运维自动化实践笔记

由两部分组成，BS架构的OMserver作为UI客户端交互和saltstack作为主控端服务。

选择saltstack的原因
1. 基于Python，便于二次开发
2. saltstack使用消息队列zeroMQ传输数据，更快更稳，ansible基于ssh协议传输数据
3. 使用salt-ssh 安装 salt-minion ，平衡了ansible 不需要安装代理的优势

搭建OMserver脚本如下:

function install_pcre(){
    wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz
    tar zxvf pcre-8.40.tar.gz 
    cd pcre-8.40
    ./configure
    make && make install
echo "################################# install pcre success"
    cd ..
    }

function install_nginx(){
    wget http://nginx.org/download/nginx-1.5.9.tar.gz
    tar zxvf nginx-1.5.9.tar.gz 
    cd nginx-1.5.9
    ./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-cc-opt='-O3' --with-cpu-opt=opteron
    make
    make install
echo "################################# install nginx success"
    cd ..
}

function install_uwsgi(){
    wget http://projects.unbit.it/downloads/uwsgi-2.0.4.tar.gz
    tar zxvf uwsgi-2.0.4.tar.gz 
    cd uwsgi-2.0.4
    ls
    make 
    cp uwsgi /usr/bin

    ln -s /usr/local/lib/libpcre.so.1 /lib64
echo "################################# install pcre success"
    cd ..
}


function install_django(){
    wget --no-check-certificate https://www.djangoproject.com/m/releases/1.4/Django-1.4.9.tar.gz
    tar zxvf Django-1.4.9.tar.gz 
    cd Django-1.4.9
    python setup.py install
echo "################################# install django success"
    cd ..
}
function install_mysql_python(){
    wget  https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c
    unzip MySQL-python-1.2.5.zip
    cd MySQL-python-1.2.5
    python setup.py install
    cd ..
}

function install_django_debug_toolbar(){
    wget https://github.com/robhudson/django-debug-toolbar/archive/master.zip
    mv master.zip django-debug-toolbar.zip
    unzip django-debug-toolbar.zip 
    cd django-debug-toolbar-master/
    python setup.py  install
    cd ..
}
