1、官网下载安装包

????,选择适合Linux的版本,这里选择最新的版本,下载到本地后上传到服务器或者centos下直接wget命令下载。

????切换到/usr/local目录,下载软件包

1

2

#?cd?/usr/local

#?wget?

2、安装nginx

先执行以下命令,安装nginx依赖库,如果缺少依赖库,可能会安装失败,具体可以参考文章后面的错误提示信息。

#?yum?install?gcc-c++

#?yum?install?pcre

#?yum?install?pcre-devel

#?yum?install?zlib?

#?yum?install?zlib-devel

#?yum?install?openssl

#?yum?install?openssl-devel

????解压安装包

1

#?tar?-zxvf?nginx-1.11.5.tar.gz

????nginx被解压到了/usr/local/nginx-1.11.5 目录下(不要把压缩包解压到/usr/local/nginx目录下,或者将解压后的目录重命名为nginx,因为nginx会默认安装到/usr/local/nginx目录下),切换到nginx-1.11.5/目录

1

#?cd?/usr/local/nginx-1.11.5/

????执行# ./configure

1

#?./configure

????该操作会检测当前系统环境,以确保能成功安装nginx,执行该操作后可能会出现以下几种提示:

????checking for OS

?????+ Linux 3.10.0-123.el7.x86_64 x86_64

????checking for C compiler ... not found

????./configure: error: C compiler cc is not found

????如果出现以上错误提示信息,执行yum install gcc-c++安装gcc,

????./configure: error: the HTTP rewrite module requires the PCRE library.

????You can either disable the module by using --without-http_rewrite_module

????option, or install the PCRE library into the system, or build the PCRE library

????statically from the source with nginx by using --with-pcre= option.

????如果出现上面提示,表示缺少PCRE库

????./configure: error: the HTTP gzip module requires the zlib library.

????You can either disable the module by using --without-http_gzip_module

????option, or install the zlib library into the system, or build the zlib library

????statically from the source with nginx by using --with-zlib= option.

????如果出现以上提示,表示缺少zlib库

?

????如果没有出现./configure: error提示,表示当前环境可以安装nginx,执行make和make install编译nginx

1

2

#?make

#?make?install

????没有出错的话,表示nginx已经成功安装完成,默认安装位置为/usr/local/nginx,之前的/usr/local/nginx-1.11.5/可以删除掉了。

????如果出现cp: 'conf/koi-win' and '/usr/local/nginx/conf/koi-win' are the same file,可能是你把安装包解压到了/usr/local/nginx目录,解决办法是将该目录重命名为其他名称后再执行make,make install.

3、配置nginx开机启动

????切换到/lib/systemd/system/目录,创建nginx.service文件vim nginx.service

1

2

#?cd?/lib/systemd/system/

#?vim?nginx.service

文件内容如下:

ExecStop=/usr/local/nginx/sbin/nginx?quit

[Install]?

WantedBy=multi-user.target

????退出并保存文件,执行systemctl enable nginx.service使nginx开机启动

1

#?systemctl?enable?nginx.service

systemctl start nginx.service????启动nginx

systemctl stop nginx.service????结束nginx

systemctl restart nginx.service????重启nginx

4、验证是否安装成功

????输入服务器IP/?如果能看到nginx的界面,就表示安装成功了
