centos7.0 64位系统安装 nginx

1 下载nginx

从nginx官网 http://nginx.org/ 下载新的稳定版本nginx 并上传到linux服务器

2 安装nginx 所需要的扩展

yum -y install pcre openssl  openssl-devel

3 安装nginx

useradd -s /sbin/nologin www
tar zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --without-http-cache --with-http_ssl_module  --with-pcre=/home/www/pcre-8.31 (源文件的解压路径不是安装路径)
--with-http_gzip_static_module
make
make install

配置nginx开机启动文件

vi /etc/init.d/nginx 写入如下内容 根据实际情况修改

#!/bin/sh
#
# nginx - this script start and stop the nginx daemon
#
# chkconfig: 2345 55 25
# description: Startup script for nginx
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /var/run/nginx.pid
#
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

DAEMON=/usr/local/nginx/sbin/nginx
CONFIGFILE=/usr/local/nginx/conf/nginx.conf
PIDFILE=/var/run/nginx.pid
SCRIPTNAME=/etc/init.d/nginx
LOCKFILE=/var/lock/nginx.lock

set -e
[[ -x "$DAEMON" ]] || exit 0

start() {
echo "Startting Nginx......"
[[ -x $DAEMON ]] || exit 5
[[ -f $CONFIGFILE ]] || exit 6
$DAEMON -c $CONFIGFILE || echo -n "Nginx already running!"
[[ $? -eq 0 ]] && touch $LOCKFILE
}

stop() {
echo "Stopping Nginx......"
MPID=`ps aux | grep nginx | awk '/master/{print $2}'`

if [[ "${MPID}X" != "X" ]]; then
kill -QUIT $MPID
[[ $? -eq 0 ]] && rm -f $LOCKFILE
else
echo "Nginx server is not running!"
fi
}

reload() {
echo "Reloading Nginx......"
MPID=`ps aux | grep nginx | awk '/master/{print $2}'`

if [[ "${MPID}X" != "X" ]]; then
kill -HUP $MPID
else
echo "Nginx can't reload!"
fi
}

case "$1" in
start)
start
;;

stop)
stop
;;

reload)
reload
;;

restart)
stop
sleep 1
start
;;

*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}"
exit 3
;;
esac

exit 0

4 设置开机启动

　　　　　　　　chmod 755 /etc/init.d/nginx
chkconfig --add nginx
chkconfig  nginx on
/etc/init.d/nginx start

5 测试 用浏览器访问实际的域名 看看是否正常

6 重启服务器 看nginx 是否随机启动

7 配置相关

######## 查看nginx状态配置
location =/nginx_status {
stub_status on;
access_log off;
#allow 127.0.0.1;
#deny all;
}

active connections – 活跃的连接数量
server accepts handled requests — 总共处理了11989个连接 , 成功创建11989次握手, 总共处理了11991个请求
reading — 读取客户端的连接数.
writing — 响应数据到客户端的数量
waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
