2、Nginx服务器的安装与配置

1、 Nginx的下载

可以从以下网络连接进行下载nginx的不同版本：

http://nginx.org/download/

2、 Nginx的安装

Nginx分为windows和linux下的安装，本文以linux版本Centos为例，其余linux发行版本都大致相同，进行Nginx的源码编译安装，假如有想理解windows安装的，请自行网上查询，也可以私聊我。

2.1、用上传工具将Nginx上传到Centos内。

2.2、安装Nginx的依赖软件

yum install gcc openssl-devel pcre-devel zlib-devel

2.3、创立nginx使用户

#groupadd –r nginx

#useradd -r -g nginx -s /bin/false -M nginx

2.4、编译安装

#./configure \

–prefix=/usr/local \ 指定安装路径

–sbin-path=/usr/sbin/nginx \ 指定Nginx可执行文件安装路径

–conf-path=/etc/nginx/nginx.conf \指定nginx.conf文件的路径

–error-log-path=/var/log/nginx/error.log \指定error.log文件的路径

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

–pid-path=/var/run/nginx/nginx.pid \指定pd指令的路径

–lock-path=/var/lock/nginx.lock \

–user=nginx \指定Nginx的使用户为nginx

–group=nginx \指定Nginx的所属组为nginx

–with-http_ssl_module \打开用HTTP SSL板块

–with-http_flv_module \

–with-http_stub_status_module \

–with-http_gzip_static_module \

–http-client-body-temp-path=/var/tmp/nginx/client/ \ 指定http用户端请求缓存文件存放目录的路径。

–http-proxy-temp-path=/var/tmp/nginx/proxy/ \ 指定http反向代理商缓存文件存放目录的路径

–http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \指定http fastCGI缓存文件存放目录的路径。

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

–http-scgi-temp-path=/var/tmp/nginx/scgi \

–with-pcre打开pcre库的用

表示编译成功

# make && make install

注：

关于配置选项的简单说明：

–prefix= – The path relative to which all other Nginx paths will resolve. If not specified, defaults to /usr/local/nginx.

–sbin-path= – The path to the nginx executable. Only used for installation. If not specified defaults to /sbin/nginx.

–conf-path= – The default location of nginx.conf if no -c parameter is provided. If not provided, defaults to /conf/nginx.conf.

–pid-path= – The path to nginx.pid, if not set via the “pid” directive in nginx.conf. If not provided, defaults to /logs/nginx.pid.

–error-log-path= – The location of the error log if not set via the “error_log” in nginx.conf. If not set, defaults to /logs/error.log.

–http-log-path= – The location of the access log if not set via the “access_log” directive in nginx.conf. If not set, defaults to /logs/access.log.

–user= – The default user that nginx will run as if not set in nginx.conf via the “user” directive. If not set, defaults to “nobody”.

–group= – The default group that nginx will run under if not set via the “user” directive in nginx.conf. If not set defaults to “nobody”.

–with-http_ssl_module – Enable ngx_http_ssl_module. Enables SSL support and the ability to handle HTTPS requests. Requires OpenSSL. On Debian, this is libssl-dev.

–with-http_flv_module – Enable ngx_http_flv_module

–http-client-body-temp-path=PATH – Set path to the http client request body temporary files. If not set, defaults to /client_body_temp

–http-proxy-temp-path=PATH – Set path to the http proxy temporary files. If not set, defaults to /proxy_temp

–http-fastcgi-temp-path=PATH – Set path to the http fastcgi temporary files. If not set, defaults to /fastcgi_temp

–lock-path= – The path to the nginx.lock file. If not provided, defaults to /logs/nginx.lock.

3、 将以下存放在/etc/rc.d/init.d/目录下，并命名为nginx（或者者其余的，你自己记得住就可），即可以用servie服务进行Nginx开启、关闭、重启。

#!/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

# 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

make_dirs() {

# make required directories

user=`nginx -V 2>&1 | grep “configure arguments:” | sed 's/[^*]*–user=\([^ ]*\).*/\1/g' -`

options=`$nginx -V 2>&1 | grep 'configure arguments:'`

for opt in $options; do

if [ `echo $opt | grep '.*-temp-path'` ]; then

value=`echo $opt | cut -d “=” -f 2`

if [ ! -d “$value” ]; then

# echo “creating” $value

mkdir -p $value && chown -R $user $value

fi

fi

done

}

start() {

[ -x $nginx ] || exit 5

[ -f $NGINX_CONF_FILE ] || exit 6

make_dirs

echo -n $”Starting $prog: “

daemon $nginx -c $NGINX_CONF_FILE

retval=$?

echo

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

return $retval

}

stop() {

echo -n $”Stopping $prog: “

killproc $prog -QUIT

retval=$?

echo

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

return $retval

}

restart() {

configtest || return $?

stop

sleep 1

start

}

reload() {

configtest || return $?

echo -n $”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

start)

rh_status_q && exit 0

$1

stop)

rh_status_q || exit 0

rh_status_q || exit 0

;;

*)

echo $”Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}”

exit 2

esac

4、 测试。

/usr/local/nginx/sbin启动nginx

Service nginx start ，而后执行netstat –tunlp ，查看能否有80端口开放，此时Nginx就编译安装成功。

注：需要关闭防火墙和selinux
