ovirt-engine安装

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

--> 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

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)

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: I/O exception (java.net.SocketException) caught when processing request to {}->http://repo1.maven.org:80: Connection timed out

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：

http://10.1.101.119:8080/

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。
