esxi安装部署

kvm虚拟机迁移到esxi上

直接使用qemu-img convert 转换为vmdk镜像是无法从ESXI中启动的.

首先使用qemu-img 转换镜像为vmdk.

qemu-img convert -f qcow2 oldimage.qcow2 -O vmdk newimage.vmdk

将该镜像上传至Vmware存储.使用vmkfstools重制镜像

 vmkfstools -i oldimage.vmdk newimage.vmdk -d thin

kvm图形化管理工具部署

1.初始化
rm -rf /etc/yum.repos.d/*
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2.安装python依赖
yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor gcc python-devel
python -m pip install --upgrade --force pip -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install setuptools==33.1.1 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple


3.安装python的Django环境
cd /opt/
git clone git://github.com/retspen/webvirtmgr.git
cd webvirtmgr
pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
./manage.py syncdb
./manage.py collectstatic

4.安装Nginx
cat>/etc/yum.repos.d/nginx.repo<<EOF
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/\$releasever/\$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/\$releasever/\$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
EOF
yum makecache fast
yum install nginx -y
yum clean all 

5.配置Nginx和代码
mkdir /code
mv /opt/webvirtmgr /code/
chown -R nginx:nginx /code
rm -rf /etc/nginx/conf.d/default.conf
cat >/etc/nginx/conf.d/webvirtmgr.conf<<EOF
server {
    listen 80 default_server;

    server_name localhost;
    access_log /var/log/nginx/webvirtmgr_access_log; 

    location /static/ {
        root /code/webvirtmgr;        
        expires max;
    }
    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header X-Real-IP \$remote_addr;
        proxy_set_header X-Forwarded-for \$proxy_add_x_forwarded_for;
        proxy_set_header Host \$host:\$server_port;
        proxy_set_header X-Forwarded-Proto \$scheme;
        proxy_connect_timeout 600;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        client_max_body_size 1024M; 
    }
}
EOF
nginx -t
nginx
netstat -lntup|grep 80

6.配置Supervisor
cat >/etc/supervisord.d/webvirtmgr.ini<<EOF
[program:webvirtmgr]
command=/usr/bin/python /code/webvirtmgr/manage.py run_gunicorn -c /code/webvirtmgr/conf/gunicorn.conf.py
directory=/code/webvirtmgr
autostart=true
autorestart=true
logfile=/var/log/supervisor/webvirtmgr.log
log_stderr=true
user=nginx

[program:webvirtmgr-console]
command=/usr/bin/python /code/webvirtmgr/console/webvirtmgr-console
directory=/code/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr-console.log
redirect_stderr=true
user=nginx

[program:nginx]
command=nginx -g 'daemon off;'
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/nginx.log
redirect_stderr=true
EOF
sed -i "s#nodaemon=false#nodaemon=true#g" /etc/supervisord.conf
supervisord -c /etc/supervisord.conf
重新打开一个终端
supervisorctl status

7.创建用户
mkdir /var/cache/nginx/.ssh/ -p
chown -R nginx:nginx /var/cache/nginx/
su - nginx -s /bin/bash
ssh-keygen
touch ~/.ssh/config && echo -e "StrictHostKeyChecking=no\nUserKnownHostsFile=/dev/null" >> ~/.ssh/config
chmod 0600 ~/.ssh/config
ssh-copy-id root@10.0.0.113（需要管理的kvm机器的ip地址）
