Nginx1.19安装优化监控实时同步手册
环境如下：
[root@xxxxx ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
[root@xxxxx ~]# ls
nginx-1.19.6 nginx-module-vts-master nginx-vts-exporter-0.10.7
nginx-1.19.6.tar.gz nginx-module-vts-master.zip nginx-vts-exporter-0.10.7.zip
安装
# 添加用户
useradd nginx && usermod -s /sbin/nologin nginx
# 安装依赖
yum install gcc gcc-c++ pcre-devel openssl-devel zlib zlib-devel pcre -y
# 编译安装 nginx-module-vts-master 是监控用的，后面会细说

监控
由于要监控 Nginx 的 qps，需要用到 https://github.com/hnlq715/nginx-vts-exporter，而 Nginx-vts-exporter 又依赖于 nginx-module-vts，nginx-module-vts 前面编译的时候已经添加了该模块了。下面配置一下：
http {
vhost_traffic_status_zone;
...
server {
...
location /status {
allow 192.168.201.0/24;
deny all;
vhost_traffic_status_display;
vhost_traffic_status_display_format html;
}
}
}
打开浏览器访问 http://192.168.201.179/status/format/json 即可看到相应指标。这不是重点，看下一个Nginx-vts-exporter，这个自己编译老是有问题，找同事要了现成的包
nohup ./nginx-vts-exporter --nginx.scrape_uri=http://127.0.0.1/status/format/json &
同步
使用 lsyncd + rsyncd 做实时同步。将179的/usr/local/nginx/conf/、/usr/local/nginx/html目录实时同步到180机器上。
179操作：
yum install lsyncd -y
配置
[root@yyyyy web-service]# cat /etc/lsyncd.conf
settings {
logfile = "/tmp/lsyncd.log",
statusFile = "/tmp/lsyncd.status",
pidfile = "/var/run/lsyncd.pid",
statusInterval = 1,
nodaemon = false,
inotifyMode = "CloseWrite",
maxProcesses = 1,
maxDelays = 1,
}
sync {
default.rsync,
source = "/usr/local/nginx/conf/",
target = "xx@192.168.201.180::conf",
default.rsync,
source = "/usr/local/nginx/html/",
target = "xx@192.168.201.180::html",
exclude = "/image",
rsync = {
binary = "/usr/bin/rsync",
archive = true,
compress = false,
owner = true,
perms = true,
whole_file = false,
password_file = "/etc/passwd.txt"
}
}
sync {
default.rsync,
source = "/usr/local/nginx/html/",
target = "xx@192.168.201.180::html",
exclude = "/image",
rsync = {
binary = "/usr/bin/rsync",
archive = true,
compress = false,
owner = true,
perms = true,
whole_file = false,
password_file = "/etc/passwd.txt"
}
}
密码文件
[root@yyyyy]# cat /etc/passwd.txt
RFSiGjEgP$$062Lm
[root@yyyyy]# chmod 400 /etc/passwd.txt
180操作:
安装
yum install rsync -y
配置
[root@xxxxx web-service]# cat /etc/rsyncd.conf
log file = /var/log/rsyncd.log
pidfile = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
secrets file = /etc/rsync.pass
max connections = 0
uid = root
gid = root
port = 873
use chroot = no
read only = no
list = no
timeout = 600
auth users = xx
hosts allow = 192.168.201.179
hosts deny = 0.0.0.0/32
[html]
path = /usr/local/nginx/html/
comment = html
[conf]
path = /usr/local/nginx/conf/
comment = conf
验证文件
/etc/rsync.pass
[root@xxxxx]# chmod 400 /rsync.pass
[root@xxxxx]# cat /etc/rsync.pass
xx:RFSiGjEgP$$062Lm
在179新建一个文件，看看是否会实时同步到180
