NGINX配置

Linux：
yum報錯找不到mirror：
到/etc目錄下配置resolv.conf加入nameserver IP,如：
nameserver 8.8.8.8
nameserver 8.8.4.4
search localdomain

ngin依賴安裝：
yum install gcc-c++
yum -y install pcre*
yum -y install openssl*
yum -y install gcc gcc-c++ autoconf automake make（可忽略）

增加用戶：
useradd leyou
/home/leyou會自動創建該文件夾

解壓：
tar -xvf

nginx配置：
進入nginx文件夾
./configure --prefix=/opt/nginx --sbin-path=/usr/bin/nginx

編譯安裝：
make && make install

啓動：
nginx
停止：nginx -s stop
重啓：nginx -s reload

測試：
訪問ip後自動跳到nginx歡迎頁面

注意：
nginx配置文件存在於兩個目錄下，通過命令nginx -t既可以檢查nginx.config文件的有效性，又能知道有效文件的路徑

安裝telnet
yum install telnet
yum install telnet-server
yum install xinetd
systemctl enable xinetd.service 加入開機自啓
systemctl enable telnet.socket 加入開機自啓
systemctl start telnet.socket 啓動
systemctl start xinetd 啓動

• 設置nginx開機啓動

  創建一個開機啓動的腳本：

  vim /etc/init.d/nginx
  

  添加以下內容：

  #!/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

  . /etc/rc.d/init.d/functions

  # Check that networking is up.
  [ "$NETWORKING" = "no" ] && exit 0

                value=`echo $opt | cut -d "=" -f 2`
                if [ ! -d "$value" ]; then

• 修改文件權限，並加入服務列表

  # 修改權限
  chmod 777 /etc/init.d/nginx 
  # 添加到服務列表
  chkconfig --add /etc/init.d/nginx 
  

• 設置開機啓動

  chkconfig nginx on
