Nginx简单的安装排错

安装 nginx 所需要的pcre库即：perl 兼容正则表达式

yum install pcre pcre-devel -y

       rpm -qa pcre pcre-devel
       检查是否安装好pcre-devel，openssl-devel，
       rpm -qa pcre-devel pcre
       [root@kingle0001 ~]# rpm -qa openssl-devel openssl
                             openssl-devel-1.0.1e-57.el6.x86_64
                             openssl-1.0.1e-57.el6.x86_64

       rpm -qa openssl-devel openssl
       [root@kingle0001 ~]# rpm -qa openssl-devel openssl
                           openssl-1.0.1e-57.el6.x86_64 少了一个
       [root@jinc1 nginx-1.15.1]# yum install openssl-devel openssl --下载一下

开始安装Nginx

       下载：wget -q http://nginx.org/download/nginx-1.15.1.tar.gz

       useradd nginx -s /sbin/nologin -M

       tar -zxvf nginx-1.6.3.tar.gz

       cd nginx-1.15.1

       ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.15.1/ --with-http_stub_status_module --with-http_ssl_module

       make

       make install

       ln -s /application/nginx-1.15.1 /application/nginx/

       /application/nginx/ --该文件夹为自己创建

启动： /application/nginx/nginx-1.15.1/sbin/nginx

进不去欢迎界面解决方法
关闭selinux
           setenforce 0 临时关闭
           永久关闭编辑文件/etc/selinux/config
关闭防火墙
           /etc/init.d/iptables stop 关闭防火墙

           chkconfig iptables off 开机自启关闭

           /etc/init.d/iptabes status 查看防火墙当前状态

查看80端口信息 netstat -lnt|grep 80

查看nginx进程 ps-ef|grep nginx

查看nginx的错误日志 cat /application/nginx/nginx-1.15.1/error.log

ping 10.0.0.200 看是否连通

wegt 10.0.0.200 或者curl -I 10.0.0.200 模拟用户

一个小坑

[root@jinc2 nginx]# ./sbin/nginx -s reload
nginx: [error] invalid PID number "" in "/lnmp/nginx-1.15.1//logs/nginx.pid"

今天偶然出现了这个错误，问了一下百度大神，，都说是因为是加载配置文件报的错，所以用-c 选项指定配置文件
     [root@jinc2 nginx]# ./sbin/nginx -c /lnmp/nginx-1.15.1//conf/nginx.conf
     nginx: [emerg] bind() to 10.0.0.100:80 failed (98: Address already in use)
     nginx: [emerg] bind() to 10.0.0.101:80 failed (98: Address already in use)
     nginx: [emerg] bind() to 10.0.0.102:80 failed (98: Address already in use)
     nginx: [emerg] bind() to 10.0.0.100:80 failed (98: Address already in use)
     nginx: [emerg] bind() to 10.0.0.101:80 failed (98: Address already in use)
     nginx: [emerg] bind() to 10.0.0.102:80 failed (98: Address already in use)
     [root@jinc2 nginx]# ./sbin/nginx -s reload
     nginx: [error] invalid PID number "" in "/lnmp/nginx-1.15.1//logs/nginx.pid"
按照网上的思路试了一遍，发现并没有什么用，然后，仔细看了一下错误，大概意思是无效的pid，在lnmp/nginx-1.15.1//logs/nginx.pid 这个文件中，于是，打开这个文件看了一下。。。怎么什么都没有。。有点蒙蔽。继续。。去另一台看了一下
     [root@jinc1 conf]# cat /application/nginx/nginx-1.15.1/logs/nginx.pid
     7104
原来并不是空的，然后，在另一台继续查了一下他的pid
      [root@jinc1 conf]# ps -ef | grep nginx
      root       7104      1 0 03:30 ?        00:00:00 nginx: master process ../sbin/nginx
哇哇哇，原来如此，，，回到本机，查看pid

     [root@jinc2 nginx]# ps -ef |grep nginx
     root       9862      1 0 03:21 ?        00:00:00 nginx: master process ./sbin/nginx
现在好办了，加进去试试
     [root@jinc2 nginx]# echo 9862 > /lnmp/nginx/logs/nginx.pid
     [root@jinc2 nginx]# ./sbin/nginx -s reload
     [root@jinc2 nginx]#
已经ok了，nice
