# yum -y groupinstall "Development Tools"
# yum -y install pcre-devel
2、创建运行nginx服务的用户组
# groupadd -r nginx
# useradd -r -g nginx nginx
3、接着开始编译和安装：
# tar -xf nginx-1.9.4.tar.gz
# cd nginx-1.9.4
# ./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
# make && make install
说明：如果想使用nginx的perl模块，可以通过为configure脚本添加--with-http_perl_module选项来实现，但目前此模块仍处于实验性使用阶段，可能会在运行中出现意外，因此，其实现方式这里不再介绍。如果想使用基于nginx的cgi功能，也可以基于FCGI来实现，具体实现方法请参照网上的文档。
4、为nginx提供服务init脚本:
新建文件/etc/rc.d/init.d/nginx，内容如下：
#!/bin/bash
#
# 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
5、而后为此脚本赋予执行权限：
# chmod +x /etc/rc.d/init.d/nginx
添加至服务管理列表，并让其开机自动启动：
# chkconfig --add nginx
# chkconfig nginx on
6、实现一个简单的重定向
server {
listen 80;
server_name localhost;
location ~* ^/forum { //在18.179网站根目录存在forum
proxy_pass http://192.168.18.179; //重定向到18.179上
proxy_set_header X-Real-IP $remote_addr; //access日志中ip源地址转发
}
}
7、另一个重定向的例子
location /yy/ {
proxy_pass http://192.168.18.179/wordpress/;
proxy_set_header X-Real-IP $remote_addr;
}
8、实现负载均衡
upstream websrvs { //负载均衡的模块
server 192.168.18.178 weight=1 max_fails=2 fail_timeout=2;//权重1，2次请求，2s超时
server 192.168.18.179 weight=1 max_fails=2 fail_timeout=2;
}
proxy_cache_path /nginx/cache/first levels=1:2:1 keys_zone=first:20m max_size=1G;
//上面是网站缓存模块，定义一个名为first的缓存，其内存占用为20m，磁盘空间占用为1G
server {
listen 80;
server_name localhost;
#charset koi8-r;
add_header X-Via $server_addr;
add_header X-Cache $upstream_cache_status; //缓存可显示在浏览器调试中
#access_log logs/host.access.log main;
#location / {
# root html;
# index index.php index.html index.htm;
#
}
location / {
proxy_pass http://websrvs/; //调用上面的websrvs
proxy_set_header X-Real-IP $remote_addr;
# proxy_cache first; //调用定义的缓存
# proxy_cache_valid any 1m; //所有页面缓存1分钟
}
}
访问页面的时候轮询
