FastCGI (PHP)

First, what is fastcgifastcgi is a scalable, high-speed communication interface between Http server and the dynamic scripting language. Most http server support fastcgi, such as:nginx  AAPACHE&NBSP;LIGHTTPD, etc... FASTCGI is supported by many languages. There is PHP. Second, nginx+fastcgi operation principle (1) Nginx does not support the direct invocation or parsing of external programs, all outsourced programs (including PHP) must be called through FASTCGI (2) fastcgi interface under Linux can ( Socket file way exists, then can IP), (3) in order to invoke the CGI program, also need a fastcgi wrapper, when Nginx send CGI request to this socket. The request is wrapper through the FastCGI interface, and then a new thread is derived, which invokes the external program or the script reads but returns the data .    finally wrapper the data returned through the FastCGI interface. Passing the fixed socket to Nginx, and finally returning to the data sent by the client .   nginx--> send a CGI request-->fastcgi (Warpper) received this request---> Derive a new thread---> Call an external program or script to return data--->wrapper to pass the data along a fixed socket to the nginx--> by Nginx to return this data to the user. Iii. installation and optimization of PHP and PHP-FPM &NBSP;&NBSP;&NBSP;PHP-FPM is also a third-party fastcgi process Management, which is developed as a PHP patch and compiled together into the PHP kernel when it is written. PHP-FPM is very good at dealing with high concurrency. It's a bit: it is to separate the dynamic language and the Http server (static and static separation), Http server mainly deal with quiescent requests, PHP-FPM processing dynamic requests.     all  PHP/PHP-FPM  and nginx are often assembled onto a single machine to meet business requirements .     Four, first install MySQL ( 1) First install MySQL database, PHP at compile time need a configuration of MySQL so php remote link mysql only use # cd /data/soft/# tar xf mysql-5.1.49.tar.gz -c tmp/# cd tmp/ mysql-5.1.49/#CONFOPTS = " --with-charset=utf8 --with-plugins=partition,federated,innobase,myisam  --enable-static --enable-assembler --enable-thread-safe-client --with-client-ldflags=- All-static-ltinfo --with-mysqld-ldflags=-all-static-ltinfo --with-big-tables --with-mysqld-user =mysql --without-debug --without-ndb-debug --localstatedir=/usr/local/services/mysql-5.1.49/var  --prefix=/usr/local/services/mysql-5.1.49  "#./configure  $CONFOPTS  >/dev/null#  make >/dev/null && make install >/dev/null  Five, Install PHP dependent libraries ①libxml2-2.7.7.tar.gz# cd /data/soft/#tar  xf libxml2-2.7.7.tar.gz –C  Tmp/# cd tmp/libxml2-2.7.7/#./configure --prefix=/usr/local/services >/dev/null#make  >/dev/null && make install >/dev/null②curl-7.21.4.tar.gz# cd /data/soft/# tar xf  curl-7.21.4.tar.gz -c tmp/# cd tmp/curl-7.21.4/#./configure --prefix=/usr/local/ services >/dev/null#make >/dev/null && make install >/dev/ null③jpegsrc.v8b.tar.gz# cd /data/soft/#tar  xf jpegsrc.v8b.tar.gz –c tmp/#cd  tmp/jpeg-8b/#./configure --prefix=/usr/local/services >/dev/null#make >/dev/null  && make install >/dev/null④libpng-1.4.3.tar.gz# cd /data/soft/#  tar xf libpng-1.4.3.tar.gz -C tmp/# cd tmp/libpng-1.4.3/#./configure  --prefix=/usr/local/services >/dev/null#make >/dev/null && make install  >/dev/null⑤freetype-2.4.1.tar.gz# cd /data/soft/# tar xf  freetype-2.4.1.tar.gz -c tmp/# cd tmp/freetype-2.4.1/#./configure --prefix=/usr/local/services >/dev/null#make >/dev/null & & make install >/dev/null⑥libevent-2.0.10-stable.tar.gz# cd /data/soft/#  tar xf libevent-2.0.10-stable.tar.gz –c tmp/# cd tmp/libevent-2.0.10-stable/#./ configure --prefix=/usr/local/services --disable-debug-mode >/dev/null#make >/dev/ null && make install >/dev/null⑦re2c-0.13.5.tar.gz# cd /data/soft/#  tar xf re2c-0.13.5.tar.gz -c tmp/# cd tmp/re2c-0.13.5/#./configure -- Prefix=/usr/local/services >/dev/null#make >/dev/null && make install  >/dev/null⑧libmcrypt-2.5.8.tar.gz# cd /data/soft/# tar xf  libmcrypt-2.5.8.tar.bz2 -c tmp/# cd tmp/libmcrypt-2.5.8/#./configure --prefix=/usr/ Local/services >/dev/null#make >/dev/null && make install >/dev/null# cd libltdl/# ./ configure --prefix=/usr/local/services --enable-ltdl-install >/dev/null#make >/dev/ Null && make install >/dev/null VI, install PHP dependent library wget http://php.net/ distributions/php-5.3.13.tar.gzphp-5.3.13.tar.gz# cd /data/soft/# tar xf  php-5.3.13.tar.gz -c tmp/#cd  tmp/php-5.3.13/#CONFOPTS = "--enable-zend-multibyte -- Enable-mbstring --enable-sockets --enable-pdo --enable-zip --enable-fpm --with-gd  --with-fpm-user=user_00 --with-fpm-group=user_00 --with-zlib --with-config-file-path=/usr /local/services/php-5.3.13/etc --with-libxml-dir=/usr/local/services --with-curl=/usr/local/services  --with-png-dir=/usr/local/services --with-jpeg-dir=/usr/local/services --with-freetype-dir=/ Usr/local/services --with-mysql=/usr/local/services/mysql --with-pdo-mysql=/usr/local/services/mysql --with-mysqli=/usr/local/services/mysql/bin/ mysql_config --prefix=/usr/local/services/php-5.3.13  "# ./configure  $CONFOPTS # make  >/dev/null && make install >/dev/null compilation Error Resolution:/var/lib/mysql/ Mysql.sockconfigure: error: cannot find libmysqlclient under /usr. note that the mysql client library is not bundled anymore!
