Nginx编译安装与负载压力测试

安装编译器及相关的工具

[root@localhost softs]# yum install gcc gcc-c++ autoconf automake -y

模块依赖性：nginx的一些模块需要第三方库的支持，gzip需要libzip库，rewrite需要pcre库，ssl需要libssl库等，可以使用yum安装来解决这些依赖库。

[root@localhost ~]# yum install zlib zlib-devel openssl openssl-devel pcre pcre-devel  -y 

===========>安装过程所需的一些开发包和支持包 

安装pcre-8.33.tar.gz     ======> perl语言兼容正则表达式

[root@localhost pcre-8.33]# ./configure --enable-utf8 --enable-rebuild-chartables --enable-newline-is-any --enable-pcregrep-libz  && make  && make install

安装nginx

[root@localhost nginx-1.5.6]# yum install gd gd-devel libxml2 libxml2-devel 

===========>安装gd，libxml库与开发包

[root@localhost nginx-1.5.6]# ./configure --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --user=nginx --group=nginx --with-rtsig_module --with-select_module --with-poll_module --with-http_ssl_module --with-http_realip_module  --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_sub_module --with-http_dav_module --with-http_gzip_static_module --with-http_flv_module --with-http_perl_module --with-perl=/usr/bin/perl --http-log-path=/var/log/nginx/access.log --with-pcre --with-pcre=/usr/src/lnmp/pcre-8.33/  --with-http_stub_status_module

[root@localhost nginx-1.5.6]#  make  

[root@localhost nginx-1.5.6]#  make install

修改nginx的配置文件

[root@localhost nginx-1.5.6]#   vi /usr/local/nginx/conf/nginx.conf

user  nginx;    ####指定nginx的默认用户
worker_processes  1;####启动进程,通常设置成和cpu的数量相等

error_log  /var/log/nginx/error.log;      ####nginx的错误日志存放目录
#error_log  logs/error.log  notice;
error_log  /var/log/nginx/error.log  info;      ####nginx的错误日志级别设置

pid        /var/run/nginx/nginx.pid;####nginx运行进程pid

events {
    worker_connections  1024;              #####单个后台worker process进程的最大并发链接数
}

http {
    include       mime.types;    #######设定mime类型,类型由mime.type文件定义
    default_type  application/octet-stream;
###MIME类型就是设定某种扩展名的文件用一种应用程序来打开的方式类型，当该扩展名文件被访问的时候，浏览器会自动使用指定应用程序来打开

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '                      '$status $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';
=========>指定日志的格式

    access_log  /var/log/nginx/access.log  main;       ###日志目录

    sendfile        on;      ####sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，必须设为 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uptime.

    gzip  on;         #####开启zip压缩

    server {
        listen       80;           server_name  localhost;
        root /www;       ####DocumentRoot
        index  index.html index.htm index.php;      ####支持的索引类型
        charset gb2312;####支持的语言

        location / {                try_files $uri $uri/ /index.php;    

        }

####按顺序检查文件是否存在，返回第一个找到的文件。结尾的斜线表示为文件夹 -$uri/。如果所有的文件都找不到，会进行一个内部重定向到最后一个参数
        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass   127.0.0.1:9000;
            include        fastcgi.conf;
        }

}

[root@localhost conf]# mkdir /www     ####创建相应的目录

[root@localhost conf]# chown nginx.nginx /www/    ####改属组和属主

[root@localhost ~]# mv /usr/local/nginx/html/* /www    ###将nginx默认的index.html移动到自己指定的目录也可自己建

[root@localhost html]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf   #####启动nginx

浏览器访问127.0.0.1

http://127.0.0.1/index.html

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
