Nginx-1.4.7+PHP5.5+Tcmalloc的安装配置以及优化
――使用Tcmalloc优化Nginx
注意：如果是系统是64位的话 需要安装libunwind
1）下载libunwind
[root@Nginx ~]# cd /Linux [root@Nginx ~]# wgethttp://ftp.twaren.net/Unix/NonGNU//libunwind/libunwind-1.1.tar.gz
2）安装libunwind
[root@Nginx Linux]# tar fzvx libunwind-1.1.tar.gz [root@Nginx Linux]# cd libunwind-1.1 [root@Nginx libunwind-1.1]# CFLAGS=-fPIC ./configure [root@Nginx libunwind-1.1]# make CFLAGS=-fPIC [root@Nginx libunwind-1.1]# make CFLAGS=-fPIC install
3）安装perftools
[root@Nginx libunwind-1.1]# cd .. [root@Nginx Linux]# wget https://gperftools.googlecode.com/files/gperftools-2.1.tar.gz [root@Nginx Linux]# tar zfvx gperftools-2.1.tar.gz [root@Nginx Linux]# cd gperftools-2.1 [root@Nginx gperftools-2.1]# ./configure --prefix=/usr/local/gperftools [root@Nginx gperftools-2.1]# make && make install [root@Nginx gperftools-2.1]# cp -r /usr/local/gperftools/lib/* /usr/local/lib/ [root@Nginx gperftools-2.1]# mkdir /tmp/tcmalloc [root@Nginx gperftools-2.1]# chmod 0777 /tmp/tcmalloc/
4）安装pcre
[root@Nginx gperftools-2.1]# cd .. [root@Nginx Linux]# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.33.tar.bz2 [root@Nginx Linux]# tar jfvx pcre-8.33.tar.bz2 [root@Nginx Linux]# cd pcre-8.33 [root@Nginx pcre-8.33]# ./configure --prefix=/usr/local/pcre-8.33 \ --enable-utf8 --enable-unicode-properties
――安装编译Nginx
1）下载Nginx
[root@Nginx pcre-8.33]# cd .. [root@Nginx Linux]# useradd -M -s /sbin/nologin nginx [root@Nginx Linux]# wget http://nginx.org/download/nginx-1.4.7.tar.gz
2）编译安装Nginx
[root@Nginx Linux]# tar zfvx nginx-1.4.7.tar.gz [root@Nginx Linux]# cd nginx-1.4.7 [root@Nginx nginx-1.4.7]# ./configure \ --user=nginx \ --group=nginx \ --with-http_ssl_module \ --with-http_realip_module \ --with-http_addition_module \ --with-http_gzip_static_module \ --with-http_sub_module \ --with-http_dav_module \ --with-http_flv_module \ --with-http_stub_status_module \ --without-http_charset_module \ --with-google_perftools_module \ --with-pcre=/Linux/pcre-8.33 #注意 是pcre的源码包路径、不是安装路径 [root@Nginx nginx-1.4.7]# make && make install
3）配置Nginx
[root@Nginx nginx-1.4.7]# vi /usr/local/nginx/conf/nginx.conf
#用户和组
user nginx nginx;
#进程数【和CPU颗数相等】
worker_processes 8;
#将每一个进程绑定到一个CPU [8颗CPU]
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000

}
4）创建虚拟主机
[root@Nginx nginx-1.4.7]# mkdir /usr/local/nginx/conf/conf.d
[root@Nginx nginx-1.4.7]# cd /usr/local/nginx/conf/conf.d/
[root@Nginx conf.d]# vi www.nagix.com.conf
server {
#端口
listen 80;
#域名
server_name www.nginx.com;
#存放路径
root /usr/local/nginx/html;
#首页类型
index index.html index.htm index.php
#错误日志
error_log logs/www.nginx.com_error.log;
location ~ \.php$ {
root /usr/local/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
5）添加启动脚本
[root@Nginx conf.d]# vi /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig: 35 86 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
lockfile=/var/lock/subsys/nginx
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart|configtest)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;
status)
rh_status
;;

rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
6）设置开机启动
[root@Nginx conf.d]# chmod +x /etc/init.d/nginx [root@Nginx conf.d]# chkconfig --add nginx [root@Nginx conf.d]# chkconfig nginx on
7）启动nginx
[root@Nginx conf.d]# service nginx start 正在启动nginx：/usr/local/nginx/sbin/nginx: error while loading shared libraries: libprofiler.so.0: cannot open shared object file: No such file or directory [失败]
正在启动nginx：/usr/local/nginx/sbin/nginx: error while loading shared libraries: libprofiler.so.0: cannot open shared object file: No such file or directory
[失败]
解决办法：
[root@Nginx conf.d]# ln -s /usr/local/lib/libunwind.so /lib64/libunwind.so.8 [root@Nginx conf.d]# ln -s /usr/local/lib/libprofiler.so.0 /lib64 [root@Nginx conf.d]# service nginx start 正在启动 nginx：[确定] [root@Nginx conf.d]# netstat -antup |grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 32981/nginx
――编译安装PHP
1）安装软件依赖包
[root@Nginx Linux]# yum install libxml2-devel bzip2-devel curl curl-devel libjpeg-devel freetype-devel gmp-devel mysql-devel unixODBC-devel libpng-devel libxslt-devel
2）下载PHP
[root@Nginx Linux]# wget http://at2.php.net/distributions/php-5.5.4.tar.gz
3）编译安装
[root@Nginx Linux]# tar zfxv php-5.5.4.tar.gz [root@Nginx Linux]# cd php-5.5.4 [root@Nginx php-5.5.4]# ./configure --prefix=/usr/local/php-5.5 \ --enable-safe-mode \ --enable-zip \ --with-bz2 \ --with-jpeg-dir=/usr/include \ --with-png-dir=/usr/include/libpng12 \ --with-freetype-dir=/usr/include/freetype2/freetype \ --with-libxml-dir=/usr/include/libxml2/libxml \ --with-xmlrpc \ --with-zlib \ --with-gd \ --with-curl \ --with-xsl \ --with-gettext \ --with-pear \ --enable-mbstring \ --enable-bcmath \ --enable-sockets \ --enable-exif \ --enable-fpm \ --with-openssl \ --with-pcre \ --with-mysql=/usr/local/mysql-5.5 \ --with-mysqli=/usr/local/mysql-5.5/bin/mysql_config \ --with-config-file-path=/usr/local/php-5.5/etc/ \ [root@Nginx php-5.5.4]# make && make install [root@Nginx php-5.5.4]# cp php.ini-production /usr/local/php-5.5/etc/php.ini [root@Nginx php-5.5.4]# cp /usr/local/php-5.5/etc/php-fpm.conf.default \ > /usr/local/php-5.5/etc/php-fpm.conf
4）配置PHP
[root@Nginx php-5.5.4]# vi /etc/profile PATH=/usr/local/php-5.5/bin:$PATH PATH=/usr/local/php-5.5/sbin:$PATH [root@Nginx php-5.5.4]# vi /usr/local/php-5.5/etc/php-fpm.conf ;pid = run/php-fpm.pid pid = run/php-fpm.pid#取消注释
5）设置php-fpm开机启动
[root@Nginx php-5.5.4]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm [root@Nginx php-5.5.4]# chmod +x /etc/init.d/php-fpm [root@Nginx php-5.5.4]# chkconfig --add php-fpm [root@Nginx php-5.5.4]# chkconfig php-fpm on [root@Nginx php-5.5.4]# service php-fpm start [root@Nginx php-5.5.4]# netstat -antup |grep 9000 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 25686/php-fpm
6）添加测试页面
[root@Nginx php-5.5.4]# vi /usr/local/nginx/html/index.php <?php phpinfo(); ?>
[root@Nginx conf.d]# curl http://www.nginx.com/index.php
如果解析没有问题的话、说明安装成功。环境有限，我在这里使用的是命令行访问WEB、大家使用客户端网页访问：http://www.nginx.com/index.php
