今天安裝 Nginx出現如下報錯：

yum install zlib

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).
       
       Protected multilib versions: zlib-1.2.7-17.el7.x86_64 != zlib-1.2.7-15.el7.i686
 

多個庫不能共存，解決方法，執行時新增以下引數即可：

yum install -y zlib zlib-devel --setopt=protected_multilib=false

安裝Nginx：

1、安裝依賴：

yum install gcc

yum install pcre-devel

yum install zlib zlib-devel

yum install openssl openssl-devel

//一次性裝以上四個依賴
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
 

2、新建安裝目錄，下載Nginx到nginx目錄並解壓：

mkdir /usr/local/nginx

wget http://nginx.org/download/nginx-1.14.0.tar.gz

tar -zxvf nginx-1.14.0.tar.gz

3、檢查編譯安裝

./configure --prefix=/usr/local/nginx

make

make install

4、進入sbin目錄，啟動nginx，即可訪問80埠預設頁面：

[[email protected]_4_84_centos sbin]# pwd
/usr/local/nginx/sbin
[[email protected]
 
_4_84_centos sbin]# ./nginx
[[email protected]_4_84_centos sbin]# ps -ef | grep nginx
