1.部署

1.添加nginx服务进程用户

# groupadd -r nginx

# useradd -r -g nginx nginx

2.下载源码包解压编译

可以在点击打开链接找到nginx对应版本

1.下载

# wget http://nginx.org/download/nginx-1.9.9.tar.gz

2.解压

# tar xvf nginx-1.9.9.tar.gz -C /usr/local/src

3.安装相应的开发工具

# yum groupinstall "Development tools"

# yum -y install gcc wget gcc-c++ automake autoconf libtool libxml2-devel libxslt-devel perl-devel perl-ExtUtils-Embed pcre-devel openssl-devel

4.进入nginx目录进行编译

# cd /usr/local/src/nginx-1.9.9/

# ./configure \

--prefix=/usr/local/nginx \

--sbin-path=/usr/sbin/nginx \

--conf-path=/etc/nginx/nginx.conf \

--error-log-path=/var/log/nginx/error.log \

--http-log-path=/var/log/nginx/access.log \

--pid-path=/var/run/nginx.pid \

--lock-path=/var/run/nginx.lock \

--http-client-body-temp-path=/var/tmp/nginx/client \

--http-proxy-temp-path=/var/tmp/nginx/proxy \

--http-fastcgi-temp-path=/var/tmp/nginx/fcgi \

--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \

--with-http_secure_link_module \

--with-http_stub_status_module \

--with-http_auth_request_module \

--with-mail \

--with-mail_ssl_module \

--with-file-aio \

--with-ipv6 \

--with-http_v2_module \

--with-threads \

--with-stream \

--with-stream_ssl_module

5.完成编译

# make && make install

# mkdir -pv /var/tmp/nginx/client

6.添加SysV启动脚本

1.创建文件

# vim /etc/init.d/nginx

2.按i进入编辑状态

#!/bin/sh

#

# nginx - this script starts and stops the nginx daemon

#

# chkconfig: - 85 15

# description: Nginx is an HTTP(S) server, HTTP(S) reverse \

# proxy and IMAP/POP3 proxy server

# processname: nginx

# config: /etc/nginx/nginx.conf

# config: /etc/sysconfig/nginx

# pidfile: /var/run/nginx.pid

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/sbin/nginx"

prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

start() {

[ -x $nginx ] || exit 5

[ -f $NGINX_CONF_FILE ] || exit 6

echo -n #34;Starting $prog: "

daemon $nginx -c $NGINX_CONF_FILE

retval=$?

echo

[ $retval -eq 0 ] && touch $lockfile

return $retval

}

stop() {

echo -n #34;Stopping $prog: "

killproc $prog -QUIT

retval=$?

echo

[ $retval -eq 0 ] && rm -f $lockfile

return $retval

killall -9 nginx

}

restart() {

configtest || return $?

stop

sleep 1

start

}

reload() {

configtest || return $?

echo -n #34;Reloading $prog: "

killproc $nginx -HUP

RETVAL=$?

echo

}

force_reload() {

restart

}

configtest() {

$nginx -t -c $NGINX_CONF_FILE

}

rh_status() {

status $prog

}

rh_status_q() {

rh_status >/dev/null 2>&1

}

case "$1" in

exit 2

esac

7.赋予脚本执行权限

# chmod +x /etc/init.d/nginx

8.添加至服务管理列表，设置开机自启

# chkconfig --add nginx

# chkconfig nginx on

9.启动

# service nginx start

10.查看运行情况

# netstat -tnlp

2.配置项

更多参数帮助可以在nginx目录下执行如下命令查看

# ./configure --help

3.nginx.conf配置

#user nobody;

worker_processes 1; #工作进程：数目。根据硬件调整，通常等于cpu数量或者2倍cpu数量。

#错误日志存放路径

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid; # nginx进程pid存放路径

events {

worker_connections 1024; # 工作进程的最大连接数量

}

http {

include mime.types; #指定mime类型，由mime.type来定义

default_type application/octet-stream;

# 日志格式设置

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

# '$status $body_bytes_sent "$http_referer" '

# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main; #用log_format指令设置日志格式后，需要用access_log来指定日志文件存放路径

sendfile on; #指定nginx是否调用sendfile函数来输出文件，对于普通应用，必须设置on。

如果用来进行下载等应用磁盘io重负载应用，可设置off，以平衡磁盘与网络io处理速度，降低系统uptime。

#tcp_nopush on; #此选项允许或禁止使用socket的TCP_CORK的选项，此选项仅在sendfile的时候使用

#keepalive_timeout 0; #keepalive超时时间

keepalive_timeout 65;

#gzip on; #开启gzip压缩服务

#虚拟主机

server {

listen 80; #配置监听端口号

server_name localhost; #配置访问域名，域名可以有多个，用空格隔开

#charset koi8-r; #字符集设置

#access_log logs/host.access.log main;
