优化LNMP架构采用“Website Baker”为小型公司创建高性能网站方案

参考图片：

一、安装部署各种软件:
1.系统环境:
硬件:HP 360G4/2G
System:Centos 5.4
Web:nginx-1.1.6.tar.gz
FastCGI:php-5.3.8.tar.gz
DB:mysql-5.5.3-m3.tar.gz
2. 安装编译环境
#yum -y install gcc gcc-c++ autoconf automake openssl-devel zlib-devel pcre-devel //pcre让nginx支持正则
#yum -yt groupinstall "Developement Tools" "Development Libraries"

1.编译安装mysql
//a.编译安装mysql的优点：源码包的默认编译参数默认以dubgu模式）给mysql的性能带来很大的损失，
// 此处使用 --without-debug参数禁用debug模式
//b.以静态方式编译（比动态方式提高5%-10%的性能）
// 此处使用 --with-mysqld-ldflgs=--all-staic 和 --with-client-ldflds=--all-staic参数
//c.使用unix套接字链接提高7.5%性能
// 此处使用--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
//d.允许使用汇编模式
// 此处使用 --enable-assembler (优化性能)
//e.至于 --pgcc 目前没有在生产上使用过（据说可以提高1%）
//f.编译安装，可以在同一台服务器上安装多个mysql（前提要保证存放位置、sock不同）
#groupadd mysql                             //为mysql创建用户组
#useradd -g mysql mysql                     //将mysql用户添加到mysql组中
#tar zxvf mysql-5.5.3-m3.tar.gz
#cd mysql-5.5.3-m3
./configure \
--prefix=/usr/local/mysql \
--without-debug \                           //取消debug模式编译
--enable-assembler \
--with-mysqld-ldflags=-all-static \
--with-client-ldflags=-all-static \
--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock \
--with-extra-charsets=utf8,gbk

//如果没有问题则会显示
// Thank you for choosing MySQL!
// 以下时间将为很长，请为mysql创建配置文件或数据目录
#make && make install                           //如果编译安装没有问题则NEXT
#chmod 755 /usr/local/mysql
#chown -R mysql:mysql /usr/local/mysql          //修改安装目录的用户和用户组为mysql
#mkdir -pv /mysql_data/{data,binlog,relaylog}   //为mysql提供数据存放目录
#/usr/local/mysql/bin/mysql_install_db \        //推荐是用其它新分区，避免IO重读/分区
--basedir=/usr/local/mysql \
--datadir=/mysql_data --user=mysql

2.漫长的等待后启动mysql(SysV格式的脚本见附件）
#/usr/local/webserver/mysql/bin/mysql start
//管理mysql并修改密码和给新用户创建权限
#/usr/local/mysql/bin/mysql -u root -p -S /usr/local/mysql/tmp/mysql.sock
enter password: <Enter>              //默认为空
#/usr/local/mysql/bin/mysqladmin -uroot -p paswword 'hanfeng' //创建新密码为hanfeng
--------------------------------------------------
3.编译安装PHP
// 为PHP安装事件触发网络库
#tar zxvf libevent-2.0.15-stable.tar.gz
#cd libevent-2.0.15-stable
#./configure && make && make install
// 为PHP安装字符编码转换
#tar zxvf libconv-1.13.1.tar.gz
#cd libconv-1.13.1
#./configure && make && make install
// 安装FastCGIのPHP
// 此处采用
#tar zxvf php-5.3.8.tar.gz
#cd php-5.3.8
#./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-mysqli==/usr/local/mysql/bin/mysql_config \
--with-openssl \
--enable-fpm \                                 //一定要有
--with-libevent-dir=/usr/local/lib \
--enable-mbstring \
--disable-debug \                              //取消掉debug，为增加性能
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--with-iconv-dir=/usr/local
--------------------------------------------------
4.随后将会看到
// Thank you for using PHP
#ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2        //做个连接防止make时缺少libiconv.so.2
#ln -s /usr/local/lib/libiconv.so.2 /usr/local/libiconv.so.2
#make ZEND_EXTRA_LIBS='-liconv'                                   //iconv库问题
5.漫长时间后将会看到
// Build complete. Don't forget to run 'make test'
#make install
#cp php-5.3.8/php.ini-production /usr/local/php/etc/php.ini
#vi /usr/local/php/etc/php.ini 修改并保存
// 开启以下几项
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
6. 使用nohup在后台启动 php-fpm 为防止tty终端关闭导致php-fpm 挂掉！推荐生产环境使用nohup将命令放于后台运行
#nohup /usr/local/php/sbin/php-fpm &
[1] 18198
nohup: appending output to `nohup.out'
[1]+ Done    nohup /usr/local/php/sbin/php-fpm
//将命令加到开始启动
#echo "nohup /usr/local/php/sbin/php-fpm & > /dev/null" >> /ect/rc.local
7.//为nginx增加fastcgi_params 文件
#vi /etc/nginx/fastcgi.conf    //修改后保存
// 将里面内容替换为
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE    nginx;
fastcgi_param QUERY_STRING       $query_string;
fastcgi_param REQUEST_METHOD     $request_method;
fastcgi_param CONTENT_TYPE       $content_type;
fastcgi_param CONTENT_LENGTH     $content_length;
fastcgi_param SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param REQUEST_URI        $request_uri;
fastcgi_param DOCUMENT_URI       $document_uri;
fastcgi_param DOCUMENT_ROOT      $document_root;
fastcgi_param SERVER_PROTOCOL    $server_protocol;
fastcgi_param REMOTE_ADDR        $remote_addr;
fastcgi_param REMOTE_PORT        $remote_port;
fastcgi_param SERVER_ADDR        $server_addr;
fastcgi_param SERVER_PORT        $server_port;
fastcgi_param SERVER_NAME        $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS    200;

8.为nginx 优化linux内核参数
vi /etc/sysctl.conf                  // 增加一下内容，并是修改生效
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw.reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
net.ipv4.ip_local_port_range = 1024 65535
##########################################
#sysctl -p                           //使其及时生效
--------------------------------------------------
9.编译安装nginx
#useradd -s /sbin/nologin -M nginx       //添加nginx用户
#tar zxvf nginx-1.1.6.tar.gz
#cd nginx-1.1.6
#./configure \
--prefix=/usr/local/nginx \                             //安装路径
--sbin-path=/usr/sbin/nginx \                           //可执行文件路径
--conf-path=/etc/nginx/nginx.conf \                     //最好定义到/etc下
--pid-path=/usr/local/nginx/nginx.pid \                  //pid文件存放位置，后面管理时将会用到
--lock-path=/var/lock/nginx.lock \
--user=nginx \
--group=nginx \
--with-http_stub_status_module \                        //以取得一些网页的运行状态
--with-http_ssl_module \                                //支持https加密连接
--with-http_gzip_static_module \                        //静态缓存、压缩模块
--with-http_realip_module \                            //让nginx透明获取客户端IP
--http-client-body-temp-path=/var/tmp/nginx/client/ \   //指定http客户端请求缓存文件存放目录
--http-proxy-temp-path=/var/tmp/nginx/proxy/ \          //指定http反向代理缓存文件存放目录
--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/           //指定FastCGI缓存文件存放目录
#make && make install                                     //安装nginx
10.编写SystemV风格的启动脚本（可在本文附件下载后直接使用）
//如果需要请参考: http://linuxxx.blog.51cto.com/1824808/705590 有关nginxd脚本的编写
//使用说明，保存nginxd脚本,赋予执行权限，添加服务和开机启动
#chmod +x /etc/init.d/nginxd
#chkconfig --add nginxd
// 如果不支持，则添加一下2行即可
// # chkconfig: - 85 15                #为必须字符
// # description: nginx is a World Wide Web server. It is used to serve
#chkconfig --level 2345 nginxd on
11.第一次启动nginx
#service nginxd start    //没问题的话就显示，也会看到Welcome to nginx!
Starting nginx: [ OK ]
在XP客户端访问一下 http://192.168.10.11   //服务器地址
--------------------------------------------------
12.优化配置nginx.conf 文件
user nginx nginx;
worker_processes 8;                       //我的服务器为双核双线程

pid /usr/local/nginx/nginx.pid; //PID 存在位置，和启用nginx.pid管理

events {
use epoll; //使用的网络IO模型，CeotOs或REAL推荐使用epoll
worker_connections 1024; //允许的连接数
}

http {
include mime.types;
default_type application/octet-stream;

    log_format mylog '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
                       //mylog为自定义log_format的name,log_format用于定义log的格式
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 60; //连接保持时间

    gzip on;                           //开启gzip压缩，为客户端访问节省更大的带宽，提高访问速度
    gzip_min_length 1k;
    gzip_buffers 4 8k;                 //安装原数据8K为单位的4倍申请内存
    gzip_http_version 1.1;             //http版本信息，目前为1.0和1.1
    gzip_comp_level 4;                 //gzip 压缩比（与CPU处理速度相反）
    gzip_types text/plain application/x-javascript text/css application/xml;
    gzip_vary on;

    fastcgi_intercept_errors on;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    fastcgi_buffer_size 64k;
    fastcgi_buffers 4 64k;
    fastcgi_busy_buffers_size 128k;
    fastcgi_temp_file_write_size 128k;

    server {
        listen       80;
        server_name www.abc.com;
        access_log logs/abc.access.log mylog;   //用到了mylog，将日志定义为log_format格式

        location / {
            root   /usr/local/nginx/html/abc;
            index index.php index.html index.htm;
        }

        error_page 404 = /404.html;           //当访问不存在的页面时，提示用户重新访问主页
        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504 /usr/local/nginx/50x/50x.html; //各种错误页面
        location = /50x.html {
            root   html;
        }
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index index.php;                               //fastcgi 索引页格式
            fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }
    }

    server {
        listen       80;
        server_name www.abcd.com;
        access_log logs/abcd.access.log mylog;
        location / {
            root /usr/local/nginx/html/abcd;
            index index.php index.html index.htm;
            error_page 404 = /404.html;
            error_page   500 502 503 504 /usr/local/nginx/50x/50x.html;
        location = /50x.html {

            root   html;
        location ~ \.php$ {
            root   /usr/local/nginx/html/abcd/wb;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }
        }
    }
}
############### This is nginx.conf ###############
--------------------------------------------------
13.使用PID信号来控制管理nginx进程
// pid 存放位置 /usr/local/nginx/nginx.pid
// kill - 信号类型 cat `/usr/local/nginx/nginx.pid`
// 信号类型说明
// TERM,INT 快速关闭nginx ，如以此kill掉8个进程是不是很悲剧
// OUT 从容关闭
// HUP 平滑重启,重新加载配置文件
// USR1 重新打开日志文件，在自动切割日志时比较使用
// USR2 平滑升级可执行程序
// WINCH 从容关闭进程,对于线上的nginx新旧版本更换

// 针对与上文的nginx.conf 修改此处使用HUP信号来控制
#kill -HUP cat `/usr/local/nginx/nginx.pid` //让修改立即生效
14.访问简单测试测试页面
#vi /usr/local/nginx/html/index.php
<?php
phpinfo();
?>

15.测试访问数据库
<?php
link=mysql_connect("localhost","root","hanfeng");
if(!$link) echo "ERROR!";
else echo "OK!";
phpinfo();
?>
--------------------------------------------------
二、安装“Website Baker”
1.安装部署Website Baker
// 采用nginx的虚拟主机为企业N个域名做网站部署
#unzip WebsiteBaker_2.8*.zip
#mv WebsiteBaker_2.8* /usr/local/nginx/html/abc
#cp -r /usr/local/nginx/html/abc /usr/local/nginx/html/abcd
#cd /usr/local/nginx/html/abc
#cp wb/modules/fckeditor/fckeditor/editor/filemanager/connectors/php/config.php ./
#cp config.php ../abcd/wb/
#chmod 777 /usr/local/nginx/html/abc
#chmod 777 /usr/local/nginx/html/abcd
2.为Website Baker的创建数据库用户
#/usr/local/mysql/bin/mysql -uroot -p
mysql> GRANT ALL PRIVILEGES ON abc.* TO 'abc'@'localhost' IDENTIFIED BY 'hanfeng';
mysql> GRANT ALL PRIVILEGES ON abcd.* TO 'abcd'@'localhost' IDENTIFIED BY 'hanfeng';
mysql>flush privileges;
3.通过浏览器访问并install 和admin

IE: http://www.abcd.com/install 安装 (abc.com同理)
