nginx1.12配置

1.创建一个用户，不能登录和不创建主目录

useradd -s /sbin/nologin  -M nginx

1.1安装依赖关系

yum install gc gcc gcc-c++ pcre-devel zlib-devel openssl-devel

2.下载nginx包

wget -C http://nginx.org/download/nginx-1.12.0.tar.gz

2.1 解压

tar zxvf nginx-1.12.0.tar.gz

2.2 编译设置

cd nginx-1.12.0

./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module

若出现错误主要有一下几点：

如果有错误提示：./configure: error: C compiler cc is not found

解决：

yum install gcc gcc-c++

如果有错误提示：./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.

解决：

yum install gcc gcc-c++

如果有错误提示：./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using –with-openssl=<path> option.

解决：

yum install openssl-devel

2.3 编译安装

make

make install

4.nginx启动以及查看是否成功

cd /usr/local/nginx/sbin/

./nginx    启动
./nginx -s stop  停止
./nginx -s reload 加载配置文件

查看端口是否开启

netstat -tanlp |grep 80

 5.添加脚本启动

cd /lib/systemd/system

vim nginx.service
