cluster_library.h config.m4 crc16.h liblzf php_redis.h redis_array.h redis.c redis_commands.c redis_session.h

4. 阅读INSTALL.markdown，了解详细的安装步骤与说明

5. 开始安装

# phpize会根据本地的php环境生成configure文件
phpize
Configuring for:
PHP Api Version: 20170718
Zend Module Api No: 20170718
Zend Extension Api No: 320170718

# 查看configure帮助信息，了解详细的安装参数
./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]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]

Optional Features and Packages:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-libdir=NAME Look for libraries in .../NAME rather than .../lib
--with-php-config=PATH Path to php-config php-config
--enable-redis Enable redis support
--disable-redis-session Disable session support
--disable-redis-json Disable json serializer support
--enable-redis-igbinary Enable igbinary serializer support
--enable-redis-msgpack Enable msgpack serializer support
--enable-redis-lzf Enable lzf compression support
--with-liblzf=DIR Use system liblzf
--enable-shared=PKGS Build shared libraries default=yes
--enable-static=PKGS Build static libraries default=yes
--enable-fast-install=PKGS
Optimize for fast installation default=yes
--with-gnu-ld Assume the C compiler uses GNU ld default=no
--disable-libtool-lock Avoid locking (might break parallel builds)
--with-pic Try to use only PIC/non-PIC objects default=use both
--with-tags=TAGS Include additional configurations automatic


Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP 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.

Report bugs to the package provider.

# 设置配置参数
./configure \
--with-php-config=/usr/local/php7.2/bin/php-config \
--enable-redis

# 编译与安装
make && make install

# 出现下面的信息(部分)，说明安装成功
... ...
... ...
----------------------------------------------------------------------
Libraries have been installed in:
/mydata/download/redis-5.0.2/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Installing shared extensions: /usr/local/php7.2/lib/php/extensions/debug-non-zts-20170718/

6. 配置php.ini，添加extension=redis.so

; Redis extension
extension=redis.so

7. 重启php-fpm

service php-fpm restart
Redirecting to /bin/systemctl restart php-fpm.service

# php-fpm.service文件位置
/usr/lib/systemd/system/php-fpm.service

# php-fpm.service文件内容
[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target

[Service]
Type=simple
PIDFile=/usr/local/php7.2/var/run/php-fpm.pid
ExecStart=/usr/local/php7.2/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php7.2/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

8. 检测redis扩展是否安装成功

# 查看php中已安装模块，显示redis，说明安装成功
php -m|grep redis
redis

9. 关于扩展的使用说明，可以查看：https://github.com/phpredis/phpredis/#classes-and-methods
