系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 5.3
一、获取相关开源程序:
1、【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库(RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包,进行安装):
2、【适用CentOS、RedHat及其它Linux操作系统】下载程序源码包:
①、从软件的官方网站下载:
②、从blog.s135.com下载,建议在这里单线程下载!(比较稳定,在Linux/Unix下通过Wget、Curl等命令下载以下软件):
二、安装PHP 5.2.10(FastCGI模式)
1、编译安装PHP 5.2.10所需的支持库:
2、编译安装MySQL 5.5.3-m3
附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下几步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。
①、创建MySQL数据库存放目录
②、以mysql用户帐号的身份建立数据表:
③、创建my.cnf配置文件:
输入以下内容:
[client]
character-set-server = utf8
port = 3306
socket = /tmp/mysql.sock
[mysqld]
character-set-server = utf8
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
user = mysql
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/webserver/mysql
datadir = /data0/mysql/3306/data
log-error = /data0/mysql/3306/mysql_error.log

max_binlog_cache_size = 8M
max_binlog_size = 1G
relay-log-index = /data0/mysql/3306/relaylog/relaylog

relay-log = /data0/mysql/3306/relaylog/relaylog
expire_logs_days = 30
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M

#log-slow-queries = /data0/mysql/3306/slow.log
#long_query_time = 10
[mysqldump]
quick
max_allowed_packet = 32M
④、创建管理MySQL数据库的shell脚本:
输入以下内容(这里的用户名admin和密码12345678接下来的步骤会创建):
mysql_port=3306
mysql_username=”admin”
mysql_password=”12345678″
function_start_mysql()
{
printf “Starting MySQL…\n”
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe –defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf “Stoping MySQL…\n”
/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf “Restarting MySQL…\n”
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep ‘bin/mysqld_safe’ | grep ${mysql_port} | awk ‘{printf $2}’)
kill -9 $(ps -ef | grep ‘libexec/mysqld’ | grep ${mysql_port} | awk ‘{printf $2}’)
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf “Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n”
fi
⑤、赋予shell脚本可执行权限:
⑥、启动MySQL:
⑦、通过命令行登录管理MySQL服务器(提示输入密码时直接回车):
⑧、输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):
⑨、(可选)停止MySQL:
3、编译安装PHP(FastCGI模式)
4、编译安装PHP5扩展模块
5、修改php.ini文件
手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = “./”
修改为extension_dir = “/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/”
并在此行后增加以下几行,然后保存:
extension = “memcache.so”
extension = “pdo_mysql.so”
extension = “imagick.so”
再查找output_buffering = Off
修改为output_buffering = On
自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
6、配置eAccelerator加速PHP:
按shift+g键跳到配置文件的最末尾(按两下g回到页首),加上以下配置信息:
7、创建www用户和组,以及供blog.s135.com和www.s135.com两个虚拟主机使用的目录:
8、创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件:
输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name=”display_errors”>0</value>改为<value name=”display_errors”>1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):
9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为200(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
注:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。
三、安装Nginx 0.8.15
1、安装Nginx所需的pcre库:
2、安装Nginx
3、创建Nginx日志目录
4、创建Nginx配置文件
①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件:
输入以下内容:
user www www;
worker_processes 8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}

gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
server
{
listen 80;
server_name blog.s135.com;
index index.html index.htm index.php;
root /data0/htdocs/blog;
#limit_conn crawler 20;
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 1h;
}
log_format access ’$remote_addr – $remote_user [$time_local] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” $http_x_forwarded_for’;
access_log /data1/logs/access.log access;
}
server
{
listen 80;
server_name www.s135.com;
index index.html index.htm index.php;
root /data0/htdocs/www;
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
log_format wwwlogs ’$remote_addr – $remote_user [$time_local] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” $http_x_forwarded_for’;
access_log /data1/logs/wwwlogs.log wwwlogs;
}
server
{
listen 80;
server_name status.blog.s135.com;
location / {
stub_status on;
access_log off;
}
}
}
②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件:
输入以下内容:
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with –enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
5、启动Nginx
四、配置开机自动启动Nginx + PHP
在末尾增加以下内容:
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
五、优化Linux内核参数
在末尾增加以下内容:
# Add
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_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535
使配置立即生效:
六、在不停止Nginx服务的情况下平滑变更Nginx配置
1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:
如果屏幕显示以下两行信息,说明配置文件正确:
the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully
2、这时,输入以下命令查看Nginx主进程号:
屏幕显示的即为Nginx主进程号,例如:
6302
这时,执行以下命令即可使修改过的Nginx配置文件生效:
或者无需这么麻烦,找到Nginx的Pid文件:
七、编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh
输入以下内容:
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path=”/usr/local/webserver/nginx/logs/”
mkdir -p ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)/
mv ${logs_path}access.log ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)/access_$(date -d “yesterday” +”%Y%m%d”).log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
2、设置crontab,每天凌晨00:00切割nginx访问日志
输入以下内容:
00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
