nginx的安装与配置
1.yum groupinstall " Development Tools" " Development Libraries" -y//安装这两个开发组后，后面的编译就不会出错了
2.groupadd nginx
useradd -g nginx -s /bin/false -M nginx//增加一个nginx用户和用户组，且不为该用户创建家目录
3.编译安装：
tar xf nginx-1.1.3.tar.gz
cd nginx-1.1.3
./configure \
--prefix=/usr \
--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/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--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/ \
--with-pcre
make && make install
4.自己编写一个/etc/init.d/nginx启动脚本
这里给出脚本内容：#!/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
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
$1
;;
restart|configtest)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;
status)
rh_status
;;
condrestart|try-restart)
rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
这里不要忘记给该脚本执行权限，并加到启动队列中、
chmod +x nginx
service nginx start
5.netstat -tnlp查看80端口是否启动
简单说明：pcre-devel必须安装，用来支持正则表达式
index表示查找网页的先后顺序
/etc/init.d/nginx configtest//检查语法是否错误
6.nginx的认证：yum install -y httpd
chkconfig httpd off
touch /etc/nginx/htpasswd
htpasswd -cd /etc/nginx/htpasswd tom //添加用户
vim /etc/nginx/nginx.conf
location / {
root /web;
auth_basic “You need a key” #提示语
auth_basic_user_file /etc/nginx/htpasswd #指定读取的授权文件路径
index index.html index.htm;
}
7.实现反向代理：负载均衡
http {
upstream myproject
{
server 172.16.100.11:80 weight=3;
server 172.16.100.12:80;
}
server {
listen 80;
server_name www.a.com;
location / {
proxy_pass http://myproject;
}
}
}
8.实现虚拟主机
http {
server {
listen 80;
server_name www.a.com;
access_log logs/a.access.log main;
index index.html;
root /var/www/a.com/htdocs;
}
server {
listen 80;
server_name www.b.com;
access_log logs/b.access.log main;
index index.html;
root /var/www/b.com/htdocs;
}
}
