    二、安装PHP 5.2.13(FastCGI模式)

    1.编译安装PHP 5.2.13所需的支持库:

     1 tar zxvf libiconv-1.13.tar.gz
     2 cd libiconv-1.13/
     3 ./configure --prefix=/usr/local
     4 make

    20 tar zxvf mhash-0.9.9.9.tar.gz
    21 cd mhash-0.9.9.9/
    22 ./configure
    23 make
    24 make install
    25 cd ../
    26 
    27 ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
    28 ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
    29 ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
    30 ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
    31 ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
    32 ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
    33 ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
    34 ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

    36 ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
    37 
    38 tar zxvf mcrypt-2.6.8.tar.gz
    39 cd mcrypt-2.6.8/
    40 /sbin/ldconfig
    41 ./configure
    42 make
    43 make install
    44 cd ../
    编译安装PHP 5.2.13所需的支持库

    2.编译安装MySQL 5.5.2-m2

     1 /usr/sbin/groupadd mysql
     2 /usr/sbin/useradd -g mysql mysql
     3 tar zxvf mysql-5.5.2-m2.tar.gz
     4 cd mysql-5.5.2-m2/
     5 ./configure --prefix=/usr/local/mysql --enable-assembler --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
     6 make && make install
     7 chown -R mysql:mysql /usr/local/mysql
     8 /usr/local/mysql/bin/mysql_install_db --user=mysql
     9 cp support-files/my-huge.cnf /etc/my.cnf
    10 #vi /etc/my.cnf(优化mysql)
    11 /usr/local/mysql/bin/mysqld_safe --user=mysql &
    12 mysqladmin -uroot –p password 'password';
    13 delete from user where password=’’;
    14 cp /usr/local/mysql/share/mysql/mysql.server /etc/rc.d/init.d/mysqld
    15 chkconfig --add mysqld
    16 chkconfig --level 2345 mysqld on
    编译安装MySQL 5.5.2-m2

    3.编译安装PHP(FastCGI模式)

    1 tar zxvf php-5.2.13.tar.gz
    2 cd php-5.2.13/
    3 patch -p1 <../php-fpm-0.6~5.2.patch
    4 ./buildconf --force
    5 ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml  --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fpm --enable-fastcgi --with-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --enable-ftp --with-libevent=shared
    6 make ZEND_EXTRA_LIBS='-liconv'
    7 make install
    8 cp php.ini-dist /usr/local/php/etc/php.in
    编译安装PHP(FastCGI模式)

    注意上述命令中--enable-fpm的作用是开启php的fastcgi功能即开启php-fpm功能,--with-mysql=/usr/local/mysql是启用php支持mysql的功能,/usr/local/mysql是mysql数据库的安装路径。

    --enable-mbstring表示启用mbstring模块mbstring模块的主要作用在于检测和转换编码,提供对应的多字节操作的字符串函数。目前php内部的编码只支持ISO-8859-*、EUC-JP、UTF-8,其他的编码的语言是没办法在php程序上正确显示的,所以我们要启用mbstring模块。

    同时我们也只是简单的开启和扩展php的一部分功能,其他需要的功能,请自行添加。

    4.编译安装PHP5扩展模块

     1 tar zxvf memcache-2.2.5.tgz
     2 cd memcache-2.2.5/
     3 /usr/local/php/bin/phpize
     4 ./configure --with-php-config=/usr/local/php/bin/php-config
     5 make
     6 make install
     7 cd ../
     8 
     9 tar jxvf eaccelerator-0.9.6.tar.bz2
    10 cd eaccelerator-0.9.6/
    11 /usr/local/php/bin/phpize
    12 ./configure       --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
    13 make
    14 make install
    15 cd ../
    16 
    17 tar zxvf PDO_MYSQL-1.0.2.tgz
    18 cd PDO_MYSQL-1.0.2/
    19 /usr/local/php/bin/phpize
    20 ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
    21 make
    22 make install
    23 cd ../
    24 
    25 tar zxvf ImageMagick.tar.gz
    26 cd ImageMagick-6.5.1-2/
    27 ./configure
    28 make
    29 make install
    30 cd ../
    31 
    32 tar zxvf imagick-2.3.0.tgz
    33 cd imagick-2.3.0/
    34 /usr/local/php/bin/phpize
    35 ./configure --with-php-config=/usr/local/php/bin/php-config
    36 make
    37 make install
    38 cd ../
    编译安装PHP5扩展模块

    5.修改php.ini文件

    1 手工修改:查找/usr/local/php/etc/php.ini中的 extension_dir = "./"修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
    2 并在此行后增加以下几行,然后保存:
    • extension = "memcache.so"
    • extension = "pdo_mysql.so"
    • extension = "imagick.so"
    • 替换:
    • 1 sed -i "s/extension_dir = "./"/extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613"/g" /usr/local/php/etc/php.ini

     

    • 添加:
    • 1 sed -e "/extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613"/aextension = "memcache.so" extension = "pdo_mysql.so" extension = "imagick.so"" /usr/local/php/etc/php.ini
    • 再查找 output_buffering = Off
    • 修改为output_buffering = On
    •  1 sed -e 's/output_buffering = Off/output_buffering = on/g' /usr/local/php/etc/php.ini 

    配置eAccelerator加速PHP:

    •  1 mkdir -p /usr/local/eaccelerator_cache
    •  2 vi /usr/local/php/etc/php.ini 

    shift+g键跳到配置文件的最末尾,加上以下 配置信息:

     1 [eaccelerator]
     2 zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
     3 eaccelerator.shm_size="64"
     4 eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
     5 eaccelerator.enable="1"
     6 eaccelerator.optimizer="1"
     7 eaccelerator.check_mtime="1"
     8 eaccelerator.debug="0"
     9 eaccelerator.filter=""
    10 eaccelerator.shm_max="0"
    11 eaccelerator.shm_ttl="3600"
    12 eaccelerator.shm_prune_period="3600"
    13 eaccelerator.shm_only="0"
    14 eaccelerator.compress="1"
    15 eaccelerator.compress_level="9"

    6.创建www用户和组,以及供www.carl.com虚拟主机使用的目录:

    1 /usr/sbin/groupadd www
    2 /usr/sbin/useradd -g www www
    3 mkdir -p /data0/htdocs/blog
    4 chmod +w /data0/htdocs/blog
    5 chown -R www:www /data0/htdocs/blog

    7.创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php- cgi):

    1 在/usr/local/php/etc/目录中创建php-fpm.conf文件:
    2 rm -f /usr/local/php/etc/php-fpm.conf
    3 vi /usr/local/php/etc/php-fpm.conf
    1. 输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):
      1 <?xml version="1.0" ?>
      2 <configuration>
      3 
      4   All relative paths in this config are relative to php's install prefix

    php-fpm.conf

    8、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:

    1 ulimit -SHn 65535
    2 /usr/local/php/sbin/php-fpm start

    三、安装Nginx 0.8.34

    1、  安装Nginx所需的pcre库:

    1 tar zxvf pcre-8.01.tar.gz
    2 cd pcre-8.01/
    3 ./configure
    4 make && make install
    5 cd ../

    2、  安装Nginx

    1 tar zxvf nginx-0.8.34.tar.gz
    2 cd nginx-0.8.34/
    3 ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
    4 make && make install

    3、  创建Nginx配置文件

    96     access_log   off;
    97     }
    98   }
    99 }
    nginx.conf

    在/usr/local/nginx/conf/目录中创建fcgi.conf文件:

    vi /usr/local/nginx/conf/fcgi.conf

     1 fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
     2 fastcgi_param  SERVER_SOFTWARE    nginx;
     3 
     4 fastcgi_param  QUERY_STRING       $query_string;
     5 fastcgi_param  REQUEST_METHOD     $request_method;
     6 fastcgi_param  CONTENT_TYPE       $content_type;
     7 fastcgi_param  CONTENT_LENGTH     $content_length;
     8 
     9 fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
    10 fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
    11 fastcgi_param  REQUEST_URI        $request_uri;
    12 fastcgi_param  DOCUMENT_URI       $document_uri;
    13 fastcgi_param  DOCUMENT_ROOT      $document_root;
    14 fastcgi_param  SERVER_PROTOCOL    $server_protocol;
    15 
    16 fastcgi_param  REMOTE_ADDR        $remote_addr;
    17 fastcgi_param  REMOTE_PORT        $remote_port;
    18 fastcgi_param  SERVER_ADDR        $server_addr;
    19 fastcgi_param  SERVER_PORT        $server_port;
    20 fastcgi_param  SERVER_NAME        $server_name;
    21 
    22 # PHP only, required if PHP was built with --enable-force-cgi-redirect
    23 fastcgi_param  REDIRECT_STATUS    200;
    fcgi.conf

    4、  启动Nginx

    ulimit -SHn 65535
    /usr/local/nginx/sbin/nginx

    四、配置开机自动启动Nginx + PHP

                  vi /etc/rc.local

    1 ulimit -SHn 65535
    2 /usr/local/php/sbin/php-fpm start
    3 /usr/local/nginx/sbin/nginx

    五、优化Linux内核参数

    vi /etc/sysctl.conf

     1 net.ipv4.tcp_max_syn_backlog = 65536
     2 net.core.netdev_max_backlog =  32768
     3 net.core.somaxconn = 32768
     4 
     5 net.core.wmem_default = 8388608
     6 net.core.rmem_default = 8388608
     7 net.core.rmem_max = 16777216
     8 net.core.wmem_max = 16777216
     9 
    10 net.ipv4.tcp_timestamps = 0
    11 net.ipv4.tcp_synack_retries = 2
    12 net.ipv4.tcp_syn_retries = 2
    13 
    14 net.ipv4.tcp_tw_recycle = 1
    15 #net.ipv4.tcp_tw_len = 1
    16 net.ipv4.tcp_tw_reuse = 1
    17 
    18 net.ipv4.tcp_mem = 94500000 915000000 927000000
    19 net.ipv4.tcp_max_orphans = 3276800
    20 
    21 #net.ipv4.tcp_fin_timeout = 30
    22 #net.ipv4.tcp_keepalive_time = 120
    23 net.ipv4.ip_local_port_range = 1024  65535

     /sbin/sysctl –p 使新添加的内核参数生效!

    六、在不停止Nginx服务的情况下平滑变更Nginx配置
    1、修改/usr/local/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:

    /usr/local/nginx/sbin/nginx -t


                    如果屏幕显示以下两行信息,说明配置文件正确:
      the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
      the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

      2、平滑重启:
      ①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:

    /usr/local/nginx/sbin/nginx -s reload

    ②、对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号:

    ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'


      屏幕 显示的即为Nginx主进程号,例如:
      6302
       这时,执行以下命令即可使修改过的Nginx配置文件生效:

    kill -HUP 6302


      或者无需这么麻烦,找到Nginx的Pid文件:

    kill -HUP `cat /usr/local/nginx/nginx.pid`

    七、编写每天定时切割Nginx日志的脚本
      1、创建脚本/usr/local/nginx/sbin /cut_nginx_log.sh

    vi /usr/local/nginx/sbin/cut_nginx_log.sh


                    输入 以下内容:

    1 #!/bin/bash
    2 # This script run at 00:00
    3 
    4 # The Nginx logs path
    5 logs_path="/usr/local/nginx/logs/"
    6 
    7 mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
    8 mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
    9 kill -USR1 `cat /usr/local/nginx/nginx.pid`

    2、设置crontab,每天凌晨00:00切割nginx访问日志

    crontab -e

     输入以下内容:

    00 00 * * * /bin/bash  /usr/local/nginx/sbin/cut_nginx_log.sh
