一、安装
1、更新系统
原来是centos4.5
#yum update
升级后到6.7版本。
[root@localhost ~]# cat /etc/redhat-release CentOS release 6.7 (Final)
2、新建用户
#adduser liuxiaoyan #passwd liuxiaoyan
3、安装snapshot库（root用户）
[root@localhost ~]# yum -y install http://resources.ovirt.org/releases/ovirt-release/ovirt-release35.rpm
4、安装图形显示包（root用户）
[root@localhost ~]# yum -y install mailcap
5、安装第三方包（3rd party packages）（root用户）
[root@localhost ~]# yum install openssl m2crypto python-psycopg2 python-cheetah python-daemon libxml2-python unzip
应该是如果不成功再安装下面安装办法装。--nogpgcheck代表不检查签名。
# yum install python-daemon （--nogpgcheck）
6、安装jdk(root用户)
[root@localhost ~]# yum install -y java-1.7.0-openjdk-devel
7、安装git
[root@localhost ~]# yum install -y git
8、安装ovirt包
[root@localhost ~]# yum install wget
[root@localhost ~]# yum install ovirt-host-deploy
安装时遇到一个问题：
[root@localhost ~]# yum install -y ovirt-host-deploy Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.skyshe.cn * extras: mirrors.skyshe.cn * ovirt-3.5-epel: mirror01.idc.hinet.net * ovirt-3.5-jpackage-6.0-generic: ftp.heanet.ie * ovirt-3.5-pre: resources.ovirt.org * updates: mirrors.skyshe.cn Resolving Dependencies --> Running transaction check ---> Package ovirt-host-deploy.noarch 0:1.3.2-1.el6 will be installed --> Processing Dependency: otopi for package: ovirt-host-deploy-1.3.2-1.el6.noarch --> Finished Dependency Resolution Error: Package: ovirt-host-deploy-1.3.2-1.el6.noarch (ovirt-3.5-pre) Requires: otopi You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest
所以用--skip-broken跳过该问题。
[root@localhost ~]# yum install -y ovirt-host-deploy --skip-broken Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.skyshe.cn * extras: mirrors.skyshe.cn * ovirt-3.5-epel: mirror01.idc.hinet.net * ovirt-3.5-jpackage-6.0-generic: ftp.heanet.ie * ovirt-3.5-pre: resources.ovirt.org * updates: mirrors.skyshe.cn Resolving Dependencies --> Running transaction check ---> Package ovirt-host-deploy.noarch 0:1.3.2-1.el6 will be installed --> Processing Dependency: otopi for package: ovirt-host-deploy-1.3.2-1.el6.noarch Packages skipped because of dependency problems: ovirt-host-deploy-1.3.2-1.el6.noarch from ovirt-3.5-pre
跳过了这个问题。
[root@localhost ~]# yum install http://resources.ovirt.org/releases/ovirt-release/ovirt-release35-snapshot.rpm
9、安装maven (liuxiaoyan用户)
在https://maven.apache.org/download.cgi目录下载apache-maven-3.3.3-bin.tar.gz。
然后解压。
[liuxiaoyan@localhost ~]$ tar -xvf apache-maven-3.3.3-bin.tar.gz
[liuxiaoyan@localhost ~]$ export PATH=$HOME/apache-maven-3.3.3/bin:$PATH [liuxiaoyan@localhost ~]$ mvn -version Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00) Maven home: /home/liuxiaoyan/apache-maven-3.3.3 Java version: 1.7.0_85, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85.x86_64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "2.6.32-358.el6.x86_64", arch: "amd64", family: "unix"
Maven 自定义配置
[liuxiaoyan@localhost ~]$ mkdir ~/.m2 [liuxiaoyan@localhost ~]$ cat > ~/.m2/settings.xml <<"EOT" <settings xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <!--**************************** PROFILES ****************************--> <activeProfiles> <activeProfile>oVirtEnvSettings</activeProfile> </activeProfiles> <profiles> <profile> <id>oVirtEnvSettings</id> <properties> <jbossHome>${env.JBOSS_HOME}</jbossHome> <JAVA_HOME>${env.JAVA_HOME}</JAVA_HOME> </properties> </profile> </profiles> </settings> EOT
10、安装jboss(root用户)
安装：
[root@localhost ~]# yum install jboss-as
下载非常慢，可到http://resources01.phx.ovirt.org/releases/stable/rpm/EL/6/x86_64/
下载
然后安装：
[root@localhost ~]# ls anaconda-ks.cfg install.log install.log.syslog jboss-as-7.1.1-11.el6.x86_64.rpm [root@localhost ~]# rpm -ivh jboss-as-7.1.1-11.el6.x86_64.rpm Preparing... ########################################### [100%] 1:jboss-as ########################################### [100%]
运行jboss
[root@localhost ~]# /usr/share/jboss-as/bin/standalone.sh
设置环境变量
[root@localhost ~]# export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk.x86_64 [root@localhost ~]# export JBOSS_HOME=/usr/share/jboss-as [root@localhost ~]# export PATH=$HOME/apache-maven-3.2.1/bin:$PATH
11、安装PostgreSQL DB (root用户)
[root@localhost ~]# yum install –y postgresql-server
初始化数据库
[root@localhost ~]# service postgresql initdb Initializing database: [ OK ]
重启
[root@localhost ~]# /etc/init.d/postgresql restart Stopping postgresql service: [ OK ] Starting postgresql service: [ OK ]
修改数据库连接
[root@localhost ~]# vi /var/lib/pgsql/data/pg_hba.conf
默认：
# TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all ident # IPv4 local connections: host all all 127.0.0.1/32 ident # IPv6 local connections: host all all ::1/128 ident
做如下修改：【ps:如果后期有问题，可将ident,password,password都修改为trust】
# TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all ident # IPv4 local connections: host all all 127.0.0.1/32 password # IPv6 local connections: host all all ::1/128 password
重启：# /etc/init.d/postgresql restart
如果重启失败解决方案可参考：service postgresql initdb [FAILED]
创建数据库
[root@localhost data]# su - postgres -c "psql -d template1 -c \"create user engine password 'engine';\"" CREATE ROLE [root@localhost data]# su - postgres -c "psql -d template1 -c \"create database engine owner engine template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';\"" CREATE DATABASE
12、下载ovirt engine代码
cd $HOME
$ git clone https://github.com/oVirt/ovirt-engine.git
13、编译（必须在ovirt-engine目录下）
make install-dev PREFIX="$HOME/ovirt-engine"
14、Setup
$ $HOME/ovirt-engine/bin/engine-setup
15、启动服务
$HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start
二、排错
1、编译过程排错
错误1：
编译报错如下
Building locales requires more than 10240 available file descriptors, currently 1024 Refer to README.developer for further instructions
解决办法：
查看README.developer中
$ vi README.developer
有如下一段话；
Build locales requires at least 10240 file descriptors, create the following file, replace <user> with user that is used for building, and logout/login: /etc/security/limits.d/10-nofile.conf --- <user> hard nofile 10240 #<user> soft nofile 10240 # optional, to apply automatically --- If soft limit was not set, before building, apply new limit using: $ ulimit -n 10240 POSTGRESQL ACCESSIBILITY
普通用户执行ulimit –n 10240会报错：-bash: ulimit: open files: cannot modify limit: Operation not permitted
所以使用Root su到普通用户再执行ulimit -n 10240，这会使得仅仅在某个会话中生效，在该会话中编译通过。
如果还是不能解决问题参考README.developer中的提示。
错误2：
make[2]: mvn: Command not found
make[2]: *** [maven] Error 127
解决办法：
执行：
[liuxiaoyan@localhost ~]$ export PATH=$HOME/apache-maven-3.3.3/bin:$PATH
再执行mvn -version能显示版本信息即oK。
错误3：
编译过程中下载maven-ear-plugin-2.8.pom包一个下载不下来，然后就再次尝试下载。。。编译过不去，信息如下
Downloading: http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-ear-plugin/2.8/maven-ear-plugin-2.8.pom
Aug 31, 2015 9:37:09 PM org.apache.maven.wagon.providers.http.httpclient.impl.execchain.RetryExec execute

Aug 31, 2015 9:54:14 PM org.apache.maven.wagon.providers.http.httpclient.impl.execchain.RetryExec execute
INFO: Retrying request to {}->http://repo1.maven.org:80
解决办法:
下载好安装在目录：
.m2/repository/org/apache/maven/plugins/maven-ear-plugin/2.8/maven-ear-plugin-2.8.pom中，所以可以拷贝一份扔进去。
现在下载了一部分时目录是这样的：
[liuxiaoyan@localhost 2.8]$ ls
maven-ear-plugin-2.8.pom.part maven-ear-plugin-2.8.pom.part.lock
拷贝这些文件：
[liuxiaoyan@localhost 2.8]$ ls
maven-ear-plugin-2.8.jar maven-ear-plugin-2.8.jar.sha1 maven-ear-plugin-2.8.pom maven-ear-plugin-2.8.pom.sha1 _remote.repositories
重新编译OK。
2、SetUP过程排错
错误1：
[liuxiaoyan@localhost bin]$ ./engine-setup
./engine-setup: line 81: /usr/sbin/otopi: No such file or directory
解决方法：
拷贝一个otopi文件即可（长久考虑，有可能是因为没装otopi这个包，安装即可）。
错误2：
[liuxiaoyan@localhost bin]$ ./engine-setup
/usr/bin/python: No module named otopi
解决方法：
[root@localhost ~]# yum -y install otopi
错误3：
[liuxiaoyan@localhost bin]$ ./engine-setup
***L:ERROR Internal error: No module named psycopg2
解决方法：
[root@localhost ~]# yum -y install python-psycopg2
错误4：
[ ERROR ] Host name is not valid: Command 'dig' is required but missing
Host fully qualified DNS name of this server [localhost.localdomain]: 10.1.101.51
[ ERROR ] Host name is not valid: 10.1.101.51 is an IP address and not a FQDN. A FQDN is needed to be able to generate certificates correctly.
Host fully qualified DNS name of this server [localhost.localdomain]:
解决方法：
在/etc/hosts中绑定IP和名字，如下：
10.1.101.119 engine //这里的engine是hostname
错误5:
[ ERROR ] Host name is not valid: Command 'dig' is required but missing
Host fully qualified DNS name of this server [engine]: engine
解决办法：
# yum -y install bind-utils
错误6：
[ ERROR ] Cannot connect to Engine database: Cannot connect to database: could not connect to server: Connection refused Is the server running on host "localhost" and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused Is the server running on host "localhost" and accepting TCP/IP connections on port 5432?
解决办法：
Root用户执行：
[root@engine ~]# /etc/init.d/postgresql restart
Stopping postgresql service: [ OK ]
Starting postgresql service: [ OK ]
错误7：
[ ERROR ] Cannot connect to Engine database: Cannot connect to database: FATAL: password authentication failed for user "engine" FATAL: password authentication failed for user "engine"
解决方法：
修改vi /var/lib/pgsql/data/pg_hba.conf
中的密码为trust即可。
在编译目录ovirt-engine/etc/ovirt-engine/engine.conf.d中有一个README
vi /home/liuxiaoyan/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.conf
可能是相关配置文件。
3、start过程排错
错误1：
……/ovirt-engine.py start访问报错：
解决办法：
Root用户关闭防火墙即可。
[root@engine ~]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
错误2：
界面样式错乱
解决方法：
有些rpm包没有安装。
最主要的是一个patternfly1的包没有装。
通过# yum -y install patternfly1安装即可。
如果不行将所有未安装的包都安装一遍，具体参考项目目录下的README.developer。
安装pyflakes-0.4.0-2.el6.noarch
从下面地址下载pyflakes-0.4.0-2.el6.noarch
http://cbs.centos.org/koji/buildinfo?buildID=753
错误3：
[liuxiaoyan@engine ovirt-engine]$ $HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:750]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ovirt-engine[22588] ERROR run:532 Error: process terminated with status code -6
解决办法：
有进程在用8080端口，kill掉即可。
使用ps –a或者netstat命令。
错误4：
解决办法：
root用户执行：/usr/share/jboss-as/bin/standalone.sh启动jboss服务即可。
错误5：
登录时用户名密码验证失败，删掉数据库，重新建一遍
解决办法：
删除数据库engine然后重新创建。
【如果数据库正在被使用就无法删除，此时在root用户下用命令：ps aux|grep engine然后kill掉】
su - postgres -c "psql -d template1 -c \"drop database engine ;\""
su - postgres -c "psql -d template1 -c \"create database engine owner engine template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';\""
错误6：
如果出现服务器的连接不上的情况，可能是端口被占用了。
解决办法：
找到8080端口，kill掉进程，然后重新start即可。
