LNMP环境搭建之nginx安装

下载nginx

cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.1.tar.gz

解压

tar zxf nginx-1.12.1.tar.gz

编译

./configure --prefix=/usr/local/nginx
make &&  make install

做一个nginx启动脚本

vim /etc/init.d/nginx
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start() {
       echo -n $"Starting $prog: "
       mkdir -p /dev/shm/nginx_temp
       daemon $NGINX_SBIN -c $NGINX_CONF
       RETVAL=$?
       echo
       return $RETVAL
}

stop() {
       echo -n $"Stopping $prog: "
       killproc -p $NGINX_PID $NGINX_SBIN -TERM
       rm -rf /dev/shm/nginx_temp
       RETVAL=$?
       echo
       return $RETVAL
}

reload(){
       echo -n $"Reloading $prog: "
       killproc -p $NGINX_PID $NGINX_SBIN -HUP
       RETVAL=$?
       echo
       return $RETVAL
}

restart(){
       stop
       start
}

configtest(){
   $NGINX_SBIN -c $NGINX_CONF -t
   return 0
}

case "$1" in
 start)
       start
       ;;
 stop)
       stop
       ;;
 reload)
       reload
       ;;
 restart)
       restart
       ;;
 configtest)
       configtest
       ;;
 *)
       echo $"Usage: $0 {start|stop|reload|restart|configtest}"
       RETVAL=1
esac

exit $RETVAL

给755权限并加入开机启动

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

编辑nginx配置文件

cd /usr/local/nginx/conf/
mv nginx.conf nginx.conf.bak
vim nginx.conf

            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;

    }

检查配置文件有没有错误

 /usr/local/nginx/sbin/nginx -t

启动

/etc/init.d/nginx  start

监听端口

netstat -lntp |grep 80

启动报错

错误
Restarting nginx (via systemctl):  Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
解决办法：
原因是这一句写分开了
gzip_types text/plain application/x-javascript text/css text/htm 
    application/xml;

curl测试解析php

curl localhost
//这个页面就是server里面定义的网站根目录下/usr/local/nginx/html的index.php文件

LNMP之所以能够解析php是因为有下面一段配置
location ~ \.php$
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;    (nginx通过这一行调用php-fpme服务)
           #fastcgi_pass 127.0.0.1:9000;  
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }
