openstack swift All In One安装

操作系统：Ubuntu 14.04.3 LTS

1. 安装依赖

sudo apt-get update
sudo apt-get install curl gcc memcached rsync sqlite3 xfsprogs \
                     git-core libffi-dev python-setuptools \
                     liberasurecode-dev
sudo apt-get install python-coverage python-dev python-nose \
                     python-xattr python-eventlet \
                     python-greenlet python-pastedeploy \
                     python-netifaces python-pip python-dnspython \
                     python-mock

2. 为存储创建分区
   使用loopback设备作为存储

sudo mkdir /srv
sudo truncate -s 1GB /srv/swift-disk
sudo mkfs.xfs /srv/swift-disk

编辑分区表/etc/fstab，添加如下一行

/srv/swift-disk /mnt/sdb1 xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0

3. 创建挂在点和独立的连接

sudo mkdir /mnt/sdb1
sudo mount /mnt/sdb1
sudo mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4
sudo chown ${USER}:${USER} /mnt/sdb1/*
for x in {1..4}; do sudo ln -s /mnt/sdb1/$x /srv/$x; done
sudo mkdir -p /srv/1/node/sdb1 /srv/1/node/sdb5 \
              /srv/2/node/sdb2 /srv/2/node/sdb6 \
              /srv/3/node/sdb3 /srv/3/node/sdb7 \
              /srv/4/node/sdb4 /srv/4/node/sdb8 \
              /var/run/swift
sudo chown -R ${USER}:${USER} /var/run/swift
# **Make sure to include the trailing slash after /srv/$x/**
for x in {1..4}; do sudo chown -R ${USER}:${USER} /srv/$x/; done

4. 添加一下几行到/etc/rc.local中去

mkdir -p /var/cache/swift /var/cache/swift2 /var/cache/swift3 /var/cache/swift4
chown : /var/cache/swift*
mkdir -p /var/run/swift
chown : /var/run/swift

5. 获取代码

   1. 下载python-swiftclient 代码

   cd $HOME; git clone https://github.com/openstack/python-swiftclient.git
   

   2. 编译并安装python-swiftclient

   cd $HOME/python-swiftclient; sudo python setup.py develop; cd -
   

   3. 下载swift的代码

   git clone https://github.com/openstack/swift.git
   

   4. 编译并安装swift

   cd $HOME/swift; sudo pip install -r requirements.txt; sudo python setup.py develop; cd -
   

   4. 安装swift测试相关的依赖

   cd $HOME/swift; sudo pip install -r test-requirements.txt
   

6. 安装rsync

   1. 创建/etc/rsyncd.conf

   sudo cp $HOME/swift/doc/saio/rsyncd.conf /etc/
   sudo sed -i "s//${USER}/" /etc/rsyncd.conf
   

   2. 修改/etc/default/rsync中的下面一行

   RSYNC_ENABLE=true
   

   3. 在系统的SELinux是Enforcing模式下执行下面两个命令中的一个

   sudo setenforce Permissive
   

   仅仅允许rsync的full权限

   sudo setsebool -P rsync_full_access 1
   

   4. 启动rsync

   sudo service rsync restart
   

   5. 验证rsync是不是接受了所有的连接

   rsync rsync://pub@localhost/
   

   执行上述命令，应该会看到

   account6012
   account6022
   account6032
   account6042
   container6011
   container6021
   container6031
   container6041
   object6010
   object6020
   object6030
   object6040
   

7. 启动memcached

sudo service memcached start
sudo chkconfig memcached on

8.（可选）为独立的日志，启动rsyslog
a. 安装swift rsyslogd的配置
shell sudo cp $HOME/swift/doc/saio/rsyslog.d/10-swift.conf /etc/rsyslog.d/
b. 编辑/etc/rsyslog.conf中的下述配置

```shell
$PrivDropToGroup adm
```

c. 如果使用的是hourly logs,则执行下面的

```shell
sudo mkdir -p /var/log/swift/hourly
```
    否则执行

```shell
sudo mkdir -p /var/log/swift
```

d. 创建日志目录，启动syslog
shell sudo chown -R syslog.adm /var/log/swift sudo chmod -R g+w /var/log/swift sudo service rsyslog restart

• 配置每一个节点

  a. （可选）删除已经存在的swift目录

  sudo rm -rf /etc/swift
  

  b. 往/etc/swift中加配置文件

  cd $HOME/swift/doc; sudo cp -r saio/swift /etc/swift; cd -
  sudo chown -R ${USER}:${USER} /etc/swift
  

  c. 在Swift config中更新引用

  find /etc/swift/ -name \*.conf | xargs sudo sed -i "s//${USER}/"
  

10. 创建运行Swift的脚本
    a. 复制SAIO脚本，重新设置环境

    mkdir -p $HOME/bin
    cd $HOME/swift/doc; cp saio/bin/* $HOME/bin; cd -
    chmod +x $HOME/bin/*
    

    b. 编辑$HOME/bin/resetswift脚本

    echo "export SAIO_BLOCK_DEVICE=/srv/swift-disk" >> $HOME/.bashrc
    c. 安装测试用的简单配置文件
    
    ```shell
    cp $HOME/swift/test/sample.conf /etc/swift/test.conf
    

    d 添加运行测试用的环境变量

    echo "export SWIFT_TEST_CONFIG_FILE=/etc/swift/test.conf" >> $HOME/.bashrc
    

    e 确保把bin目录设置到环境变了中去

    echo "export PATH=${PATH}:$HOME/bin" >> $HOME/.bashrc
    

    f. source 一下刚刚设置环境变量，使其生效

    . $HOME/.bashrc
    

    g. 创建初始化rings

    remakerings
    

    h. xx
    i. 运行单元测试

    $HOME/swift/.unittests
    

    j. 启动Swift的主线程,分别包括（proxy, account, container, and object）这几个进程

    startmain
    

    k. 获取X-Storage-Url和X-Auth-Token

    curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing' http://127.0.0.1:8080/auth/v1.0
    

    l. 检查能否获得account

    curl -v -H 'X-Auth-Token: ' 
    

    m. 检查python-swiftclient提供的swift命令是否可以用

    swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing stat
    

    n. 验证unctional tests的运行

    $HOME/swift/.functests
    

    o. 验证probe tests的运行

    $HOME/swift/.probetests
