基于lnmp架构搭建论坛 / 憋错料

LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。

实验环境：

系统环境: RHEL6 x86-64 selinux and iptables disabled

一、Mysql 安装

1.安装软件包依赖性:

[[email protected] ~]# yum install -y gcc gcc-c++ ncurses-devel bison openssl-devel zlib-devel

[[email protected] ~]# yum install -y cmake-2.8.12.2-4.el6.x86_64.rpm 用cmake[有进度条]

2.编译安装数据库
[[email protected] ~]# tar zxf mysql-boost-5.7.11.tar.gz
[[email protected] ~]# cd mysql-5.7.11/

[[email protected] mysql-5.7.11]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql \ #安装目录

> -DMYSQL_DATADIR=/usr/local/lnmp/mysql/data \ #数据库存放目录

> -DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock \ #Unix socket 文件路径

> -DWITH_INNOBASE_STORAGE_ENGINE=1 \ #安装 innodb 存储引擎

> -DWITH_MYISAM_STORAGE_ENGINE=1 \ #安装 myisam 存储引擎

> -DDEFAULT_CHARSET=utf8 \ #使用 utf8 字符

> -DDEFAULT_COLLATION=utf8_general_ci \ #校验字符

> -DEXTRA_CHARSETS=all \ #安装所有扩展字符集

> -DWITH_BOOST=/root/mysql-5.7.11/boost/boost_1_59_0/

[[email protected] mysql-5.7.11]# make && make install

注意：

重新编译时,需要清除旧的对象文件和缓存信息
make clean
rm -f CmakeCache.txt

3.完成mysql初始化
[创建所需的用户及组]

[[email protected] mysql]# groupadd -g 27 mysql

[[email protected] mysql]# useradd -u 27 -g 27 -M -d /usr/local/lnmp/mysql/ mysql

[[email protected] local]# usermod -s /sbin/nologin mysql
[[email protected] mysql]# chown mysql.mysql . -R

4.解析mysql/bin的执行脚本

[[email protected] ~]# vim .bash_profile

[[email protected] ~]# source .bash_profile

[[email protected] mysql]# chown root . -R

5.修改配置文件中的数据库存放目录socket 文件路径与编译时一致

[[email protected] support-files]# vim /etc/my.cnf

6.拷贝执行脚本到本地执行目录下

[[email protected] support-files]# cp mysql.server /etc/init.d/mysqld

7.完成初始化指定用户并创建数据库

[[email protected] mysql]# mysqld --initialize --user=mysql

[[email protected] mysql]# chown mysql data -R 更改数据目录所有人为mysql

开启数据库并修改密码

[[email protected] mysql]# /etc/init.d/mysqld start

[[email protected] mysql]# mysql_secure_installation #按提示完成 mysql 安全设置,生产环境推荐使用

二、Php 安装

1.解决安装所需依赖性

下载包

php-5.6.20.tar.bz2

安装依赖性

[[email protected] ~]# yum install libjpeg-turbo-devel-1.2.1-1.el6.x86_64
[[email protected] php-5.6.20]# yum install -y libxml2-devel
[[email protected] php-5.6.20]# yum install -y openssl-devel
[[email protected] php-5.6.20]# yum install -y curl-devel
[[email protected] ~]# yum install -y gd-devel-2.0.35-11.el6.x86_64.rpm
[[email protected] ~]# yum install -y gmp-devel
[[email protected] ~]# yum install libmcrypt-devel-2.5.8-9.el6.x86_64.rpm libmcrypt-2.5.8-9.el6.x86_64.rpm -y
[[email protected] ~]# yum install -y net-snmp-devel
[[email protected] ~]# yum install re2c-0.13.5-1.el6.x86_64.rpm -y

2.编译安装

[[email protected] ~]# tar jxf php-5.6.20.tar.bz2 解包

[[email protected] php-5.6.20]# ./configure --help 寻找帮助
--with-openssl 指定驱动加密

--with-gd 图

--with-zlib php网页压缩（防盗链）

--with-pear 功能模块的组件（安装）

执行

[[email protected]
php-5.6.20]# ./configure --prefix=/usr/local/lnmp/php
--with-config-file-path=/usr/local/lnmp/php/etc --enable-mysqlnd
--with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
--with-openssl --with-snmp --with-gd --with-zlib --with-curl
--with-libxml-dir --with-png-dir --with-jpeg-dir --with-freetype-dir
--with-pear --with-gettext --with-gmp --enable-inline-optimization
--enable-soap --enable-ftp --enable-sockets --enable-mbstring
--enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --with-mcrypt
--with-mhash

[[email protected] php-5.6.20]# make && make install

3.配置php解析文件/配置php-fpm配置文件

[[email protected] etc]# cp php-fpm.conf.default php-fpm.conf
[[email protected] etc]# ls
pear.conf php-fpm.conf php-fpm.conf.default
[[email protected] etc]# pwd
/usr/local/lnmp/php/etc

[[email protected] php-5.6.20]# cp php.ini-production /usr/local/lnmp/php/etc/php.ini
[[email protected] fpm]# pwd
/root/php-5.6.20/sapi/fpm
[[email protected] fpm]# cp init.d.php-fpm /etc/init.d/php-fpm       启动脚本
[[email protected] fpm]# chmod +x /etc/init.d/php-fpm         加执行权限

4.修改php配置文件 [pid][timezone]

[[email protected] etc]# vim php-fpm.conf

[[email protected] etc]# vim php.ini

添加php配置文件中指定的用户并启动php

[[email protected] etc]# useradd -u 800 -M -d /usr/local/lnmp/nginx nginx
[[email protected] etc]# /etc/init.d/php-fpm start

三、Nginx 安装

1.安装依赖性并编译

[[email protected] ~]# tar zxf nginx-1.10.1.tar.gz
[[email protected] ~]# cd nginx-1.10.1
[[email protected] core]# pwd
/root/nginx-1.10.1/src/core
[[email protected] core]# vim nginx.h

#define NGINX_VER "nginx" (修改此行, 去掉后面的 “ NGINX_VERSION”,为了安全,这样编译后外界无法获取程序的版本号)

[[email protected] cc]# pwd
/root/nginx-1.10.1/auto/cc
[[email protected] cc]# vim gcc

#CFLAGS=”$CFLAGS -g” (注释掉这行,去掉 debug 模式编译,编译以后程序只有几百 k)

安装依赖

[[email protected] nginx-1.10.1]# yum install -y pcre-devel

编译

./configure
--prefix=/usr/local/lnmp/nginx --with-http_ssl_module
--with-http_stub_status_module --with-file-aio --with-threads
--user=nginx --group=nginx

安装

[[email protected] nginx-1.10.1]# make && make install

做软链接

[[email protected] sbin]# ln -s /usr/local/lnmp/nginx/sbin/nginx /usr/local/sbin/

[[email protected] sbin]# nginx -t 检测语法

[[email protected] ~]# nginx 开启

四、解决nginx和php的依赖关系

编辑nginx配置文件修改tcp zip php

[[email protected] conf]# pwd
/usr/local/lnmp/nginx/conf
[[email protected] conf]# vim nginx.conf

[[email protected] conf]# nginx -t 检测语法
nginx: the configuration file /usr/local/lnmp/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/lnmp/nginx/conf/nginx.conf test is successful
[[email protected] conf]# nginx -s reload 重新加载

创建nginx访问php主页的页面

[[email protected] html]# pwd
/usr/local/lnmp/nginx/html
[[email protected] html]# vim index.php
[[email protected] html]# cat index.php
<?php
phpinfo()
?>

设置index.php为访问ip时默认访问的网页

[[email protected] conf]# vim nginx.conf
