在系统启动时启动Swift服务，需要把如下两行命令写入 /etc/rc.local里，位置在“exit 0;”之前：

    sudo mkdir /run/swift
sudo chown swift.swift /run/swift

    配置rsync

    编辑 /etc/default/rsync文件

    sed -i 's/RSYNC_ENABLE=false/RSYNC_ENABLE=true/g' /etc/default/rsync

    创建 /etc/rsyncd.conf

    cat > /etc/rsyncd.conf <<EOF

    重启rsync服务

    Account Server, Container Server, Object Server

    过程比较复杂，所以就考虑用脚本来搞定

    for x in {1..4}; do

    启动相关服务

    设置目录权限

    chown -R swift.swift /etc/swift

    启动swift服务

    swift-init main start
swift-init rest start

    验证

    -k，是swift账号的密码

    swift -v -V 2.0 -A http://127.0.0.1:5000/v2.0/ -U service:swift -K $SERVICE_PASSWORD stat

    StorageURL: http://10.1.199.17:8080/v1/AUTH_a8b0b44cb5db4da39b053eabac6d3ed7 Auth Token: 3f85c92d6860444e90bf0e1bedc4b45a Account: AUTH_a8b0b44cb5db4da39b053eabac6d3ed7 Containers: 0 Objects: 0 Bytes: 0 Accept-Ranges: bytes X-Trans-Id: txea28887460ff4f1d84e9e826e5514711

    你也可以直接运行 swift stat. 这时候是直接采用 租户/用户  admin/admin 去查询swift。因为我们设置了环境变量。

    swift stat
   Account: AUTH_eb68709e74314aa59c449510a91f8d56
Containers: 0
   Objects: 0
     Bytes: 0
Accept-Ranges: bytes
X-Trans-Id: txc5a3afa7f228471698c96fd561830a3d

    Glance集成Swift

    编辑 /etc/glance/glance-api.conf

    #default_store = file
default_store = swift

#swift_store_auth_address = 127.0.0.1:35357/v2.0/
swift_store_auth_address = http://10.1.199.8:5000/v2.0/

#swift_store_user = jdoe:jdoe
swift_store_user = service:swift

#swift_store_key = a86850deb2742ec3cb41518e26aa2d89
swift_store_key = password

#swift_store_create_container_on_put = False
swift_store_create_container_on_put = True

    说明

    1. swift_store_auth_addres 不能去掉http，否则会导致认证失败
    2. swift_store_key , 我理解就是swift的密码，也就是 租户 service，用户 swift的密码。

    可以直接运行下面命令实现修改

    sed -i "/default_store/s/file/swift/; /swift_store_auth_address/s/127.0.0.1:35357/$MASTER:5000/; /swift_store_user/s/jdoe:jdoe/service:swift/; /swift_store_key/s/a86850deb2742ec3cb41518e26aa2d89/$SERVICE_PASSWORD/; /swift_store_create_container_on_put/s/False/True/" /etc/glance/glance-api.conf

    重启glance服务

    service glance-api restart && service glance-registry restart

    检测

    这个时候，image就会传到swift上。在dashboard里，也可以上传文件。并且snapshot可以上传到swift上。

    swift -V 2 -A <a href="http://%24master:5000/v2.0">http://$MASTER:5000/v2.0</a> -U service:swift -K $SERVICE_PASSWORD stat
swift -V 2 -A <a href="http://%24master:5000/v2.0">http://$MASTER:5000/v2.0</a> -U service:swift -K $SERVICE_PASSWORD list

    上面命令可以查看上传的image

    没上传镜像前

    # swift -V 2 -A http://$MASTER:5000/v2.0 -U service:swift -K $SERVICE_PASSWORD stat
   Account: AUTH_678c42aa31114faeb18add84615b4e83

   Objects: 0
     Bytes: 0
Accept-Ranges: bytes

# swift -V 2 -A http://$MASTER:5000/v2.0 -U service:swift -K $SERVICE_PASSWORD list

    上传镜像后

    # swift -V 2 -A http://$MASTER:5000/v2.0 -U service:swift -K $SERVICE_PASSWORD stat
   Account: AUTH_678c42aa31114faeb18add84615b4e83

# swift -V 2 -A http://$MASTER:5000/v2.0 -U service:swift -K $SERVICE_PASSWORD list
glance

     

    其中：-V 2  指示为keystone验证； IP为keystone节点IP；service:swift为tanent：user ；-K为password

    swift -V 2 -A <a href="http://%24master:5000/v2.0">http://$MASTER:5000/v2.0</a> -U admin:admin -K $OS_PASSWORD upload test
