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
 5 make install
 6 cd ../
 7 
 8 tar zxvf libmcrypt-2.5.8.tar.gz 
 9 cd libmcrypt-2.5.8/
10 ./configure
11 make
12 make install
13 /sbin/ldconfig
14 cd libltdl/
15 ./configure --enable-ltdl-install
16 make
17 make install
18 cd ../../
19 
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
35 ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
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\"/a\extension\ \=\ \"memcache.so\"\nextension\ \=\ \"pdo_mysql.so\"\nextension\ \=\ \"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

按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

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）：

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

rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf

输入以下内容：

 1 user  www www;
 2 
 3 worker_processes 8;

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
