2011年底爆发出来的hash dos漏洞威力十足, php-5.2.x和php-5.3.x 存在hash dos漏洞
所以这里面需要把 php-5.3.6 换成最新版, 详细查看这里
加强系统对支持字符编码转换的功能
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz tar zxvf libiconv-1.13.1.tar.gz cd libiconv-1.13.1/ ./configure --prefix=/usr/local make make install
加密算法库，PHP扩展mcrypt功能对此库有依耐关系
wget http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz 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
hash 加密算法库
wget http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz tar zxvf mhash-0.9.9.9.tar.gz cd mhash-0.9.9.9 ./configure make make install
ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2 ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4 ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8 ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2 ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
配置立即生效
ldconfig
wget http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz tar zxvf mcrypt-2.6.8.tar.gz cd mcrypt-2.6.8/ /sbin/ldconfig ./configure make make install
FastCGI模式
wget http://cn.php.net/get/php-5.3.6.tar.gz/from/this/mirror tar xvf php-5.3.6.tar.gz cd php-5.3.6 ./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/lib --with-freetype-dir=/usr/local/lib --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib --with-zlib \ --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-safe-mode --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 make ZEND_EXTRA_LIBS='-liconv' make install cp -f php.ini-production /usr/local/webserver/php/etc/php.ini cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm chmod u+x /etc/init.d/php-fpm
注：运行php-fpm前，记得先建立www用户，不然运行后会报错。因为PHP-FPM配置文件中是用www来运行的。
创建www用户和组
/usr/sbin/groupadd www /usr/sbin/useradd -g www www
编辑php-fpm.conf
cat > /usr/local/webserver/php/etc/php-fpm.conf <<'EOF' [global] pid = /usr/local/webserver/php/var/run/php-fpm.pid error_log = /usr/local/webserver/php/var/log/php-fpm.log log_level = notice emergency_restart_threshold = 10 emergency_restart_interval = 1m process_control_timeout = 5s daemonize = yes [www] listen = /tmp/php_fcgi.sock listen.backlog = -1 listen.allowed_clients = 127.0.0.1 user = www group = www listen.mode=0666 pm = static pm.max_children = 64 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 1024 request_terminate_timeout = 0s request_slowlog_timeout = 0s slowlog = logs/slow.log rlimit_files = 65535 rlimit_core = 0 chroot = chdir = catch_workers_output = yes env[HOSTNAME] = $HOSTNAME env[PATH] = /usr/local/bin:/usr/bin:/bin env[TMP] = /tmp env[TMPDIR] = /tmp env[TEMP] = /tmp php_flag[display_errors] = off EOF
启动前可先测试下php-fpm.conf的语法是否正确。
/usr/local/webserver/php/sbin/php-fpm -t
如出现下面的提示，表示没有问题。
[30 18:47:32] NOTICE: configuration file /usr/local/webserver/php/etc/php-fpm.conf test is successful
启动php-cgi进程后，监听的是127.0.0.1的9000端口，进程数为64(如果服务器内存小于3GB，可以只开启64个进程)，用户为www。
#/usr/local/webserver/php/sbin/php-fpm
设置开机启动
chkconfig -add php-fpm chkconfig php-fpm on
启动 php-fpm
service php-fpm start

After that the compilation works as a charm (NB: When writing this article, there where more recent versions of libmemcached but they couldn’t compile because CentOS 5 version of autoconf is too old. #vim clients/memcapable.cc #658 uint64_t value= 0xdeadbeefdeadcafeULL; #728 uint64_t value= 0xdeadbeefdeadcafeULL; #787 uint64_t value= 0xdeadbeefdeadcafeULL; ./configure –prefix=/usr/local/libmemcached make make installmemcached

| 选项 | 说明 |
|---|---|
| -d | 启动一个守护进程 |
| -m | 分配给Memcache使用的内存数量，单位是MB |
| -u | 运行Memcache的用户 |
| -l | 监听的服务器IP地址 |
| -p | Memcache监听的端口口 |
| -c | 最大运行的并发连接数，默认是1024 |
| -P | 设置保存Memcache的pid文件路径 |
可以启动多个守护进程，不过端口不能重复。
