第十六周

1、源码编译安装LNMP架构环境；
  安装必要的包组和依赖的包
yum groupinstall “Development Tools” “Development Libraries” 
yum install wget openssl-devel ncurses-devel cmake pcre-devel libxml2-devel bzip2-devel libcurl-devel libmcrypt-devel 
   关闭防火墙和selinux

安装编译Nginx  （gcc openssl-devel pcre-devel zlib-devel）
创建nginx用户和用户组
[root@CentOS7 sources]# groupadd -r nginx
[root@CentOS7 sources]# useradd -r -g nginx nginx
编译
[root@CentOS7 sources]# tar xf nginx-1.6.1.tar.gz
[root@CentOS7 nginx-1.6.1]# ./configure  
 –prefix=/usr   
–sbin-path=/usr/sbin/nginx   
–conf-path=/etc/nginx/nginx.conf   
–error-log-path=/var/log/nginx/error.log   
–http-log-path=/var/log/nginx/access.log   
–pid-path=/var/run/nginx/nginx.pid    
–lock-path=/var/lock/nginx.lock   
–user=nginx   
–group=nginx   
–with-http_ssl_module   
–with-http_flv_module   
–with-http_stub_status_module   –
–with-http_gzip_static_module   
–http-client-body-temp-path=/var/tmp/nginx/client/   
–http-proxy-temp-path=/var/tmp/nginx/proxy/   
–http-fastcgi-temp-path=/var/tmp/nginx/fcgi/   
–http-uwsgi-temp-path=/var/tmp/nginx/uwsgi  
 –http-scgi-temp-path=/var/tmp/nginx/scgi   –with-pcre
[root@CentOS7 nginx-1.6.1]# make && make install
[root@CentOS7 nginx-1.6.1]# mkdir -p /var/tmp/nginx/client
  命令生效
[root@CentOS7 profile.d]# vim /etc/profile.d/nginx.sh
export PATH=/usr/local/nginx/sbin:$PATH
[root@CentOS7 profile.d]#  .  /etc/profile.d/nginx.sh
 启动nginx
[root@CentOS7 profile.d]# nginx –t  检查
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@CentOS7 profile.d]# nginx
编译安装mysql
创建mysql用户与用户组，创建数据库目录
[root@CentOS7 sources]# groupadd -r mysql
[root@CentOS7 sources]# useradd -r -g mysql mysql
[root@CentOS7 /]# mkdir -p /data/mysql
[root@CentOS7 /]# chown mysql:mysql /data/mysql
  
编译安装
[root@CentOS7 sources]# tar fx mariadb-5.5.46-linux-x86_64.tar.gz -C /usr/local
[root@CentOS7 sources]# cd /usr/local
[root@CentOS7 sources]# cd mariadb-5.5.46-linux-x86_64/
[root@CentOS7 local]# ln -sv mariadb-5.5.46-linux-x86_64 mysql”mysql” -> “mariadb-5.5.46-linux-x86_64”
[root@CentOS7 local]# cd mysql/
[root@CentOS7 mysql]# chown root.mysql ./
[root@CentOS7 mysql]# scripts/mysql_install_db –user=mysql –datadir=/data/mysql
  创建服务
[root@CentOS7 mysql]#  cp support-files/mysql.server /etc/init.d/mysqld
[root@CentOS7 mysql]# chkconfig –add mysqld  
[root@CentOS7 etc]# cp my.cnf{,.bak}
   mysql创建配置文件并修改
[root@CentOS7 mysql]# cp support-files/my-large.cnf  /etc/my.cnf

[root@CentOS7 mysql]# vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
innodb_file_per_table= ON
skip_name_resolve= ON
  启动服务
[root@CentOS7 mysql]# service mysqld start
Starting MySQL… SUCCESS! 
[root@CentOS7 mysql]# ss –tnl
State       Recv-Q Send-Q                     Local Address:Port                                    Peer Address:Port              
LISTEN      0      50                                     *:3306                                               *:

编译安装php

[root@CentOS7 sources]# tar xf php-5.6.31.tar.gz 
[root@CentOS7 sources]# cd php-5.6.31/
[root@CentOS7 php-5.6.31]# ./configure 
–prefix=/usr/local/php 
–with-mysql=/usr/local/mysql
 –with-openssl 
–enable-fpm
 –enable-sockets 
–enable-sysvshm 
–with-mysqli=/usr/local/mysql/bin/mysql_config 
–enable-mbstring
–with-freetype-dir
–with-jpeg-dir 
–with-png-dir 
–with-zlib-dir 
–with-libxml-dir=/usr 
–enable-xml 
–with-mhash 
–with-mcrypt 
–with-config-file-path=/etc 
–with-config-file-scan-dir=/etc/php.d 
–with-bz2 
–with-curl
[root@CentOS7 php-5.6.31]# make && make install
    创建服务
[root@CentOS7 php-5.6.31]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@CentOS7 php-5.6.31]# chmod +x /etc/init.d/php-fpm
   为php-fpm提供配置文件
[root@CentOS7 sources]#cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@CentOS7html]# echo “fastcgi_param  SCRIPT_FILENAME    \$document_root\$fastcgi_script_name;” >> /etc/nginx/fastcgi_params 与nginx有关
   为php提供配置文件：
[root@CentOS7 php-5.6.31]# cp /sources/php-5.6.31/php.ini-development /usr/local/php/php.ini
   修改php-fpm配置
[root@CentOS7 php-5.6.31]# vim /usr/local/php/etc/php-fpm.conf
 pm.max_children = 150
pm.start_servers = 8
pm.min_spare_servers = 5
pm.max_spare_servers = 10
pid = /usr/local/php/var/run/php-fpm.pid
开启服务
[root@CentOS7 sources]# /etc/init.d/php-fpm start
  
   编辑nginx配置文件，添加php
[root@CentOS7 mysql]# vim /etc/nginx/nginx.conf
location / {
            root   /usr/local/nginx/html;
            index  index.php index.html index.htm;
        }
location ~ .php$ {
            root           /usr/local/nginx/html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }
[root@CentOS7 www]# nginx -s reload

建立测试文件，进行测试
[root@CentOS7 local]# vim /usr/local/nginx/html/index.php
<?php
    $conn = mysql_connect(‘127.0.0.1′,’root’,”);
    if ($conn)
        echo “OK”;
    else
        echo “Failure”;
?>

<?php
  phpinfo();
?>

2、编写一个脚本完成以下功能：
   (1)、一键搭建LNMP源码编译环境；
   (2)、可通过在脚本后面跟上一些参数来自定义安装目录等其他选项。”

#!/bin/bash

lnmp() {
echo “安装前环境准备…”
sleep 3
yum remove nginx mysql mariadb php -y
rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

systemctl stop firewalld.service
systemctl disable firewalld.service
setenforce 0
sed -i ‘/^SELINUX\>/d’ /etc/selinux/config
echo “SELINUX=disabled” >>/etc/selinux/config

echo “开始安装nginx…”
