Nginx优化
Nginx以事件驱动（epoll）的方式编写，所以有非常好的性能，同时也是一个非常高效的反向代理、负载平衡。但是Nginx并不支持cgi方式运行，原因是可以减少因此带来的一些程序上的漏洞。所以必须使用FastCGI方式来执行PHP程序。
由于Nginx本身的一些优点，轻量，开源，易用，越来越多的公司使用nginx作为自己公司的web应用服务器，本文详细介绍nginx源码安装的同时并对nginx进行优化配置。
一、Nginx的优化
1、编译安装前优化
编译前的优化主要是用来修改程序名等等，目的更改源码隐藏软件名称和版本号
安装zlib-devel、pcre-devel等依赖包
|
1
|
[root@CXW /]# yum -y install gcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel openssl openssl-devel
|
下载nginx的源码包：http://nginx.org/download
解压源码包：
|

|
[root@CXW /]# tar zxf nginx-
1.10
.
2
.tar.gz
[root@CXW /]# cd nginx-
1.10
.
2
/
|
隐藏软件名称和版本号
[root@CXW nginx-1.10.2]# vim src/core/nginx.h
//此行修改的是你想要的版本
#define NGINX_VERSION "1.22.22" //第13行
//此行修改的是你想修改的软件名称
#define NGINX_VER "nginx/" NGINX_VERSION //第14行
修改上面的信息，即可更改nginx显示版本。例如：
#define NGINX_VERSION "7.0"
#define NGINX_VER "IIS/" NGINX_VERSION
修改HTTP头信息中的connection字段，防止回显具体版本号
拓展：通用http头，通用头包含请求和响应消息都支持的头，通用头包含Cache-Control、 Connection、Date、Pragma、Transfer-Encoding、Upgrade、Via。对通用头的扩展要求通讯双方都支持此扩展，如果存在不支持的通用头，一般将会作为实体头处理。那么也就是说有部分设备，或者是软件，能获取到connection，部分不能，要隐藏就要彻底！
[root@CXW nginx-1.10.2]# vim src/http/ngx_http_header_filter_module.c
修改前：
static char ngx_http_server_string[] = "Server: nginx" CRLF; //第49行
修改后：
static char ngx_http_server_string[] = "Server: CXW" CRLF;

修改前
static u_char ngx_http_error_tail[] = //第29行
"<hr><center>nginx</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

修改后

CRLF
"</html>"
CRLF
;

2、安装ngnix

[root@CXW nginx-

3、nginx配置项优化
[root@CXW nginx-1.10.2]# ps -ef | grep nginx
root 7935 1 0 17:24 ? 00:00:00 nginx: master process nginx
www 7936 7935 0 17:24 ? 00:00:00 nginx: worker process
root 8125 4969 0 17:30 pts/1 00:00:00 grep --color=auto nginx
在这里我们还可以看到在查看的时候，work进程是nginx程序用户，但是master进程还是root，其中，master是监控进程，也叫主进程，work是工作进程
(1):Nginx运行工作进程个数，一般我们设置CPU的核心或者核心数x2
如果不了解cpu的核数，可以top命令之后按1也可以看出来，也可以查看/proc/cpuinfo文件#grep ^processor /proc/cpuinfo | wc -l

nginx: worker process
|
Nginx运行CPU亲和力
比如4核配置
worker_processes 4;
worker_cpu_affinity 0001 0010 0100 1000
比如8核配置
worker_processes 8;
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;
worker_processes最多开启8个，8个以上性能提升不会再提升了，而且稳定性变得更低，所以8个进程够用了。
Nginx最多可以打开文件数
worker_rlimit_nofile 65535;
这个指令是指当一个nginx进程打开的最多文件描述符数目，理论值应该是最多打开文件数（ulimit -n）与nginx进程数相除，但是nginx分配请求并不是那么均匀，所以最好与ulimit -n的值保持一致。
注：
文件资源限制的配置可以在/etc/security/limits.conf设置，针对root/user等各个用户或者*代表所有用户来设置。
* soft nofile 65535
* hard nofile 65535
(3)开启高效传输模式

|
http {
include
mime.types;
default_type application/octet-stream;
……
sendfile on;
tcp_nopush on;
……
|
Include mime.types; //媒体类型,include 只是一个在当前文件中包含另一个文件内容的指令
default_type application/octet-stream; //默认媒体类型足够
sendfile on；//开启高效文件传输模式，sendfile指令指定nginx是否调用sendfile函数来输出文件，对于普通应用设为 on，如果用来进行下载等应用磁盘IO重负载应用，可设置为off，以平衡磁盘与网络I/O处理速度，降低系统的负载。
注意：如果图片显示不正常把这个改成off。
tcp_nopush on；必须在sendfile开启模式才有效，防止网路阻塞，积极的减少网络报文段的数量（将响应头和正文的开始部分一起发送，而不一个接一个的发送。）
(4)连接超时时间
主要目的是保护服务器资源，CPU，内存，控制连接数，因为建立连接也是需要消耗资源的

client_header_buffer_size 4k;
open_file_cache max=

inactive=20s;

open_file_cache_min_uses

;

;
client_body_timeout
15
;
reset_timedout_connection on;
send_timeout
15
;
server_tokens off;
client_max_body_size 10m;
|
keepalived_timeout客户端连接保持会话超时时间，超过这个时间，服务器断开这个链接
tcp_nodelay；也是防止网络阻塞，不过要包涵在keepalived参数才有效
client_header_buffer_size 4k;
客户端请求头部的缓冲区大小，这个可以根据你的系统分页大小来设置，一般一个请求头的大小不会超过 1k，不过由于一般系统分页都要大于1k，所以这里设置为分页大小。分页大小可以用命令getconf PAGESIZE取得。
open_file_cache max=102400 inactive=20s;
这个将为打开文件指定缓存，默认是没有启用的，max指定缓存数量，建议和打开文件
数一致，inactive 是指经过多长时间文件没被请求后删除缓存。
open_file_cache_valid 30s;
这个是指多长时间检查一次缓存的有效信息。
open_file_cache_min_uses 1;
open_file_cache指令中的inactive 参数时间内文件的最少使用次数，如果超过这个数字，文
件描述符一直是在缓存中打开的，如上例，如果有一个文件在inactive 时间内一次没被使用，它将被移除。
client_header_timeout设置请求头的超时时间。我们也可以把这个设置低些，如果超过这个时间没有发送任何数据，nginx将返回request time out的错误
client_body_timeout设置请求体的超时时间。我们也可以把这个设置低些，超过这个时间没有发送任何数据，和上面一样的错误提示
reset_timeout_connection 告诉nginx关闭不响应的客户端连接。这将会释放那个客户端所占有的内存空间。
send_timeout响应客户端超时时间，这个超时时间仅限于两个活动之间的时间，如果超过这个时间，客户端没有任何活动，nginx关闭连接
server_tokens 并不会让nginx执行的速度更快，但它可以关闭在错误页面中的nginx版本数字，这样对于安全性是有好处的。
client_max_body_size上传文件大小限制
(5)fastcgi调优

:

keys_zone=cache_fastcgi:128m inactive=1d max_size=10g;
|
fastcgi_connect_timeout 600; #指定连接到后端FastCGI的超时时间。
fastcgi_send_timeout 600; #向FastCGI传送请求的超时时间。
fastcgi_read_timeout 600; #指定接收FastCGI应答的超时时间。
fastcgi_buffer_size 64k; #指定读取FastCGI应答第一部分需要用多大的缓冲区，默认的缓冲区大小为fastcgi_buffers指令中的每块大小，可以将这个值设置更小。
总结：
nginx的缓存功能有：proxy_cache / fastcgi_cache
proxy_cache的作用是缓存后端服务器的内容，可能是任何内容，包括静态的和动态。
fastcgi_cache的作用是缓存fastcgi生成的内容，很多情况是php生成的动态的内容。
proxy_cache缓存减少了nginx与后端通信的次数，节省了传输时间和后端宽带。
fastcgi_cache缓存减少了nginx与php的通信的次数，更减轻了php和数据库(mysql)的压力。

执行sysctl -p使内核修改生效
(10)关于系统连接数的优化：
linux 默认值 open files为1024
#ulimit -n
1024
说明server只允许同时打开1024个文件
使用ulimit -a 可以查看当前系统的所有限制值，使用ulimit -n 可以查看当前的最大打开文件数。
新装的linux 默认只有1024 ，当作负载较大的服务器时，很容易遇到error: too many open files。因此，需要将其改大
在/etc/security/limits.conf最后增加：
* soft nofile 65535
* hard nofile 65535
* soft noproc 65535
* hard noproc 65535
二、部署LNMP

.
0
]# touch /tmp/xcache
[root@CXW xcache-
3.2
.
0
]# chmod
777
/tmp/xcache

|
[root@CXW xcache-
3.2
.
0
]# cp -r htdocs/ /usr/src/nginx1.
10
/html/xcache
|
4）配置php支持xcache
vi / etc/php.ini #编辑配置文件，在最后一行添加以下内容
[xcache-common]
extension = /usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/xcache.so
[xcache.admin]
xcache.admin.enable_auth = Off
[xcache]
xcache.shm_scheme ="mmap"
xcache.size=60M
xcache.count =1
xcache.slots =8K
xcache.ttl=0
xcache.gc_interval =0
xcache.var_size=64M
xcache.var_count =1
xcache.var_slots =8K
xcache.var_ttl=0
xcache.var_maxttl=0
xcache.var_gc_interval =300
xcache.test =Off
xcache.readonly_protection = Off
xcache.mmap_path ="/tmp/xcache"
xcache.coredump_directory =""
xcache.cacher =On
xcache.stat=On
xcache.optimizer =Off
[xcache.coverager]
