 LNMP架构介绍

lnmp里的php会启动一个服务,nginx把用户请求的php交给php-fpm处理,比如登录网站php要和mysql做交互,查用户的账号和密码,处理完之后,php-fpm会告诉nginx,nginx返回给用户一个结果。Nginx对于一些静态请求就自己处理了,不需要交给php处理。

 MySQL安装

1.如果之前安装过mysql先将mysql删除掉

[[email protected] ~]# cd /usr/local/src/
[[email protected] src]# ls
apr-1.6.3              httpd-2.4.28                                  mongodb-linux-x86_64-rhel70-3.2.9.tgz      php-7.1.6
apr-1.6.3.tar.gz       httpd-2.4.28.tar.gz                           mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz  php-7.1.6.tar.gz
apr-util-1.6.1         mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz  php-5.6.30                                 phpredis-develop
apr-util-1.6.1.tar.gz  mongodb-linux-x86_64-rhel70-3.2.9             php-5.6.30.tar.gz                          phpredis-develop.zip
[[email protected] src]# rm -rf /usr/local/mysql
[[email protected] src]# rm -rf /etc/init.d/mysqld 
[[email protected] src]# 

2.wget下载源码包,解压

[[email protected] src]# tar -zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz 

3.移动目录

[[email protected] src]# mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql
[[email protected] src]# ls /usr/local/mysql/
bin  COPYING  data  docs  include  lib  man  mysql-test  README  scripts  share  sql-bench  support-files
[[email protected] src]# 

4.添加mysql用户(因为之前添加过了就不用再useradd了),删除之前的mysql文件

[[email protected] src]# id mysql
uid=1001(mysql) gid=1001(mysql) 组=1001(mysql)
[[email protected] src]# rm -rf /data/mysql/*
[[email protected] src]# 

5.配置mysql修改my.cnf文件和mysql文件

[[email protected] src]# cd /usr/local/mysql/
[[email protected] mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
[[email protected] mysql]# cp support-files/my-default.cnf /etc/my.cnf
[[email protected] mysql]# cp support-files/mysql.server /etc/init.d/mysql[[email protected] mysql]# vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
socket=/tmp/mysql.sock  

[[email protected] mysql]# vim /etc/init.d/mysql basedir=/usr/local/mysql datadir=/data/mysql
[[email protected] mysql]# mv /etc/init.d/mysql /etc/init.d/mysqld

6.启动mysql,检查是否启动成功

[[email protected] mysql]# /etc/init.d/mysqld start
[[email protected] mysql]# ps aux|grep mysql root 33506 0.0 0.0 113268 324 pts/5 S 17:34 0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/data/mysql --pid-file=/data/mysql/bogon.pid root 33642 1.6 41.2 453136 412676 pts/5 D 17:34 0:02 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/data/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/data/mysql/bogon.err --pid-file=/data/mysql/bogon.pid --socket=/tmp/mysql.sock root 33652 0.1 0.0 112680 584 pts/5 R+ 17:36 0:00 grep --color=auto mysql [[email protected] mysql]#

7.将mysql服务添加到服务列表里并开机启动

[[email protected] mysql]# chkconfig --add mysqld
[[email protected] mysql]# chkconfig mysqld on
[[email protected] mysql]# service mysqld stop Shutting down MySQL.. SUCCESS! [[email protected] mysql]# service mysqld start Starting MySQL.... SUCCESS! [[email protected] mysql]#

PHP安装

 

1.和LAMP安装PHP方法有差别,这里需要开启php-fpm服务,之前php是作为Apache的一个模块,需要指定Apache的路径,用apxs工具配置模块怎么加载。这里就不需要了,因为用不到Apache。Php是作为独立的服务。

2.清理之前编译过的文件,make clean 之后就是刚刚解压的状态

[[email protected] src]# cd php-5.6.30/
[[email protected] php-5.6.30]# make clean
[[email protected] php-5.6.30]# useradd -s /sbin/nologin php-fpm (添加php-fpm用户,-s指定不能登录)

3.重新编译php

[[email protected] php-5.6.30]# ./configure --prefix=/usr/local/php-fpm 
--with-config-file-path=/usr/local/php-fpm/etc
--enable-fpm
--with-fpm-user=php-fpm
--with-fpm-group=php-fpm
--with-mysql=/usr/local/mysql
--with-mysqli=/usr/local/mysql/bin/mysql_config
--with-pdo-mysql=/usr/local/mysql
--with-mysql-sock=/tmp/mysql.sock
--with-libxml-dir
--with-gd
--with-jpeg-dir
--with-png-dir
--with-freetype-dir
--with-iconv-dir
--with-zlib-dir
--with-mcrypt
--enable-soap
--enable-gd-native-ttf
--enable-ftp
--enable-mbstring
--enable-exif
--with-pear
--with-curl
--with-openssl

4.提示少curl包,yum安装

checking for cURL support... yes
checking for cURL in default path... not found
configure: error: Please reinstall the libcurl distribution -
    easy.h should be in <curl-dir>/include/curl/
[[email protected] php-5.6.30]# 

 

[[email protected] php-5.6.30]# yum install libcurl-devel

5.make && make install

6.查看php-fpm配置文件语法是否正确

[[email protected] php-5.6.30]# ls /usr/local/php-fpm/
bin  etc  include  lib  php  sbin  var
[[email protected] php-5.6.30]# ls /usr/local/php
bin  etc  include  lib  php
[[email protected] php-5.6.30]# ls /usr/local/php-fpm/sbin/php-fpm -t
/usr/local/php-fpm/sbin/php-fpm
[[email protected] php-5.6.30]# /usr/local/php-fpm/sbin/php-fpm -t
[08-Feb-2018 22:26:48] ERROR: failed to open configuration file '/usr/local/php-fpm/etc/php-fpm.conf': No such file or directory (2)
[08-Feb-2018 22:26:48] ERROR: failed to load configuration file '/usr/local/php-fpm/etc/php-fpm.conf'
[08-Feb-2018 22:26:48] ERROR: FPM initialization failed
[[email protected] php-5.6.30]#

  

7.拷贝配置文件

 cp php.ini-production /usr/local/php-fpm/etc/php.ini  (复制目录并改名字)
[[email protected] php-5.6.30]# cp php.ini-production /usr/local/php-fpm/etc/php.ini
[[email protected] php-5.6.30]# cd /usr/local/php-fpm/etc/
[[email protected] etc]# ls
pear.conf  php-fpm.conf.default  php.ini
[[email protected] etc]# vim php-fpm.conf

  

[global]              定义全局参数
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]                一个模块的名字
listen = /tmp/php-fcgi.sock          监听的地址
listen.mode = 666                 定义sock文件的权限
user = php-fpm                   用户
group = php-fpm                  用户组
pm = dynamic                    
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024 

8.拷贝启动的脚本

[[email protected] etc]# cd /usr/local/src/php-5.6.30/
[[email protected] php-5.6.30]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[[email protected] php-5.6.30]# chmod 755 /etc/init.d/php-fpm 
[[email protected] php-5.6.30]# chkconfig --add php-fpm
[[email protected] php-5.6.30]# 

 

[[email protected] php-5.6.30]# chkconfig php-fpm on
[[email protected] php-5.6.30]# service php-fpm start

9.提示用户不存在

[[email protected] php-5.6.30]# useradd -s /sbin/nologin php-fpm

  

[[email protected] php-5.6.30]# service php-fpm start
Starting php-fpm  done
[[email protected] php-5.6.30]# ps aux|grep php-fpm

10.php-fcgi的权限为666

[[email protected] php-5.6.30]# ls -l /tmp/php-fcgi.sock 
srw-rw-rw-. 1 root root 0 2月   8 22:48 /tmp/php-fcgi.sock
[[email protected] php-5.6.30]#

            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

9.检查配置文件是否有错

  

[[email protected] conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[[email protected] conf]# 

  

[[email protected] ~]# /etc/init.d/nginx start
[[email protected] logs]# service nginx start
