1.下载地址：
http://nginx.org/en/download.html

# cd /usr/local
# wget http://nginx.org/download/nginx-1.11.5.tar.gz

 

2.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

 

3.解压安装包

# tar -zxvf nginx-1.11.5.tar.gz

 

4.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

# cd /usr/local/nginx-1.11.5/

 

5.执行# ./configure

# ./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

    1.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=<path> option.

    2.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=<path> option.

    3.如果出现以上提示，表示缺少zlib库

    

 

6.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

# 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。

 

7.配置nginx开机启动

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

# cd /lib/systemd/system/
# vim nginx.service

 

文件内容如下：

[Unit]
Description=nginx 
After=network.target 
   
[Service] 
Type=forking 
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx reload
ExecStop=/usr/local/nginx/sbin/nginx quit
PrivateTmp=true 
   
[Install] 
WantedBy=multi-user.target

 

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

# systemctl enable nginx.service
