1、配置开机自动启动Nginx + PHP
vim /etc/rc.local /home/mysql/mysql start ulimit -SHn 65535 /usr/local/webserver/php/sbin/php-fpm start /usr/local/webserver/nginx/sbin/nginx 2、优化Linux内核参数 vi /etc/sysctl.conf 末尾加上 # Add net.ipv4.tcp_max_syn_backlog = 65536 net.core.netdev_max_backlog = 32768 net.core.somaxconn = 32768 net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2 net.ipv4.tcp_tw_recycle = 1 #net.ipv4.tcp_tw_len = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_mem = 94500000 915000000 927000000 net.ipv4.tcp_max_orphans = 3276800 #net.ipv4.tcp_fin_timeout = 30 #net.ipv4.tcp_keepalive_time = 120 net.ipv4.ip_local_port_range = 1024 65535 立刻生效刚才所配置的 /sbin/sysctl -p 3、在不停止Nginx服务的情况下平滑变更Nginx配置 改了/usr/local/webserver/nginx/conf/nginx.conf 用这个命令测试 /usr/local/webserver/nginx/sbin/nginx -t 出现 如果屏幕显示以下两行信息，说明配置文件正确： the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully 代表配置没有任何问题，可以放心开始执行 4、平滑重启NGINX /usr/local/webserver/nginx/sbin/nginx -s reload 5、编写每天定时切割Nginx日志的脚本 vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh #!/bin/bash # This script run at 00:00 # The Nginx logs path logs_path="/usr/local/webserver/nginx/logs/" mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/ mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid` 添加到定时任务中去 |
