nginx安装
一、官网yum安装方法
$ sudo vi /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
$ sudo yum install nginx
二、安装包安装
1、安装编译工具及库文件
$ yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
2、安装PCRE库 $ yum install -y pcre pcre-devel
注:安装编译工具及库文件时pcre被依赖,已经安装了,使用$ yum list installed | grep pcre
查看。
PCRE(Perl Compatible Regular Expressions) 是一个Perl库,包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式,所以需要在 linux 上安装 pcre 库,pcre-devel 是使用 pcre 开发的一个二次开发库。nginx也需要此库。命令:
$ mkdir -p /usr/java
$ cd /usr/java
$ wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz
$ ./configure --prefix=/usr/java/pcre
$ make && make install
查看pcre版本
$ pcre-config --version
配置环境变量
3、安装nginx
$ mkdir -p /usr/java
$ cd /usr/java
$ wget http://nginx.org/download/nginx-1.14.2.tar.gz
$ tar -zxvf nginx-1.14.2.tar.gz
$ cd nginx-1.14.2
$ ./configure --prefix=/usr/java/nginx --with-http_stub_status_module --with-http_ssl_module
# --add-module=/usr/java/fastdfs-nginx-module/src #fastdfs和nginx整合模块
# --add-module=/usr/java/ngx_cache_purge #fastdfs集群需要用到
#--with-pcre=/usr/pcre #就用默认的,不指定自定义的pcre
$ make && make install
$ cd .. && rm -rf nginx-1.14.2
查看版本:$ /usr/java/nginx/sbin/nginx -v
启动:$ /usr/java/nginx/sbin/nginx
4、配置
参考:
5、服务脚本
$ vi /etc/init.d/nginx
