ngnix 安裝

1安裝PCRE庫

  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ 下載最新的 PCRE 源碼包,使用下面命令下載編譯和安裝 PCRE 包:html

cd /data/apps/
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.42.tar.gz
tar -zxvf  pcre-8.42.tar.gz
cd pcre-8.42
./configure
make
make install

查看是否安裝pcre    java

 rpm    -qa   pcre  

安裝pcrenode

http://mirror.centos.org/centos/6/os/x86_64/Packages/pcre-7.8-7.el6.x86_64.rpm
https://centos.pkgs.org/6/centos-x86_64/pcre-7.8-7.el6.x86_64.rpm.html
rpm -ivh pcre-7.8-6.el6.x86_64.rpm

卸載pcrelinux

 rpm   -e  --nodeps    pcre   

 

2 有網絡的狀況下 nginx

2-二、安裝編譯開發工具類庫

   用yum安裝、更新開發工具"Development Tools"和"Server Platform Deveopment",而nginx會依賴openssl-devel和pcre-devel類庫,安裝以下:git

[root@node2 nginx]# yum groupinstall "Development Tools" "Server Platform Deveopment"
[root@node2 ~]# yum install openssl-devel pcre-devel

2-三、建立用戶和用戶組

 分別建立名爲"nginx"的用戶和組,用來運行nginx的worker進程,操做以下:github

[root@node2 nginx]# groupadd -r nginx
[root@node2 nginx]# useradd -r -g nginx nginx

2-四、編譯並安裝

      安裝nginx

  Nginx 通常有兩個版本,分別是穩定版和開發版,您能夠根據您的目的來選擇這兩個版本的其中一個json

cd /data/apps
wget http://nginx.org/download/nginx-1.14.1.tar.gz
tar -zxvf nginx-1.14.1.tar.gz 
cd nginx
-1.14.1

    先configure指定編譯選項,如安裝目錄、上面建立的運行用戶、須要的擴展模塊(SSL、FastCGI)等,選項及參數說明:http://nginx.org/en/docs/configure.html,操做以下:vim

    [root@node2 nginx]# ./configure \
--prefix=/usr \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/tmp/nginx/client/ \
--http-proxy-temp-path=/var/tmp/nginx/proxy/ \
--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
--http-scgi-temp-path=/var/tmp/nginx/scgi \
--with-pcre

      Configure成功以下:centos

以後進行安裝

make && make install

  

2-五、爲nginx提供SysV init服務腳本

  先建立/etc/init.d/nginx服務腳本,這基於ngInx自身提供的命令實現的,腳本內容以下:

vim  /etc/init.d/nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions      
 
# Source networking configuration.
. /etc/sysconfig/network
 
# Check that networking is up.
 
[ "$NETWORKING" = "no" ] && exit 0
 
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx 
make_dirs() {
    # make required directories
    user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
    options=`$nginx -V 2>&1 | grep 'configure arguments:'`
    for opt in $options; do
if [ `echo $opt | grep '.*-temp-path'` ]; then
    value=`echo $opt | cut -d "=" -f 2`
    if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value 
    fi 
fi 
    done 
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval 
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval 
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start 
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo 
}
force_reload() {
    restart 
}
configtest() {
    $nginx -t -c $NGINX_CONF_FILE 
}
rh_status() {
    status $prog 
}
rh_status_q() {
    rh_status >/dev/null 2>&1 
}
case "$1" in
start)
    rh_status_q && exit 0
    $1
    ;; 
stop)
    rh_status_q || exit 0
    $1
    ;; 
restart|configtest)
    $1 
    ;; 
reload)
    rh_status_q || exit 7
    $1
    ;; 
force-reload)
    force_reload
    ;; 
status)
    rh_status
    ;; 
condrestart|try-restart)
    rh_status_q || exit 0
    ;; 
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac

併爲此腳本賦予執行權限,而後添加到系統服務管理列表,並讓其開機自動啓動,操做以下:

[root@node2 nginx]# vim /etc/init.d/nginx
[root@node2 nginx]# chmod +x /etc/init.d/nginx
[root@node2 nginx]# chkconfig --add nginx
[root@node2 nginx]# chkconfig nginx on
[root@node2 nginx]# chkconfig --list nginx

2-六、啓動並訪問測試

    啓動nginx,查看網絡狀態,能夠看到nginx正在監聽80端口;用測試主機訪問nginx主機的IP,能夠看到nginx的歡迎頁面,過程以下:

[root@node2 nginx]# service nginx start
[root@node2 nginx]# netstat -ntulp | grep nginx

若是啓動以後發現報錯,錯誤信息爲

[root@XXXXXXXX  nginx-1.14.1]# service nginx start
Starting nginx: /usr/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

查詢 ll /usr/local/lib  看一看這個目錄 若是有就關聯上

若是是32位系統

[root@lee ~]#  ln -s /usr/local/lib/libpcre.so.1 /lib

若是是64位系統

[root@lee ~]#  ln -s /usr/local/lib/libpcre.so.1 /lib64

而後在啓動nginx就OK了

service nginx start 

 

 

配置本地yum源或者第三方yum源
清理元數據緩存
yum clean all
從新創建元數據緩存
yum makecache

yum install -y unzip zip;

安裝監控軟件

nginx-module-vts 

https://github.com/vozlt/nginx-module-vts

下載路徑  https://codeload.github.com/vozlt/nginx-module-vts/zip/master  

 unzip nginx-module-vts-master.zip

上傳之後 解壓之後 目錄爲

/data/apps/nginx-module-vts-master

移動到軟件目錄

mv /data/apps/nginx-module-vts-master  /opt/soft/nginx-module-vts-master

進入ngnix目錄

執行命令

./configure \
--prefix=/usr \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/tmp/nginx/client/ \
--http-proxy-temp-path=/var/tmp/nginx/proxy/ \
--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
--http-scgi-temp-path=/var/tmp/nginx/scgi \
--with-pcre \
--add-module=/opt/soft/nginx-module-vts-master

 Configure成功以下:

以後進行安裝

make && make install

 

而後下載 nginx-vts-exporter

3、nginx-vts-exporter的使用
exporter會收集nginx性能指標的JSON格式數據,並彙總後暴露監控接口給Prometheus。

https://github.com/hnlq715/nginx-vts-exporter/releases/

下載連接爲

wget https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz

啓動命令爲

/data/apps/nginx-vts-exporter-0.10.3.linux-amd64/nginx-vts-exporter -nginx.scrape_timeout 10 -nginx.scrape_uri http://127.0.0.1/status/format/json
