1. 查看你的系统有没有安装mysql header
   find / -name mysql.h
  如果有。请指定 --with-mysql=/ 跟你的正常路径。如果没有。请看下一步。
2.redhat安装
  rpm -ivh MySQL-devel-4.1.12-1.i386.rpm
3.debian安装
  apt-get install libmysqlclient15-dev
4.最后一步php的配置选项添加--with-mysql=/usr即可

[root@test-6 php-5.5.38]# make && make install

# make ZEND_EXTRA_LIBS='-liconv'
# make install

[root@test-6 php-5.5.38]# vim /etc/profile.d/php.sh     #添加环境变量
export PATH=/usr/local/php/bin:/usr/local/php/sbin:$PATH

[root@VM ~]# ln -sv /usr/local/php/include/ /usr/include/php    # 添加php-fpm头文件

[root@test-6 php-5.5.38]# cp php.ini-production /etc/php.ini   # 拷贝php.ini配置文件（是在解压包里面拷贝过来的）

优化参数：
        expose_php = Off                //隐藏PHP版本信息
        display_errors                  //显示php的错误信息
        cgi.fix_pathinfo=0   #在 php.ini 中设置，它是用来对设置cgi模式下为php是否提供绝对路径信息或PATH_INFO信息；这会让 PHP 解释器只尝试给定的文件路径，如果没有找到这个文件就停止处理------->配合nginx使用
[root@test-6 php-5.5.38]# cp sapi/fpm/php-fpm.conf /etc/php-fpm.conf    # 拷贝php-fpm 配置文件（是在解压包里面拷贝过来的；或者在安装目录里面etc下面）

[root@test-6 php-5.5.38]# vim /etc/php-fpm.conf     # 调整php-fpm.conf 配置文件
[global]
pid = /usr/local/php/var/run/php-fpm.pid    # 指定pid 文件路径
error_log = /usr/local/php/var/log/php-fpm.log    # 指定错误日志log 路径

user = nginx 
group = nginx 

下面参数的意思分别为：要求：pm.min_spare_servers <= pm.start_servers <= pm.max_spare_servers
    pm = dynamic 如何控制子进程，选项有static和dynamic  
    pm.max_children：静态方式下开启的php-fpm进程数量
    pm.max_requests：php-fpm子进程能处理的最大请求数
    pm.start_servers：动态方式下的起始php-fpm进程数量
    pm.min_spare_servers：动态方式下的最小php-fpm进程数
    pm.max_spare_servers：动态方式下的最大php-fpm进程数量

1.通过命令查看服务器上一共开了多少的 php-cgi 进程
ps -fe |grep "php-fpm"|grep "pool"|wc -l

2.查看已经有多少个php-cgi进程用来处理tcp请求
netstat -anp|grep "php-fpm"|grep "tcp"|grep "pool"|wc -l

3.linux+nginx+php环境中，每个php-fpm进程的内存限制 
设置方法：编辑php-fpm.conf配置文件
php_admin_value[memory_limit] = 128M（我服务器上的配置文件在/etc/php5/fpm/pool.d/www.conf 这个文件是被包含在php-fpm.conf里的） 后边的数字可以随便更改：32M,64M,128M,256M,512M，这个设置可根据你的服务器内存大小和你的需求来写，修改后要加载一下php-fpm服务

-1 //表示没有内存限制

1、phpinfo()函数，
PHP文件中执行phpinfo()函数，提供参数时可查看特定配置

2、 php -i       # 查看php參數
与phpinof()相似，是在命令行中执行。加上 | grep configure，可查看编译参数。

3、php -m
查看PHP开启的扩展模块，Linux、Windows中都可以用。

4、php --ini
查看加载的配置文件信息

listen = 127.0.0.1:9000     #php-fpm的监听端口/也可以写sock文件，这里写什么，必须在nginx里面对应上
pm = static
pm.max_children = 50        #表示fpm模块的最大进程数[静态启动方式设置]

pm.max_requests = 500               #fpm最大支持的请求数量为多少；若设置为0，跟当前的系统资源有关

pid = run/php-fpm.pid
#pid设置，默认在安装目录中的var/run/php-fpm.pid，建议开启

error_log = log/php-fpm.log
#错误日志，默认在安装目录中的var/log/php-fpm.log

log_level = notice
#错误级别. 可用级别为: alert（必须立即处理）, error（错误情况）, warning（警告情况）, notice（一般重要信息）, debug（调试信息）. 默认: notice.

emergency_restart_threshold = 60
emergency_restart_interval = 60s
#表示在emergency_restart_interval所设值内出现SIGSEGV或者SIGBUS错误的php-cgi进程数如果超过 emergency_restart_threshold个，php-fpm就会优雅重启。这两个选项一般保持默认值。

process_control_timeout = 0
#设置子进程接受主进程复用信号的超时时间. 可用单位: s(秒), m(分), h(小时), 或者 d(天) 默认单位: s(秒). 默认值: 0.

daemonize = yes
#后台执行fpm,默认值为yes，如果为了调试可以改为no。在FPM中，可以使用不同的设置来运行多个进程池。 这些设置可以针对每个进程池单独设置。

listen = 127.0.0.1:9000
#fpm监听端口，即nginx中php处理的地址，一般默认值即可。可用格式为: 'ip:port', 'port', '/path/to/unix/socket'. 每个进程池都需要设置.

listen.backlog = -1
#backlog数，-1表示无限制，由操作系统决定，此行注释掉就行。backlog含义参考：http://www.3gyou.cc/?p=41

listen.allowed_clients = 127.0.0.1
#允许访问FastCGI进程的IP，设置any为不限制IP，如果要设置其他主机的nginx也能访问这台FPM进程，listen处要设置成本地可被访问的IP。默认值是any。每个地址是用逗号分隔. 如果没有设置或者为空，则允许任何服务器请求连接

listen.owner = www
listen.group = www
listen.mode = 0666
#unix socket设置选项，如果使用tcp方式访问，这里注释即可。

user = www
group = www
#启动进程的帐户和组

pm = dynamic #对于专用服务器，pm可以设置为static。
#如何控制子进程，选项有static和dynamic。如果选择static，则由pm.max_children指定固定的子进程数。如果选择dynamic，则由下开参数决定：
pm.max_children #，子进程最大数
pm.start_servers #，启动时的进程数
pm.min_spare_servers #，保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.max_spare_servers #，保证空闲进程数最大值，如果空闲进程大于此值，此进行清理

pm.max_requests = 1000
#设置每个子进程重生之前服务的请求数. 对于可能存在内存泄漏的第三方模块来说是非常有用的. 如果设置为 '0' 则一直接受请求. 等同于 PHP_FCGI_MAX_REQUESTS 环境变量. 默认值: 0.

pm.status_path = /status
#FPM状态页面的网址. 如果没有设置, 则无法访问状态页面. 默认值: none. munin监控会使用到

ping.path = /ping
#FPM监控页面的ping网址. 如果没有设置, 则无法访问ping页面. 该页面用于外部检测FPM是否存活并且可以响应请求. 请注意必须以斜线开头 (/)。

ping.response = pong
#用于定义ping请求的返回相应. 返回为 HTTP 200 的 text/plain 格式文本. 默认值: pong.

request_terminate_timeout = 0
#设置单个请求的超时中止时间. 该选项可能会对php.ini设置中的'max_execution_time'因为某些特殊原因没有中止运行的脚本有用. 设置为 '0' 表示 'Off'.当经常出现502错误时可以尝试更改此选项。

request_slowlog_timeout = 10s
#当一个请求该设置的超时时间后，就会将对应的PHP调用堆栈信息完整写入到慢日志中. 设置为 '0' 表示 'Off'

slowlog = log/$pool.log.slow
#慢请求的记录日志,配合request_slowlog_timeout使用

rlimit_files = 1024
#设置文件打开描述符的rlimit限制. 默认值: 系统定义值默认可打开句柄是1024，可使用 ulimit -n查看，ulimit -n 2048修改。

rlimit_core = 0
#设置核心rlimit最大限制值. 可用值: 'unlimited' 、0或者正整数. 默认值: 系统定义值.

chroot =
#启动时的Chroot目录. 所定义的目录需要是绝对路径. 如果没有设置, 则chroot不被使用.

chdir =
#设置启动目录，启动时会自动Chdir到该目录. 所定义的目录需要是绝对路径. 默认值: 当前目录，或者/目录（chroot时）

catch_workers_output = yes
#重定向运行过程中的stdout和stderr到主要的错误日志文件中. 如果没有设置, stdout 和 stderr 将会根据FastCGI的规则被重定向到 /dev/null . 默认值: 空.

include=/usr/local/php7/etc/php-fpm.d/*.conf


cd php-fpm.d/
cp www.conf.default www.conf

2.6修改php-fpm配置文件
cd ..
vim php-fpm.conf    #如果该配置文件不存在这些参数，那么就在php-fpm.d/www.conf
user = nginx
group = nginx
listen = 192.168.137.60:9000       #本机ip 
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8 

sbin]# ./php-fpm -t         #检查配置文件是否正确
[29-Jan-2021 22:41:22] NOTICE: configuration file /usr/local/php/etc/php-fpm.conf test is successful


2.7启动php-fpm
service php-fpm start
Starting php-fpm  done

# netstat -nutlp|grep 9000
tcp        0      0 192.168.137.60:9000     0.0.0.0:*               LISTEN      15756/php-fpm: mast                

3.1创建nginx用户    确保php服务器上创建的nginx用户的uid，gid，组id一致
groupadd -r -g 955 nginx
useradd -M -s /sbin/nologin -g 955 -u 955 nginx
id nginx
uid=955(nginx) gid=955(nginx) groups=955(nginx)  

3.2安装nginx依赖环境
yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++
yum -y groupinstall 'Development Tools'


3.3建立nginx日志存放目录 --这里看情况，日志和pid文件放的位置有你觉得
mkdir -p /var/log/nginx
chown -R nginx.nginx /var/log/nginx/
ll /var/log/nginx/ -d
drwxr-xr-x 2 nginx nginx 6 Nov  8 15:38 /var/log/nginx/

3.4下载并安装nginx
cd /usr/src/
wget http://nginx.org/download/nginx-1.12.0.tar.gz
tar -xvf nginx-1.12.0.tar.gz
cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-debug \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_image_filter_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--http-log-path=/var/log/nginx/access.log \
--error-log-path=/var/log/nginx/error.log \
--with-pcre \
--with-stream

3.5配置nginx的环境变量
echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
. /etc/profile.d/nginx.sh 
which nginx

nginx   #启动nginx
# ss -antl|grep :80
LISTEN     0      128          *:80                       *:*      

3.6nginx的控制方式
# nginx -h
-t      检查配置文件语法
-v      输出nginx版本
-c      制定配置文件路径
-s      发送服务控制信号ํ{stop|quit|reopen|reload}

3.7配置nginx
cd /usr/local/nginx/conf/
vim nginx.conf
        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.php index.html index.htm;    #在这里加上index.php
······
        location ~ \.php$ {
            root           html;
            fastcgi_pass   192.168.137.60:9000;    #php的ip地址
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;    
            include        fastcgi_params;       去掉这几行前面的#号
        }

mkdir -p /usr/local/nginx/html/
chown -R nginx.nginx /usr/local/nginx/html/
cd /usr/local/nginx/html/
vim index.php
<?php
        $link = mysqli_connect('192.168.137.50','root','666666');
if ($link)
        echo "sucessful.";
else
        echo "failure.";
phpinfo();
?>

cd /usr/local/nginx/html
vim index.php
<?php
        $link = mysqli_connect('192.168.137.50','root','666666');
if ($link)
        echo "sucessful.";
else
        echo "failure.";
phpinfo();
?>

[root@localhost ~]# nginx -s reload
[root@localhost ~]# service php-fpm restart 

5.1数据库服务器上创建wordpress数据库及授权帐户(192.168.137.50)
mysql -uroot -p
mysql> create database wordpress;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on wordpress.* to root@'%' identified by '666666';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges ;
Query OK, 0 rows affected (0.00 sec)


5.2下载wordpress并解压到nginx的服务器
cd /usr/src/
wget https://wordpress.org/latest.tar.gz
tar zxf latest.tar.gz 
cp -rf wordpress /usr/local/nginx/html/

5.3下载wordpress并解压到PHP的服务器
cd /usr/src/
wget https://wordpress.org/latest.tar.gz
tar zxf latest.tar.gz 
cp -rf wordpress /usr/local/nginx/html/

5.4修改wordpress
cd /usr/local/nginx/html/wordpress/
cp wp-config-sample.php wp-config.php
vim wp-config.php
#更改的内容
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'wordpress' );

/** MySQL database username */
define( 'DB_USER', 'root' );

/** MySQL database password */
define( 'DB_PASSWORD', '666666' );

/** MySQL hostname */
define( 'DB_HOST', '192.168.137.50' );

/** Database Charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8' );

/** The Database Collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );

文件末尾添加：加不加都无所谓
require_once(ABSPATH . 'wp-settings.php');

define("FS_METHOD","direct");

define("FS_CHMOD_DIR", 0777);

define("FS_CHMOD_FILE", 0777);
