CentOS 7下hhvm Nginx環境搭建，前面有介紹《CentOS 6下hhvm Nginx環境搭建》，到目前為止CentOS 7下還沒有hhvm rpm安裝包，因此采用源碼編譯。在安裝hhvm前強力建議先利用《lnmp一鍵安裝包》 安裝完整的
lnmp（包括Nginx、PHP、MySQL）,通過這種方式我們可以在同一台服務器對每個虛擬主機進行配置，如在同一台服務器上有 www.linuxeye.com跑在PHP上、另一個網站blog.linuxeye.com可以選擇跑在hhvm，並可以自由切換用php還是 hhvm，只需要簡單修改虛擬主機配置文件。
安裝步驟：
1. 安裝完整的LNMP，參考《lnmp一鍵安裝包》
2. 安裝hhvm
rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
yum -y install git mariadb-devel curl-devel expat-devel libpng-devel psmisc binutils-devel \

libxslt-devel libicu-devel tbb-devel libzip-devel bzip2-devel openldap-devel readline-devel \

cd lnmp/src
wget https://google-glog.googlecode.com/files/glog-0.3.3.tar.gz
tar xvzf glog-0.3.3.tar.gz
cd glog-0.3.3
./configure
make && make install
cd ..
wget http://www.geocities.jp/kosako3/oniguruma/archive/onig-5.9.5.tar.gz
tar xvzf onig-5.9.5.tar.gz
cd onig-5.9.5
./configure
make && make install
cd ..
git clone https://github.com/facebook/hhvm -b master hhvm --recursive
./configure
## use newer ImageMagick from remi
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
## remove the obsolete ImageMagick version
yum -y remove ImageMagick
yum -y install ImageMagick-last* --enablerepo=remi
cmake -D LIBMAGICKWAND_INCLUDE_DIRS="/usr/include/ImageMagick-6" \
-D LIBODBC_INCLUDE_DIRS="/usr/lib64" -D LIBODBC_LIBRARIES="/usr/lib64" \
-D LIBVPX_INCLUDE_DIRS="/usr/lib64" -D LIBXSLT_INCLUDE_DIR="/usr/lib64" \
-D LIBXSLT_LIBRARIES="/usr/lib64/libxslt.so" -D LIBMAGICKWAND_LIBRARIES="/usr/lib64/libMagickWand-6.Q16.so" \
-D LIBMAGICKCORE_LIBRARIES="/usr/lib64/libMagickCore-6.Q16.so" .
make -j2 #利用cpu多核編譯加快速度，2代表核數，單核不用加-j2
注：編譯過程非常消耗系統資源，有可能會報內存不夠導致編譯中斷，如下錯誤：
[ 30%] Building CXX object third-party/thrift/CMakeFiles/hphp_thrift.dir/thrift/lib/cpp/async/TEventTask.cpp.o
c++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate
編譯通過後，執行如下命令安裝：
make install
安裝成功後，打印出hhvm版本：
hhvm --version
HipHop VM 3.4.0-dev (rel)
Compiler: heads/master-0-g0b46339509ebd9612623d52c296fdcc8e6f93dff
Repo schema: d8dcfe0a4feda06dea7087bd82b55ef19217b170
Extension API: 20140829
3. 配置hhvm
創建並修改hhvm目錄權限
mkdir /var/run/hhvm /var/log/hhvm
chown -R www.www /var/run/hhvm /var/log/hhvm
修改/usr/local/nginx/conf/nginx.conf使其中一段成為如下：
location ~ .*\.(php|php5)?$ {
fastcgi_pass unix:/var/run/hhvm/sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
service nginx reload
下載支持hhvm方式添加虛擬主機腳本 vhost_hhvm.sh
cd lnmp
wget http://blog.linuxeye.com/wp-content/uploads/2014/05/vhost_hhvm.sh
chmod +x vhost_hhvm.sh
配置hhvm修改/etc/hhvm/config.hdf，保持如下：
ResourceLimit {
CoreFileSize = 0 # in bytes
MaxSocket = 10000 # must be not 0, otherwise HHVM will not start
SocketDefaultTimeout = 5 # in seconds
MaxRSS = 0
MaxRSSPollingCycle = 0 # in seconds, how often to check max memory
DropCacheCycle = 0 # in seconds, how often to drop disk cache
}
Log {
Level = Info
AlwaysLogUnhandledExceptions = true
RuntimeErrorReportingLevel = 8191
UseLogFile = true
UseSyslog = false
File = /var/log/hhvm/error.log
Access {
* {
File = /var/log/hhvm/access.log
Format = %h %l %u % t \"%r\" %>s %b
}
}
}
MySQL {
ReadOnly = false
ConnectTimeout = 1000 # in ms
ReadTimeout = 1000 # in ms
SlowQueryThreshold = 1000 # in ms, log slow queries as errors
KillOnTimeout = false
}
Mail {
SendmailPath = /usr/sbin/sendmail -t -i
ForceExtraParameters =
}
配置hhvm修改/etc/hhvm/server.ini，保持如下：
; php options
pid = /var/run/hhvm/pid
; hhvm specific
;hhvm.server.port = 9001
hhvm.server.file_socket = /var/run/hhvm/sock
hhvm.server.type = fastcgi
hhvm.server.default_document = index.php
hhvm.log.use_log_file = true
hhvm.log.file = /var/log/hhvm/error.log
hhvm.repo.central.path = /var/run/hhvm/hhvm.hhbc
修改/etc/hhvm/php.ini指定mysql.sock路徑（hhvm默認路徑sock路徑是/var/lib/mysql/mysql.sock）
hhvm.mysql.socket = /tmp/mysql.sock
expose_php = 0 ;關閉頭信息X-Powered-By (和hhvm.server.expose_hphp = false作用一樣)
memory_limit = 400M
post_max_size = 50M
添加開機自啟動腳本
保證文件/etc/systemd/system/hhvm.service內容如下：
[Unit]
Description=HHVM HipHop Virtual Machine (FCGI)
[Service]
ExecStart=/usr/local/bin/hhvm --mode daemon --user www --config /etc/hhvm/server.ini \
--config /etc/hhvm/php.ini --config /etc/hhvm/config.hdf
[Install]
WantedBy=multi-user.target
管理hhvm服務
systemctl enable hhvm #開機自啟動
systemctl start hhvm #啟動hhvm
systemctl status hhvm #查看hhvm狀態
