LAMP环境搭建与配置(四)

一、查看PHP加载了哪些模块

# /usr/local/php/bin/php -m

二、安装一个redis模块

#cd /usr/local/src
#wget http://pecl.php.net/get/redis-2.2.5.tgz

1.下载redis

[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget http://pecl.php.net/get/redis-2.2.5.tgz
[root@localhost src]# ls
apr-1.6.5              mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
apr-1.6.5.tar.gz       php-5.6.30
apr-util-1.6.1         php-5.6.30.tar.gz
apr-util-1.6.1.tar.gz  php-7.1.6.tar.bz2
httpd-2.4.46           redis-2.2.5.tgz
httpd-2.4.46.tar.gz

2.解压redis

[root@localhost src]# tar -zxvf redis-2.2.5.tgz

3.编译redis

[root@localhost src]# cd redis-2.2.5
[root@localhost redis-2.2.5]# ls
arrays.markdown  CREDITS          redis_array.c       redis_session.c
common.h         library.c        redis_array.h       redis_session.h
config.m4        library.h        redis_array_impl.c
config.w32       php_redis.h      redis_array_impl.h
COPYING          README.markdown  redis.c
[root@localhost redis-2.2.5]# /usr/local/php/bin/phpize
[root@localhost redis-2.2.5]# ./configure --with-php-config=/usr/local/php/bin/php-config
[root@localhost redis-2.2.5]# make
[root@localhost redis-2.2.5]# make install

4.扩展模块

①查看扩展模块存放目录

==我们可以在php.ini中去自定义该路径 ==

[root@localhost redis-2.2.5]#  /usr/local/php/bin/php -i |grep extension_dir 
extension_dir => /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226 => /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226
sqlite3.extension_dir => no value => no value

②查看是否有redis.so

make install时编译好的就会放在这个目录里

[root@localhost redis-2.2.5]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
opcache.so  redis.so

增加一行配置

[root@localhost redis-2.2.5]# vi /usr/local/php/etc/php.ini  //可以放到文件最后一行
extension = redis.so  

④重新加载配置-t , graceful

# /usr/local/apache2.4/bin/apachectl -t
# /usr/local/apache2.4/bin/apachectl graceful

⑤查看是否加载了redis模块

[root@localhost redis-2.2.5]# /usr/local/php/bin/php -m | grep redis
redis
