3.实验拓扑
注,实验拓扑见下文。
4.安装yum源
[root@nginx ~]# rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm [root@web1 ~]# rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm [root@web2 ~]# rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
[root@nginx ~]# ntpdate 202.120.2.101 [root@web1 ~]# ntpdate 202.120.2.101 [root@web2 ~]# ntpdate 202.120.2.101
6.关闭防火墙与SELinux5.各节点时间同步
[root@nginx ~]# service iptables stop [root@nginx ~]# chkconfig iptables off [root@nginx ~]# getenforce Disabled [root@web1 ~]# service iptables stop [root@web1 ~]# chkconfig iptables off [root@web1 ~]# getenforce Disabled [root@web2 ~]# service iptables stop [root@web2 ~]# chkconfig iptables off [root@web2 ~]# getenforce Disabled
1.解压三、安装Nginx
[root@nginx src]# tar xf nginx-1.4.2.tar.gz
[root@nginx src]# groupadd -g 108 -r nginx [root@nginx src]# useradd -u 108 -r -g 108 nginx [root@nginx src]# id nginx uid=108(nginx) gid=108(nginx) 组=108(nginx)
3.准备编译配置文件2.新建nginx用户与组
[root@nginx src]# yum install -y pcre-devel openssl-devel [root@nginx nginx-1.4.2]# ./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/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre
[root@nginx nginx-1.4.2]# make && make install
5.为nginx提供SysV init脚本4.编译并安装
[root@nginx ~]# cat /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
[root@nginx ~]# chmod +x /etc/init.d/nginx
7.添加至服务管理列表,并让其开机自动启动6.为此脚本赋予执行权限
[root@nginx ~]# chkconfig --add nginx [root@nginx ~]# chkconfig nginx on [root@nginx ~]# chkconfig nginx --list nginx
[root@nginx ~]# service nginx start 正在启动 nginx: [确定]
9.查看一下端口8.启动nginx
[root@nginx ~]# netstat -ntlp | grep :80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3889/nginx
10.测试一下
好了,Nginx安装与配置就到这里,下面我们来说一说Nginx的反向代理。
四、Nginx之反向代理
在配置nginx反向代理之间我们得先准备两台测试服务器,Web1与Web2。
1.安装httpd
[root@web1 ~]# yum install -y httpd [root@web2 ~]# yum install -y httpd
[root@web1 ~]# echo "web1.test.com" > /var/www/html/index.html [root@web2 ~]# echo "web2.test.com" > /var/www/html/index.htmlweb1.test.com web2.test.com
