由于前文“http://www.aiuxian.com/article/p-3220064.html”中升级了php到php7，导致之前可以正常使用的phpmyadmin、memcache等无法继续使用，需要重新编译安装，memcache目前未找到有效的解决方法，只好重新安装memcached来替代之前的memcache。此处介绍memcached的安装编译。

1、试图按以前的经验，直接升级memcache：

[root@iZ23d ~]# pecl upgrade memcache bash: pecl: command not found…

根据这边的提示，需要安装相应的 yum install php-devel php-pear httpd-devel

[root@iZ23d ~]#  yum install php70w-devel php70w-pear php70w-httpd-devel     Loaded plugins: langpacks Repository base is listed more than once in the configuration Repository updates is listed more than once in the configuration 。。。。    【其中省略】 Warning: RPMDB altered outside of yum.   Installing : php70w-process-7.0.0-1.w7.x86_64                                           1/4   Installing : php70w-xml-7.0.0-1.w7.x86_64                                               2/4   Installing : 1:php70w-pear-1.10.1-1.w7.noarch                                           3/4   Installing : php70w-devel-7.0.0-1.w7.x86_64                                             4/4   Verifying  : php70w-devel-7.0.0-1.w7.x86_64                                             1/4   Verifying  : php70w-xml-7.0.0-1.w7.x86_64                                               2/4   Verifying  : 1:php70w-pear-1.10.1-1.w7.noarch                                           3/4   Verifying  : php70w-process-7.0.0-1.w7.x86_64                                           4/4   Installed:   php70w-devel.x86_64 0:7.0.0-1.w7              php70w-pear.noarch 1:1.10.1-1.w7   Dependency Installed:   php70w-process.x86_64 0:7.0.0-1.w7              php70w-xml.x86_64 0:7.0.0-1.w7   Complete!

继续按偷懒的方法升级：

[root@iZ23d ~]#   pecl upgrade memcache  downloading memcache-2.2.7.tgz … Starting to download memcache-2.2.7.tgz (36,459 bytes) …..done: 36,459 bytes 11 source files, building running: phpize Configuring for: PHP Api Version:         20151012 Zend Module Api No:      20151012 Zend Extension Api No:   320151012 。。。  【其中省略】

config.status: executing libtool commands running: make /bin/sh /var/tmp/pear-build-rootEb5cjP/memcache-2.2.7/libtool –mode=compile cc -I/usr/include/php -I. -I/var/tmp/memcache -DPHP_ATOM_INC -I/var/tmp/pear-build-rootEb5cjP/memcache-2.2.7/include -I/var/tmp/pear-build-rootEb5cjP/memcache-2.2.7/main -I/var/tmp/memcache -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib  -DHAVE_CONFIG_H  -g -O2   -c /var/tmp/memcache/memcache.c -o memcache.lo libtool: compile:  cc -I/usr/include/php -I. -I/var/tmp/memcache -DPHP_ATOM_INC -I/var/tmp/pear-build-rootEb5cjP/memcache-2.2.7/include -I/var/tmp/pear-build-rootEb5cjP/memcache-2.2.7/main -I/var/tmp/memcache -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /var/tmp/memcache/memcache.c  -fPIC -DPIC -o .libs/memcache.o /var/tmp/memcache/memcache.c:40:40:  fatal error:  ext/standard/php_smart_str.h: No such file or directory  #include “ext/standard/php_smart_str.h”                                         ^ compilation terminated. make: *** [memcache.lo]  Error 1      ERROR: `make’ failed   

说明升级失败，缺乏 php_smart_str.h 文件，查看是否有相应文件的源文件：

[root@iZ23d ~]# find / -name php_smart_str.h /root/php-5.4.16/ext/standard/php_smart_str.h 以上说明 php5中有相应的文件，但是已经下载并解压的 php7源安装包中却没有相应文件，而 
这边前人的经验也表面，可能是Php7本身的某些扩展未做到位。

而根据这边的说法，之前版本的php中的 php_smart_str.h 在 php7 中已经改名为 php_smart_string.h ； 

查看相应的文件：

[root@iZ23d ~]#  find / -name php_smart_string.h     /usr/include/php-zts/php/ext/standard/php_smart_string.h /usr/include/php/ext/standard/php_smart_string.h /root/php-7.0.1RC1/ext/standard/php_smart_string.h 的确有相应的文件，但是，尝试把相应的文件拷贝一份并命名为相应的 php_smart_str.h 后，重新升级编译安装，并不能解决问题。

在github和stackoverflow均看到此问题暂时没有解决方案，只能等Php7完善。不得已，只能放弃。

在寻找memcache解决方案的过程中，发现memcached碰到的问题几乎和memcache一样，但是，却从 stackoverflow 找到一个可行的 memcached 安装方法，并证实有效。下面是具体的过程。

第一步，直接git clone：

[root@iZ23d ~]#  git clone 
链接地址    Cloning into ‘php-memcached’… remote: Counting objects: 2965, done. remote: Total 2965 (delta 0), reused 0 (delta 0), pack-reused 2965 Receiving objects: 100% (2965/2965), 931.47 KiB | 8.00 KiB/s, done. Resolving deltas: 100% (1774/1774), done.

第二步：

[root@iZ23d ~]#  cd php-memcached    [root@iZ23d php-memcached]#  git checkout php7     Branch php7 set up to track remote branch php7 from origin. Switched to a new branch ‘php7’

第三步：

[root@iZ23d php-memcached]#  phpize   Configuring for: PHP Api Version:         20151012 Zend Module Api No:      20151012 Zend Extension Api No:   320151012

第四步：configure 

[root@iZ23d php-memcached]# ./configure 

checking for grep that handles long lines and -e… /usr/bin/grep checking for egrep… /usr/bin/grep -E 。。。 【省略部分】 checking for memcached session support… enabled checking for memcached igbinary support… disabled checking for memcached msgpack support… disabled checking for libmemcached location… configure:  error:  memcached support requires libmemcached. Use –with-libmemcached-dir=<DIR> to specify the prefix where libmemcached headers and library are located

第五步：根据错误提示，重新  configure  ：

先找到相应文件：

[root@iZ23d php-memcached]# find / -name libmemcached   /usr/local/libmemcached /usr/local/libmemcached/include/libmemcached /root/libmemcached-1.0.18/libmemcached   根据文件位置，增加参数 configure    ： 

[root@iZ23d php-memcached]#  ./configure –with-libmemcached-dir=/usr/local/libmemcached checking for grep that handles long lines and -e… /usr/bin/grep checking for egrep… /usr/bin/grep -E checking for a sed that does not truncate output… /usr/bin/sed checking for cc… cc checking whether the C compiler works… yes checking for C compiler default output file name… a.out checking for suffix of executables… checking whether we are cross compiling… no 。。。 checking for sasl/sasl.h… yes checking whether libmemcached supports sasl… no configure:  error: no, libmemcached sasl support is not enabled.  Run configure with –disable-memcached-sasl to disable this check

再根据新提示，继续：

[root@iZ23d php-memcached]#  ./configure –with-libmemcached-dir=/usr/local/libmemcached  –disable-memcached-sasl   checking for grep that handles long lines and -e… /usr/bin/grep 。。。 configure: creating ./config.status config.status: creating config.h config.status: executing libtool commands

终于未出现错误提示！

第六步，make：

[root@iZ23d php-memcached]#  make     /bin/sh /root/php-memcached/libtool –mode=compile cc -I/usr/include/php    -I. -I/root/php-memcached -DPHP_ATOM_INC -I/root/php-memcached/include -I/root/php-memcached/main -I/root/php-memcached -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib -I/usr/local/libmemcached/include  -DHAVE_CONFIG_H  -g -O2   -c /root/php-memcached/php_memcached.c -o php_memcached.lo libtool: compile:  cc -I/usr/include/php -I. -I/root/php-memcached -DPHP_ATOM_INC -I/root/php-memcached/include -I/root/php-memcached/main -I/root/php-memcached -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib -I/usr/local/libmemcached/include -DHAVE_CONFIG_H -g -O2 -c /root/php-memcached/php_memcached.c  -fPIC -DPIC -o .libs/php_memcached.o 。。。。。 【省略部分】 libtool: install: cp ./.libs/memcached.so /root/php-memcached/modules/memcached.so libtool: install: cp ./.libs/memcached.lai /root/php-memcached/modules/memcached.la libtool: finish: PATH=”/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.8.0_45:/root/bin:/sbin” ldconfig -n /root/php-memcached/modules ———————————————————————- Libraries have been installed in:    /root/php-memcached/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’.

根据提示，继续 make test ：

[root@iZ23d php-memcached]#  make test       Build complete. Don’t forget to run ‘make test’. 。。。【省略部分】 Thank you for helping to make PHP better.

第七部， make install ：

[root@iZ23d php-memcached]#  make install    Installing shared extensions:     /usr/lib64/php/modules/   第八步， 重启 Apache，在/etc/php.ini 的最后添加 extension=”memcached.so”，保存退出，重启Apache ： [root@iZ23d php-memcached]# cd ..  [root@iZ23d  ~]#  systemctl restart httpd.service    第九步，验证检查 memcached 安装结果： 查看 php 版本，看看会否报错，若报错，说明 memcached 安装错误，否则多半表示安装成功：   [root@iZ23d ~]#  php -v  PHP 7.0.0 (cli)(built: Dec  2 2015 20:42:32) ( NTS ) Copyright (c) 1997-2015 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies 以上结果说明，memcached安装成功。 查看phpinfo，已经显示memcached的扩展内容，内容展示如下：  

memcached

再次证明 memcached 安装成功！   第十步，启动 memcached ： [root@iZ23d ~]#  systemctl start memcached.service    查看状态： [root@iZ23d ~]#  systemctl status memcached.service   ● memcached.service – Memcached    Loaded: loaded (/usr/lib/systemd/system/memcached.service; disabled; vendor preset: disabled)    Active: active (running) since Mon 2015-12-21 19:55:07 CST; 14s ago  Main PID: 1426 (memcached)    CGroup: /system.slice/memcached.service            └─1426 /usr/bin/memcached -u memcached -p 11211 -m 64 -c 1024   Dec 21 19:55:07 iZ23d2e6hoqZ systemd[1]: Started Memcached.
