总结Linux小问题

1：php安装扩展错误：Cannot find config.m4. Make sure that you run /usr/local/bin/phpize in the top level sourc

如果在安装php扩展的时候出现如题的错误：只需到php的安装目录下如：cd /usr/local/php/php-7.0.4/ext/openssl 执行命令：  cp ./config0.m4 ./config.m4 即可解决

2：如果出现configure: error: Cannot find ldap.h 问题

yum install openldap openldap-devel -y

如果安装完后出现：configure: error: Cannot find ldap libraries in /usr/lib 问题

cp -frp /usr/lib64/libldap* /usr/lib/

然后再./configure ...即可

3：cacti安装时报错MySQL TimeZone database

解决办法：登录mysql，执行以下内容

mysql> GRANT SELECT ON mysql.time_zone_name TO cacti@localhost IDENTIFIED BY 'cactiwhsir';
mysql> flush privileges;

然后发现又报错

ERROR: Your MySQL TimeZone database is not populated. Please populate this database before proceeding.

解决办法：执行以下内容

/usr/local/mysql/bin/mysql_tzinfo_to_sql /usr/share/zoneinfo/ | mysql -uroot -p mysql
