PHP5安装、配置内容

[复制链接]
发表于 2010-9-16 09:08:18 | 显示全部楼层 |阅读模式
二、安装PHP 5.2.6(FastCGI模式)
  1、编译安装PHP 5.2.6所需的支持库:
  tar zxvf libiconv-1.12.tar.gz
  cd libiconv-1.12/
  ./configure --prefix=/usr/local
  make
  make install
  cd ../  tar zxvf libmcrypt-2.5.8.tar.gz
  cd libmcrypt-2.5.8/
  ./configure
  make
  make install
  /sbin/ldconfig
  cd libltdl/
  ./configure --enable-ltdl-install
  make
  make install
  cd ../../  tar zxvf mhash-0.9.9.tar.gz
  cd mhash-0.9.9/
  ./configure
  make
  make install
  cd ../  cp /usr/local/lib/libmcrypt.* /usr/lib
  ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2  tar zxvf mcrypt-2.6.7.tar.gz
  cd mcrypt-2.6.7/
  ./configure
  make
  make install
  cd ../   2、编译安装MySQL 5.1.26-rc
  /usr/sbin/groupadd mysql
  /usr/sbin/useradd -g mysql mysql
  tar zxvf mysql-5.1.26-rc.tar.gz
  cd mysql-5.1.26-rc/
  ./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile
  make && make install
  chmod +w /usr/local/webserver/mysql
  chown -R mysql:mysql /usr/local/webserver/mysql
  cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf
  cd ../   附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下两步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。
  ①、以mysql用户帐号的身份建立数据表:
  /usr/local/webserver/mysql/bin/mysql_install_db --defaults-file=/usr/local/webserver/mysql/my.cnf --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql --pid-file=/usr/local/webserver/mysql/mysql.pid --skip-locking --port=3306 --socket=/tmp/mysql.sock
  ②、启动MySQL(最后的&表示在后台运行)
  /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &   3、编译安装PHP(FastCGI模式)
  tar zxvf php-5.2.6.tar.gz
  gzip -cd php-5.2.6-fpm-0.5.8.diff.gz | patch -d php-5.2.6 -p1
  cd php-5.2.6/
  ./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/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 --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl
  sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile
  make
  make install
  cp php.ini-dist /usr/local/webserver/php/etc/php.ini
  cd ../   4、编译安装PHP5扩展模块
  tar zxvf memcache-2.2.3.tgz
  cd memcache-2.2.3/
  /usr/local/webserver/php/bin/phpize
  ./configure --with-php-config=/usr/local/webserver/php/bin/php-config
  make
  make install
  cd ../  tar jxvf eaccelerator-0.9.5.3.tar.bz2
  cd eaccelerator-0.9.5.3/
  /usr/local/webserver/php/bin/phpize
  ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config
  make
  make install
  cd ../
  5、修改php.ini文件
  手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
  修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
  并在此行后增加以下几行,然后保存:
  extension = "memcache.so"  再查找output_buffering = Off
  修改为output_buffering = On  自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
  sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\n#' /usr/local/webserver/php/etc/php.ini
  sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini
  6、配置eAccelerator加速PHP:
  mkdir -p /usr/local/webserver/eaccelerator_cache
  vi /usr/local/webserver/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:
  引用
  [eaccelerator]
  zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
  eaccelerator.shm_size="128"
  eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"
  eaccelerator.enable="1"
  eaccelerator.optimizer="1"
  eaccelerator.check_mtime="1"
  eaccelerator.debug="0"
  eaccelerator.filter=""
  eaccelerator.shm_max="0"
  eaccelerator.shm_ttl="300"
  eaccelerator.shm_prune_period="120"
  eaccelerator.shm_only="0"
  eaccelerator.compress="1"
  eaccelerator.compress_level="9"
  修改配置文件:
  vi /etc/sysctl.conf  输入以下内容:
  引用
  kernel.shmmax = 134217728  然后执行以下命令使配置生效:
  /sbin/sysctl -p   7、创建www用户和组,以及供blog.s135.com和www.s135.com两个虚拟主机使用的目录:
  /usr/sbin/groupadd www -g 48
  /usr/sbin/useradd -u 48 -g www www
  mkdir -p /data0/htdocs/blog
  chmod +w /data0/htdocs/blog
  chown -R www:www /data0/htdocs/blog
  mkdir -p /data0/htdocs/www
  chmod +w /data0/htdocs/www
  chown -R www:www /data0/htdocs/www
  8、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):
  在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件:
  rm -f /usr/local/webserver/php/etc/php-fpm.conf
  vi /usr/local/webserver/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):

     9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为200(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
  ulimit -SHn 51200
  /usr/local/webserver/php/sbin/php-fpm start  注:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。
