### 一、搭建服务前准备工作 ###

##### 1、关掉 selinux #####

# sed -i 's/^\<SELINUX\>=enforcing/SELINUX=disabled/' /etc/selinux/config 
     立即生效
     # setenforce 0

##### 2、关闭防火墙 #####

# iptables -F
    # iptables -X
    # systemctl stop firewalld
    # systemctl disable firewalld

##### 3、安装BBR；升级内核到最新版本/5.0.2 （看需求，可以不安装） #####

载入公钥和yum源
    # rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
    # rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
    # yum install -y yum-plugin-fastestmirror
    # yum --enablerepo=elrepo-kernel install kernel-ml kernel-ml-devel -y
    将kernel-ml 选为第一启动
    # grub2-set-default 0
    # reboot
    重启后，通过 uname -a 查看内核是否切换到最新版
    # echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
    # echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
    # sysctl -p    保存配置文件
    开启BBR
    # sysctl net.ipv4.tcp_available_congestion_control
    # sysctl net.ipv4.tcp_congestion_control
    查看是否开启了bbr
    # lsmod | grep bbr
    tcp_bbr                20480  6

### 二、安装 LNMP 服务 ###

##### 1、安装 Nginx/1.16.0 #####

# rpm -Uvh http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.16.0-1.el7.ngx.x86_64.rpm
    # yum install -y nginx
    启动 nginx
    # systemctl enable nginx
    # nginx

##### 2、安装 PHP/7.2.19 和 php-redis/3.1.6 #####

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    # rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
    # yum -y install php72w-fpm
    # echo 'export LC_ALL=C' > /etc/profile
    # source /etc/profile
    替换 apache 组和用户为 nginx
    # sed -i 's/^\<user\> = apache*/user = nginx/' /etc/php-fpm.d/www.conf
    # sed -i 's/^\<group\> = apache*/group = nginx/' /etc/php-fpm.d/www.conf
    # yum -y install php72w-common php72w-cli php72w-opcache php72w-bcmath php72w-dba php72w-devel php72w-embedded php72w-enchant php72w-gd php72w-imap php72w-interbase php72w-intl php72w-ldap php72w-mbstring php72w-mcrypt php72w-mysql php72w-mysqlnd php72w-odbc php72w-pdo php72w-pdo_dblib php72w-pear php72w-pecl-apcu php72w-pecl-imagick php72w-pecl-memcached php72w-pecl-mongodb php72w-pecl-redis php72w-pecl-xdebug php72w-pgsql php72w-phpdbg php72w-process php72w-pspell php72w-recode php72w-snmp php72w-soap php72w-tidy php72w-xml php72w-xmlrpc --skip-broken
    启动php
    # systemctl enable php-fpm
    # systemctl start php-fpm

##### 3、安装 redis/5.0.5 （看需求，可以不安装） #####

# yum install -y http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
    # yum -y --enablerepo=remi install redis
    # systemctl start redis
    # systemctl enable redis.service

##### 4、安装 MySQL/5.7.27 #####

# yum localinstall  http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm -y
    # yum install mysql-community-server -y
    # yum install mysql-community-devel -y
    启动数据库
    # systemctl enable mysqld
    # systemctl start mysqld

### 三、修改配置 ###

##### 1、修改数据库密码，授权用户连接登录 #####

初始化前密码在此路径下
    grep 'temporary password' /var/log/mysqld.log
    修改 mysql root 密码
    ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
    授权用户登录
    GRANT ALL PRIVILEGES ON *.* TO 'user'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

##### 2、修改 Nginx 配置（如下配置） #####

vim /etc/nginx/conf.d/www.conf 
    server {
        listen          80;
        server_name localhost;
        index index.html index.htm index.php;
        root  /var/www/html/;
        #add_header 'Access-Control-Allow-Origin' '*';
        #add_header 'Access-Control-Allow-Headers' 'X-Requested-With,content-type,app_type,sign,did,time';
        #add_header 'Access-Control-Allow-Methods' 'GET,POST,PUT,DELETE,OPTIONS';
        location ~ \.php($|/) {
            fastcgi_pass  127.0.0.1:9000;
            fastcgi_read_timeout 300;
            fastcgi_index index.php;
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            fastcgi_param  PATH_INFO $fastcgi_path_info;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include         fastcgi_params;
        }
        location / {
           # if ($request_method = 'OPTIONS') {
               #return 204;
           # }
           # add_header 'Access-Control-Allow-Origin' '*';                  
        #    add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS';  
            try_files $uri $uri/ /index.php$is_args$query_string;
            if (!-e $request_filename) {
                rewrite ^(.*)$ /index.php?s=$1 last;
                break;
            }
        }
        access_log off;
    }
    重启 Nginx
    nginx -s reload

##### 3、修改 Redis 配置文件 #####

vim /etc/redis.conf
    ......
    bind 0.0.0.0        允许所有地址登录
    loglevel verbose    设置日志类型
    requirepass 123456  设置密码
    ......
    重启redis
    service redis restart

##### 4、编写phpinfo测试是否环境是否正常 #####

vim /var/www/html/index.html
        <?php
            phpinfo();
        ?>

访问本地IP测试，如果出现php的界面，就证明php环境没有问题
