1、gcc安裝
檢視是否有gcc
gcc -v
沒有需要安裝gcc，執行以下命令
yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake
yum -y install wget httpd-tools vim
檢視gcc -v 若報 comand not found,再執行
yum -y install gcc automake autoconf libtool make
cc -v檢視能看到版本
gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)

2、PCRE庫安裝
yum install pcre pcre-devel

3、zlib庫安裝
yum install zlib zlib-devel

4、OpenSSL庫安裝
yum install openssl openssl-devel

期間可能遇到以下錯誤：
若報錯如下：
make: * No rule to make target build', needed bydefault’. Stop.

說明有依賴庫沒安裝 ，繼續安裝上述幾個庫。

另外上述幾個庫安裝過程中，可能報如下錯誤
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

     1. You have an upgrade for zlib which is missing some
        dependency that another package requires. Yum is trying to
        solve this by installing an older version of zlib of the
        different architecture. If you exclude the bad architecture
        yum will tell you what the root cause is (which package
        requires what). You can try redoing the upgrade with
        --exclude zlib.otherarch ... this should give you an error
        message showing the root cause of the problem.

     2. You have multiple architectures of zlib installed, but
        yum can only see an upgrade for one of those architectures.
        If you don't want/need both architectures anymore then you
        can remove the one with the missing update and everything
        will work.

     3. You have duplicate versions of zlib installed already.
        You can use "yum check" to get yum show these errors.

   ...you can also use --setopt=protected_multilib=false to remove
   this checking, however this is almost never the correct thing to
   do as something else is very likely to go wrong (often causing
   much more problems).
 

上述常見原因是有兩個版本的庫。

用以下命令檢視zlib庫：
[[email protected]_0_14_centos ~]# rpm -qa | grep zlib
zlib-1.2.7-15.el7.i686
zlib-1.2.7-15.el7.x86_64

然後用以下命令刪除其中一個版本
[[email protected]_0_14_centos ~]# yum erase zlib-1.2.7-15.el7.i686

假設你上述庫都安裝完成後

5、到 usr/local目錄下下週nginx安裝包進行安裝，建議安裝在改目錄下，否則在全域性下沒有nginx命令，需要加軟連線，用該命令解決，加入你沒安裝在usr/local下，後者為你的安裝目錄
[[email protected]_0_14_centos nginx-1.14.0]# /usr/local/nginx/sbin/nginx -c /root/nginx-1.14.0/conf/nginx.conf

6、安裝步驟：分別執行以下命令
wget http://nginx.org/download/nginx-1.1.10.tar.gz
tar -zxvf nginx-1.1.10.tar.gz
cd nginx-1.1.10
./configure
make
make install

7、修改nginx配置
到nginx安裝目錄下，用vim 開啟命令開啟nginx.conf
因為可能apeache佔用80埠，apeache埠儘量不要修改，我們選擇修改nginx埠。
開啟後server中的listen是監聽的埠 預設80，修改為8090 或者你想要的埠。

最後一步

8、啟動nginx
nginx -s reload

然後至瀏覽器中檢視是否啟動好，貼上我的圖
