安装前准备工作

因为Nginx依赖于gcc的编译环境，所以，需要安装编译环境来使Nginx能够编译起来

yum install gcc-c++

Nginx的http模块需要使用pcre来解析正则表达式，需要安装pcre

yum install -y pcre pcre-devel

安装依赖的解压包

yum install -y zlib zlib-devel

ssl 功能需要 openssl 库，安装 openssl

yum install -y openssl openssl-devel

下载Nginx

可以自己建立一个包，将nginx下载到这个路径，我设置的路径/opt/crm/nginx
如果需要其他nginx版本的可以参考 nginx仓库

wget http://nginx.org/download/nginx-1.10.2.tar.gz

下载完之后解压

tar zxvf nginx-1.10.2.tar.gz

进入到解压之后的nginx目录

[root@localhost src]# cd nginx-1.10.2
[root@localhost nginx-1.10.2]# ./configure && make && make install

如果要使用ssl

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

注意：如果配置了ssl，检查配置文件时报错

nginx -t
nginx:[emerg]unknown directive ssl错误

去到nginx安装的目录
./configure --with-http_ssl_module

注意要把新生成的文件复制到对应目录
cp objs/nginx /usr/local/nginx/sbin/nginx

显示成功就搞定
[root@iZ2ze02hshpth1x0vxo8r6Z sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@iZ2ze02hshpth1x0vxo8r6Z sbin]# 

安装完之后查看安装目录

[root@izbp10k7vskcf4soxxbp5gz /]# whereis nginx
nginx: /usr/local/nginx
[root@izbp10k7vskcf4soxxbp5gz /]# 

通过查找文件名方式

[root@izbp10k7vskcf4soxxbp5gz /]# find / -name nginx
/opt/crm/nginx
/opt/crm/nginx/nginx-1.10.2/objs/nginx
/usr/local/nginx
/usr/local/nginx/sbin/nginx
[root@izbp10k7vskcf4soxxbp5gz /]# 

直接执行

[root@izbp10k7vskcf4soxxbp5gz /]# /usr/local/nginx/sbin/nginx
[root@izbp10k7vskcf4soxxbp5gz /]# ps -ef | grep nginx
root      4666     1  0 09:32 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody    4667  4666  0 09:32 ?        00:00:00 nginx: worker process
root      5028 29443  0 09:40 pts/0    00:00:00 grep --color=auto nginx
[root@izbp10k7vskcf4soxxbp5gz /]# 

在浏览器输入服务器IP地址

增加systemctl命令方式启动

直接启动和关闭nginx的方式

启动nginx的命令为     /usr/local/nginx/sbin/nginx  
停止nginx的命令为    /usr/local/nginx/sbin/nginx -s stop
重启nginx的命令为    /usr/local/nginx/sbin/nginx -s reload

配置方式 去到/usr/lib/systemd/system/目录新建一个nginx服务，给予执行权限

vim /usr/lib/systemd/system/nginx.service
chmod +x /usr/lib/systemd/system/nginx.service

打开文件nginx.service新建内容

[Install]
WantedBy=multi-user.target 

保存之后重载Ststemctl命令

在启动服务之前，需要先重载systemctl命令
systemctl daemon-reload

配置完之后

systemctl status nginx
systemctl start nginx
systemctl stop nginx
systemctl restart nginx

附上配置
