• 环境：Centos 7.2
• nginx版本：1.11.5

下载Nginx

mkdir -p /opt/module
cd /opt/module
wget http://nginx.org/download/nginx-1.11.5.tar.gz

我们将nginx下载到/opt/module目录下

安装Nginx

1. 安装依赖

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

2. 解压nginx

cd /opt/module
tar -zxvf nginx-1.11.5.tar.gz

3. 安装nginx

cd /opt/module/nginx-1.11.5/
./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=<path> 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=<path> 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

4. 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/opt/module/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.

配置开机启动

1. 配置启动文件

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

# 将以下文件内容粘贴进去
[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. 加载配置文件

# 记得保存上面的nginx.service文件

#使nginx开机启动
systemctl enable nginx.service

常用命令

nginx默认是装在/usr/local/nginx目录下，日志也在该目录下。

systemctl start nginx.service    启动nginx
systemctl stop nginx.service    结束nginx
systemctl restart nginx.service    重启nginx

可以直接访问ip查看nginx启动情况，输入http://服务器IP/ 如果能看到nginx的界面，就表示安装成功了。
