如今Intel 自家的編譯器已經發展到了第12個發行版，對於兼容性來說達到了極大的提高，以往版本無法編譯的程序現在大部分都可以編譯通過了，那麼現在，已經到了介紹如何使用ICC 的時機咯。（採用ICC 編譯的程序運行效率普遍比GCC 高10%～300%）當然拉，我們還是只介紹64 位Linux OS 的安裝方式，32位的朋友請先RIOS
Step 1：確保你的服務器安裝的是Intel 芯片
Step 2：安裝JDK
mkdir /software
cd software
wget http://download.oracle.com/otn-pub/java/jdk/6u26-b03/jdk-6u26-linux-x64.bin
chmod 777 jdk-6u26-linux-x64.bin
./ jdk-6u26-linux-x64.bin
請按照提示一路往下yes, 最終生成jdk 文件夾
mv jdk-($version) /usr/local/jdk
修改環境變量
nano /etc/profile
在最下方插入
export JAVA_HOME=/usr/local/jdk
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
重啟服務器
reboot
檢測JDK 是否安裝成功
java -version
Step 3：安裝ICC
首先更新需要支持的軟件包
apt-get install gcc g++ libstdc++6
下載並安裝ICC 12
cd /software
wget http://registrationcenter-download.intel.com/akdlm/irc_nas/2136/l_ccompxe_intel64_2011.4.191.tgz
tar zxf l_ccompxe_intel64_2011.4.191.tgz
cd l_ccompxe_intel64_2011.4.191
./install.sh
一路往下，遇到輸入序列號部分請輸入N49V-RFT67VK7 注意這是非商用版本，安裝成功後需要首先開啟編譯器系統集成
source /opt/intel/composerxe-2011.4.191/bin/iccvars.sh intel64
至此ICC 安裝成功，檢測一下，如遇到文本中未指出錯誤，請開動腦筋Google
icc -v
Step 4：安裝PHP NGINX 支持軟件包，以下軟件包若不偷懶也可採用ICC 編譯
apt-get install autoconf libfreetype6-dev libxml2-dev zlib1g-dev linux-libc-dev libglib2.0-dev bzip2 libbz2-dev libncurses5-dev curl libcurl4-openssl-dev e2fsprogs libkrb5-dev libidn11-dev openssl libssl-dev make libsasl2 -dev libperl-dev libgeoip-dev

; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;
; Multiple pools of child processes may be started with different listening

; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway:)
; Start a new pool named ‘www’.
; the variable $pool can we used in any directive and will be replaced by the
; pool name (‘www’ here)
[default]
; Per pool prefix
; It only applies on the following directives:
; – ‘slowlog’
; – ‘listen’ (unixsocket)
; – ‘chroot’
; – ‘chdir’
; – ‘php_values’
; – ‘php_admin_values’
; When not set , the global prefix (or /usr/local/webserver/php) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; ‘ip.add.re.ss:port’ – to listen on a TCP socket to a specific address on
; a specific port;
; ‘port’ – to listen on a TCP socket to all addresses on a
; specific port;
; ‘/path/to/unix/socket’ – to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000
; Set listen(2) backlog. A value of ‘-1’ means unlimited.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
listen.backlog = -1
; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
listen.allowed_clients = 127.0.0.1
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0666
listen.owner =
listen.group =
listen.mode = 0666
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user’s group

; Choose how the process manager will control the number of child processes.
; Possible Values:
; static – a fixed number (pm.max_children) of child processes;
; dynamic – the number of child processes are set dynamically based on the
; following directives :
; pm.max_children – the maximum number of children that can
; be alive at the same time.
; pm.start_servers – the number of children created on startup.
; pm.min_spare_servers – the minimum number of children in ‘idle’
; state (waiting to process). If the number
; of ‘idle’ processes is less than this
; number then some children will be created.
; pm.max_spare_servers – the maximum number of children in ‘idle’
; state (waiting to process). If the number
; of ‘idle’ processes is greater than this
; number then some children will be killed.
; Note: This value is mandatory.
pm = static
; The number of child processes to be created when pm is set to ‘static’ and the
; maximum number of child processes to be created when pm is set to ‘dynamic’.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to either ‘static’ or ‘dynamic’
; Note: This value is mandatory.
pm.max_children = 320
; The number of child processes created on startup.
; Note: Used only when pm is set to ‘dynamic’
; Default Value: min_spare_servers + (max_spare_servers – min_spare_servers) / 2
;pm.start_servers = 20
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to ‘dynamic’
; Note: Mandatory when pm is set to ‘dynamic’

; Note: Used only when pm is set to ‘dynamic’
; Note: Mandatory when pm is set to ‘dynamic’
;pm.max_spare_servers = 35
; The number of requests each child process should execute before respawning.

; Default Value: 0
pm.max_requests = 102400
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. By default, the status page shows the following
; information:
; accepted conn – the number of request accepted by the pool;
; pool – the name of the pool;
; process manager – static or dynamic;
; idle processes – the number of idle processes;
; active processes – the number of active processes;
; total processes – the number of idle + active processes.
; max children reached – number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm ‘dynamic’)
; The values of ‘idle processes’, ‘active processes’ and ‘total processes’ are
; updated each second. The value of ‘accepted conn’ is updated in real time.
; Example output:
; accepted conn: 12073
; pool: www
; process manager: static
; idle processes: 35
; active processes: 65
; total processes: 100
; max children reached: 1
; By default the status page output is formatted as text/plain. Passing either
; ‘html’ or ‘json’ as a query string will return the corresponding output
; syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status
; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; – create a graph of FPM availability (rrd or such);
; – remove a server from a group if it is not responding (load balancing);
; – trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
;ping. path = /ping
; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong
; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the ‘max_execution_time’ ini option
; does not stop script execution for some reason. A value of ‘0’ means ‘off’ .
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout =0
; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the ‘slowlog’ file. A value of ‘0s’ means ‘off’.
; Available units: s(econds)(default), m(inutes ), h(ours), or d(ays)
; Default Value: 0
request_slowlog_timeout = 0
; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow
; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024
; Set max core size rlimit.
; Possible Values: ‘unlimited’ or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0
; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with ‘$prefix’ to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, …).
; Default Value: not set
;chroot =
; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www
; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
catch_workers_output = yes
; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp
; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
; php_value/php_flag – you can set classic ini defines which can
; be overwritten from PHP call ‘ini_set’.
; php_admin_value/php_admin_flag – these directives won’t be overwritten by
; PHP call ‘ini_set’
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
; Defining ‘extension’ will load the corresponding shared extension from
; extension_dir. Defining ‘disable_functions’ or ‘disable_classes’ will not
; overwrite previously defined php.ini values, but will append the new value
; instead.
; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/webserver/php)

啟動php-cgi進程
mkdir -p /usr/local/webserver/php/logs/
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm
Step 6：安裝Nginx
安裝pcre 注意pcre並不兼容icc編譯
tar zxvf pcre-8.12.tar.gz
cd pcre-8.12
LD=xild \
AR=xiar \
CFLAGS=’-Os’ \
CXXFLAGS=’-Os’ \
./configure
make
make install
cd ..
ldconfig
安裝nginx
tar zxvf nginx-1.0.3.tar.gz
cd nginx-1.0.3
CC=icc \
CXX=icpc \
LD=xild \
AR=xiar \
CFLAGS=’-O3 -axsse4.2 -ip -unroll2 -no-prec -div -fp-model source -restrict -static-intel’ \
CXXFLAGS=’-O3 -axsse4.2 -ip -unroll2 -no-prec-div -fp-model source -restrict -static-intel -fno-implicit- templates -fno-exceptions -fno-rtti’ \
./configure –user=www –group=www –prefix=/usr/local/webserver/nginx –with-http_stub_status_module –with-http_ssl_module –with- http_flv_module –with-http_gzip_static_module –with-http_geoip_module
make
make install
cd ..
創建nginx配置文件
nano /usr/local/webserver/nginx/conf/nginx.conf
user www www;

{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
access_log on;
}
}
創建 nano /usr/local/webserver/nginx/conf/fcgi.conf
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;

# PHP only, required if PHP was built with –enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
啟動Nginx
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx
創建PHP測試文件
nano /webs/index.php
配置開機啟動
nano /etc/rc.local
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
優化內核參數
nano /etc/sysctl.conf
在末尾添加
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
net.ipv4.ip_local_port_range = 1024 65535
使設置生效
/sbin/sysctl -p
無縫重啟Nginx
/usr/local/webserver/nginx/sbin/nginx -s reload
無縫重啟php
kill -SIGUSR2 `cat /usr/local/webserver/php/logs/php-fpm.pid`
