FREEBSD升级及优化全攻略(1)

来源：sysop 作者：出处：巧巧读书 2006-03-18 进入讨论组

　　FREEBSD系统是一种非常 UNIX、非常 Free、非常 BSD -- UNIX 的操作系统,因为它过UNIX化,太过专业化了,教很多新手无从下手学习本文的目的是使新手可以根据此文章的步骤和方法,架设一台专业,高效,安全的FREEBSD出来,并且可以立即投入实际运用,故文章中对运用及命令的使用多于理论化的知识点的描述,如果您不明白命令有何作用,建议您查查相关资料.

本文假设已经架设好或者新安装了一台FREEBSD系统主机. 本文中引用了很多FREEBSD官方站数据及网上数据,还有更多的是自己在实际工作中的经验,当然,里面的参数并不一定完全适合您,所以请您在使用时,尽可能根据您的实际需要调整一些参数,使您的SERVER的性能完全的发挥出来.本文只是一个总的线索,如果我要拆开来一个一个详细解释,我想会花更多的篇幅来写的,因为我忙着04年1月的自考,只写了实际中的运作情况,请各位朋友见谅.

升级源码树

安装cvsup
进入:/usr/ports/net/cvsup
make clean
make deinstall
make install
make clean
即可

升级系统源码树及ports

更新/usr/share/examples/cvsup目录下stand-cvsup和ports-cvsup文件,并执行cvsup –g –L2 standard-supfile和cvsup –g –L2 ports-cvsup两个文件,升级ports树﹔

重新编译内核

优化编译环境

更新/etc/make.conf文件,做适当的编译优化,我的CPU是Intel的:
CPUTYPE=i686
CFLAGS= -O3 -pipe
COPTFLAGS= -O3 -pipe

升级操作系统

进入/usr/src
执行make world
整个过程很久,需要2小时左右.

升级配置文件

执行mergemaster升级配置文件,在此过程中,需要按i以便系统执行升级﹔

重新编译内核

到/sys/i386/conf里面,cp GENERIC onlinecq,再vi onlinecq优化内核,注意加入下面的内容

#disable ctrl+alt+delete
options SC_DISABLE_REBOOT

#quota limit
options QUOTA

#ipfw support
options IPFIREWALL
options DUMMYNET
options HZ=3000
options IPDIVERT
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
options IPSTEALTH
options TCP_DROP_SYNFIN
options IPFIREWALL_DEFAULT_TO_ACCEPT
options ICMP_BANDLIM

options ACCEPT_FILTER_DATA
options ACCEPT_FILTER_HTTP

#ipfilter support
#options IPFILTER
#options IPFILTER_LOG
#options IPFILTER_DEFAULT_BLOCK

再执行:
/usr/sbin/config onlinecq
cd ../../compile/onlinecq
make depend
make
make install

重新启动服务器
到此为止,服务器操作系统及内核升级成功
reboot

优化FREEBSD

检查升级情况, 使用ssh进入系统,使用uname –a 可以查到是否升级成功﹔

打开防火墙

更新rc.conf里面的设置,加上:
#enable_quotas="YES"
#check_quotas="YES"
firewall_enable="YES"
firewall_script="/etc/rc.firewall"
firewall_type="/etc/ipfw.rules" #create it!
firewall_quiet="NO"
firewall_logging_enable="YES"
log_in_vain="NO"
tcp_drop_synfin="NO"
tcp_restrict_rst="YES"
icmp_drop_redirect="YES"

优化内核参数

修改系统内核参数,实现微调:vi /etc/sysctl.conf

kern.ipc.somaxconn=8192
kern.ipc.maxsockbuf=2097152
kern.maxfilesperproc=32768
kern.maxfiles=65536
kern.securelevel=-1
net.inet.tcp.sendspace=65536
net.inet.tcp.recvspace=32768
net.inet.udp.maxdgram=57344
net.inet.icmp.drop_redirect=1
net.inet.icmp.log_redirect=0
net.inet.ip.redirect=0
net.inet6.ip6.redirect=0
net.inet.icmp.icmplim=100
net.inet.tcp.always_keepalive=0
net.inet.tcp.delayed_ack=0
net.inet.tcp.log_in_vain=0
net.inet.udp.log_in_vain=0
net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1
net.local.stream.sendspace=65535
net.local.stream.recvspace=32768
net.inet.ip.fastforwarding=1
vfs.vmiodirenable=1

安装防火墙

防火墙在上面已经编译入了内核,并且在上面的rc.conf里面已经打开了,所以在此只要设置一下即可! 允许所有IP通过,免得把自己给挡在外面了. ipfw add all from any to any 其它规则根据实际情况来做,如果您想系统每次启动都使用上一次的规则,可以把这些内容加到: vi /etc/ipfw.rules 里面,语法规则同ipfw.

安装数据库MYSQL

安装mysql40-server和mysql40-client
进入/usr/ports/databases/mysql40-server
执行:
make clean
make deinstall
make WITH_OPENSSL=yes WITH_LINUXTHREADS=yes BUILD_OPTIMIZED=yes install
或者使用下面可参考的编译参数:BUILD_STATIC=yes
编译成静态执行版本
make clean

更改mysql的root密码:
mysqladmin –uroot –p password 123456

生成/etc/my.cnf,使用如下命令:
vi /etc/my.cnf
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock

[mysqld]
skip-innodb
skip-locking
skip-networking
set-variable = port=3306
set-variable = socket=/tmp/mysql.sock
set-variable = back_log=50
set-variable = connect_timeout=3
set-variable = key_buffer=128M
set-variable = max_connections=1000
set-variable = max_allowed_packet=1M
set-variable = net_buffer_length=8K
set-variable = wait_timeout=3
set-variable = read_buffer_size=1M
set-variable = sort_buffer_size=1M
set-variable = table_cache=256
set-variable = myisam_sort_buffer_size=32M
set-variable = log_slow_queries=/var/log/log_slow_queries.log
#log-bin
server-id = 1

[mysqldump]
quick
set-variable = max_allowed_packet=16M

[mysql]
no-auto-rehash
# Remove the next comment character if you are not familiar with SQL
#safe-updates

[isamchk]
set-variable = key_buffer=20M
set-variable = sort_buffer=20M
set-variable = read_buffer=2M
set-variable = write_buffer=2M

[myisamchk]
set-variable = key_buffer=20M
set-variable = sort_buffer=20M
set-variable = read_buffer=2M
set-variable = write_buffer=2M

[mysqlhotcopy]
interactive-timeout

安装phpmyadmin

注意,此步骤需要在apache和php之后再执行
进入/usr/ports/databases/phpmyadmin
执行:
make clean
make deinstall
make install
make clean

新建立一个system的数据库备用.

安装FTP服务器
安装ftp软件(使用pure-ftpd/)
进入/usr/ports/ftp/pufe-ftpd
执行:
make clean
make deinstall
make WITH_MYSQL=1 install
或者使用下面可参考的编译参数:WITH_LANG=simplified-chinese
使用简体中文语言包
make clean
配置pure-ftpd,主要需要做以下的工作:
cp /usr/local/etc/pure-ftpd.conf.sample /usr/local/etc/pure-ftpd.conf
cp /usr/local/etc/pureftpd-mysql.conf.sample /usr/local/etc/pureftpd-mysql.conf

再修改/usr/local/etc/pure-ftpd.conf的如下部份为:
NoAnonymous yes
MySQLConfigFile /usr/local/etc/pureftpd-mysql.conf

再修改/usr/local/etc/pureftpd-mysql.conf的如下部份为您的设定值:
# Mandatory : user to bind the server as.
MYSQLUser demo
# Mandatory : user password. You must have a password.
MYSQLPassword demo
# Mandatory : database to open.
MYSQLDatabase demo

再进入使用mysql –uroot –p123456 进入mysql的文本方式﹔
使用如下命令建立新表:
use system;
DROP TABLE IF EXISTS users;
CREATE TABLE users (
User varchar(16) NOT NULL default '',
status enum('0','1') NOT NULL default '0',
Password varchar(64) NOT NULL default '',
Uid varchar(11) NOT NULL default '-1',
Gid varchar(11) NOT NULL default '-1',
Dir varchar(128) NOT NULL default '',
ULBandwidth smallint(5) NOT NULL default '0',
DLBandwidth smallint(5) NOT NULL default '0',
comment tinytext NOT NULL,
ipaccess varchar(15) NOT NULL default '*',
QuotaSize smallint(5) NOT NULL default '0',
QuotaFiles int(11) NOT NULL default 0,
PRIMARY KEY (User),
UNIQUE KEY User (User)
) TYPE=MyISAM;

安装pureftpd_php_manager

下载pureftpd_php_manager.zip
解压并放到指定的目录里面,比如:
/usr/local/www/data
chmod –R 755 /usr/local/www/data/pureftpd_php_manager

再加入一个普通用户和一个群组,以供ftp使用:
pw groupadd ftpusers
pw useradd ftpuser –g ftpusers –s /sbin/nologin

记住他们的uid和gid号,备用!

进入并编辑pureftp.config.php文件
更改里面的如下行:
$PUREFTP_CONFIG_FILE = '/usr/local/etc/pureftpd-mysql.conf';^M

$DefaultUser = "ftpuser"; # Default User Logon^M
$DefaultPass = ""; # Default User Password^M
$DefaultUid = "1002"; # Default User ID ( must be a re
al user acct )^M
$DefaultGid = "1001"; # Default Group ID ( must be a r
eal group acct )^M
$DefaultDir = "/home"; # Default User Dir ( use
/./ at the end to chroot )^M
$DefaultUL = "0"; # Default Upload Throttl
e ( 0 disables it )^M
$DefaultDL = "0"; # Default Download Throt
tle ( 0 disables it )^M
$Defaultip = "*"; # Default IP restriction
s ( * = any IP )^M
$DefaultQS = "200"; # Default Quota Size ( 0 disable
s it )^M
$Defaultcmt = ""; # Default Comment for us
er^M
^M
// UA^M
$DefaultQF = "0"; # Default Quota Files ( 0 disabl
