Linux系统安装LNMP后的相关配置优化

Linux系统安装LNMP后的相关配置优化

 

1、设置 开机主动 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

末端 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

 

立即 奏效适才 所设置 的

/sbin/sysctl -p

 

3、在不收场Nginx做事的情况下平滑变革 Nginx设置 

改了/usr/local/webserver/nginx/conf/nginx.conf

用这个下令 测试 

/usr/local/webserver/nginx/sbin/nginx -t

 

出现

假如 屏幕表现 以下两行信息，阐发 设置 文件精确 ：

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

代表设置 没有任何题目 ，可以放心起头推行 

 

4、平滑重启NGINX

/usr/local/webserver/nginx/sbin/nginx -s reload

 

5、编写每天 定时切割Nginx日记 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`

添加到定时义务 中去
