Nginx 0.8.x + PHP 5.2.13（FastCGI）搭建胜过Apache十倍的W...

　安装步骤：
　　（系统要求：Linux 2.6+ 内核，本文中的Linux操作系统为CentOS 5.3，另在RedHat AS4上也安装成功）

　　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）：
sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers


　　2、【适用RedHat操作系统】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（事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在，通常是“xxx-devel”不存在，需要安装）。RedHat可以直接利用CentOS的RPM包安装，以下是RPM包下载网址：
　　①、RedHat AS4 & CentOS 4
　　http://mirrors.163.com/centos/4/os/i386/CentOS/RPMS/
　　http://mirrors.163.com/centos/4/os/x86_64/CentOS/RPMS/

　　②、RedHat AS5 & CentOS 5
　　http://mirrors.163.com/centos/5/os/i386/CentOS/
　　http://mirrors.163.com/centos/5/os/x86_64/CentOS/

　　③、RPM包搜索网站

wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.3.0.tgz


　　二、安装PHP 5.2.14（FastCGI模式）
　　1、编译安装PHP 5.2.14所需的支持库：
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../


　　2、编译安装MySQL 5.5.3-m3
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-5.5.3-m3/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ../


　　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
mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/


　　②、以mysql用户帐号的身份建立数据表：
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql


　　③、创建my.cnf配置文件：
vi /data0/mysql/3306/my.cnf

　　输入以下内容：
引用
[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
pid-file = /data0/mysql/3306/mysql.pid
open_files_limit = 10240
back_log = 600
max_connections = 5000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 1M
join_buffer_size = 1M
thread_cache_size = 300
#thread_concurrency = 8
query_cache_size = 512M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 3
log-slave-updates
log-bin = /data0/mysql/3306/binlog/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 1G
relay-log-index = /data0/mysql/3306/relaylog/relaylog
relay-log-info-file = /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
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover

interactive_timeout = 120
wait_timeout = 120

skip-name-resolve
#master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

#master-host = 192.168.1.2
#master-user = username
#master-password = password
#master-port = 3306

server-id = 1

innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 512M
innodb_data_file_path = ibdata1:256M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = 0

#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：
vi /data0/mysql/3306/mysql

　　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）：
#!/bin/sh

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：
chmod +x /data0/mysql/3306/mysql


　　⑥、启动MySQL：
/data0/mysql/3306/mysql start


　　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）：
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock


　　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）：
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';


　　⑨、（可选）停止MySQL：
/data0/mysql/3306/mysql stop


　　3、编译安装PHP（FastCGI模式）
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/webserver/php/etc/php.ini
cd ../


　　4、编译安装PHP5扩展模块
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../


　　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

　　再查找; cgi.fix_pathinfo=0
　　修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。

　　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：
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini


　　6、配置eAccelerator加速PHP：
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/php/etc/php.ini

　　按shift+g键跳到配置文件的最末尾，加上以下配置信息：
引用
[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"



　　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：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www


　　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：
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vi /usr/local/webserver/php/etc/php-fpm.conf

　　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128（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start

　　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 0.8.46
　　1、安装Nginx所需的pcre库：
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ../


　　2、安装Nginx
tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../


　　3、创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs


　　4、创建Nginx配置文件
　　①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：
rm -f /usr/local/webserver/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf

　　输入以下内容：
引用
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;

#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：
vi /usr/local/webserver/nginx/conf/fcgi.conf

　　输入以下内容：
引用
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
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx


　　四、配置开机自动启动Nginx + PHP
vi /etc/rc.local

　　在末尾增加以下内容：
引用
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
vi /etc/sysctl.conf

　　在末尾增加以下内容：
引用
# 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：
/sbin/sysctl -p


　　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：
/usr/local/webserver/nginx/sbin/nginx -t

　　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、平滑重启：
　　①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：
/usr/local/webserver/nginx/sbin/nginx -s reload


　　②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

　　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：
kill -HUP 6302

　　或者无需这么麻烦，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`


　　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
vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

　　输入以下内容：
引用
#!/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
crontab -e

　　输入以下内容：
引用
00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
