安装php

[root@cairui php-7.2.]# tar zxf php-7.2..tar.gz
[root@cairui php-7.2.]# ./configure --help
`configure' configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]

  CPP         C preprocessor
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

编译参数

[root@cairui php-7.2.3]# ./configure --prefix=/opt/php7.2.3 --with-apxs2=/opt/apache/bin/apxs --with-openssl --with-zlib --with-curl --enable-ftp --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-libxml-dir --enable-soap --enable-sockets --with-xmlrpc --with-iconv-dir=/opt/libiconv --with-xsl --with-mysqli --with-pdo-mysql --with-mysqli

PHP中三种主要的MySQL连接方式(.4开始驱动底层实现都是mysqlnd):
http://php.net/manual/zh/mysqli.overview.php
mysqli(首选) pdo_mysql(建议) mysql(不建议)
PHP从5.4开始内置了MySQL驱动mysqlnd:
php-src/ext/mysqlnd/
php-src/ext/mysql/
php-src/ext/mysqli/
php-src/ext/pdo_mysql/
关系:mysql,mysqli,pdo_mysql这3套PHP操作MySQL的编程接口底层都依赖PHP内置的MySQL驱动mysqlnd.

PHP5.3这样启用mysqlnd支持:
--with-mysql=mysqlnd
--with-mysqli=mysqlnd
--with-pdo-mysql=mysqlnd
PHP5.4后留空则默认启用mysqlnd:
--with-mysql
--with-mysqli
--with-pdo-mysql
PHP7开始不再支持--with-mysql.
--with-pdo-sqlite 默认启用,推荐采用pdo_sqlite来操作SQLite.
--with-sqlite3 默认启用,此扩展是试验性质的.
Windows二进制包ext目录下内置了下面几个扩展:
php_mysql.dll
php_mysqli.dll
php_pdo_mysql.dll
php_sqlite3.dll
php_pdo_sqlite.dll
Debian/Ubuntu软件包: php5-mysqlnd php5-sqlite

PostgreSQL Driver for PHP:
--with-pgsql=DIR
--with-pdo-pgsql=DIR
DIR is the PostgreSQL base install directory or the path to pg_config.
Debian/Ubuntu软件包: php5-pgsql
apt-cache depends php5-pgsql 看到其依赖libpq5这个PostgreSQL的C客户端库.
开发包libpq-dev里带了/usr/bin/pg_config.
sudo apt-get install libpq-dev
--with-pgsql=/usr/bin/pg_config
--with-pdo-pgsql=/usr/bin/pg_config

Oracle Driver for PHP:
--with-oci8=DIR
--with-pdo-oci=DIR 此扩展是试验性质的.
DIR defaults to $ORACLE_HOME.
或者安装Oracle Instant Client然后这样指定:
--with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client/lib
--with-pdo-oci=shared,instantclient,/usr/lib/oracle,11.2
Oracle Instant Client下载地址(60MB):

连接mysql数据库测试

[root@cairui htdocs]# cat index.php
<?php
$servername = "127.0.0.1";
$username = "root";
$password = "";

// 创建连接
$conn = new mysqli($servername, $username, $password);

// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
?>

php连接mysql报错No such file or directory

php测试文件如下：

<?php
$con = mysql_connect("localhost","root","zengjie2");
if (!$con)
{
    die('Could not connect: ' . mysql_error());
}
else
{
    echo "ok";
}
?>

访问后提示：

Warning: mysql_connect(): No such file or directory in /usr/local/nginx/html/mysql.php on line
Could not connect: No such file or directory

解决方法：

登陆mysql

输入status，输出如下

Connection id:
Current database:
Current user:    root@localhost
SSL:     Not in use
Current pager:   stdout
Using outfile:   ''
Using delimiter:    ;
Server version:  5.1. Source distribution
Protocol version:
Connection:  Localhost via UNIX socket
Server characterset:    latin1
Db     characterset:    latin1
Client characterset:    latin1
Conn.  characterset:    latin1
UNIX socket:     /var/lib/mysql/mysql.sock
Uptime:   min  sec

记下UNIX socket路径  /var/lib/mysql/mysql.sock

查看/tmp/mysql.sock,不存在这个文件，那么建个Link

cd /tmp
ln -s /var/lib/mysql/mysql.sock mysql.sock

重新访问php文件，成功连接。

以上是一种情况，另外一种情况： 存在/tmp/mysql.sock 但是不存在 /var/lib/mysql/mysql.sock

cd /var/lib
mkdir mysql
cd mysql
ln -s /tmp/mysql.sock mysql.sock

PHP中使用localhost连接Mysql不成功的解决方法
发现问题

昨天在帮同事编译安装Linux环境时，遇到一个问题：
WEB服务器是apache，数据库是MySQL。

于是写了一个测试连接数据库的PHP页面：
复制代码 代码如下:
$mysql = mysql_connect('localhost','root','');
打开 http://localhost/test.php 测试

提示：Can't connect to local MySQL server through socket...

检查环境正常

以为是数据库没有启动，于是查看一下进程，MySQL在进程里，重启了一下MySQL.

使用mysql -u root -p 可以进入MySQL操作界面

直接使用/usr/local/php5/bin/php /web/test.php执行可以连上数据库
apache也重启了，一样无效

疑点：为何网页执行失败，命令执行却成功

这下就郁闷了，使用php命令直接执行就成功，通过网页执行就失败。难道是apache导致？网上搜索了大堆资料也没找到解决方案，重新编译安装apache问题依旧。

把localhost改成127.0.0.1成功

把localhost改成127.0.0.1后竟然连接成功了，开始陷入思考困局：localhost失败127.0.0.1却成功？

ping localhost 地址是127.0.0.1没错

打开hosts加入
复制代码 代码如下:

127.0.0.1 qttc

使用qttc当主机连接也正常，唯独就不认localhost。
localhost连接方式不同导致

为了了解PHP连接数据库时，主机填写localhost与其它的区别阅读了大量资料，最后得知：

当主机填写为localhost时mysql会采用 unix domain socket连接
当主机填写为127.0.0.1时mysql会采用tcp方式连接
这是linux套接字网络的特性，win平台不会有这个问题

解决方法

在my.cnf的[mysql]区段里添加
复制代码 代码如下:
protocol=tcp

保存重启MySQL，问题解决！
