基于CentOS 5.4搭建nginx+php+spawn-fcgi+mysql高性能php平台
一、安装准备 1.1平台环境：
- CentOS 5.4 x86_64 GNU/Linux
- nginx-0.8.21
- php-5.2.9
- spawn-fcgi-1.6.3
- mysql-5.1.34
.2系统安装及分区：
1.2.1操作系统安装：
安装过程中选择最少的包，采用文本模式安装，不安装图形。
1.2.3系统分区：
/boot 100M (大约100左右)
SWAP 4G 物理内存的2倍(如果你的物理内存大于4G，分配4G即可)
/ 50G
/data 剩余所有空间.
注：具体分区请根据相关业务划分
1.2.4系统软件包安装规范
系统约定:
软件源代码包存放位置 /usr/local/src
源码包编译安装位置(prefix) /usr/local/software_name
脚本以及维护程序存放位置 /usr/local/sbin
MySQL 数据库位置 /data/mysql/data（可按情况设置）
网站根目录 /data/www/wwwroot（可按情况设置）
虚拟主机日志根目录 /data/logs（可按情况设置）
Nginx运行账户 www:www
install_software_name.sh //存放编译参数脚本习惯将所有编译脚本存放在install_software_name.sh便于升级和更新软件.
1.3.系统初始化
#vi init_network.sh
#welcome cat << EOF +--------------------------------------------------------------+ | === Welcome to Centos System init === | +--------------------------------------------------------------+ +----------------------Author:NetSeek--------------------------+ EOF #disable ipv6 cat << EOF +--------------------------------------------------------------+ | === Welcome to Disable IPV6 === | +--------------------------------------------------------------+ EOF echo "alias net-pf-10 off" >> /etc/modprobe.conf echo "alias ipv6 off" >> /etc/modprobe.conf /sbin/chkconfig --level 35 ip6tables off echo "ipv6 is disabled!" #disable selinux sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config echo "selinux is disabled,you must reboot!" #vim sed -i "8 s/^/alias vi='vim'/" /root/.bashrc echo 'syntax on' > /root/.vimrc #zh_cn sed -i -e 's/^LANG=.*/LANG="en"/' /etc/sysconfig/i18n #init_ssh ssh_cf="/etc/ssh/sshd_config" sed -i -e '74 s/^/#/' -i -e '76 s/^/#/' $ssh_cf sed -i "s/#UseDNS yes/UseDNS no/" $ssh_cf #client sed -i -e '44 s/^/#/' -i -e '48 s/^/#/' $ssh_cf echo "ssh is init is ok.............." #chkser #tunoff services #-------------------------------------------------------------------------------- cat << EOF +--------------------------------------------------------------+ | === Welcome to Tunoff services === | +--------------------------------------------------------------+ EOF #--------------------------------------------------------------------------------- for i in `ls /etc/rc3.d/S*` do CURSRV=`echo $i|cut -c 15-` echo $CURSRV case $CURSRV in crond | irqbalance | microcode_ctl | network | random | sendmail | sshd | syslog | local | mysqld ) echo "Base services, Skip!" ;; *) echo "change $CURSRV to off" chkconfig --level 235 $CURSRV off service $CURSRV stop ;; esac done
1.4 系统环境部署及调整
检查系统是否正常
# tail -n100 /var/log/messages （检查有无系统级错误信息）
# dmesg （检查硬件设备是否有错误信息）
# ifconfig （检查网卡设置是否正确）
# ping www.cqseo.org （检查网络是否正常）
1.5使用 yum 程序安装所需开发包
1.5.1 更换快源
#cd /etc/yum.repos.d/
#mv CentOS-Base.repo CentOS-Base.repo.linuxtone
#wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
1.5.2 yum安装相关软件包:
#yum -y install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel libtool* zlib-devel libxml2-devel libjpeg-devel libpng-devel libtiff-devel fontconfig-devel freetype-devel libXpm-devel gettext-devel curl curl-devel pam-devel e2fsprogs-devel krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
1.6 定时校正服务器时钟，定时与中国国家授时中心授时服务器同步
# crontab -e
加入一行： 15 3 * * * /usr/sbin/ntpdate 210.72.145.44 > /dev/null 2>&1
1.7下载相关软件包
#cd /usr/local/src
#vi list_tar.list
http://docs.linuxtone.org/soft/lemp/ImageMagick.tar.gz
http://docs.linuxtone.org/soft/lemp/PDO_MYSQL-1.0.2.tgz

http://docs.linuxtone.org/soft/lemp/ZendOptimizer-3.3.3-linux-glibc23-x86_64.tar.gz
#wget -i list_tar.list
1.8.添加nginx 运维账户:
#vi add_webuser.sh
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data/www/wwwroot
chmod +w /data/www/wwwroot
chown www:www /data/www/wwwroot -R
#sh add_webuser.sh
二.编译安装
2.1 编译安装pcre
#tar zxvf pcre-7.8.tar.gz
#cd pcre-7.8
#./configure && make && make install
2.2 编译安装nginx
#tar zxvf nginx-0.8.21.tar.gz
#cd nginx-0.8.21
2.2.1 附加：修改nginx源代码，伪装nginx服务器（仅供参考，安全还得认真做起^.^）：
(1).修改gcc
#vi auto/cc/gcc
NGX_GCC_OPT="-O"
NGX_GCC_OPT="-O3"
(2).修改nginx.h
#vi nginx-0.8.21/src/core/nginx.h
#define NGINX_VERSION "0.7.58"
#define NGINX_VER "nginx/" NGINX_VERSION
修改为：
#define NGINX_VERSION "1.0"
#define NGINX_VER "LTWS/" NGINX_VERSION
(3).修改nginx_http_header_filter_module
#vi nginx-0.8.21/src/http/ngx_http_header_filter_module.c
static char ngx_http_server_string[] = "Server: nginx" CRLF;
修改为:
static char ngx_http_server_string[] = "Server: LTWS" CRLF;
(4).修改ngx_http_special_response.c
#vi nginx-0.8.21/src/http/ngx_http_special_response.c
将如下
static u_char ngx_http_error_full_tail[] =
"<hr><center>" NGINX_VER "</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;
static u_char ngx_http_error_tail[] =
"<hr><center>nginx</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;
static u_char ngx_http_error_full_tail[] =
"<hr><center> "NGINX_VER" </center>" CRLF
"<hr><center>http://www.linuxtone.com</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;
static u_char ngx_http_error_tail[] =
"<hr><center>HMGWS</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

2.4.5脚本配置php.ini
# vi init_php.sh
#!/bin/bash fcgi_cf="/usr/local/php/etc/php.ini" ea(){ cat << EOF [eAccelerator] zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so" eaccelerator.shm_size="32" eaccelerator.cache_dir="/data/cache/ea" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="0" eaccelerator.shm_prune_period="0" eaccelerator.shm_only="0" eaccelerator.compress="1" eaccelerator.compress_level="9" EOF } #mkdir mkdir -p /data/cache/ea ea >> $fcgi_cf #config for php.ini sed -i '205 s#;open_basedir =#open_basedir = /data/www/wwwroot:/tmp#g' $fcgi_cf sed -i '210 s#disable_functions =#;disable_functions = phpinfo,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server#g' $fcgi_cf sed -i '/expose_php/s/On/Off/' $fcgi_cf sed -i '/display_errors/s/On/Off/' $fcgi_cf sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' $fcgi_cf sed -i 's#output_buffering = Off#output_buffering = On#' $fcgi_cf
2.5安装Zend
#tar zvxf ZendOptimizer-3.3.3-linux-glibc23-x86_64.tar.gz # cd ZendOptimizer-3.3.3-linux-glibc23-x86_64 # ./install
注：php.ini的位置为/usr/local/php/etc 服务器不选用apache
三、配置整合
3.1 配置nginx
注：本文spawn-fcgi开启9000跟9001两个端口，利用nginx的upstream负载均衡php程序到不同的fcgi端口上面，解决502 gateway错误
#cd /usr/local/nginx/conf
#cp nginx.conf nginx.conf.linuxtone
#vi nginx.conf

#mkdir vhosts

3.2 配置spawn-fcgi启动脚本
#mkdir /usr/local/php/sbin
# vi /usr/local/php/sbin/spawn-fcgi
#! /bin/sh set -e PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DESC="spawn-fcgi daemon" NAME=spawn-fcgi DAEMON=/usr/local/bin/$NAME # Gracefully exit if the package has been removed. test -x $DAEMON || exit 0 d_start() { $DAEMON -a 127.0.0.1 -p 9000 -C 128 -u www -g www -f /usr/local/php/bin/php-cgi > /dev/null 2>&1 $DAEMON -a 127.0.0.1 -p 9001 -C 128 -u www -g www -f /usr/local/php/bin/php-cgi > /dev/null 2>&1 || echo -n " already running" } d_stop() { /usr/bin/killall -9 php-cgi > /dev/null 2>&1 || echo -n " not running" } case "$1" in start) echo -n "Starting $DESC: $NAME" d_start echo "." ;; stop) echo -n "Stopping $DESC: $NAME" d_stop echo "." ;; restart) echo -n "Restarting $DESC: $NAME" d_stop sleep 1 d_start echo "." ;; *) echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2 exit 3 ;; esac exit 0
#chmod 755 /usr/local/php/sbin/spawn-fcgi
四、启动WEB服务
4.1.启动spawn-fcgi
#/usr/local/php/sbin/spawn-fcgi start
4.2.启动nginx
4.2.1检查nginx配置：
# /usr/local/nginx/sbin/nginx ?t //返回如下信息说明配置正确
the configuration file /usr/local/nginx//conf/nginx.conf syntax is ok configuration file /usr/local/nginx//conf/nginx.conf test is successful
#/usr/local/nginx/sbin/nginx //启动nginx
4.3.加入开机启动
#vi /etc/rc.local
在最后加入：
ulimit -SHn 51200 /usr/local/nginx/sbin/nginx /usr/local/php/sbin/spawn-fcgi start
五、测试
#mkdir /data/www/wwwroot/linuxtone
#vi phpinfo.php
<?php
Phpinfo();
?>
打开浏览器输入：http://www.linuxtone.org/phpinfo.php
即可查看当前配置环境. 查看完成后出于安全考虑请再将此函数禁掉.
