LNMP CentOS 6.x fastcgi spawn-fcgi v1

ling3

　　LNMP在CentOS 6下的配置与LNMP在CentOS 5下的配置区别不大，主要区别是使用的EPEL源不同，版本要高一些，里面的RPM包的版本也要高一些。

一、系统更新
　　在准备配置LNMP环境的时候我们把系统更新到最新

yum update
二、安装nginx

1、自动(yum)安装nginx，使用EPEL源安装

rpm -Uvh http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum update
yum install nginx sudo
　　这样安装的nginx版本应该是0.8.54，不会是nginx官方最新稳定版本。使用最新版请用2步骤，如果不需要请跳过2。

2、使用nginx官方源安装

rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
yum install nginx
3、设为开机启动

/etc/init.d/nginx start
chkconfig --add nginx
chkconfig nginx on
三、安装PHP使用FastCGI

1、安装PHP
　　这里我们使用spawn-fcgi来管理php-fastcgi。

yum install php-cli php spawn-fcgi wget
　　注：如果是想安装php所有扩展，使用：

yum install php php-* spawn-fcgi wget
　　建立php-fastcgi服务，需要新建文件/usr/bin/php-fastcgi，输入以下内容：

#!/bin/sh
if [ `grep -c "nginx" /etc/passwd` = "1" ]; then
FASTCGI_USER=nginx
elif [ `grep -c "www-data" /etc/passwd` = "1" ]; then
FASTCGI_USER=www-data
elif [ `grep -c "http" /etc/passwd` = "1" ]; then
FASTCGI_USER=http
else
# Set the FASTCGI_USER variable below to the user that
# you want to run the php-fastcgi processes as
FASTCGI_USER=
fi
/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 6 -u $FASTCGI_USER -f /usr/bin/php-cgi
　　新建/etc/init.d/php-fastcgi，输入以下内容：

#!/bin/sh
# php-fastcgi - Use php-fastcgi to run php applications
#
# chkconfig: - 85 15
# description: Use php-fastcgi to run php applications
# processname: php-fastcgi
if [ `grep -c "nginx" /etc/passwd` = "1" ]; then
OWNER=nginx
elif [ `grep -c "www-data" /etc/passwd` = "1" ]; then
OWNER=www-data
elif [ `grep -c "http" /etc/passwd` = "1" ]; then
OWNER=http
else
# Set the OWNER variable below to the user that
# you want to run the php-fastcgi processes as
OWNER=
fi
PATH=/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/bin/php-fastcgi
NAME=php-fastcgi
DESC=php-fastcgi
test -x $DAEMON || exit 0
# Include php-fastcgi defaults if available
if [ -f /etc/default/php-fastcgi ] ; then
. /etc/default/php-fastcgi
fi
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
sudo -u $OWNER $DAEMON
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
killall -9 php-cgi
echo "$NAME."
;;
restart)
echo -n "Restarting $DESC: "
killall -9 php-cgi
sleep 1
sudo -u $OWNER $DAEMON
echo "$NAME."
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart}" >&2
exit 1
;;
esac
exit 0
　　设为开机启动

chmod +x /usr/bin/php-fastcgi
chmod +x /etc/init.d/php-fastcgi
service php-fastcgi start
chkconfig --add php-fastcgi
chkconfig php-fastcgi on
　　修改/etc/sudoers，在Defaults requiretty加#号

# Defaults requiretty
2、配置nginx with PHP的虚拟机
　　在/etc/nginx/conf.d中新建example.com.conf(example.com是你的域名哦，不要写错了，/srv/www/example.com/public_html是你的网站存放目录)，输入以下内容：

server {
server_name www.example.com example.com;
access_log /srv/www/example.com/logs/access.log;
error_log /srv/www/example.com/logs/error.log;
root /srv/www/example.com/public_html;
location / {
index index.html index.htm index.php;
}
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass  127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /srv/www/example.com/public_html$fastcgi_script_name;
}
}
　　重启nginx就可以了

/etc/init.d/nginx restart
四、安装MySQL数据库
　　安装MysSQL Server

yum install mysql-server php-mysql
/etc/rc.d/init.d/mysqld start
chkconfig mysqld on
　　安全配置

mysql_secure_installation
mysql -u root -p
　　这个时候需要输入MYSQL密码，是否允许外部域链接数据库等设置，你可以根据提示完成密码设置，我们这里不详细介绍了。

五、完成LNMP的安装
　　重启PHP

/etc/init.d/php-fastcgi restart
　　所有LNMP在CentOS 6下的配置就完成了
