背景：HipHop是Facebook在今年早些時(shí)候放出的一個(gè)php開源項(xiàng)目，主要的特征就是把php翻譯成了c++執(zhí)行，HipHop所帶來(lái)的性能提升用Facebook官方博客上項(xiàng)目負(fù)責(zé)人趙海平的話說(shuō)：
With HipHop we’ve reduced the CPU usage on our Web servers on average by about fifty percent, depending on the page. Less CPU means fewer servers, which means less overhead. This project has had a tremendous impact on Facebook.
HipHop的官網(wǎng)是http://github.com/facebook/hiphop-php，上面有說(shuō)明了HipHop的安裝步驟，但是我個(gè)人感覺那還是不夠詳細(xì)具體的，實(shí)際的安裝過(guò)程中會(huì)碰到了不少問(wèn)題。
在此我詳細(xì)羅列出安裝步驟和分享出解決所碰到問(wèn)題的過(guò)程和方法，以便能幫助到那些喜愛php技術(shù)，想要了解HipHop的人，能對(duì)HipHop有更深層次的認(rèn)識(shí)。
我的環(huán)境準(zhǔn)備： Centos 5.5 64bit，Corei7 860，4G內(nèi)存（注意：內(nèi)存不能太小，HipHop在make時(shí)候和運(yùn)行時(shí)候是很耗內(nèi)存的；操作系統(tǒng)最好為64位）
開始安裝：
1.切換到root賬號(hào)并建立/root/bulid目錄
[user@localhost ~]$ su -
[root@localhost ~]# mkdir build
[root@localhost ~]# cd build
2.安裝rpmforge
[root@localhost build]# yum install yum-priorities
[root@localhost build]# wget http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
[root@localhost build]# rpm -import http://apt.sw.be/RPM-GPG-KEY.dag.txt
[root@localhost build]# rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
[root@localhost build]# rpm -i rpmforge-release-0.3.6-1.el5.rf.*.rpm
[root@localhost build]# yum check-update
[root@localhost build]# vim /etc/yum.repos.d/rpmforge.repo 修改enabled = 0
3.直接先用yum安裝一些HipHop需要的基礎(chǔ)包
[root@localhost build]# yum install \
binutils \
binutils-devel \
bison \
cmake \
curl-devel \
distcc \
expat \
gcc \
gcc-c++ \
gd \
gd-devel \
git \
libcap-devel \
libevent-devel \
libmcrypt-devel \
libssh2 \
libxml2-devel \
openssl-devel \
pcre-devel \
re2c \
flex \
zlib \
--enablerepo=rpmforge
4.安裝perl git
[root@localhost build]# wget http://www.kernel.org/pub/software/scm/git/RPMS/x86_64/perl-Git-1.5.6.1-1.x86_64.rpm
[root@localhost build]# rpm -U perl-Git-1.5.6.1-1.x86_64.rpm
5.安裝tbb
[root@localhost build]# wget http://www.threadingbuildingblocks.org/uploads/77/151/3.0/tbb30_20100406oss_lin.tgz
[root@localhost build]# tar xvzf tbb30_20100406oss_lin.tgz
[root@localhost build]# export TBB_INSTALL_DIR="/root/build/tbb30_20100406oss"
[root@localhost build]# export TBB_ARCH_PLATFORM="intel64/cc4.1.0_libc2.4_kernel2.6.16.21"
注意：我一開始cmake的時(shí)候，總會(huì)報(bào)Could NOT find TBB library的錯(cuò)誤，分析了hiphop-php/CMake/FindTBB.cmake源碼后，發(fā)現(xiàn)167行為：
set (TBB_LIBRARY_DIR "${_TBB_INSTALL_DIR}/$ENV{TBB_ARCH_PLATFORM}/lib")
改為
set (TBB_LIBRARY_DIR "${_TBB_INSTALL_DIR}/lib/$ENV{TBB_ARCH_PLATFORM}")
后即可。
因此我得出一個(gè)結(jié)論，當(dāng)你配置好了環(huán)境變量而cmake的時(shí)候又提示你找不到這個(gè)lib的時(shí)候，本身的cmake文件和你下載下來(lái)的的lib不匹配就可能導(dǎo)致此問(wèn)題，解決的辦法即是直接修改cmake文件，滿足符合你的需要。
當(dāng)然還會(huì)有其他可能導(dǎo)致類似的問(wèn)題，我接下去會(huì)說(shuō)。
6.通過(guò)rpm包安裝boost和icu庫(kù)

cmake一般出錯(cuò)就是提示庫(kù)找不到，原因出了之前說(shuō)的那種外還有可能是程序找的/usr/lib/libxxx.so，而這個(gè)lib本身叫/usr/lib/libxxx.so.1，因此你需要cp一份或是ln，讓程序能找得到。
14.make HipHop,離勝利僅僅一步之遙了！
[root@localhost hiphop-php]# make
make的時(shí)候很耗cpu和內(nèi)存的，因此想在vps上玩HipHop的同學(xué)要注意了，有可能程序會(huì)卡死。
我在make的過(guò)程中碰到如下的錯(cuò)誤：
追到ext_mysql.cpp的722行后看到有如下語(yǔ)句：
721 static Variant php_mysql_localize_result(MYSQL *mysql) {
722 mysql = mysql->last_used_con;
723 if (!mysql->fields) return true;
724 if (mysql->status != MYSQL_STATUS_GET_RESULT) {
725 // consistent with php_mysql_do_query_general
726 return true;
727 }
我查詢了mysql-5.5.3的源碼后，發(fā)現(xiàn)MYSQL的定義并沒(méi)有l(wèi)ast_used_con，結(jié)構(gòu)如下：
typedef struct st_mysql
{
NET net; /* Communication parameters */
unsigned char *connector_fd; /* ConnectorFd for SSL */
char *host,*user,*passwd,*unix_socket,*server_version,*host_info;
char *info, *db;
struct charset_info_st *charset;
MYSQL_FIELD *fields;
MEM_ROOT field_alloc;
my_ulonglong affected_rows;
my_ulonglong insert_id; /* id if insert on table with NEXTNR */
my_ulonglong extra_info; /* Not used */
unsigned long thread_id; /* Id for connection in server */
unsigned long packet_length;
unsigned int port;
unsigned long client_flag,server_capabilities;
unsigned int protocol_version;
unsigned int field_count;
unsigned int server_status;
unsigned int server_language;
unsigned int warning_count;
struct st_mysql_options options;
enum mysql_status status;
my_bool free_me; /* If free in mysql_close */
my_bool reconnect; /* set to 1 if automatic reconnect */
/* session-wide random string */
char scramble[SCRAMBLE_LENGTH+1];
my_bool unused1;
void *unused2, *unused3, *unused4, *unused5;
LIST *stmts; /* list of all statements */
const struct st_mysql_methods *methods;
void *thd;
/*
Points to boolean flag in MYSQL_RES or MYSQL_STMT. We set this flag
from mysql_stmt_close if close had to cancel result set of this object.
*/
my_bool *unbuffered_fetch_owner;
/* needed for embedded server - no net buffer to store the 'info' */
char *info_buffer;
void *extension;
} MYSQL;
然后我google追了下mysql之前的源碼，是有過(guò)存在last_used_con的時(shí)期，但是后來(lái)已經(jīng)被mysql的開發(fā)人員廢棄了，因此我 懷疑這個(gè)有可能是HipHop在開發(fā)的時(shí)候MYSQL的結(jié)構(gòu)里還有l(wèi)ast_used_con，但是我下載的mysql庫(kù)已經(jīng)沒(méi)有，所以導(dǎo)致此問(wèn)題。
我把722的mysql = mysql->last_used_con;刪除后重新make就沒(méi)有問(wèn)題了。
還有一點(diǎn)需要注意的是：如果是你在cmake階段出現(xiàn)的問(wèn)題，但是在make階段暴露了，你需要重新cmake的時(shí)候你需要移除hiphop-php/CMakeCache.txt文件。
到此，HipHop的安裝就算告一段落，還是比較繁瑣的，希望以后facebook能簡(jiǎn)化這個(gè)過(guò)程。
未來(lái)的文章里我會(huì)對(duì)HipHop的應(yīng)用有持續(xù)的說(shuō)明，比如它如何編譯smarty，以及各種環(huán)境性能的測(cè)試比較，盡請(qǐng)期待！
