Nginx安装-Centos7（nginx安装ssl）

CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。

systemctl stop firewalld.service #停止firewall

systemctl disable firewalld.service #禁止firewall开机启动

yum install iptables-services #安装

vi /etc/sysconfig/iptables #编辑防火墙配置文件

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

*filter

:FORWARD ACCEPT [0:0]

COMMIT

:wq! #保存退出

systemctl restart iptables.service #最后重启防火墙使配置生效

systemctl enable iptables.service #设置防火墙开机启动

关闭SELINUX

vi /etc/selinux/config

#SELINUX=enforcing #注释掉

#SELINUXTYPE=targeted #注释掉

SELINUX=disabled #增加

:wq! #保存退出

setenforce 0 #使配置立即生效

1、进入nginx目录

[root@localhost nginx-1.11.2]# ls

auto CHANGES CHANGES.ru conf configure contrib html LICENSE Makefile man objs README src

然后执行 ./configure #主要的作用是对即将安装的软件进行配置，检查当前的环境是否满足要安装软件的依赖关系

[root@localhost nginx-1.11.2]# ./configure

checking for OS

+ Linux 3.10.0-327.el7.x86_64 x86_64

checking for C compiler ... not found

./configure: error: C compiler cc is not found

简单解释：Gcc编译器能将C、C++语言源程序、汇程式化序和目标程序编译、连接成可执行文件。

2、yum解决 yum install gcc

1）然后再次执行 ./configure

报错：./configure: error: the HTTP rewrite module requires the PCRE library.

PCRE是一个NFA正则引擎，不然不能提供完全与Perl一致的正则语法功能。但它同时也实现了DFA，只是满足数学意义上的正则。

yum install -y pcre pcre-devel

2）然后再次执行 ./configure

报错：./configure: error: the HTTP gzip module requires the zlib library.

libpng 是一套免费的、公开源代码的程序库，支持对 PNG 图形文件的创建、读写等操作。libpng 使用 zlib 程序库作为压缩引擎，zlib 也是著名的 gzip (GNU zip) 所采用的压缩引擎。

yum install -y zlib-devel

3)继续往下做缺少什么依赖就装即可 这里解决依赖 yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel ncurses ncurses-devel

gcc、gc++、make先下载到本地

3、安装

./configure \

–prefix=/usr/local/nginx \

–sbin-path=/usr/local/nginx/sbin/nginx \

–conf-path=/usr/local/nginx/conf/nginx.conf \

–error-log-path=/usr/local/nginx/logs/error.log \

–http-log-path=/usr/local/nginx/logs/access.log \

–pid-path=/usr/local/nginx/run/nginx.pid \

–lock-path=/usr/local/nginx/lock/nginx.lock \

–user=nginx \

–group=nginx \

–with-http_ssl_module \

–with-http_realip_module \

–with-http_stub_status_module \

–with-http_gzip_static_module \

–http-proxy-temp-path=/usr/local/nginx/tmp/nginx/proxy/ \

–http-fastcgi-temp-path=/usr/local/nginx/tmp/nginx/fcgi/ \

–http-uwsgi-temp-path=/usr/local/nginx/tmp/nginx/uwsgi

最后给出安装位置信息

make && make install

/usr/local/nginx/sbin/nginx -t #查看配置是否正确

useradd -M -s /sbin/nologin nginx

groupadd -f nginx

/usr/local/nginx/sbin/nginx -V #查看可编译选项，能找到安装路径信息

启动时一些命令：

nginx -t

#启动nginx

nginx

#说一下nginx启动的一些事情

#一般来说在nginx的配置文件修改后进行如下操作，nginx -t检测一下配置文件是否正确，如果正确的话

#再使用nginx -s reload 使nginx平滑启动

#把nginx添加到开机启动

vim /etc/rc.local

#在最后新加一行

/usr/local/nginx/sbin/nginx

#查看nginx是否启动

netstat -tunpl | grep 80

pstree 看下有没有nginx就行了
