Shell脚本-自动化部署反向代理、WEB、nfs

部署nginx反向代理三个web服务，调度算法使用加权轮询(由于物理原因只开启两台服务器)

AutoNginxNfsService.sh

#/bin/bash
systemctl status nginx
if(($?==))
    then
    yum install -y nginx
    if(($?==))
        then
        #echo 'Yes!'
        systemctl start nginx
        if(($?==))
            then
            echo "Congratulations!! Nginx start OK!!"
        else
            echo "Sorry is Fail!!!"
        fi
    else
        echo"sorry install is Fail!!!"

    fi
elif(($?==))
    then
    systemctl start nginx
    if(($?==))
        then

    else
        echo "sorry!!"
    fi
elif(($?==))
    then
    echo "OKOKOK!!!"
else
    echo "I am so sorry"
fi
echo "config writing...."
grep 'upstream' /etc/nginx/nginx.conf
if(($?!=))
    then
    sed -ri '/^http/a upstream Yanlong {' /etc/nginx/nginx.conf
    sed -ri '/^upst/a server yanlongweb1 weight=3\;' /etc/nginx/nginx.conf
    sed -ri '/^server yanlongweb1/a server yanlongweb2\;' /etc/nginx/nginx.conf

echo "config write is OK!"
systemctl reload nginx
if(($?==))
    then
    echo "HTTP load balancer is OK!"
else
    echo "Sorry!!"

systemctl status nfs
if(($?==))
    then
    yum install rpcbind nfs-utils -y
    if(($?==))
        then
        #echo 'Yes!'
        systemctl start nfs
        if(($?==))
            then
            echo "Congratulations!! nfs start OK!!"
        else
            echo "Sorry is Fail!!!"
        fi
    else
        echo"sorry install is Fail!!!"

    fi
elif(($?==))
    then
    systemctl start nfs
    if(($?==))
        then
        echo "Congratulations!! nfs start OK!!!"
    else
        echo "sorry!!"
    fi
elif(($?==))
    then
    echo "OKOKOK!!!"
else
    echo "I am so sorry"
fi
echo "config writing...."
echo "/webindex 192.168.16.0/24(rw,sync,fsid=0)" > /etc/exports
echo "config write is OK!"
systemctl reload nfs
if(($?==))
    then
    echo "NFS service is OK!"
else
    echo "Sorry!!"
fi

所有web服务使用共享存储nfs，保证所有web都对其有读写权限，保证数据一致性

systemctl status nginx

                        then
                        echo "Congratulations!! Nginx start OK!!"
