#两个主机都要操作，root下操作，
3、Ldap （主从）安装
#######################Ldap主从配置#####################

安装

yum -y install openldap-servers openldap-clients nss-pam-ldapd
#复制的是什么文件？
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap:ldap /var/lib/ldap/DB_CONFIG

有问题可以考虑：chown -R ldap:ldap /etc/openldap/

启动（设置自启动）

systemctl start slapd
systemctl enable slapd

#设置密码

slappasswd -h {md5} -s "FCA6Pw2"

#################################################
ldapadd -Y EXTERNAL -H ldapi:/// -f set_rootpw.ldif

additional info: modify/add: olcRootPW: no equality matching rule 解决办法：
修改modify.ldif中对应选项的"add"为"replace"即可
