安装nginx

 

如果机器上有Apache在运行  可以先把Apache关掉  或者准备让nginx监听其他端口

systemctl stop httpd

 

nginx下载地址
http://nginx.org/en/download.html

Mainline version 开发版
Stable version 稳定版
Legacy versions 历史版

鼠标移动到你要选择的版本超链接上点右键 复制链接地址

 

进入Linux终端

cd  /usr/local

 

用wget命令跟上复制的链接地址

wget http://nginx.org/download/nginx-1.12.2.tar.gz

 

解压

tar -zxvf nginx-1.12.2.tar.gz

 

进入目录

cd nginx-1.12.2

 

配置

./configure

 

如果报错 报什么安装什么

报错: the HTTP rewrite module requires the PCRE library.
解决：yum -y install pcre-devel

报错：the HTTP gzip module requires the zlib library
解决：yum install -y zlib-devel

报错：the HTTP cache module requires md5 functions from OpenSSL library
解决：yum -y install openssl openssl-devel

编译安装

make && make install

 

安装完成后查找nginx路径

whereis nginx 

 

打开配置文件

vim /usr/local/nginx/conf/nginx.conf

#这一段都是包在server{}之中  如要配置多个域名 则复制粘贴多个server{}代码块
server {
    listen       80;
    server_name  www.fengyumeng.cn fengyumeng.cn;
    root /var/www/admin;
    location / {
        #重写url隐藏index.php
            if (!-e $request_filename) {
                 rewrite ^/index.php(.*)$ /index.php?s=$1 last;
                 rewrite ^(.*)$ /index.php?s=$1 last;
             }
        index  index.html index.htm index.php;
    }
    #把下面这一段打开注释 并将其中的/scripts 修改为 $document_root
    location ~ .php$ {
        root           /var/www/admin;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

}

 若要显示目录列表 可在外层的http代码块中添加这行配置

autoindex on;

配置php-fpm

vim /usr/local/php7/etc/php-fpm.d/www.conf

 

把里面的user group 两行 改为nobody 或者是系统中存在的用户

user = nobody
group = nobody

 

运行fpm 载入php.ini

/usr/local/php7/sbin/php-fpm -c /usr/local/php7/etc/php.ini

 

注意  如果修改了php.ini则每次需要杀掉php-fpm进程再重新启动php-fpm

ps -ef | grep php-fpm
kill -9 ***

 

nginx一般命令

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf  //启动
/usr/local/nginx/sbin/nginx -s stop     //强制停止
/usr/local/nginx/sbin/nginx -s quit     //安全停止
/usr/local/nginx/sbin/nginx -s reload   //平滑重启
ps -aux | grep nginx                    //查询进程

 

启动后 用浏览器输入服务器ip 回车 便可看到nginx默认欢迎页面

 

编写服务脚本

vim /etc/init.d/nginx

 

粘贴以下代码  注意路径

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /usr/local/nginx/logs/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/usr/local/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "${NETWORKING}" = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
   echo "nginx already running...."
   exit 1
fi
   echo -n $"Starting $prog: "
   daemon $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo
}
# See how we were called.
case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;
status)
        status $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

 

设置权限

chmod 755 /etc/init.d/nginx  

 

加入自启动

vi /etc/rc.local

增加一行 /usr/local/nginx/sbin/nginx

 

此时将nginx停止

/usr/local/nginx/sbin/nginx -s quit

 

换用服务命令启动

/etc/init.d/nginx start

 

#查询服务是否开机启动
systemctl is-enabled httpd

#将Apache移出开机启动项
systemctl disable httpd

#将nginx加入开机启动
chkconfig nginx on

 

#服务命令
systemctl status nginx
systemctl start nginx
systemctl stop nginx
systemctl reload nginx
systemctl restart nginx
