[root@hadoop001 ~]# rpm -qa|grep mysql
[root@hadoop001 ~]# yum install mysql-libs
创建认证
mkdir -p /root/.certs/
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p’ > ~/.certs/qq.crt
certutil -A -n “GeoTrust SSL CA” -t “C,” -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n “GeoTrust Global CA” -t “C,” -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs
cd /root/.certs
certutil -A -n “GeoTrust SSL CA - G3” -t “Pu,Pu,Pu” -d ./ -i qq.crt
配置mail.rc
vi /etc/mail.rc
set [email protected]
set smtp=smtp.qq.com
set [email protected]
#授权码
set smtp-auth-password=dqiqzlqpslvxdieb
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/root/.certs
