linux下安装nginx【https://www.cnblogs.com/xxoome/p/5866475.html】
Linux的版本【CentOS7 64位】
1、在安装nginx前首先要确认系统中安装了gcc、pcre-devel、zlib-devel、openssl-devel。
Linux下检查是否安装过某软件包：http://www.cnblogs.com/xxoome/p/5866553.html
安装命令：
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel
2、下载nginx安装包
wget http://nginx.org/download/nginx-1.12.2.tar.gz
3、解压安装包
tar -zxvf nginx-1.12.2.tar.gz
4、进入nginx目录
cd nginx-1.12.2
5、执行配置
/configure --prefix=/usr/local/nginx
6、编译安装(默认安装在/usr/local/nginx)
make&&makeinstall
7、测试是否安装成功
# cd到刚才配置的安装目录/usr/loca/nginx/
执行 ./sbin/nginx -t
错误信息：
nginx: [alert] could not open error log file: open() "/usr/local/nginx/logs/error.log" failed (2: No such file or directory)
2016/09/13 19:08:56 [emerg] 6996#0: open() "/usr/local/nginx/logs/access.log" failed (2: No such file or directory)
原因分析：nginx/目录下没有logs文件夹
解决方法：
mkdir logs
chmod 700logs
正常情况的信息输出：
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
启动nginx
cd /usr/local/nginx/sbin
./nginx//启动nginx
