9、Tengine启动脚本
# vim /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script start and stop the nginx daemon
#
# chkconfig: 2345 55 25
# description: Startup script for nginx

CONFIGFILE=/usr/local/nginx/conf/nginx.conf
PIDFILE=/var/run/nginx.pid
SCRIPTNAME=/etc/init.d/nginx
LOCKFILE=/var/lock/nginx.lock
set -e
[ -x "$DAEMON" ] || exit 0
start() {
echo "Startting Nginx......"
[ -x $DAEMON ] || exit 5
[ -f $CONFIGFILE ] || exit 6
$DAEMON -c $CONFIGFILE || echo -n "Nginx already running!"
[ $? -eq 0 ] && touch $LOCKFILE

sleep 1

exit 3
;;
esac
exit 0
# chmod +x /etc/init.d/nginx
# chkconfig --add nginx
# service nginx start
#---------------------------------------------------------------------------------------------------------------------------------------------
10、Tengine健康检测
# mkdir -p /data/web/data/mycheckweb.act.qq.com
# echo "OK" > /data/web/data/mycheckweb.act.qq.com/index.html
# echo "你的内网IP mycheckweb.act.qq.com" >> /etc/hosts
# touch /var/lock/check_web.lock
#vim /data/web/conf/checkweb_for_nginx.conf
server {
listen 80;
server_name mycheckweb.act.qq.com;
access_log off;
location / {
root /data/web/data/mycheckweb.act.qq.com;
index index.html;
}
location ~ health_status {
check_status;
allow 127.0.0.1;
allow 192.168.1.0/24;
deny all;
}
}
# vim /usr/local/nginx/sbin/check_web.sh
#!/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin
retval=`ping -c 3 mycheckweb.act.qq.com | awk '/received/ {print $4}'`
[[ ${retval} -eq 0 ]] && exit 1
retval=`curl -I -s "http://mycheckweb.act.qq.com" | grep "200 OK"`
if [[ "${retval}x" = "x" ]]; then
[[ -e /usr/local/nginx ]] && /sbin/service nginx restart >/dev/null 2>&1
fi
#chmod +x /usr/local/nginx/sbin/check_web.sh
# crontab -e
*/5 * * * * (flock --timeout=0 /var/lock/check_web.lock /usr/local/nginx/sbin/check_web.sh >/dev/null 2>&1)
#---------------------------------------------------------------------------------------------------------------------------------------------
11、Tengine访问日志切割与清理
# vim /usr/local/nginx/sbin/cut_nginx_log.sh
#!/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin
## the nginx access logs base path
WEBLOG_PATH="/data/logs/web"
retval=`ps aux | grep ngin[x] | wc -l`
if [ ${retval} -eq 0 ]; then
echo "The daemon process for nginx has no found."
exit 1
fi
## avoid errors for USR1 signal, and modify 750 privilege
chown -R nobody:nogroup /data/logs/{nginx,web}
chmod -R 750 /data/logs/{nginx,web}
## cut nginx access logs
for LOGFILE in `find ${WEBLOG_PATH} -type f -name access.log`
do
LOGPATH=`dirname ${LOGFILE}`
mv ${LOGPATH}/access.log ${LOGPATH}/access_$(date -d "yesterday" +"%Y-%m-%d").log
done
kill -USR1 `ps aux | grep nginx | awk '/master/{print $2}'`
## and then modify original privileges
chown -R nobody:nogroup /data/logs/{nginx,web}
chmod -R 640 /data/logs/{nginx,web}
## clear 10 days ago's nginx access logs
LOGFILE=access_$(date -d "10 days ago" +"%Y-%m-%d").log
find ${WEBLOG_PATH} -type f -name ${LOGFILE} -exec rm -f {} \;
# crontab -e
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh >/dev/null 2>&1
#---------------------------------------------------------------------------------------------------------------------------------------------
12、系统优化
##网络参数设置
# vim /etc/sysctl.conf

net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_max_tw_buckets = 80000
net.core.somaxconn = 32768
net.ipv4.tcp_keepalive_probes = 5
net.ipv4.tcp_keepalive_intvl = 20
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216

net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_retries2 = 5
net.ipv4.tcp_mem = 41943040 73400320 94371840
net.ipv4.tcp_max_orphans = 3276800
fs.file-max = 1300000
# sysctl -p
## 文件描述符设置
# echo "ulimit -SHn 65535" >> /etc/profile
# source /etc/profile
#---------------------------------------------------------------------------------------------------------------------------------------------
13、测试
本地HOSTS绑定访问
http://mycheckweb.act.qq.com/health_status
CentOS 6.4制作Tengine的rpm包
Tengine动态开启模块试用
CentOS 6.3用ICC编译PHP5.4.8+Percona5.5.27+Tengine1.4.1
基于淘宝Tengine和Scribe的WEB日志收集方案
基于Tengine部署LNMP环境
