    Nginx+PHP(FastCGI)+MySQL在小内存VPS(t1.micro)上的安装配置与优化

    背景介绍：
    以前，因为AWS EC2的价格比较昂贵而租用了其它国外小厂商的VPS，在使用了3年多之后，发现AWS EC2的价格居然比现在正在使用的VPS要便宜很多。
    全球线路与速度最理想的日本节点的t1.micro型号，选择3年长期合约的价格在2500元人民币左右，一年下来也不到900元，所以就打算将Blog迁移到AWS EC2上。
    之前在部署VPS环境的时候，基本上是完整的参考了张宴的两篇文档，包括操作系统的选择也是相同的。

    但这一次我想采用目前较新的CentOS 6.4 minimal x86_64。
    同时选择版本最新的Nginx，PHP以及MySQL，引入EPEL仓库来简化安装与部署过程中对额外的依赖软件的安装，优化一些原来的工作方式，比如创建服务管理脚本来启动/停止Nginx与MySQL，使用logrotate来切割日志等；
    经过了一番折腾，在填了不少的坑之后，终于成功的完成了新环境的部署，感觉非常不错。

    下面，就是此次的整个安装配置过程：
    1. 安装常用工具
    yum install -y vim wget unzip screen tree mlocate

    2. 安装编译工具
    yum install -y gcc gcc-c++ autoconf patch cmake automake

    3. 安装EPEL仓库
    yum install -y http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

    4. 安装所有必需的软件包
    yum install -y libjpeg-turbo libjpeg-turbo-devel libpng libpng-devel freetype freetype-devel
    yum install -y libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel gmp gmp-devel
    yum install -y bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel unixODBC unixODBC-devel
    yum install -y krb5-libs krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel
    yum install -y libgcrypt libgcrypt-devel libtool
    yum install -y libmcrypt libmcrypt-devel mhash mhash-devel mcrypt pcre pcre-devel
    yum install -y ImageMagick ImageMagick-devel

    9.7 启动Nginx服务
    /webserver/init.d/nginx start

    10. 优化系统内核参数
    vim /etc/sysctl.conf

    01 # For Nginx
    02 net.ipv4.tcp_max_syn_backlog = 65536
    03 net.core.netdev_max_backlog = 32768
    04 net.core.somaxconn = 32768
    05 net.ipv4.tcp_timestamps = 0
    06 net.ipv4.tcp_synack_retries = 2
    07 net.ipv4.tcp_syn_retries = 2
    08 net.ipv4.tcp_tw_recycle = 1
    09 net.ipv4.tcp_tw_reuse = 1
    10 net.ipv4.ip_local_port_range = 1024 65535

    sysctl -p

    vim /etc/security/limits.conf

    1 * - nofile 32768
    2 * - nproc 32768

    11. 创建交换分区
    dd if=/dev/zero of=/opt/swapfile bs=1M count=256
    mkswap /opt/wapfile
    swapon /opt/swapfile

    vi /etc/fstab

    1 /opt/swapfile swap swap defaults 0 0

    12. 配置logrotate切割日志
    yum install -y logrotate
    vim /etc/logrotate.d/blog

    01 /webserver/blog/logs/rainbow_access.log
    02 /webserver/blog/logs/eric_access.log
    03 {
    04 daily
    05 rotate 7
    06 missingok
    07 notifempty
    08 dateext
    09 sharedscripts
    10 postrotate
    11 if [ -f /webserver/nginx/run/nginx.pid ];``then
    12 /bin/``kill -HUP `/bin/```cat`/webserver/nginx/run/nginx.pid“`
    13 fi
    14 endscript
    15 }

    13. 结束
