将 ;cgi.fix_pathinfo=1 改为 cgi.fix_pathinfo=0

vim /etc/php-fpm.d/www.conf

将

composer 安装

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

# 使用中国镜像
composer config -g repo.packagist composer https://packagist.phpcomposer.com

# 如要解除镜像执行下面的
# composer config -g --unset repos.packagist

nginx 安装

安装 nginx

yum install nginx

配置

/etc/nginx/nginx.con

server 下面找到 root /usr/share/nginx/html;

改成

/data/wwwroot/www;

index index.php index.html index.htm;

server 尾部加上

        location ~ \.php$ {
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi.conf;
        }

重启

systemctl start php-fpm
systemctl enable php-fpm  # 设置开机重启
systemctl restart nginx  
systemctl enable nginx  # 

测试

在/data/wwwroot/www 目录下创建phpinfo.php

内容如下：

浏览器上输入ip/phpinfo.php,如果出现如下界面，说明PHP和Nginx均安装成功

MySql 安装

wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.16-linux-glibc2.5-x86_64.tar

# 解压
tar -xvf mysql-5.7.16-linux-glibc2.5-x86_64.tar
tar xvfz mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz

# 移动
mv mysql-5.7.16-linux-glibc2.5-x86_64 /usr/local/mysql
cd /usr/local/mysql

# 补全一些目录
mkdir /usr/local/mysql/data
mkdir /var/log/mysql

# 创建用户
useradd mysql -g mysql

# 修改权限
chown -R mysql.mysql /usr/local/mysq

# 安装
/usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data

安装的一些问题解决方案

# 如报错如下
2018-07-14 06:40:32 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-07-14 06:40:32 [ERROR]   Child process: /usr/local/mysql/bin/mysqldterminated prematurely with errno= 32
2018-07-14 06:40:32 [ERROR]   Failed to execute /usr/local/mysql/bin/mysqld --bootstrap --datadir=/usr/local/mysql/data --lc-messages-dir=/usr/local/mysql/share --lc-messages=en_US --basedir=/usr/local/mysql
-- server log begin --

-- server log end --

# 则使用以下命令安装
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

#  如果出现以下错误
/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

# 则安装依赖
yum -y install numactl

配置 /etc/my.cnf

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8
# 取消密码验证
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

# 添加快捷方式
ln -s /usr/local/mysql/bin/mysql /usr/bin

# 将mysql加入服务
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

# 开机自启
chkconfig mysql on

# 开启
systemctl start mysql

# 设置密码
/usr/local/mysql/bin/mysql -u root -p

# 操作mysql数据库
>>use mysql;

# 修改密码
>>update user set authentication_string=password(\'你的密码\') where user=\'root\';
>>flush privileges;
>>exit;

将/etc/my.cnf中的skip-grant-tables删除

# 登录再次设置密码（不知道为啥如果不再次设置密码就操作不了数据库了）
/usr/local/mysql/bin/mysql -u root -p
 >>ALTER USER \'root\'@\'localhost\' IDENTIFIED BY \'修改后的密码\';
>>exit;

# 允许远程连接
/usr/local/mysql/bin/mysql -u root -p
>>use mysql;
>>update user set host=\'%\' where user = \'root\';
>>flush privileges;
>>eixt;
