阿里云centOS下LNMP搭建

2,264 阅读5分钟

公司新买了个阿里云专门给小程序用,已经装了centOS,我再装下环境,记录下。 时间 2018年5月3日

1查看服务器信息

我得到了ip 用户名和密码 putty登陆 看了下 40G+2G centOS6.3 nginx之类的没有装

2.安装第三方yum源

wget http://www.atomicorp.com/installers/atomic  #下载
sh ./atomic  #安装
yum check-update  #更新yum源
2.1如果不能用wget,那么先要安装wget
yum -y install wget
2.2 如果出现Permission denied

改下权限

chmod 777 atomic

3和4被吃了 所以直接5

5.安装nginx

yum remove httpd* php* #删除系统自带的软件包
yum install nginx #安装nginx 根据提示输入y进行安装
chkconfig nginx on #设置nginx开机启动
service nginx start #启动nginx
# yum install nginx

Complete!

如果发现端口占用,一般有两种常见情况 1.是nginx的ipv6 bug, 2.是其他程序端口占用 我这次遇到的是httpd占用 ipv6的情况见下文 8.1


# netstat -ntpl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      1415/httpd
tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      1422/vsftpd
tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      1017/sshd
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      1389/mysqld
tcp        0      0 :::22                       :::*                        LISTEN      1017/sshd
# kill 1415
# service nginx start
Starting nginx:                                            [  OK  ]

此时浏览器中查看你的网站 应该能看到nginx的欢迎界面

6.安装MySQL

yum install mysql mysql-server #输入Y即可自动安装,直到安装完成
/etc/init.d/mysqld start #启动MySQL
chkconfig mysqld on #设为开机启动
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf #拷贝配置文件(注意:如果/etc目录下面默认有一个my.cnf,直接覆盖即可)
为root账户设置密码
mysql_secure_installation 回车,根据提示输入,输入2次密码,回车,根据提示一路输入Y,最后出现:Thanks for using MySQL!
MySql密码设置完成,重新启动 MySQL:
/etc/init.d/mysqld restart #重启
/etc/init.d/mysqld stop #停止
/etc/init.d/mysqld start #启动

然后我遇到了一些问题,因为这个服务器上装过mysql 我删了重装, 启动失败了,查了资料参照这个解决了 Linux下重新安装MySql后出现'MySQL Daemon failed to start‘解决方法

7.安装PHP5

yum install php php-fpm #根据提示输入Y直到安装完成
安装PHP组件,使PHP5支持MySQL
yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt #这里选择以上安装包进行安装,根据提示输入Y回车
chkconfig php-fpm on #设置php-fpm开机启动
/etc/init.d/php-fpm start #启动php-fpm

8.配置nginx支持php

cp /etc/nginx/nginx.conf /etc/nginx/nginx.confbak  #备份原有配置文件
vi /etc/nginx/nginx.conf  #编辑
user nginx nginx; #修改nginx运行账号为:nginx组的nginx用户
:wq #保存退出
cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.confbak #备份原有配置文件
vi /etc/nginx/conf.d/default.conf #编辑
index index.php index.html index.htm; #增加index.php
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
#取消FastCGI server部分location的注释,并要注意fastcgi_param行的参数,改为$document_root$fastcgi_script_name,或者使用绝对路径
service nginx restart #重启nginx
8.1可能出现修改nginx配置文件后,重启报错:

nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol) 解决办法:

vim /etc/nginx/conf.d/default.conf

listen       80 default_server;
listen       [::]:80 default_server;

改为:

listen       80;
#listen      [::]:80 default_server;

重新启动nginx即可

9.php配置

vi /etc/php.ini #编辑
date.timezone = PRC #把前面的分号去掉,改为date.timezone = PRC
disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd,posix_getegid,posix_geteuid,posix_getgid,posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid,posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty,posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid,posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname
#在386行 列出PHP可以禁用的函数,如果某些程序需要用到这个函数,可以删除,取消禁用。
expose_php = Off #禁止显示php版本的信息
short_open_tag = ON #支持php短标签
open_basedir = 网站根目录:/tmp/
#设置表示允许访问当前目录(即PHP脚本文件所在之目录)和/tmp/目录;冒号为分隔符。
:wq! #保存退出

open_basedir配置选项中有些教程会配置为open_basedir=.:/tmp/,其中’.’代表当前目录。这种方式在nginx+phpfastcgi下好像行不通。

配置php-fpm
cp /etc/php-fpm.d/www.conf /etc/php-fpm.d/www.confbak #备份原有配置文件
vi /etc/php-fpm.d/www.conf  #编辑
user = nginx #修改用户为nginx
group = nginx #修改组为nginx
:wq #保存退出

10.测试

cd /usr/share/nginx/html
vi index.php #添加以下代码
<?php
phpinfo();
?>
:wq! #保存退出
chown nginx.nginx /usr/share/nginx/html -R #设置权限
service nginx restart #重启nginx
service php-fpm restart #重启php-fpm

在客户端浏览器输入服务器IP地址,可以看到相关的配置信息!说明lnmp配置成功!

至此,CnetOS 安装配置LNMP(Nginx+PHP+MySQL)完成。 ####11.查看版本 查看centos版本

more /etc/issue;
CentOS release 6.8 (Final)

查看nginx版本

nginx -v 
nginx version: nginx/1.6.2

查看mysql版本

mysql -uroot -p
然后输入 password
status;
mysql  Ver 14.14 Distrib 5.5.55, for Linux (x86_64) using readline 5.1

查看php版本

php -v
PHP 5.4.45 (cli) (built: Aug 23 2016 14:41:13)

11.要记录保存的信息

item 信息
VPS 网站网址
用户名密码
VPS上面的实例 IP地址
centos的root密码
CentOS release 6.3 (Final)
mysql mysqlroot密码
