Linux下Nginx安装教程
Linux下Nginx安装教程分享，具体内容如下
1、安装编译文件及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
2、安装PCRE，Nginx的rewrite的伪静态匹配规则需要用到正则表达式，PCRE就是起到这个作用。
下载地址：wgethttp://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
如果wget没有安装的话，需要先安装wget，yum -y install wget. wget是Linux环境下的下载工具。wget命令的使用见此文章
3、解压pcre安装包：tar -zxvf pcre-8.35.tar.gz
4、进入安装目录，编译安装
cd pcre-8.35
./configure
make && make install
5、查看pcre版本
pcre-config --version
6、下载Nginx
wgethttp://nginx.org/download/nginx-1.6.2.tar.gz
7、解压并进入安装包
8、编译安装
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
make
make install
9、查看Nginx版本
10、Nginx配置
1）、创建Nginx 运行使用的用户
/usr/sbin/groupadd www
/usr/sbin/useradd-g www www
2）、配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/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;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
#charset gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
#下面是server虚拟主机的配置
server
{
listen 80;#监听端口
server_name localhost;#域名
index index.html index.htm index.php;
root /usr/local/webserver/nginx/html;#站点目录
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;
# access_log off;
}
location ~ .*\.(js|css)?$
{
expires 15d;
# access_log off;
}
access_log off;
}
}
3）、检查nginx.conf配置文件的正确性
/usr/local/webserver/nginx/sbin/nginx -t
4）、关于Nginx连接数的配置，请参看网址：Nginx中worker connections问题的解决方法
