Linux服务篇之Nginx第二篇

简介

• 这一篇主讲编译安装Nginx
• 和等等一些配置
• 那我们开始

准备工作

• 准备好yum源
• CentOS系统,我这里用的是CentOS6.9
• nginx-1.12.1.tar源码包
• 安装开发包组,安装命令 yum groupinstall " Development tools"
• 安装上传下载插件,

编译安装

• 如果你电脑的源配好了,接下就开始安装pcre库
• pcre库是为了使Nginx支持具备URI重写功能的rewrite模块,也是他的依赖包
• 如果不安装则无法使用rewrite模块功能,Nginx的rewrite功能这是企业应用必须的,接下我们开始安装

[root@localhost ~]# yum install pcre-devel pcre -y

• 在用rpm -qa查看下,是否安装成功

[root@localhost ~]# rpm -qa pcre pcre-devel
pcre-7.8-7.el6.x86_64
pcre-devel-7.8-7.el6.x86_64

• 接下来安装openssl-devel

[root@localhost ~]# yum  install openssl openssl-devel -y

• 还是一样用rpm -qa来查看下

[root@localhost ~]# rpm -qa openssl openssl-devel 
openssl-1.0.1e-57.el6.x86_64
openssl-devel-1.0.1e-57.el6.x86_64

• 在创建用户

useradd  nginx -s /sbin/nologin -M

• 依赖包安装完毕以后,我们就开始把准备好的源代码包导入进去
• 可以用rz命令来上传,我上传的是在家目录里面

[root@localhost ~]# ls
anaconda-ks.cfg  install.log  install.log.syslog  nginx-1.12.1.tar.gz

• 接下来我们开始解压

[root@localhost ~]# tar xfv nginx-1.12.1.tar.gz 
nginx-1.12.1/
nginx-1.12.1/auto/
nginx-1.12.1/conf/
nginx-1.12.1/contrib/
nginx-1.12.1/src/
nginx-1.12.1/configure
nginx-1.12.1/LICENSE
nginx-1.12.1/README
nginx-1.12.1/html/
nginx-1.12.1/man/
nginx-1.12.1/CHANGES.ru
nginx-1.12.1/CHANGES
nginx-1.12.1/man/nginx.8
nginx-1.12.1/html/50x.html
nginx-1.12.1/html/index.html
nginx-1.12.1/src/core/
nginx-1.12.1/src/event/
nginx-1.12.1/src/http/
nginx-1.12.1/src/mail/
nginx-1.12.1/src/misc/

• 解压完毕以后,用cd命令切入进解压的文件里面

[root@localhost ~]# cd nginx-1.12.1

• ls来查看下

[root@localhost nginx-1.12.1]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src

• 做完了以后,我们就要开始编译了
• 但是在编译之前我要先给大家说说参数
• 在编译Nginx时,可以用./configure --help来查询相关参数
• 我们在这里要用到的参数是
  • --prefix=PATH set installation prefix : 指定安装路径
  • --user=USER set non-privileged user for :进程用户权限

  • --group=GROUP                      set non-privileged group for  :  进程用户组权限
    

  • --with-http_ssl_module:激活SSL功能
• 开始编译,命令有点长

[root@localhost nginx-1.12.1]#  ./configure  --user=nginx --group=nginx --prefix=/application/nginx --with-http_stub_status_module --with-http_ssl_module

• 出现下面图,表示编译成功,如果错误那是因为你没有安装依赖包,把上面的两个包安装即可

Configuration summary

  + using system OpenSSL library
  + using system zlib library

  nginx path prefix: "/application/nginx"
  nginx binary file: "/application/nginx/sbin/nginx"
  nginx modules path: "/application/nginx/modules"
  nginx configuration prefix: "/application/nginx/conf"

  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

• 接下来开始安装

[root@localhost nginx-1.12.1]# make && make install

• 出现下面情况表示安装成功

        || cp conf/uwsgi_params '/application/nginx/conf'
cp conf/uwsgi_params \
        '/application/nginx/conf/uwsgi_params.default'
test -f '/application/nginx/conf/scgi_params' \
        || cp conf/scgi_params '/application/nginx/conf'
cp conf/scgi_params \
        '/application/nginx/conf/scgi_params.default'
test -f '/application/nginx/conf/nginx.conf' \
        || cp conf/nginx.conf '/application/nginx/conf/nginx.conf'
cp conf/nginx.conf '/application/nginx/conf/nginx.conf.default'
test -d '/application/nginx/logs' \
        || mkdir -p '/application/nginx/logs'
test -d '/application/nginx/logs' \
        || mkdir -p '/application/nginx/logs'
test -d '/application/nginx/html' \
        || cp -R html '/application/nginx'
test -d '/application/nginx/logs' \
        || mkdir -p '/application/nginx/logs'
make[1]: Leaving directory `/root/nginx-1.12.1'

• 接下我们创建软连接

[root@localhost nginx-1.12.1]# ln   -s  /application/nginx-1.12.1  /application/nginx

• 让后就是启动了,但是启动前先检查下配置文件语法

[root@localhost nginx-1.12.1]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx/conf/nginx.conf syntax is ok
nginx: [emerg] getpwnam("nginx") failed
nginx: configuration file /application/nginx/conf/nginx.conf test failed

• 接下来就是启动服务

[root@localhost ~]# /application/nginx/sbin/nginx 

• 或者配置环境变量

vim /etc/profile.d/app.sh
export PATH=/app/httpd24/bin:$PATH

• 启动以后可以用ss -nutl来查看下80端口有没有打开

[root@localhost ~]# ss -nutl

• 让后去和你同一个网段的电脑,在游览器上输入你这台电脑的IP
• 出现下图就表示Nginx已经启动成功
