1. Prepare the environment
Version 1.1
Linux: Ubuntu Server 12.04.1 LTS;
Swift version: 1.0 (installed later );
Python version: 2.7.3 (later installation );
Python-swiftclient version: 1.3.0 (installed later ).
Summary of the installation and testing of a single Swift node in UbuntuHttp://www.linuxidc.com/Linux/2014-02/97348.htm
1.2 node IP
Proxy Node IP: 172.17.10.14;
Storage Node 1 IP: 172.17.10.10 (with 2 2 TB Storage devices );
Storage Node 2 IP: 172.17.10.11 (with 1 2 TB Storage device );
Storage Node 3 IP: 172.17.10.13 (with 1 2 TB Storage device ).
1.3 Replace the image (optional)
If the "Network speed is slow" or "software installation fails", you can consider replacing it with a domestic image:
Vsroot @ ubuntu :~ $ Sudo sed-I's # us.archive.ubuntu.com # mirrors.163.com # G'/etc/apt/sources. list
Vsroot @ ubuntu :~ $ Sudo apt-get update
1.4 system time
Vsroot @ ubuntu :~ $ Date # Check whether the system time is correct. If the system time is correct, ignore the following two steps:
Vsroot @ ubuntu :~ $ Sudo date-s "15:05:57" # set the system time
Vsroot @ ubuntu :~ $ Sudo hwclock-w # hardware write time
1.5 disable Firewall
Make sure SELinux is disabled.
Vsroot @ ubuntu :~ $ Sudo ufw disable # disable Firewall
2. General OS Configuration
2.1 create a Swift user on each node
Vsroot @ ubuntu :~ $ Sudo useradd-mk/home/swift-s/bin/bash swift
Vsroot @ ubuntu :~ $ Sudo passwd swift # Set your swift password to swift
Edit/etc/sudoers and add the following content to the end of the file:
Vsroot @ ubuntu :~ $ Sudo vim/etc/sudoers
# User alias specification
Swift ALL = (ALL) NOPASSWD: ALL
Then, you can switch to the swift user for subsequent operations:
Vsroot @ ubuntu :~ $ Su swift
2.2 install the Swift library on each node
Swift @ ubuntu :~ $ Sudo apt-get installpython-software-properties
Swift @ ubuntu :~ $ Sudo add-apt-repository ppa: swift-core/release # ignore this step to report an error
Swift @ ubuntu :~ $ Sudo add-apt-repositorycloud-archive: grizzly # You can also select version H.
Swift @ ubuntu :~ $ Sudo apt-get update
Swift @ ubuntu :~ $ Sudo apt-get install swiftpython-swiftclient openssh-server
2.3 create a Swift working directory on each node
Swift @ ubuntu :~ $ Sudo mkdir-p/etc/swift
Swift @ ubuntu :~ $ Sudo chown-R swift: swift/etc/swift/
2.4 create a Swift configuration file
Create a Swift configuration file on any node:
Swift @ ubuntu :~ $ Cat>/etc/swift. conf <
[Swift-hash]
# Random unique strings that can neverchange (do not lose)
Swift_hash_path_prefix = 'od-t x8-N 8-
Swift_hash_path_suffix = 'od-t x8-N 8-
EOF
Copy the Swift configuration file to all other nodes in sequence:
Swift @ ubuntu :~ $ Scp/etc/swift. conf 172.17.10.10:/etc/swift/
2.5 set IP environment variables on each node
On all Storage nodes, the actual IP address is set as follows:
Swift @ ubuntu :~ $ ExportSTORAGE_LOCAL_NET_IP = 172.17.10.10
Set the following parameters based on the actual IP address on all Proxy nodes:
Swift @ ubuntu :~ $ Export PROXY_LOCAL_NET_IP = 172.17.10.14
Considering that the export command only takes effect for the current session of the current user, you can also write the environment variable to/etc/profile:
Swift @ ubuntu :~ $ Sudo vim/etc/profile
Swift @ ubuntu :~ $ Source/etc/profile # the current session takes effect immediately
2.6 create a Swift service directory and modify the boot configuration file
Swift @ ubuntu :~ $ Sudo mkdir-p/var/run/swift
Swift @ ubuntu :~ $ Sudo chown swift: swift/var/run/swift
Swift @ ubuntu :~ $ Sudo vim/etc/rc. local
Sudo mkdir-p/var/run/swift
Sudo chown swift: swift/var/run/swift
Exit 0
3. Configure Proxy Node
3.1 install the swift-proxy Library
Swift @ ubuntu :~ $ Sudo apt-get installswift-proxy memcached
3.2 Create an SSL self-signed certificate
Swift @ ubuntu :~ $ Cd/etc/swift
Swift @ ubuntu:/etc/swift $ openssl req-new-x509-nodes-out cert. crt-keyout cert. key
Note: The CommonName of the certificate must be set to the IP address of the Proxy Node: 172.17.10.14.
3.3 configure memcached and restart the service
Swift @ ubuntu :~ $ Sudo perl-pi-e "s/-l127.0.0.1/-l $ PROXY_LOCAL_NET_IP/"/etc/memcached. conf
Swift @ ubuntu :~ $ Sudo service memcachedrestart
Check whether the memcached service has been started properly.
3.4 create a Proxy server configuration file
Swift @ ubuntu :~ $ Cat>/etc/swift/proxy-server.conf <
[DEFAULT]
Cert_file =/etc/swift/cert. crt
Key_file =/etc/swift/cert. key
Bind_port = 8080
Workers = 8
User = swift
[Pipeline: main]
Pipeline = healthcheck proxy-logging cache tempauth proxy-logging proxy-server
[App: proxy-server]
Use = egg: swift # proxy
Allow_account_management = true
Account_autocreate = true
[Filter: proxy-logging]
Use = egg: swift # proxy_logging
[Filter: tempauth]
Use = egg: swift # tempauth
User_system_root = testpass. admin https: // $ PROXY_LOCAL_NET_IP: 8080/v1/AUTH_system
[Filter: healthcheck]
Use = egg: swift # healthcheck
[Filter: cache]
Use = egg: swift # memcache
Memcache_servers = $ PROXY_LOCAL_NET_IP: 11211
EOF
3.5 create account, container, and object rings
Swift @ ubuntu :~ $ Cd/etc/swift
Sudo swift-ring-builder account. builder create 18 3 1
Sudo swift-ring-builder container. builder create 18 3 1
Sudo swift-ring-builder object. builder create 18 3 1
18 indicates that the number of partition is the 18 power of 2. The number depends on the number of partition you want in a ring. 3 represents the number of copies of each object. The last parameter 1 indicates that a partition can be moved at least one hour later.
3.6 let the ring record the Storage devices of each Storage Node
Export ZONE = 1
Export STORAGE_LOCAL_NET_IP = 172.17.10.10
Export WEIGHT = 100
Export DEVICE = sdb1
Sudo swift-ring-builder account. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6002/$ DEVICE $ WEIGHT
Sudo swift-ring-builder container. builderadd z $ ZONE-$ STORAGE_LOCAL_NET_IP: 6001/$ DEVICE $ WEIGHT
Sudo swift-ring-builder object. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6000/$ DEVICE $ WEIGHT
Export ZONE = 1
Export STORAGE_LOCAL_NET_IP = 172.17.10.10
Export WEIGHT = 100
Export DEVICE = sdc1
Sudo swift-ring-builder account. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6020/$ DEVICE $ WEIGHT
Sudo swift-ring-builder container. builderadd z $ ZONE-$ STORAGE_LOCAL_NET_IP: 6010/$ DEVICE $ WEIGHT
Sudo swift-ring-builder object. builder add z $ ZONE-$ STORAGE_LOCAL_NET_IP: 6030/$ DEVICE $ WEIGHT
Export ZONE = 2
Export STORAGE_LOCAL_NET_IP = 172.17.10.11
Export WEIGHT = 100
Export DEVICE = sdb1
Sudo swift-ring-builder account. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6002/$ DEVICE $ WEIGHT
Sudo swift-ring-builder container. builderadd z $ ZONE-$ STORAGE_LOCAL_NET_IP: 6001/$ DEVICE $ WEIGHT
Sudo swift-ring-builder object. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6000/$ DEVICE $ WEIGHT
Export ZONE = 3
Export STORAGE_LOCAL_NET_IP = 172.17.10.13
Export WEIGHT = 100
Export DEVICE = sdb1
Sudo swift-ring-builder account. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6002/$ DEVICE $ WEIGHT
Sudo swift-ring-builder container. builderadd z $ ZONE-$ STORAGE_LOCAL_NET_IP: 6001/$ DEVICE $ WEIGHT
Sudo swift-ring-builder object. builder addz $ ZONE-$ STORAGE_LOCAL_NET_IP: 6000/$ DEVICE $ WEIGHT
Note: You need to set this parameter based on the actual Storage device of the Storage Node:
① The DEVICE must follow the/etc/rsyncd on the Storage Node. set path in conf. For example, if path is/srv/node/and the Directory sdb1 exists in/srv/node/, the DEVICE value is sdb1;
② The ZONE starts counting from 1 and increases by 1. When a Storage Node has multiple devices, it can be set to the same ZONE (recommended) or multiple zones;
③ If the size of each Mount partition is the same, WEIGHT (WEIGHT) may be set to 100.
3.7 confirm whether the ring content is correct and the (Rebalance) ring
Swift-ring-builder account. builder
Swift-ring-builder container. builder
Swift-ring-builder object. builder
Sudo swift-ring-builder account. builderrebalance
Sudo swift-ring-builder container. builderrebalance
Sudo swift-ring-builder object. builderrebalance
3.8 copy the ring to all other nodes
Swift @ ubuntu :~ $ Scp/etc/swift/* .ring.gz 172.17.10.10:/etc/swift/
Copy account.ring.gzw.container.ring.gzand object.ring.gz to the/etc/swift directory of all other proxynodes and Storage nodes.
Make sure that the configuration files of all nodes belong to swift users:
Swift @ ubuntu :~ $ Sudo chown-R swift: swift/etc/swift
3.9 enable Proxy service
Swift @ ubuntu :~ $ Sudo swift-init proxy start
