php 之 日志系统seaslog安装

特点：

　　1、高性能（使用C语言编写的）。

　　2、无需配置。

　　3、功能完善、使用简单。

安装：

　　打开php的扩展官网：https://pecl.php.net/。

　　然后搜索Seaslog，

　　选择最新的版本下载：

wget https://pecl.php.net/get/SeasLog-1.8.4.tgz

解压：

tar zxvf SeasLog-1.8.4.tgz 

然后进入SeasLog目录

cd SeasLog-1.8.4/

然后执行phpize：

关于什么是phpize，参考博客：https://blog.csdn.net/qq_16399991/article/details/70577740。

phpize

如果显示命令未找到：

就先安装php-dev：

sudo apt-get install php5-dev

下一步，执行configure：

./configure 

如果报错，显示命令未找到php-config，就需要添加自己的php路径：

./configure -- with-php-config=/usr/local/php/bin/php-config

下一步：

sudo make && make install

如果提示目录没有权限，就修改指定目录的权限。

安装结果：

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:

进入目录查看：

cd /usr/lib/php5/20121212/

可以看到：seaslog.so。

然后修改php.ini文件。

如果不知道php.ini文件在哪，可以通过phpinfo查看。

Nginx：

Loaded Configuration File /etc/php5/fpm/php.ini

apache：

Loaded Configuration File /etc/php5/apache2

打开php.ini，增加一行：

extension = "seaslog.so"

然后重启nginx服务或apache服务，再查看phpinfo，就可以看到安装成功。

打开Seaslog的github：https://github.com/SeasX/SeasLog。

找到Seaslog.ini，复制内容到php.ini中。
