由於nginx在做靜態網頁的時候有着apache無法匹敵的性能,所以在下面主要從淺到深依次講述他的作用:
一、編譯安裝nginx
1.初始化環境變量:
#yum groupinstall "Development Libraries"
#yum install gcc openssl-devel pcre-devel zlib-devel
2.編譯安裝nginx
#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 上一篇博客裏面對裏面的安裝參數進行過詳細的介紹,這裏就不再細說了
3.編寫nginx啓動腳本:
#vim /etc/init.d/nginx
#!/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: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
#chmod +x !$
4.啓動nginx服務
#service nginx start
在瀏覽其中輸入http://192.168.0.78測試如下圖所示:
1.基於端口的虛擬主機訪問
根據上面的安裝的過程,我們知道網頁存放的位置在/usr/html下,所以我這裏爲了區分,就分別使用index.html和test.html兩個網頁進行測試
裏面的內容分別是nginx virtual one和nginx virtual two
現在前面的準備工作已經完成,接下來就是配置/etc/nginx/nginx.conf文件了
其他的默認不變,在http{..} 中添加兩個server就行了,同時指定兩個監聽端口,我的配置如下所示:
server {
listen 8080; //端口不同
server_name localhost;
location / {
root html;
index test.html;
}
}
server {
listen 80; //端口不同
server_name localhost;
location / {
root html;
index index.html;
}
}
#service nginx reload //重新載入配置文件
在瀏覽器中輸入http://192.168.0.78和 http://192.168.0.78:8080分別如下圖所示:
#vim /etc/nginx/nginx.conf
server {
listen 80;
server_name 192.168.0.78; //IP不同
location / {
root html;
index test.html;
}
}
server {
listen 80;
server_name 192.168.0.83; //IP不同
location / {
root html;
index index.html;
}
}
我的網卡的配置
#ifconfig eth0 192.168.0.78
#ifconfig eth0:0 192.168.0.83
下面分別在瀏覽其中輸入http://192.168.0.78和http://192.168.0.83,結果如下圖所示
#vim /etc/nginx/nginx.conf
server {
listen 80;
server_name node1.luowei.com; //主機名不同
location / {
root html;
index test.html;
}
}
server {
listen 80;
server_name node2.luowei.com; //主機名不同
location / {
root html;
index index.html;
}
}
在瀏覽器中輸入http://node1.luowei.com和http://node2.luowei.com,測試如下圖所示
