nginx下载安装和配置

一.安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel

二.首先安装pcre
pcre作用是让nginx支持Rewrite功能
1.下载安装包
wget https://www.wendangku.net/doc/5710632713.html,/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2.解压安装包
tar zxvf pcre-8.35.tar.gz
3.进入安装目录
cd pcre-8.35
4.编译安装
./configure
make && make install
5.查看pcre版本
pcre-config --version

安装Nginx
1.下载nginx
wget https://www.wendangku.net/doc/5710632713.html,/download/nginx-1.6.2.tar.gz
2.解压安装包
tar zxvf nginx-1.6.2.tar.gz
3.进入安装包目录
cd nginx-1.6.2
4.编译安装
./configure --prefix=/usr/installpackage/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/installpackage/pcre-8.35
make
make install
5.查看nginx版本
/usr/installpackage/nginx/sbin/nginx -v
到此nginx安装完成.....

Nginx配置
创建Nginx运行使用的用户www:
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www

配置nginx.conf ，将/usr/installpackage/nginx/conf/nginx.conf替换为以下内容
cat /usr/installpackage/nginx/conf/nginx.conf #查看原来的nginx.conf配置信息

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/installpackage/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/installpackage/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;

'$status $body_bytes_sent "$http_referer" '

}

}

检查配置文件ngnix.conf的正确性命令：
/usr/local/webserver/nginx/sbin/nginx -t
如果提示successful,则表示配置成功

启动nginx
/usr/installpackage/nginx/sbin/nginx
或者
cd /usr/installpackage/nginx/sbin/
./nginx

Nginx其他常用命令:
/usr/installpackage/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/installpackage/nginx/sbin/nginx -s reopen # 重启 Nginx
/usr/installpackage/nginx/sbin/nginx -s stop # 停止 Nginx
