Nginx安装

一、环境

操作系统：CentOS Linux release 7.3.1611 (Core)
nginx版本：nginx-1.14.0
其他依赖(下载地址见文末)： openssl-1.1.1-pre9.tar.gz pcre-8.38.tar.gz zlib-1.2.11.gz
文件结构：在/opt/nginx文件夹下使用指令tree -f -L 1

nginx
├── nginx/nginx-1.14.0
├── nginx/openssl-1.1.1-pre9
├── nginx/openssl-1.1.1-pre9.tar.gz
├── nginx/pcre-8.38
├── nginx/pcre-8.38.tar.gz
├── nginx/zlib-1.2.11
└── nginx/zlib-1.2.11.gz

二、预安装

安装系统自带依赖：

[root@ch-nginx ~] yum install -y gcc gcc-c++
[root@ch-nginx ~] yum install pcre-devel.x86-64
[root@ch-nginx ~] yum install zlib-devel.x86-64
[root@ch-nginx ~] yum install openssl-devel.x86-64

创建相应目录：

[root@ch-nginx ~] mkdir /usr/local/pcre
[root@ch-nginx ~] mkdir /usr/local/openssl
[root@ch-nginx ~] mkdir /usr/local/zlib
[root@ch-nginx ~] mkdir /usr/local/nginx

三、安装

1.安装pcre

[root@ch-nginx ~] cd /opt/nginx/pcre-8.38
[root@ch-nginx pcre-8.38] ./configure --prefix=/usr/local/pcre
[root@ch-nginx pcre-8.38] make && make install

2.安装openssl

[root@ch-nginx ~] cd /opt/nginx/openssl-1.1.1-pre9
[root@ch-nginx openssl-1.1.1-pre9] ./config --prefix=/usr/local/openssl
[root@ch-nginx openssl-1.1.1-pre9] make && make install

3.安装zlib

[root@ch-nginx ~] cd /opt/nginx/zlib-1.2.11
[root@ch-nginx zlib-1.2.11] ./configure --prefix=/usr/local/zlib
[root@ch-nginx zlib-1.2.11] make && make install

4.安装nginx

[root@ch-nginx ~] cd /opt/nginx/nginx-1.14.0
[root@ch-nginx nginx-1.14.0] ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-zlib=/opt/nginx/zlib-1.2.11 --with-openssl=/opt/nginx/openssl-1.1.1-pre9 --with-stream 
[root@ch-nginx nginx-1.14.0] make && make install

./configure --prefix=/usr/local/nginx表示安装到/usr/local/nginx目录下面

5.启动nginx

[root@ch-nginx nginx-1.14.0] /usr/local/nginx/sbin/nginx

6.检查nginx是否安装成功

[root@ch-nginx ~]# ps -ef|grep nginx
root     22596     1  0 17:24 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody   22616 22596  0 17:27 ?        00:00:00 nginx: worker process
root     22685   874  0 17:55 pts/0    00:00:00 grep --color=auto nginx

7. 开启80端口

停止防火墙
[root@ch-nginx ~] service iptables stop
或是把 80 端口加入到的排除列表：
[root@ch-nginx ~] iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
[root@ch-nginx ~] service iptables save
[root@ch-nginx ~] service iptables restart

四、nginx相关指令

• 启动：/usr/local/nginx/sbin/nginx
• 检查 Nginx 是否启动并监听了 80 端口：netstat -ntulp | grep 80
• 检查 Nginx 启用的配置文件是哪个：/usr/local/nginx/sbin/nginx -t
• 刷新 Nginx 配置后重启：/usr/local/nginx/sbin/nginx -s reload
• 停止 Nginx：/usr/local/nginx/sbin/nginx -s stop
