2 管理机操作

1.1 优化脚本（提前克隆并优化好所有虚拟机，管理机配置好yum源，除lb服务器外都一块网卡 lb服务器两块网卡）
    cat > /etc/hosts <<EOF
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

    172.16.1.8      web02
    172.16.1.9      web03
    172.16.1.51     db01
    172.16.1.31     nfs
    172.16.1.41     backup
    172.16.1.61     m01
    ########################################
    EOF
    管理机更新yum源
    wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
    wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
1.2 ssh秘钥分发脚本 使得管理机可以通过ssh秘钥直接连入其他服务器
    cat > /server/scripts/fenfa.sh <<EOF
    #!/bin/bash
    . /etc/init.d/functions
    rm -rf ~/.ssh/*
    ssh-keygen -q -N ""  -f ~/.ssh/id_rsa

    do 
        sshpass -p 123456 ssh-copy-id "-i ~/.ssh/id_rsa.pub -o StrictHostKeyChecking=no root@172.16.1.$i" &>/dev/null
    if [ $? -eq 0 ];then
        action "copy-$i"  /bin/true
    else
        action "copy-$i" /bin/false
    fi
    done
    EOF
1.3 搭建vpn脚本
    cat /server/scripts/vpn.sh
    yum install pptpd -y
    sed -i 's#net.ipv4.ip_forward = 0#net.ipv4.ip_forward = 1#g'  /etc/sysctl.conf
    sysctl -p
    echo "localip 10.0.0.61
    remoteip 172.16.1.1-100" >>/etc/pptpd.conf
    echo "oldboy * 123456 *" >> /etc/ppp/chap-secrets
    /etc/init.d/pptpd start
    chkconfig pptpd on
1.4 安装ansible脚本 
    cat /server/scripts/ansible.sh
    #!/bin/bash
    yum install -y ansible 
    #cd /etc/ansible/
    cat >> /etc/ansible/hosts <<EOF

    [web]
    172.16.1.9
    172.16.1.8
    EOF
    mkdir /etc/ansible/playbook/
    
1.5 搭建yum仓库服务端脚本（并手动上传之前打包好的rpm包）
    cat /server/scripts/yum_server.sh
    #!/bin/bash
    mkdir -p /application/yum/centos6/x86_64/
    cd /application/yum/centos6/x86_64/ 
    yum -y install createrepo
    yum install -y --downloaddir=/application/yum/centos6/x86_64/ --downloadonly memcached lrzsz libevent nc livevent-devel keepalived sshpass rpcbind nfs-utils  pcre-devel openssl-devel perl-Module-Install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel libmcrypt-devel mhash mcrypt

    createrepo --update /application/yum/centos6/x86_64/ 
    python -m SimpleHTTPServer 80 &>/dev/null & 
    
1.6 搭建yum仓库客户端脚本
    cat /server/scripts/yum_client.sh
    #!/bin/bash
    cat > /etc/yum.repos.d/CentOS-Base.repo << EOF
    [oldboy]
