| 一、安装Nginx
useradd www -M -s /sbin/nologin
1、安装依赖：
yum install -y make cmake gcc gcc-c++ autoconf automake libpng-devel libjpeg-devel zlib libxml2-devel ncurses-devel bison libtool-ltdl-devel libiconv libmcrypt mhash mcrypt libmcrypt-devel pcre-devel openssl-devel freetype-devel libcurl-devel
2、下载nginx：
wget http://nginx.org/download/nginx-1.12.1.tar.gz
3、编译安装：
./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-stream
添加第三方模块 --add-module=PATH
make make install clean
Nginx配置rsyslog
vim /usr/local/nginx/conf/nginx.conf
可以配置在http或者server段中，凡是可以配置access_log和error_log的位置都可以配置
# syslog表示使用syslog协议
# server=10.26.2.65 指明远程服务器地址，也可以指定本地
# facility=local7 指明设备管道使用local7
# tag=nginx 标签表示在日志文件中显示时候的标题
# severity=info 表示日志级别
access_log syslog:server=127.0.0.1,facility=local7,tag=nginx,severity=info;
vim /etc/rsyslog.conf
默认有下面的设置，会读取 /etc/rsyslog.d/*.conf 目录下的配置文件
$IncludeConfig /etc/rsyslog.d/*.conf
为nginx创建一个独立的配置文件
vim /etc/rsyslog.d/nginx.conf
$ModLoad imudp
$UDPServerRun 514
local7.* /var/log/nginx/access.log
&~
#如果不加下面的的&~则除了在/var/log/nginx/access.log中写入日志外，也会写入message文件 配置rsyslog的主配置文件，开启远程日志
# vim /etc/sysconfig/rsyslog
SYSLOGD_OPTIONS=”-c 2 -r -m 0″
#-c 2 使用兼容模式，默认是 -c 5
#-r 开启远程日志
#-m 0 标记时间戳。单位是分钟，为0时，表示禁用该功能
配置完成后重启nginx和rsyslog即可
系统优化：

net.ipv4.ip_nonlocal_bind=1
二、安装confd
直接拷贝confd到/usr/local/bin/
修改权限 chmod 755 /usr/local/bin/confd
mkdir -p /etc/confd/{conf.d,templates}
confd -version
vim /etc/confd/templates/account.tmpl
1) 80 443共存
{{range $dir := lsdir "/web/account.italent.cn"}}
upstream {{base $dir}} {
{{$custdir := printf "/web/account.italent.cn/%s/*" $dir}}{{range gets $custdir}}
server {{$data := json .Value}}{{$data.IP}}:80 {{$data.WEIGHT}};
{{end}}
}
server {
listen 80;
listen 443 ssl;
server_name {{base $dir}};
ssl_certificate /usr/local/nginx/certs/{{base $dir}}.crt;
ssl_certificate_key /usr/local/nginx/certs/{{base $dir}}.key;
access_log syslog:server=127.0.0.1,facility=local1,tag=nginx,severity=info;
access_log /var/log/nginx/{{base $dir}}.access.log;
error_log /var/log/nginx/{{base $dir}}.log;
location / {
proxy_pass http://{{base $dir}};
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
{{end}}
2) 80 强制跳转443
{{range $dir := lsdir "/web/account.italent.cn"}}
upstream {{base $dir}} {
{{$custdir := printf "/web/account.italent.cn/%s/*" $dir}}{{range gets $custdir}}
server {{$data := json .Value}}{{$data.IP}}:80 {{$data.WEIGHT}};
{{end}}
}
server {
listen 80;
server_name {{base $dir}};
return 301 https://$server_name$request_uri;
access_log syslog:server=127.0.0.1,facility=local1,tag=nginx,severity=info;
access_log /var/log/nginx/{{base $dir}}.access.log;
error_log /var/log/nginx/{{base $dir}}.log;
}
server {
listen 443 ssl;
server_name {{base $dir}};
ssl_certificate /usr/local/nginx/certs/{{base $dir}}.crt;
ssl_certificate_key /usr/local/nginx/certs/{{base $dir}}.key;
access_log syslog:server=127.0.0.1,facility=local1,tag=nginx,severity=info;
access_log /var/log/nginx/{{base $dir}}.access.log;
error_log /var/log/nginx/{{base $dir}}.log;
location / {
proxy_pass http://{{base $dir}};
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
{{end}}
vim /etc/confd/conf.d/account.toml
[template]
keys = [
"/web/account.italent.cn",
]
owner = "nginx"
mode = "0644"
src = "account.tmpl"
dest = "/usr/local/nginx/conf/conf.d/account.conf"
三、证书拷贝
/usr/local/nginx/certs
