centos5.5系统的php+mysql+nginx配置

一、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）：

# yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libpng libpng-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel

二、安装PHP 5.2.6（FastCGI模式）

　　1、编译安装PHP 5.2.6所需的支持库：

tar zxvf libiconv-1.12.tar.gz

cd libiconv-1.12/

./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.tar.gz

cd mhash-0.9.9/

./configure

make

make install

cd ../

cp /usr/local/lib/libmcrypt.* /usr/lib

ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

tar zxvf mcrypt-2.6.7.tar.gz

cd mcrypt-2.6.7/

./configure

make

make install

cd ../

-----------------------------------------------------------------

　　2、编译安装MySQL 5.1.56

useradd -g mysql

./configure --with-mysqld-user=mysql --prefix=/usr/local/webserver/mysql5 --with-charset=gbk --with-extra-charset=all --without-isam --exec-prefix=/usr/local/webserver/mysql5 --with-unix-socket-path=/usr/local/webserver/mysql5/var/mysql.sock

make;make install

/usr/local/webserver/mysql5/bin/mysql_install_db --user=mysql

cp /usr/local/webserver/mysql5/share/mysql/my-medium.cnf /usr/local/webserver/mysql5/var/my.cnf

cp /usr/local/webserver/mysql5/share/mysql/mysql.server /etc/init.d/mysqld

chmod 700 /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 2345 mysqld on

chown mysql:mysql -R /usr/local/webserver/mysql5/

vi /usr/local/webserver/mysql5/var/my.cnf

# 添加 max_connections=1000

service mysqld start

ln -s /usr/local/webserver/mysql5/bin/mysql_config /usr/bin/mysql_config

ln -s /usr/local/webserver/mysql5/bin/mysql /sbin/mysql

ln -s /usr/local/webserver/mysql5/bin/mysqladmin /sbin/mysqladmin

#配置库文件搜索路径

echo "/usr/local/webserver/mysql5/lib/mysql" >> /etc/ld.so.conf

ldconfig -v

#添加/usr/local/mysql/bin到环境变量PATH中

export PATH=$PATH:/usr/local/webserver/mysql5/bin

-----------------------------------------------------------------

3、编译安装PHP（FastCGI模式）

yum install openldap-devel

tar zxvf php-5.3.0.tar.gz

gzip -cd /mnt1/php-5.3.0-fpm-0.5.12.diff.gz | patch -d php-5.3.0 -p1

cd php-5.2.6/

./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-liconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-debug --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

sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile

make

make install

cp php.ini-dist /usr/local/webserver/php/etc/php.ini

cd ../

tar jxvf eaccelerator-0.9.6.tar.bz2

/usr/local/webserver/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

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-2.2.2.tgz

cd imagick-2.2.2/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

----------------------------------------------------------------

若看到相关的php信息页面，则证明php也配置成功！！

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 ../

----------------------------------------------------------------

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 = extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20090626/

　　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

-----------------------------------------------------------------

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-20090626/eaccelerator.so"

eaccelerator.shm_size="128"

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="300"

eaccelerator.shm_prune_period="120"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

　修改配置文件：

vi /etc/sysctl.conf

输入以下内容：

kernel.shmmax = 134217728

然后执行以下命令使配置生效：

/sbin/sysctl -p

-----------------------------------------------------------------

7、创建www用户和组

useradd www

chmod +w /var/www

chown -R www:www /var/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：

mv /usr/local/webserver/php/etc/php-fpm.conf /usr/local/webserver/php/etc/php-fpm.conf.bak

vi /usr/local/webserver/php/etc/php-fpm.conf

输入一下内容

<?xml version="1.0" ?>

<configuration>

<section name="global_options">

<value name="pid_file">/usr/local/webserver/php/logs/php-fpm.pid</value>

<value name="error_log">/usr/local/webserver/php/logs/php-fpm.log</value>

<value name="log_level">notice</value>

<value name="emergency_restart_threshold">10</value>

<value name="emergency_restart_interval">1m</value>

<value name="process_control_timeout">5s</value>

<value name="daemonize">yes</value>

</section>

<workers>

<section name="pool">

<value name="name">default</value>

<value name="listen_address">127.0.0.1:9000</value>

<value name="listen_options">

<value name="backlog">-1</value>

<value name="owner"></value>

<value name="group"></value>

<value name="mode">0666</value>

</value> <value name="php_defines">

<value name="sendmail_path">/usr/sbin/sendmail -t -i</value>

<value name="display_errors">1</value>

</value> <value name="user">www</value>

<value name="group">www</value>

<value name="pm">

<value name="style">static</value>

<value name="max_children">128</value>

<value name="apache_like">

<value name="StartServers">20</value>

<value name="MinSpareServers">5</value>

<value name="MaxSpareServers">35</value>

</value>

</value>

<value name="request_terminate_timeout">0s</value>

<value name="request_slowlog_timeout">0s</value>

<value name="slowlog">logs/slow.log</value>

<value name="rlimit_files">51200</value>

<value name="rlimit_core">0</value>

<value name="chroot"></value>

<value name="chdir"></value>

<value name="catch_workers_output">yes</value>

<value name="max_requests">500</value>

<value name="allowed_clients">127.0.0.1</value>

<value name="environment">

<value name="HOSTNAME">$HOSTNAME</value>

<value name="PATH">/usr/local/bin:/usr/bin:/bin</value>

<value name="TMP">/tmp</value>

<value name="TMPDIR">/tmp</value>

<value name="TEMP">/tmp</value>

<value name="OSTYPE">$OSTYPE</value>

<value name="MACHTYPE">$MACHTYPE</value>

<value name="MALLOC_CHECK_">2</value>

</value>

</section>

</workers>

</configuration>

----------------------------------------------------------------

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25个进程），用户为www：

ulimit -SHn 51200

/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

-----------------------------------------------------------------

10、优化Linux内核参数

vi /etc/sysctl.conf

　　在末尾增加以下内容：

引用

net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_keepalive_time = 300

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_tw_recycle = 1

net.ipv4.ip_local_port_range = 5000 65000

　　使配置立即生效：

/sbin/sysctl -p

----------------------------------------------------------------

三、安装Nginx 0.8.35

　　1、安装Nginx所需的pcre库：

tar zxvf pcre-7.7.tar.gz

cd pcre-7.7/

./configure

make && make install

cd ../

----------------------------------------------------------------

2、安装Nginx

# tar -zxvf /mnt1/nginx-0.8.35.tar.gz

cd nginx-0.8.35/

./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 /var/www/logs

chmod +w /var/www/logs

chown -R www:www /var/www/logs/

ln -s /var/www ../webserver/nginx/www

ln -s /var/www/logs ../webserver/nginx/logs

----------------------------------------------------------------

4、创建Nginx配置文件

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

user www www;

worker_processes 8;

error_log /usr/local/webserver/nginx/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;

}

http

{

include mime.types;

default_type application/octet-stream;

#charset gb2312;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 8m;

sendfile on;

#以下两个选项用于防止网络阻塞

tcp_nopush on;

tcp_nodelay on;

keepalive_timeout 60;

fastcgi_connect_timeout 300;

fastcgi_send_timeout 300;

fastcgi_read_timeout 300;

fastcgi_buffer_size 64k;

fastcgi_buffers 4 64k;

fastcgi_busy_buffers_size 128k;

fastcgi_temp_file_write_size 128k;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_http_version 1.0;

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 /var/www/htdoc;

#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 1d;

}

location ~ .*\.(js|css)?$

{

expires 1h;

}

location /NginxStatus {

stub_status on;

access_log on;

auth_basic "NginxStatus";

auth_basic_user_file conf/htpasswd;

allow 192.168.186.53;

deny all;

}

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 /var/www/logs/access.log access;

}

}

在上面有设置查看Nginx状态的地址,需要apache的htpasswd 来生成一个登录验证文件,这样生成一个htpasswd 文件:

[root@oracle132 vhosts]# /usr/local/bin/htpasswd -c htpasswd xh_l

New password: (此处输入您的密码)

Re-type new password: (再次输入您的密码)

Adding password for user xh_l

上面 /usr/local/bin/htpasswd 是htpasswd 文件的执行路径,如果没有这个文件,可以从apache的bin目录拷贝一个过来即可!

-c是创建一个文件

-c后面的httpasswd是创建验证文件的名字.

xh_l是创建的用户

5、 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：

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;

----------------------------------------------------------------

6、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：

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_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

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：

　　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

----------------------------------OK,配置完成-------------------------------

测试：

1.启动nginx：/usr/local/webserver/nginx/sbin/nginx

2.启动php-fpm：/usr/local/webserver/php/sbin/php-fpm start

3.通过ip访问服务器，出现：Welcome to Nginx！说明Nginx服务已开启！

4.php测试，在Nginx的web根下建立：info.php

<?php

phpinfo();

?>
