歌声与微笑

nginx安装于/home/web/nginx/
默认日志位于/home/web/nginx/logs/
开设的网站日志存放于/home/logs/目录
对于每天产生的日志，按日期建立目录，把当天的nginx日志移到日期目录内，再重启nginx而产生记录新日志，并过过期日志做自动删除

任务计划如下：
echo "59 23 * * * /home/web/nginx/sbin/cut.sh"  >>/var/spool/cron/root

/home/web/nginx/sbin/cut.sh
内容如下：
#!/bin/bash
# This script will run at 23:59 everyday and will del 10 days ago's log by auto
# The Nginx logs path
logs_path="/home/logs/"
mkdir -p ${logs_path}/$(date -d "today" +"%Y%m%d")
mv ${logs_path}/*.log ${logs_path}/$(date -d "today" +"%Y%m%d")/
mv /home/web/nginx/logs/access.log ${logs_path}//$(date -d "today" +"%Y%m%d")/
mv /home/web/nginx/logs/error.log ${logs_path}//$(date -d "today" +"%Y%m%d")/
rm -rf ${logs_path}/$(date +%Y%m%d -d '10 days ago')
kill -USR1 `cat /home/web/nginx/logs/nginx.pid`

使用yum安装vsftpd，打开所需的日志，并开启被动模式，脚本如下，另存为sh，直接运行即可。

#!/bin/bash

echo "--------------------------------vsftpd 自动安装脚本--------------------------------"

if [ -s /etc/selinux/config ]; then
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

groupadd www
useradd www -g www -d /wwwroot/htdocs -s /sbin/nologin

chown www.www /wwwroot/htdocs
chkconfig vsftpd on
service vsftpd start
echo "--------------------------------vsftpd 安装说明------------------------------------"
echo "|                                                                                  |"
echo "|               用户为 www 密码为刚才所设 FTP根目录为/wwwroot/htdocs               |"
echo "| 新增用户样例为(新增用户ktm):useradd ktm -g www -d /wwwroot/ktm -s /sbin/nologin  |"
echo "|                              service vsftpd restart                              |"
echo "|                                                                                  |"
echo "--------------------------------vsftpd 安装结束!-----------------------------------"
sleep 2

防火墙就不直接更改了，注意另外打开端口20000-20050即可

准备相应的mysql程序，软件安装在/home/web目录，因不用再花大量时间编译，安装很快，较省时。

安装脚本如下：

cur_dir=$(pwd)

# 配置myisam或innodb方式
read -p "do you want to install the InnoDB Storage Engine? (y/n)" mysqlengineer
if [ "$mysqlengineer" = 'y' ]; then
  echo "mysqlengineer is innoDB"
elif
[ "$mysqlengineer" = 'n' ]; then
  echo "mysqlengineer is MYSIAM"
else
   mysqlengineer="y" && echo "mysqlengineer is innoDB"
fi

#确认后暂停

get_char()
{
SAVEDSTTY=`stty -g`
stty -echo
stty cbreak
dd if=/dev/tty bs=1 count=1 2> /dev/null
stty -raw
stty echo
stty $SAVEDSTTY
}
echo ""
echo "Press any key to start..."
char=`get_char`

#开始安装

nginx自从1.1.8版本发布后将limit_conn更换为limit_conn_zone

1.添加limit_zone   这个变量只能在http使用
nginx.conf中:
http {   } 段内添加：
    limit_conn_zone $binary_remote_addr zone=perip:10m;

2.添加limit_conn   这个变量可以在http, server, location使用
针对某个站点，可以直接加到站内配置文件中，如：

        location / {
                index  index.html index.htm index.php;
        limit_conn perip 1;
        limit_rate 100k;
        }

也可以单独加段 location，并配置上要限制的目录

        location /data/ {
        limit_conn perip 1;
        limit_rate 100k;
        }

说明：
limit_conn perip 10;    每个IP使用10个连接
limit_rate 100k;        限制1个连接速度为100k
