一、架构nginx

（1）安装nginx

1.配置yum源

这里写图片描述

2.解压，修改配置文件，安装依赖性
[root@server1 ~]# ls
nginx-1.14.0.tar.gz
[root@server1 ~]# tar zxf nginx-1.14.0.tar.gz   //解压
[root@server1 ~]# ls
nginx-1.14.0  nginx-1.14.0.tar.gz
[root@server1 ~]# cd nginx-1.14.0
[root@server1 nginx-1.14.0]# ls
auto     CHANGES.ru  configure  html     man     src
CHANGES  conf        contrib    LICENSE  README
[root@server1 nginx-1.14.0]# cd src/
[root@server1 src]# ls
core  event  http  mail  misc  os  stream
[root@server1 src]# cd core/
[root@server1 core]# vim  nginx.h

这里写图片描述

[root@server nginx-1.10.1]# vim auto/cc/gcc

这里写图片描述

[root@server1 nginx-1.14.0]# yum install gcc -y   //安装依赖性
[root@server1 nginx-1.14.0]# yum install pcre-devel -y
[root@server1 nginx-1.14.0]# yum install openssl-devel -y
3.源码编译三部曲
[root@server1 nginx-1.14.0]# pwd
/root/nginx-1.14.0
[root@server1 nginx-1.14.0]#  ./configure --prefix=/usr/local/lnmp/nginx  --with-http_ssl_module --with-http_stub_status_module --user=nginx --group=nginx --with-threads  --with-file-aio  //选择安装需要的性能

//没有报错后执行编译
这里写图片描述

[root@server1 nginx-1.14.0]# make   
[root@server1 nginx-1.14.0]# make install
[root@server1 nginx-1.14.0]# ln -s /usr/local/nginx/sbin/nginx /sbin/ 
//创建软连接，所有的二进制文件命令在/sbin下执行
//加入全局变量，与之前软连接的作用相同，这里我还添加了mysql

这里写图片描述

[root@server ~]# source  .bash_profile  //刷新配置

nginx //开启服务
nginx -s reload //刷新策略
nginx -s stop //停止服务

//注意，nginx默认使用得失80端口，与apache的相同，两个不能同时打开，否则会冲突

4.测试

//打开nginx，浏览器如此则显示成功。
这里写图片描述

（2）Nginx负载均衡设置

1.配置文件设置
[root@server1 ~]# vim /usr/local/nginx/conf/nginx.conf
//后端的服务器为server3与server4，默认算法为轮叫
//在测试的server3与server4的/var/www/html/下写下发布网页，下面用于测试。
//限制访问的域名为www.westos.org
//在物理机上设置域名解析

这里写图片描述
这里写图片描述
这里写图片描述

[root@server1 ~]# useradd -M -d /usr/local/lnmp/nginx/ -s  /sbin/nologin  ngnix  
//添加nginx用户
[root@server1 ~]# nginx -s reload  //刷新配置 
[root@server1 ~]# vim /etc/security/limits.conf //设置系统默认文件数

这里写图片描述

2.测试

//访问域名
这里写图片描述

二、架构php

（1）安装php

[root@server ~]# ls
cmake-2.8.12.2-4.el6.x86_64.rpm  mysql-boost-5.7.17.tar.gz
mysql-5.7.17                     php-5.6.35.tar.bz2
[root@server ~]# tar jxf  php-5.6.35.tar.bz2 
[root@server ~]# ls
cmake-2.8.12.2-4.el6.x86_64.rpm  mysql-boost-5.7.17.tar.gz  php-5.6.35.tar.bz2
mysql-5.7.17                     php-5.6.35
[root@server ~]# cd php-5.6.35
[root@server php-5.6.35]#./configure --prefix=/usr/local/lnmp/php  --with-config-file-path=/usr/local/lnmp/php/etc  --with-mysql=mysqlnd  --enable-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

//这里需要安装很多的依赖性，可以每次根据错误的提示进行安装，没有的包在之前分享的链接中可以参考。
[root@server php-5.6.35]# yum install  libxml2-devel  openssl-devel   curl-devel
 gd-devel-2.0.35-11.el6.x86_64.rpm   gmp-devel libmcrypt-devel-2.5.8-9.el6.x86_64.rpm net-snmp-devel  libmcrypt-2.5.8-9.el6.x86_64.rpm  //安装依赖性
[root@server ~]# rpm -ivh re2c-0.13.5-1.el6.x86_64.rpm 
//安装好后继续在测试一下，直到没有报错
[root@server1 ~]# make && make install

（2）配置php

[root@server1 php-5.6.20]# find -name init.d.php-fpm
./sapi/fpm/init.d.php-fpm
[root@server1 php-5.6.20]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm  //拷贝脚本到/etc/init.d/
[root@server1 php-5.6.20]# chmod +x /etc/init.d/php-fpm  //添加可执行权限
[root@server1 php-5.6.20]# cd /usr/local/lnmp/php/etc/
[root@server1 etc]# ls
pear.conf  php-fpm.conf.default  php.ini
[root@server1 etc]# vim php.ini   //设置时区

这里写图片描述

[root@server1 etc]# cp php-fpm.conf.default php-fpm.conf
[root@server1 etc]#vim php-fpm.conf

这里写图片描述

[root@server1 etc]# /etc/init.d/php-fpm start  //开启服务
Starting php-fpm  done

（3）nginx添加php

这里写图片描述
//设置默认发布目录
这里写图片描述

[root@server1 conf]# nginx  -s reload

（4）测试php

[root@server ~]# cd /usr/local/lnmp/nginx/html/  //nginx默认发布目录
[root@server html]# ls
50x.html  index.html
[root@server html]# vim index.php

这里写图片描述
//测试成功
这里写图片描述

三、架构mysql

（1）安装mysql

[root@server1 ~]# tar zxf mysql-boost-5.7.17.tar.gz 
[root@server1 ~]# yum install cmake-2.8.12.2-4.el6.x86_64.rpm -y  //这里我们用cmake
[root@server1 ~]# ls
anaconda-ks.cfg                  install.log         mysql-5.7.17
cmake-2.8.12.2-4.el6.x86_64.rpm  install.log.syslog  mysql-boost-5.7.17.tar.gz
[root@server1 ~]# cd mysql-5.7.17/
[root@server1 mysql-5.7.17]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql
-DMYSQL_DATADIR=/usr/local/lnmp/mysql/data 
-DMYSQL_UNIX_ADDR=/usr/local/mysql/lnmp/data/mysql.sock
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_MYISAM_STORAGE_ENGINE=1
-DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci
-DEXTRA_CHARSETS=all

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
//安装目录
-DMYSQL_DATADIR=/usr/local/mysql/data \
//数据库存放目录
-DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock \ #Unix socket 文件路径
-DWITH_MYISAM_STORAGE_ENGINE=1 \
//安装 myisam 存储引擎

-DDEFAULT_COLLATION=utf8_general_ci \
//校验字符
-DEXTRA_CHARSETS=all \
//安装所有扩展字符集
-DMYSQL_TCP_PORT=3306 \
//MySQL 监听端口

依赖性安装
这里写图片描述

//安装gcc，gcc-c++
[root@server1 mysql-5.7.17]# yum install gcc gcc-c++ -y
[root@server1 mysql-5.7.17]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql
-DMYSQL_DATADIR=/usr/local/lnmp/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/mysql/lnmp/data/mysql.sock -DWITH_INNOBASE_STORAGE_ENGINE=1
 -DWITH_MYISAM_STORAGE_ENGINE=1
 -DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci
-DEXTRA_CHARSETS=all
//CMake Error at cmake/boost.cmake:81 (MESSAGE):
  You can download it with// ##-DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>##//

  This CMake script will look for boost in <directory>.  If it is not there,
  it will download and unpack it (in that directory) for you.

  If you are inside a firewall, you may need to use an http proxy:

  export http_proxy=http://example.com:80

进去更改密码----n-------n------y------y------y
Securing the MySQL server deployment.

Enter password for user root: 

The existing password for the user account root has expired. Please set a new password.

New password: 

Re-enter new password: 

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: n
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : 

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!
