CentOS7 minimal ovirt engine 开发环境搭建

注：列出软件包信息：yum info 名字

1. 关闭firewall 和 selinux

2. 添加源epel-方法二
   注：添加之前请看Bug 1572434

3. 添加源ovirt(自动，2 3任选一个)
   yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
   注：这个源目前是ovirt-release42-4.2.2-6版本的
   注：根据需求选择源

4. 添加源ovirt(手动)
   vi /etc/yum.repos.d/ovirt-snapshots.repo

[ovirt-snapshots]
name=local
baseurl=http://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el$releasever
enabled=1
gpgcheck=0
priority=10

[ovirt-snapshots-static]
name=local
baseurl=http://resources.ovirt.org/pub/ovirt-master-snapshot-static/rpm/el$releasever
enabled=1
gpgcheck=0
priority=10

4. 安装包

yum install -y ovirt-ansible-roles ovirt-engine-metrics ovirt-host-deploy ovirt-js-dependencies ovirt-setup-lib ovirt-engine-wildfly ovirt-engine-wildfly-overlay

• 数据库

1. 安装 postgresql 9.5
   yum localinstall https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-3.noarch.rpm
yum -y install postgresql95-server postgresql95-contrib
2. 初始化
   /usr/pgsql-9.5/bin/postgresql95-setup initdb
3. 配置
   vi /var/lib/pgsql/9.5/data/pg_hba.conf

# IPv4 local connections:
host    all             all             127.0.0.1/32            password
# IPv6 local connections:
host    all             all             ::1/128                 password

3. 配置
   vi /var/lib/pgsql/9.5/data/postgresql.conf

autovacuum_vacuum_scale_factor = 0.01
autovacuum_analyze_scale_factor = 0.075
autovacuum_max_workers = 6
max_connections = 150
work_mem = 8MB

4. 重启
   systemctl restart postgresql-9.5.service
systemctl enable postgresql-9.5.service
5. 创建数据库

su - postgres -c "psql -d template1 -c \"create user engine with login password 'engine' SUPERUSER;\""

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';\""

6. 用角色engine登录数据库engine

7. 执行数据库执行

DROP FUNCTION IF EXISTS uuid_generate_v1();
CREATE EXTENSION "uuid-ossp";

• git、构建和启动
  注：不要在 root下执行下面命令,因为ovirt只能在非root下进行开发，centos7创建用户

1. 查看用户目录
   echo $HOME
2. checkout到$HOME/git/ovirt-engine
mkdir -p "$HOME/git"
cd "$HOME/git"
git clone https://github.com/oVirt/ovirt-engine.git
   注：现在版本git上版本不是4.2.2.6了，所以就不要clone了，从resource上获取ovirt-engine的源码
3. 更改pom.xml
$HOME/git/ovirt-engine/pom.xml
   所有maven-surefire-plugin都要添加configuration

         maven-surefire-plugin
           
               true
           

4. 构建到 $HOME/ovirt-engine
cd "$HOME/git/ovirt-engine"
make install-dev PREFIX="$HOME/ovirt-engine"
   注：编译过程至少要8G内存
5. 初始化
   $HOME/ovirt-engine/bin/engine-setup
6. 启动
   $HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start

• 查看

1. 导入证书
   下载证书：https://localhost.localdomain/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
   浏览器导入证书
2. 登录查看
   https://localhost.localdomain:8443/ovirt-engine/
   编辑打开网址的主机的hosts：

IP localhost.localdomain

IP是运行ovirt-engine的centos7的ip

• 编译出ovirt-engine

su
echo 8192000 > /proc/sys/fs/inotify/max_user_watches
ulimit -n 10240
su coretek
ulimit -n 10240
make dist
rpmbuild -tb ovirt-engine-4.2.3.5.tar.gz
或
rpmbuild -D"ovirt_build_minimal 1" -tb ovirt-engine-4.2.3.5.tar.gz

额外的：

• 添加添加用户密码登录的模块（就是aaa）

• 前后端代码调试
