centos php 扩展(centos 安装python)
大家好,如果您还对centos php 扩展不太了解,没有关系,今天就由本站为大家分享centos php 扩展的知识,包括centos 安装python的问题都会给大家分析到,还望可以解决大家的问题,下面我们就开始吧!
CentOS下PHP安装memcache扩展问题解决方法分享
系统版本是5.2,把安装memcached的方法记录下先:
复制代码
代码如下:
cd~/memcached
wget-c
wget-c
#安装libevent
tar-zxvf libevent-1.4.10-stable.tar.gz
cd libevent-1.4.10-stable
./configure
make
make install
#安装memcached
cd..
tar-zxvf memcached-1.2.8.tar.gz
cd memcached-1.2.8
./configure
make
make install
#如果是64位系统,还需要把libevent的文件复制到/wp-content/lib64/下,用来解决error while loading shared libraries的问题
cp-R/wp-content/local/lib/libevent*/wp-content/lib64/
好了,开始安装php的扩展,恶梦开始了,本以为直接用yum来安装php-devel.x86_64和php-pecl-memcache.x86_64这两个扩展就可以了,可装了后 phpinfo()里根本找不到memcache扩展,把已经装的这两个扩展remove重来,还是不行,goooooooooooooogle,找到了一篇文章《PHP Pecl Memcached module installation problems》,有救喽,先remove掉php-pecl-memcache.x86_64,然后执行了
pecl install memcache
顺利安装上了,打开/etc/php.d/看了下,没有memcache.ini,好吧,手动到/etc/php.ini加上了 extension=memcache.so,好了,重启httpd,刷新 phpinfo(),竟然还没有,我郁闷了。。
回头想想,我好像漏了一个地方没有检查,马上打开/wp-content/lib64/php/modules/查看,果然没有memcache.so,会在哪呢? find-name之,原来躲在/wp-content/local/lib/php/extensions/no-debug-non-zts-20060613/下,复制到/wp-content/lib64/php/modules/再试,久违的 memcache扩展出现了。 T T
Memcached参数说明:
-d选项是启动一个守护进程 -m分配给Memcache使用的内存数量,单位是MB -u运行Memcache的用户 -l监听的服务器IP地址 -p设置Memcache监听的端口,最好是1024以上的端口 -c最大运行的并发连接数,默认是1024,按照你服务器的负载量来设定 -P设置保存Memcache的pid文件
启动:
memcached-d-u root-m 128-c 8192
查看状态:
watch“echo stats| nc 127.0.0.1 11211″
状态说明:
uptime:memcached运行的秒数 cmd_get:查询缓存的次数。这两个数据相除一下就能得到平均每秒请求缓存的次数 cmd_set:设置key=value的次数 get_hits:缓存命中的次数。缓存命中率= get_hits/cmd_get* 100% scurr_items:现在在缓存中的键值对个数

centos 7.2 系统 php7.0.12的 curl 扩展怎么开启
curl是一个广泛使用的用来上传和下载的命令行工具,当然严格来讲,它还可以有别的用途。对于测试来讲,它是Web相关测试非常实用的工具,包括debugging,使用起来非常方便。
下面直接进入主题:
1、直接进入到php源码包中找到原先安装PHP的源码包文件①;
2、直接进入/usr/package/php-7.1.10/ext/curl目录②;
cd/usr/package/php-7.1.10/ext/curl
3、通过phpize工具生成configure文件③;
/usr/local/php/bin/phpize
4、将安装的软件进行配置,检查当前的环境是否满足要安装软件的依赖关系④;
./configure--with-php-config=/usr/local/php/bin/php-config
5、编译程序并安装文件;
make&&make install
6、在php的配置文件php.ini最后一行添加extension=curl.so即可。

CentOSyumphpmcrypt扩展安装方法
使用 yum install php-mcrypt安装mcrypt扩展时会提示没有安装包
Setting up Install Process
No package php-mcrypt available.
Error: Nothing to do
mcrypt是加密扩展库,加载了它可以用他里面自带的22种加密解密算法
CentOS6默认安装的是php5.3.2
默认的 redhat repos php中是没有 mcrypt扩展的
根据红帽的官方消息()RHEL不打算添加PHP的mcrypt的支持

Thanks for the report.
We are not planning to ship mcrypt support for PHP.
解决方法:
从php官网下载新的php 5.3源码包后,解压到本地目录
进入解压目录下的 ext目录后会发现有 mcrypt,
进入 mcrypt目录
#cd/ext/mcrypt
#phpize
注意:如果报-bash:phpize not Found那么 yum install php-devel就可以使phpize进行动态编译安装扩展
#./configure-with-php-config=/usr/sbin/php/bin/php-config
#make&& make install
出现:

Libraries have been installed in:
/var/php-5.3.10/ext/mcrypt/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'.
