我用的是0.4的版本，系统是 centos 5.2,安装iredapd 1.3.3来做权限控制,安装的时候用的是mysql,安装后来做权限控制,安装的时候用的是mysql,安装完成后无法启动,日志中也没有出错信息,请版本帮看看,谢谢!

我的配置文件如下:
[root@mail etc]# cat iredapd.ini
[general]
# Listen address and port.
listen_addr     = 127.0.0.1
listen_port     = 7777

# Run as a low privileged user.
# If you don't want to create one, you can try 'nobody'.
run_as_user     = iredapd

# Background/daemon mode: yes, no.
# Detach iredapd from terminal. It's recommended to always running as daemon.
run_as_daemon   = yes

# Path to pid file.
pid_file        = /var/run/iredapd.pid

# Log type: file.
# Set 'log_file = /dev/null' if you don't want to keep the log.
log_type        = file
log_file        = /var/log/iredapd.log

# Log level: info, warning, error, debug.
# 'info' is recommended for product use. sample log entry:
#       INFO user@domain.ltd -> list@domain.ltd, DUNNO
log_level       = debug

# Backend: ldap, mysql.
backend = mysql

[ldap]
# For ldap backend only.
# LDAP server setting.
# Uri must starts with ldap:// or ldaps:// (TLS/SSL).
#
# Tip: You can get binddn, bindpw from /etc/postfix/ldap_*.cf.
#
#uri         = ldap://127.0.0.1:389
#binddn      = cn=vmail,dc=iredmail,dc=org
#bindpw      = mRAEWpGRtlCs1O0QuWpXoaJ36EjRql
#basedn      = o=domains,dc=iredmail,dc=org

# Enabled plugins.
#   - Plugin name is file name which placed under 'src/plugins/' directory.
#   - Plugin names MUST be seperated by comma.
#plugins = ldap_maillist_access_policy

[mysql]
# For MySQL backend only.
server      = 127.0.0.1
db          = vmail
user        = root
password    = youxia1q2w
#alias_table = alias
