CentOS7 minimal ovirt engine 本地开发环境搭建

注：本文档的ovirt-engine版本是4.2.3.5，使用用户是coretek

1. 先决条件

• 安装操作系统

1. 安装CentOS-7-x86_64-DVD-1804.iso，选择GNOME
2. 创建用户coretek

• 关防火墙

1. 停止firewall：
   systemctl stop firewalld.service
2. 禁止firewall开机启动：
   systemctl disable firewalld.service
3. 停止 NetworkManager：
   systemctl stop NetworkManager
4. 禁止NetworkManager：
   systemctl disable NetworkManager
   注：关闭NetworkManager 会导致自动网络如无线网失败
5. 关闭 selinux
vi /etc/selinux/config

#SELINUX=enforcing
SELINUX=disabled

6. 重启

• 解压包

1. 创建目录
   mkdir /opt/setup
cd /opt/setup
2. 解压rpm
   tar xzvf ovirt-engine-4.2.3.5-devel-pkg-201806101842.tar.gz
   注：svn路径：svn://192.168.0.199/Delta8/trunk/rpms/ovirt-engine-4.2.3.5-devel/ovirt-engine-4.2.3.5-devel-pkg-201806101842.tar.gz
3. 本地源
   mv ovirt-engine-4.2.3.5-devel.repo /etc/yum.repos.d/
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/CentOS-* /etc/yum.repos.d/bak/
yum makecache

2. 安装

• 安装依赖

1. 安装
   yum install -y pyflakes exportfs python-cheetah git java-devel java-1.8.0-openjdk-devel mailcap unzip openssl bind-utils python-dateutil m2crypto python-psycopg2 python-jinja2 libxml2-python python-daemon maven ansible python-flake8 python-pep8 python-docker-py python2-isort otopi ant ovirt-ansible-roles ovirt-engine-metrics ovirt-host-deploy ovirt-js-dependencies ovirt-setup-lib ovirt-engine-wildfly ovirt-engine-wildfly-overlay install postgresql95-server postgresql95-contrib tigervnc-server

• 配置数据库

1. 初始化

/usr/pgsql-9.5/bin/postgresql95-setup initdb

2. 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';\""

• 配置数据库允许engine登录和远程登录

1. 设置centos用户 postgres的密码为postgres
passwd postgres
2. 配置数据库用户postgres的密码为postgres
su postgres
psql
ALTER USER postgres WITH PASSWORD 'postgres';
3. 配置使用密码登录
   vi /var/lib/pgsql/9.5/data/pg_hba.conf

local   all             all                                     password
host    all             all             192.168.0.103/24            password

2. 配置监听远程登录
   vi /var/lib/pgsql/9.5/data/postgresql.conf

listen_addresses='*'

4. 重启数据库服务
   systemctl restart postgresql-9.5.service
5. 登录数据库
6. 切换数据库
   \c engine
7. 切换角色
   \c - engine
8. 执行数据库命令

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

• 开始（接下来执行命令使用centos用户coretek）

1. 从gitee上取ovirt-engine源码
   mkdir -p "$HOME/git"
cd "$HOME/git"
git clone https://gitee.com/wangkehao/ovirt-engine.git
git clone https://gitee.com/wangkehao/ovirt-engine-extension-aaa-jdbc.git
2. 构建ovirt-engine
cd "$HOME/git/ovirt-engine"
make clean install-dev PREFIX="$HOME/ovirt-engine"
3. 构建ovirt-engine-extension-aaa-jdbc
cp /home/coretek/ovirt-engine/share/ovirt-engine/modules/common/org/ovirt/engine/api/ovirt-engine-extensions-api/main/ovirt-engine-extensions-api.jar /home/coretek/git/ovirt-engine-extension-aaa-jdbc/lib
cd /home/coretek/git/ovirt-engine-extension-aaa-jdbc/
make clean install
4. 初始化
   /home/coretek/ovirt-engine/bin/engine-setup
5. 启动
   $HOME/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start

• idea（使用coretek用户）

1. 安装
   mkdir /home/coretek/opt
cd /home/coretek/opt
tar xzvf ideaIU-2018.1.2.tar.gz
2. 启动
   vncserver
   下面的步骤在远程桌面中执行
   /idea-IU-181.4668.68/bin/idea.sh
3. 注册码（网址形式）：https://www.zengxiaowen.me/idea
