4.5、清理开机自启动服务
for i in `chkconfig --list|grep 3:on |awk '{print $1}'`;do chkconfig$i off;done
for i in crond network rsyslog sshd;do chkconfig --level 3 $ion;done
chkconfig --list|grep 3:on
4.6、服务器时间同步
echo '*/5 * * * * /usr/sbin/ntpdate time.windows.com > /dev/null2>&1' >>/var/spool/cron/root
4.7、加大文件描述符
echo '* - nofile 65535' >> /etc/security/limits.conf
tail -1 /etc/security/limits.conf
#重新登陆后生效(无需重启)
ulimit -n(重新登陆后查看)
4.8、
内核参数调优

五、部署开始
5.1、更改
nginx
日
志输出格式
5.1.1、定义日志格式
cat /etc/nginx/nginx.conf
log_format main '$remote_addr - $remote_user [$time_local]"$request" '
'$status$body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
5.1.2、加载日志格式到对应域名配置中
cat /etc/nginx/conf.d/vhost/api.mingongge.com.cn.conf
server {
listen 80;
server_name newtest-msp-api.mingongge.com.cn;
access_log /var/log/nginx/api.mingongge.com.cn.log main;
}
5.1.3、reload生效
5.1.4、清空原输出文件，并查看输出的日志格式
