一、获取相关开源程序

1.利用CentOS Linux系统自带的yum命令安装、升级所需的程序库：

LANG=C
yum -y install gcc gcc-c++ autoconf freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers patch libtool automake telnet cmake bison bind-utils jwhois setuptool ntsysv

2.下载适用CentOS程序源码包：

这里用OpenResty(也称为ngx_openresty)代替了标准的Nginx。它是一个全功能的 Web 应用服务器。它打包了标准的Nginx核心，很多的常用的第三方模块，以及它们的大多数依赖项。

二、安装Nginx所需的LuaJIT

下载地址：http://luajit.org/download.html

wget "http://luajit.org/download/LuaJIT-2.0.5.tar.gz"
tar -zxf LuaJIT-2.0.5.tar.gz
cd LuaJIT-2.0.5
make && make install

三、安装Nginx所需的pcre库

下载地址：http://www.pcre.org/、https://mirrors.aliyun.com/exim/pcre/

wget "https://mirrors.aliyun.com/exim/pcre/pcre2-10.37.tar.gz"
tar -zxf pcre2-10.37.tar.gz

四、安装Nginx

1、编译安装Nginx

下载地址：https://openresty.org/cn/download.html

wget "https://openresty.org/download/openresty-1.15.8.3.tar.gz"
tar -zxf openresty-1.15.8.3.tar.gz
cd openresty-1.15.8.3
./configure --user=www --group=www --prefix=/usr/local --with-luajit --with-stream --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-http_realip_module --with-http_v2_module --with-threads --with-debug --with-http_addition_module --with-http_gzip_static_module --with-pcre2=../pcre2-10.37 --http-client-body-temp-path=/var/cache/nginx/client_body --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp
gmake && gmake install

2、创建Nginx日志目录

mkdir -p /var/log/nginx
mkdir -p /var/cache/nginx
chown -R www:www /var/log/nginx
chown -R www:www /var/cache/nginx

3、删除不必要的文件

rm -rf /usr/local/bin/md2pod.pl
rm -rf /usr/local/bin/nginx-xml2pod
rm -rf /usr/local/bin/openresty
rm -rf /usr/local/bin/opm
rm -rf /usr/local/bin/resty
rm -rf /usr/local/bin/restydoc
rm -rf /usr/local/bin/restydoc-index

rm -rf /usr/local/COPYRIGHT
rm -rf /usr/local/resty.index
rm -rf /usr/local/site

4、创建Nginx配置文件

在/usr/local/nginx/conf/目录中创建nginx.conf文件

rm -f /usr/local/nginx/conf/nginx.conf
vim /usr/local/nginx/conf/nginx.conf

输入以下内容：Nginx配置文件

5、启动Nginx

ln -s /usr/local/lib/libpcre.so.1 /usr/lib64/libpcre.so.1
/usr/local/nginx/sbin/nginx

三、配置开机自动启动Nginx

开机启动Nginx

vim /etc/systemd/system/nginx.service

在文件中增加以下内容

[Unit]
Description=Nginx
After=network.target

[Service]
Type=forking
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecStop=/usr/local/nginx/sbin/nginx -s stop
ExecReload=/usr/local/nginx/sbin/nginx -s reload
Restart=on-failure
RestartSec=3

[Install]
WantedBy=multi-user.target

修改完nginx.service文件后，需要重新加载systemd的配置，以便它能够识别新的或修改过的服务文件：systemctl daemon-reload

启动Nginx

systemctl start nginx.service

在开机时启用

systemctl enable nginx.service

四、日志切割脚本

1、shell脚本/var/www/scripts/cut_nginx_log.sh

#!/bin/bash

# The Nginx logs path
src_path="/var/log/nginx/"
dst_path="/var/log/nginx/"

files=`ls ${src_path} | grep ".log"`

mkdir -p ${dst_path}$(date -d "-1 day" +"%Y")/$(date -d "-1 day" +"%m")/

for i in $files
do
    if [ -f ${src_path}${i} ]
    then
        is=`echo $i | sed 's/\.log$//g'`
        mv ${src_path}${i} ${dst_path}$(date -d "-1 day" +"%Y")/$(date -d "-1 day" +"%m")/${is}-$(date -d "-1 day" +"%Y%m%d").log
    fi
done

# 删除两个月前的数据
rm -rf ${dst_path}$(date -d "-3 month" +"%Y")/$(date -d "-3 month" +"%m")

kill -USR1 `cat /usr/local/nginx/nginx.pid`

2、添加到Linux定时任务

# 定时切割Nginx日志
0 0 * * * /var/www/scripts/cut_nginx_log.sh > /dev/null 2>&1

附：Nginx错误日志级别说明

error_log file [debug|info|notice|warn|error|crit]|[{debug_core|debug_alloc|debug_mutex|debug_event|debug_http|debug_mail|debug_mysql}]

日志级别 = 错误日志级别 | 调试日志级别; 或者

日志级别 = 错误日志级别

错误日志的级别: emerg, alert, crit, error, warn, notic, info, debug,

调试日志的级别: debug_core, debug_alloc, debug_mutex, debug_event, debug_http, debug_mail, debug_mysql

error_log 指令的日志级别配置分为 错误日志级别和调试日志级别且错误日志只能设置一个级别且错误日志必须书写在调试日志级别的前面且调试日志可以设置多个级别
