php5.3.10的安装
下面以最新的php-5.3.10为例进行安装。
wget http://cn.php.net/distributions/php-5.3.10.tar.gz
tar -zxvf php-5.3.10.tar.gz
cd php-5.3.10
./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 –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir –enable-xml –disable-rpath –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fpm –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-tidy –enable-json
上面的具体参数可以使用./configure –help查看
make ZEND_EXTRA_LIBS=’-liconv’
make test
make && make install （此处最好分开做，因为make的时候会有报错出现。）
我在上面的make时就报了下面的错误
root/source/php-5.3.10/sapi/cli/php: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
make: *** [ext/phar/phar.php] Error 127
解决办法是（我的mysql安装目录是/usr/local/msyql，这个视自己的mysql安装路径而定。）
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/
64位系统应使用下面的这行
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/
cp php.ini-production /usr/local/php/etc/php.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
cp sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf
修改php.ini文件和php-fpm文件中参数，可以手动更改也可以用下面的sed命令更改
sed -i ‘s#short_open_tag = Off#short_open_tag = On#g’ /usr/local/php/etc/php.ini
sed -i ‘s#;pid = run/php-fpm.pid#pid = run/php-fpm.pid#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.max_children = 5#pm.max_children = 32#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.start_servers = 2#pm.start_servers = 16#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.min_spare_servers = 1#pm.min_spare_servers = 8#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.max_spare_servers = 3#pm.max_spare_servers = 32#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#;pm.max_requests = 500#pm.max_requests = 120#g’ /usr/local/php/etc/php-fpm.conf
关于php-fpm几个重要参数的调整方面具体可以参看我的另一篇日志：http://www.361way.com/php-fpm/890.html 另外php官方也给出了其中所有参数项的解释说明，具体见http://www.php.net/manual/en/install.fpm.configuration.php
设置开机启动
chmod 755 /etc/init.d/php-fpm
chkconfig –add php-fpm
/etc/init.d/php-fpm start
至此，php的安装完毕。
最后可以再安装一些php的扩展包和开户php加速（具体软件包可以视网上的最新版进行安装）：
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/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/bin/phpize
./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../
tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config –with-pdo-mysql=/usr/local/mysql
make
make install
cd ../
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../
tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../
修改php.ini文件
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/”
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”
再查找output_buffering = Off
修改为output_buffering = On
再查找; cgi.fix_pathinfo=0
修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。
配置eAccelerator加速PHP：
mkdir -p /opt/webserver/eaccelerator_cache
vi /usr/local/php/etc/php.ini
在php.ini配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension=”/usr/local/php/lib/php/extensions/eaccelerator.so”
eaccelerator.shm_size=”64″
eaccelerator.cache_dir=”/opt/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=”3600″
eaccelerator.shm_prune_period=”3600″
eaccelerator.shm_only=”0″
eaccelerator.compress=”1″
eaccelerator.compress_level=”9″
php的安全性设置：
找到：;open_basedir =
修改为：open_basedir = .:/tmp/ #防止php木马跨站，重要！！
找到：disable_functions =
修改为：disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname
#列出PHP可以禁用的函数，如果某些程序需要用到这个函数，可以删除，取消禁用。
找到：;date.timezone =
修改为：date.timezone = PRC
找到：expose_php = On
修改为：expose_php = OFF #禁止显示php版本的信息
找到：display_errors = On
修改为：display_errors = OFF #关闭错误提示
