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：
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。
三、安装Nginx 0.7.51
1、安装Nginx所需的pcre库：
tar zxvf pcre-7.8.tar.gz
cd pcre-7.8/
./configure
make && make install
cd ../
2、安装Nginx
tar zxvf nginx-0.7.51.tar.gz
cd nginx-0.7.51/
./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.

#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)$
{

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

}
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data1/logs/access.log access;
}
server
{
listen 80;
server_name ;
index index.html index.htm index.php;
root /data0/htdocs/www;
location ~ .*\.(php|php5)?$
{
#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 51200
/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 51200
/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
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
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、这时，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
TCMalloc（Thread-Caching Malloc）是google开发的开源工具%解功能，其中包括用于输出堆栈跟踪的
API、用于以编程方式辗转开解堆栈的API以及支持C++异常处理机制的API。
代码:
wget
tar zxvf libunwind-0.99.tar.gz
cd libunwind-0.99/
CFLAGS=-fPIC ./configure
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
2、安装google-perftools：
wget
tar zxvf google-perftools-0.97.tar.gz
cd google-perftools-0.97/
./configure
make && make install
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig
3、修改MySQL启动脚本（根据你的MySQL安装位置而定）：
vi /usr/local/mysql/bin/mysqld_safe
在# executing mysqld_safe的下一行，加上：
引用
export LD_PRELOAD=/usr/local/lib/libtcmalloc.so
保存后退出，然后重启MySQL服务器。
4、使用lsof命令查看tcmalloc是否起效：
/usr/sbin/lsof -n | grep tcmalloc
