由于某些程序不支持php5.2以上的版本,需要安装低版本的PHP和Zend。公司的系统为阿里云的CentOS 6.5 64位版,不能使用yum安装,只能编译安装。我装的是php5.2.17,同时装上了ZendOptimizer3.3.9。安装过程中需要用到的软件在文章末尾,大家自行下载即可。下面就来看下具体步骤:
第一步:安装系统环境需要的软件
yum install -y gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-libs krb5-devel krb5-server libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
第二步:编译安装PHP-5.2.17所需要的库
tar zxvf libiconv-1.13.1.tar.gz cd libiconv-1.13.1 ./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 jxvf mhash-0.9.9.9.tar.bz2 cd mhash-0.9.9.9 ./configure make && make install echo "/usr/local/lib" >>/etc/ld.so.conf /sbin/ldconfig cd tar zxvf mcrypt-2.6.8.tar.gz cd mcrypt-2.6.8 /sbin/ldconfig ./configure make && make install
注:这里用到的软件都已经下载放到了root里面,下同。
第三步:编译安装PHP-5.2.17(FastCGI)
mkdir -p /usr/rocal/php-5.2.17 tar zxvf php-5.2.17.tar.gz gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1 cd php-5.2.17 patch -p1 < ../php-5.2.17-max-input-vars.patch sed -i "s/\!png_check_sig (sig, 8)/png_sig_cmp (sig, 0, 8)/" ext/gd/libgd/gd_png.c cd php-5.2.17 ln -s /usr/lib64/libjpeg.so /usr/lib/libjpeg.so ln -s /usr/lib64/libpng.so /usr/lib/libpng.so cp -frp /usr/lib64/libldap* /usr/lib/ ./configure --prefix=/usr/local/php-5.2.17 --with-config-file-path=/usr/local/php-5.2.17/etc --with-mysql=/var/lib/mysql --with-mysqli=/usr/lib64/mysql/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 --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap make ZEND_EXTRA_LIBS='-liconv' make install cp php.ini-dist /usr/local/php-5.2.17/etc/php.ini cd
第四步:编译安装PHP5扩展模块
tar zxvf memcache-2.2.6.tgz cd memcache-2.2.6/ /usr/local/php-5.2.17/bin/phpize ./configure --with-php-config=/usr/local/php-5.2.17/bin/php-config make && make install cd tar jxvf eaccelerator-0.9.6.1.tar.bz2 cd eaccelerator-0.9.6.1/ /usr/local/php-5.2.17/bin/phpize ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php-5.2.17/bin/php-config --without-eaccelerator-use-inode make && make install cd tar zxvf PDO_MYSQL-1.0.2.tgz cd PDO_MYSQL-1.0.2 /usr/local/php-5.2.17/bin/phpize ./configure --with-php-config=/usr/local/php-5.2.17/bin/php-config --with-pdo-mysql=/var/lib/mysql make && make install cd tar zxvf ImageMagick-6.7.0-8.tar.gz cd ImageMagick-6.7.0-8 ./configure make && make install cd tar zxvf imagick-3.0.1.tgz cd imagick-3.0.1 /usr/local/php-5.2.17/bin/phpize ./configure --with-php-config=/usr/local/php-5.2.17/bin/php-config make && make install cd
第五步:修改php.ini文件
sed -i "s/output_buffering = Off/output_buffering = On/" /usr/local/php-5.2.17/etc/php.ini sed -i "s/extension_dir =/; extension_dir =/" /usr/local/php-5.2.17/etc/php.ini sed -i "s/; cgi.fix_pathinfo=0/cgi.fix_pathinfo=0/" /usr/local/php-5.2.17/etc/php.ini sed -i 's%;open_basedir =%open_basedir ="/tmp/:/data/www/"%' /usr/local/php-5.2.17/etc/php.ini sed -i "s/disable_functions =/disable_functions = popen,pentl_exec,passthru,exec,system,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,show_source,escapeshellcmd,escapeshellarg,curl_exec,curl_multi_exec,parse_ini_file,assert/" /usr/local/php-5.2.17/etc/php.ini sed -i "s/expose_php = On/expose_php = Off/" /usr/local/php-5.2.17/etc/php.ini sed -i "s/display_errors = On/display_errors = Off/" /usr/local/php-5.2.17/etc/php.ini sed -i "s/log_errors = Off/log_errors = On/" /usr/local/php-5.2.17/etc/php.ini
第六步:创建并配置php-fpm.conf文件
vim /usr/local/php-5.2.17/php-fpm.conf
配置如下:
<?xml version="1.0" ?> <configuration> All relative paths in this config are relative to php's install prefix <section name="global_options"> Pid file <value name="pid_file">/usr/local/php-5.2.17/logs/php-fpm.pid</value> Error log file <value name="error_log">/usr/local/php-5.2.17/logs/php-fpm.log</value> Log level <value name="log_level">notice</value> When this amount of php processes exited with SIGSEGV or SIGBUS ... <value name="emergency_restart_threshold">10</value> ... in a less than this interval of time, a graceful restart will be initiated.

Used in logs and stats. <value name="name">default</value> Address to accept fastcgi requests on. Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket' <value name="listen_address">127.0.0.1:9000</value> <value name="listen_options"> Set listen(2) backlog <value name="backlog">-1</value> Set permissions for unix socket, if one used.

Many BSD-derrived systems allow connections regardless of permissions. <value name="owner"></value> <value name="group"></value> <value name="mode">0666</value> </value> Additional php.ini defines, specific to this pool of workers. <value name="php_defines"> <value name="sendmail_path">/usr/sbin/sendmail -t -i</value> <value name="display_errors">1</value> </value> Unix user of processes <value name="user">www</value> Unix group of processes <value name="group">www</value> Process manager settings <value name="pm"> Sets style of controling worker process count. Valid values are 'static' and 'apache-like' <value name="style">static</value> Sets the limit on the number of simultaneous requests that will be served. Equivalent to Apache MaxClients directive. Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi Used with any pm_style. <value name="max_children">8</value> Settings group for 'apache-like' pm style <value name="apache_like"> Sets the number of server processes created on startup.

If not set, they will be redirected to /dev/null, according to FastCGI specs <value name="catch_workers_output">yes</value> How much requests each process should execute before respawn. Useful to work around memory leaks in 3rd party libraries. For endless request processing please specify 0 Equivalent to PHP_FCGI_MAX_REQUESTS <value name="max_requests">1024</value> Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect. Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+) Makes sense only with AF_INET listening socket. <value name="allowed_clients">127.0.0.1</value> Pass environment variables like LD_LIBRARY_PATH <value name="environment"> <value name="PATH">/usr/local/bin:/usr/bin:/bin</value> <value name="TMP">/tmp</value> <value name="TMPDIR">/tmp</value> <value name="TEMP">/tmp</value> <value name="OSTYPE">$OSTYPE</value> <value name="MACHTYPE">$MACHTYPE</value> <value name="MALLOC_CHECK_">2</value> </value> </section> </workers> </configuration>
创建www用户及启动php-fpm并加入启动脚本
/usr/sbin/groupadd www /usr/sbin/useradd -g www www mkdir -p /var/www chown -R www:www /var/www/html chmod +w /var/www/html ulimit -SHn 65535 /usr/local/php-5.2.17/sbin/php-fpm start echo "ulimit -SHn 65535" >> /etc/rc.local echo "/usr/local/php-5.2.17/sbin/php-fpm start" >> /etc/rc.local
注:这里的/var/www/html是我网站的目录,你们可以根据自己的情况修改。
第七步:安装ZendOptimizer 3.3.9
解压ZendOptimizer 3.3.9,并复制ZendOptimizer.so到/usr/local/Zend/lib/
tar -zxvf ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz cd ZendOptimizer-3.3.9-linux-glibc23-x86_64 cd data/5_2_x_comp mkdir -p /usr/local/Zend/lib cp ZendOptimizer.so /usr/local/Zend/lib/ cd data/5_2_x_comp/ mkdir -p /usr/local/Zend/lib cp ZendOptimizer.so /usr/local/Zend/lib/
注:/usr/local/Zend/lib/这个目录可以自定义。
在/usr/local/php-5.2.17/etc/php.ini文件尾部添加
[Zend] zend_optimizer.optimization_level=1023 zend_optimizer.encoder_loader=1 zend_extension=/usr/local/Zend/lib/ZendOptimizer.so
第八步:安装完成
重新启动PHP-5.2.17和Nginx,并查看安装结果
/usr/local/php-5.2.17/sbin/php-fpm restart service nginx restart /usr/local/php-5.2.17/bin/php -v
结果如下:
