• linux 安装 nginx

    —- install nginx

    # yum install -y httpd-devel pcre perl pcre-devel zlib zlib-devel GeoIP GeoIP-devel
    wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz
    wget http://zlib.net/zlib-1.2.8.tar.gz
    wget http://www.openssl.org/source/openssl-1.0.1m.tar.gz

    ./configure –prefix=/data/lib/zlib-1.2.8
    make & make install

    安装pcre报错You need a C++ compiler for C++ support
    解决办法 sudo apt-get install build-essential

    ./configure –prefix=/data/lib/pcre-8.36
    make & make install

    apt-get install libxml2 libxslt1-dev libxml2-dev
    apt-get install libgd2-xpm-dev
    apt-get install geoip-database libgeoip-dev
    ##apt-get install libpcre3 libpcre3-dev

    yum list | grep geo
    yum install gcc-c++

    # error: C compiler cc is not found
    yum install gcc
    # the HTTP XSLT module requires the libxml2/libxslt
    yum install libxml2-devel libxslt-devel
    # the HTTP image filter module requires the GD library.
    yum install gd-devel
    # the GeoIP module requires the GeoIP library.
    # –with-http_geoip_module
    yum install GeoIP GeoIP-data GeoIP-devel

    #首先定义新的Nginx名称:
    NGINX_BANNER=”superServer”
    #执行更名操作

    sed -i “s#\”NGINX\”#\”$NGINX_BANNER\”#” src/core/nginx.h
    sed -i “s#\”nginx/\”#\”$NGINX_BANNER/\”#” src/core/nginx.h

  • iptables防火墙 只允许某IP访问某端口、访问特定网站

    1.先备份iptables

    # cp /etc/sysconfig/iptables /var/tmp
    需要开80端口,指定IP和局域网
    下面三行的意思:
    先关闭所有的80端口
    开启ip段192.168.1.0/24端的80口
    开启ip段211.123.16.123/24端ip段的80口
    # iptables -I INPUT -p tcp –dport 80 -j DROP
    # iptables -I INPUT -s 192.168.1.0/24 -p tcp –dport 80 -j ACCEPT
    # iptables -I INPUT -s 211.123.16.123/24 -p tcp –dport 80 -j ACCEPT
    以上是临时设置。
    2.然后保存iptables
    # service iptables save
    3.重启防火墙
    #service iptables restart
    ===============以下是转载================================================
    以下是端口,先全部封再开某些的IP
    iptables -I INPUT -p tcp –dport 9889 -j DROP
    iptables -I INPUT -s 192.168.1.0/24 -p tcp –dport 9889 -j ACCEPT
    如果用了NAT转发记得配合以下才能生效
    iptables -I FORWARD -p tcp –dport 80 -j DROP
    iptables -I FORWARD -s 192.168.1.0/24 -p tcp –dport 80 -j ACCEPT

    常用的IPTABLES规则如下:
    只能收发邮件,别的都关闭
    iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -j DROP
    iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p udp –dport 53 -j ACCEPT
    iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p tcp –dport 25 -j ACCEPT
    iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p tcp –dport 110 -j ACCEPT

    将WAN 口NAT到PC
    iptables -t nat -A PREROUTING -i $INTERNET_IF -d $INTERNET_ADDR -j DNAT –to-destination 192.168.0.1

    将WAN口8000端口NAT到192。168。100。200的80端口
