設定系統紀錄

編輯 /etc/syslog-ng/syslog-ng.conf 增加

# Postfix
filter f_postfix { program("postfix"); };
destination d_mail { file("/var/log/maillog"); };
log { source(src); filter(f_postfix); destination(d_mail); };

# SSHd
filter f_sshd { program("sshd"); };
destination d_sshd { file("/var/log/secure"); };
log { source(src); filter(f_sshd); destination(d_sshd); };
``
重啟

/etc/init.d/syslog-ng reload


### RAID

http://en.gentoo-wiki.com/wiki/Onboard_RAID

gentoo boot 參數要加 dodmraid

emerge dmraid fdisk /dev/dm-0 dmraid -ay mount /dev/dm-3 gentoo

grub --device-map=/dev/null device (hd0) /dev/mapper/isw_degaagdejg_Volume0 root (hd0,0) setup (hd0) quit

genkernel all --dmraid ``

改 apache2 的最大承載

vi /etc/apache2/httpd.conf
找到
裡面增加 ServerLimit 2000
將 MaxClients 改成 2000
存檔
重新啟動

設定開機要執行的程式

修改 /etc/local.d/*.start
將指令放在裡面

預設 kernel 設定檔

在 /usr/share/genkernel/x86/kernel-config-2.6
