• centos7 下安装apache mysql php phpmyadmin。


    1 安装mysql 

    yum -y install mariadb-server

    systemctl start mariadb.service

    systemctl enable mariadb.service

    mysql_secure_installation

      默认安装的是5.5.40-MariaDB ,个人喜欢的版本,不再是5.1的那个了。

      

    2 安装apache 

     

    yum install -y httpd
    systemctl start httpd.service
    systemctl enable httpd.service

    apache 版本为 2.4.6 

    3 .安装php

    yum -y install php
    systemctl restart httpd.service
    

      php5.4 

    4.安装phpmyadmin 

    这里直接用 yum install phpmyadmin  ,前提是epel 源已经被配置好了。

    /etc/httpd/conf.d 下多了一个  phpMyAdmin.conf 的配置文件。

    这里多了一个访问控制 

    <Directory /usr/share/phpMyAdmin/>
    AddDefaultCharset UTF-8

    <IfModule mod_authz_core.c>
    # Apache 2.4
    <RequireAny>
    Require ip 114.88.5.47
    Require ip 127.0.0.1
    Require ip ::1
    </RequireAny>
    </IfModule>
    <IfModule !mod_authz_core.c>
    # Apache 2.2
    Order Deny,Allow
    Deny from All
    Allow from 127.0.0.1
    Allow from ::1
    </IfModule>
    </Directory>

      也可以看出来,httpd 2.2和2.4是不同的。

    5. 其他

      其实安装和centos6的版本没啥区别。做了一些软件的升级,但是在启动上面,废弃了原先的/etc/init.d 下面的bash 脚本。而是用了systemctl 这个命令。

      相关文件都在 /usr/lib/systemd/system 下面了。看了一下,比之前的bash 脚本简单好多。比如httpd的systemctl文件  

    cat /usr/lib/systemd/system/httpd.service 
    [Unit]
    Description=The Apache HTTP Server
    After=network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=notify
    EnvironmentFile=/etc/sysconfig/httpd
    ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND
    ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
    ExecStop=/bin/kill -WINCH ${MAINPID}
    # We want systemd to give httpd some time to finish gracefully, but still want
    # it to kill httpd after TimeoutStopSec if something went wrong during the
    # graceful stop. Normally, Systemd sends SIGTERM signal right after the
    # ExecStop, which would kill httpd. We are sending useless SIGCONT here to give
    # httpd time to finish.
    KillSignal=SIGCONT
    PrivateTmp=true
    
    [Install]
    WantedBy=multi-user.target
    

      还是之前的chkconfig  ,也集成在systemctl中了。 很简洁 systemctl enable  httpd  

    systemctl enable  httpd
    ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
    

      

      做的操作其实是一个软连接。很直观。操作什么直接反馈回来了。

    [root@iZ23f0gpuenZ _local]# systemctl status  httpd
    httpd.service - The Apache HTTP Server
       Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)
       Active: inactive (dead)

    Dec 14 14:49:34 iZ23f0gpuenZ systemd[1]: Started The Apache HTTP Server.

    Dec 14 14:50:24 iZ23f0gpuenZ systemd[1]: Started The Apache HTTP Server.

    Dec 14 15:37:50 iZ23f0gpuenZ systemd[1]: Stopped The Apache HTTP Server.
    Hint: Some lines were ellipsized, use -l to show in full.
    

      status 也做的很hi ,什么时候操作过httpd 的服务也一目了然。

      centos 7 还做了进一步的升级,比如说加入了firewall ,内置了git 等,做了很实用的升级。更多功能正在摸索中。
