CentOS6.9yum安装nginx+php7+mysql环境
1.安装nginx
安装依赖

yum -y install gcc gcc-c++ wget automake autoconf libtool libxml2-devel libxslt-devel perl-devel perl-ExtUtils-Embed pcre-devel openssl  openssl-devel

创建一个不能登录的nginx运行用户

groupadd www-data
useradd -s /sbin/nologin -g www-data www-data

创建源码保存目录和运行时的临时文件夹，下载nginx源码，当前稳定版为nginx-1.14.2

mkdir -p /var/cache/nginx
mkdir -p /usr/local/src/nginx
cd /usr/local/src/nginx
wget -c http://nginx.org/download/nginx-1.14.2.tar.gz

解压

tar -zxvf nginx-1.14.2.tar.gz
cd /usr/local/src/nginx/nginx-1.14.2

编译前配置检查

./configure \
--prefix=/usr/local/nginx \
--sbin-path=/usr/local/nginx/sbin/nginx \
--conf-path=/usr/local/nginx/conf/nginx.conf \
--error-log-path=/var/log/nginx/error.log \

  nginx http uwsgi temporary files: "/var/cache/nginx/uwsgi_temp"
  nginx http scgi temporary files: "/var/cache/nginx/scgi_temp"

编译，安装

make
make install

修改配置
nginx详细配置请移步(nginx的configure参数，配置文件，虚拟主机配置，信号控制)

vim /usr/local/nginx/conf/nginx.conf
user  www-data;
pid   /var/run/nginx.pid;

启动nginx

/usr/local/nginx/sbin/nginx

查看进程

ps aux|grep nginx

杀掉进程

pkill -9 nginx

配置服务

vim /usr/lib/systemd/system/nginx.service

输入如下配置

[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
ExecStartPost=/bin/sleep 0.1

[Install]
WantedBy=multi-user.target

注意：如果你是单核服务器，需要加ExecStartPost=/bin/sleep 0.1

否则在执行systemctl start nginx之后，在执行systemctl status nginx时

会出现systemd[1]: Failed to read PID from file /var/run/nginx.pid: Invalid argument

这是因为nginx还未启动完成，systemctl就去寻找pid进程文件了，这是一个已知的bug

地址https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1581864

重新载入 systemd

systemctl daemon-reload

开启开机启动

systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

启动和查看nginx状态

systemctl start nginx
systemctl status nginx

2.安装mysql
注：MySQL从5.5版本开始，通过./configure进行编译配置方式已经被取消，取而代之的是cmake工具。因此，我们首先要在系统中源码编译安装cmake工具。
安装依赖

yum install -y cmake gcc-c++ bison bison-devel ncurses-devel perl-Data-Dumper boost boost-doc boost-devel

创建mysql用户和用户组

groupadd mysql
useradd -g mysql mysql

创建源码存放目录，下载，解压

mkdir -p /usr/local/src/mysql
cd /usr/local/src/mysql
wget -c https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.20.tar.gz
tar -zxvf mysql-boost-5.7.20.tar.gz
cd mysql-5.7.20

创建相应目录并授权

mkdir -p /usr/local/mysql/data
chown -R mysql:mysql /usr/local/mysql/
touch /var/log/mysql.log
chown -R mysql:mysql /var/log/mysql.log
mkdir -p /var/lib/mysql
chown -R mysql:mysql /var/lib/mysql
mkdir -p /var/run/mysqld
chown -R mysql:mysql /var/run/mysqld

配置检查

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data  \
-DSYSCONFDIR=/etc \
-DMYSQL_USER=mysql \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_unicode_ci \
-DWITH_DEBUG=0 \
-DMYSQL_MAINTAINER_MODE=0 \
-DWITH_SYSTEMD=1 \
-DWITH_BOOST=boost \
-DWITH_SSL:STRING=bundled \
-DWITH_ZLIB:STRING=bundled

编译，安装

make
make install

修改mysql配置

vim /etc/my.cnf

如下设置

[mysql]
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock

[mysqld]
init-connect = 'SET NAMES utf8'
character-set-server = utf8
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
user = mysql
explicit_defaults_for_timestamp=true
bind-address = 0.0.0.0
server-id = 1
log_error=/var/log/mysql.log


# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

加入环境变量

vim /etc/profile

尾部加入下面两行

PATH=$PATH:/usr/local/mysql/bin/
export PATH

执行source使环境变量立即生效

source /etc/profile

初始化数据库,安装密钥

mysqld --defaults-file=/etc/my.cnf --initialize-insecure --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
mysql_ssl_rsa_setup

--initialize-insecure不生成随机密码

--initialize生成随机密码

设置开机启动

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system

重新载入 systemd

systemctl daemon-reload

开机启动

systemctl enable mysqld.service
systemctl start mysqld.service
[root@jmsiteos7 mysql-5.7.20]# systemctl status mysqld.service
● mysqld.service - MySQL Server

1月 04 15:36:51 jmsiteos7 systemd[1]: Starting MySQL Server...
1月 04 15:36:52 jmsiteos7 systemd[1]: Started MySQL Server.

设置密码（如果初始化参数是--initialize，这步跳过）

mysql_secure_installation

登录mysql

[root@jmsiteos7 ~]# mysql -uroot -p

3.安装php
安装依赖

yum install libxml2 libxml2-devel curl-devel openjpeg openjpeg-devel openjpeg-libs libjpeg libjpeg-devel libpng freetype libpng-devel freetype-devel openssl openssl-devel

创建源码保存目录，下载，解压

mkdir -p /usr/local/src/php72
cd /usr/local/src/php72
wget -c http://cn2.php.net/get/php-7.2.13.tar.gz
tar -xzvf php-7.2.13.tar.gz
cd php-7.2.13

配置检查

./configure --prefix=/usr/local/php72 \

--with-curl \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir

编译，安装

make -j4
make install

设置环境变量

vim /etc/profile

文件末尾加入如下两行代码

PATH=$PATH:/usr/local/php72/bin/:/usr/local/php72/sbin/
export PATH

使之立即生效

source /etc/profile

测试一下

[root@jmsiteos7 php-7.2.13]# php -v
PHP 7.2.13 (cli) (built: Jan  4 2019 17:35:17) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

设置php.ini和php-fpm.conf，www.conf
进入源码目录

cd /usr/local/src/php72/php-7.2.13

复制示例配置

cp php.ini-development /usr/local/php72/etc/php.ini
#或
cp php.ini-production /usr/local/php72/etc/php.ini

进入php.ini目录

cd /usr/local/php72/etc

打开配置文件

vim /usr/local/php72/etc/php.ini

更改pdo_mysql.default_socket为上面安装mysql时.sock设定的位置

pdo_mysql.default_socket = /var/lib/mysql/mysql.sock

如果不设置，php通过pdo连接mysql时会报SQLSTATE[HY000] [2002] No such file or directory
复制fpm示例配置

cp php-fpm.conf.default php-fpm.conf

进入php-fpm.d目录

cd /usr/local/php72/etc/php-fpm.d

复制www.conf

cp www.conf.default www.conf

设置php-fpm开机启动

cp /usr/local/src/php72/php-7.2.13/sapi/fpm/php-fpm.service /usr/lib/systemd/system/

重新载入 systemd

systemctl daemon-reload

启用开机启动

systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.

启动php-fpm

systemctl start php-fpm

查看状态

[root@jmsiteos7 php-fpm.d]# systemctl status php-fpm

4.验证安装的nginx，php，mysql
编辑nginx配置文件

vim /usr/local/nginx/conf/nginx.conf

#更改运行用户
user  www-data;
#编辑server段，默认文件添加index.php
        location / {
            root   html;
            index  index.php index.html index.htm;
        }
#匹配php的配置块取消注释并更改/scripts为$document_root
        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

保存并退出，重启nginx

systemctl restart nginx

nginx默认的web目录下新建index.php

vim /usr/local/nginx/html/index.php

输入如下php代码

<?php
$dbms='mysql';     //数据库类型
$host='localhost'; //数据库主机名
$dbName='mysql';    //使用的数据库
$user='root';      //数据库连接用户名
$pass='';          //对应的密码
$dsn="$dbms:host=$host;dbname=$dbName";
try {
    $dbh = new PDO($dsn, $user, $pass); //初始化一个PDO对象
    echo "连接成功<br/>";
    foreach ($dbh->query('SELECT db from db') as $row) {
        print_r($row);
    }

    $dbh = null;
} catch (PDOException $e) {
    die ("Error!: " . $e->getMessage() . "<br/>");
}
?>
