CentOS7下nginx + php7 + mariadb +wordpress 的安装

热度:79   发布时间:2023-12-22 07:15:48.0

z在一般的运维中,都是需要安装nginx + php + mariadb数据库。注意 mariadb 实际上是mysqlserver的社区版本。功能基本上一样。从ubuntu到centos7 ,目前基本上不提供mysqlserver版本,只提供mariadb版本。

环境

centos7.8 ,192.168.137.104,内存2g

确保系统已经停用selinux 和防火墙

命令分别是.

setenforce 0
systemctl stop firewalld

如果永久性的停用这2个功能,采用如下方法

sed -i 's/eforcing/disabled/g /etc/selinux/config  && reboot
systemctl disable firewalld

安装mariadb

首先我们搜索下yum仓库上有哪些mariadb数据库。

[root@lamp ~]# yum list |grep mariadb
mariadb-libs.x86_64                         1:5.5.65-1.el7             @anaconda
mariadb.x86_64                              1:5.5.65-1.el7             base     
mariadb-bench.x86_64                        1:5.5.65-1.el7             base     
mariadb-devel.i686                          1:5.5.65-1.el7             base     
mariadb-devel.x86_64                        1:5.5.65-1.el7             base     
mariadb-embedded.i686                       1:5.5.65-1.el7             base     
mariadb-embedded.x86_64                     1:5.5.65-1.el7             base     
mariadb-embedded-devel.i686                 1:5.5.65-1.el7             base     
mariadb-embedded-devel.x86_64               1:5.5.65-1.el7             base     
mariadb-libs.i686                           1:5.5.65-1.el7             base     
mariadb-server.x86_64                       1:5.5.65-1.el7             base     
mariadb-test.x86_64                         1:5.5.65-1.el7             base 

我们选取 mariadb-server.x86_64进行安装

[root@lamp ~]# yum -y install  mariadb-server.x86_64

启动服务器并且连接数据库,低版本的mariadb的root账户默认密码是空,高版本的可能要到日志里去看数据库的root的密码。这里的密码是空

[root@lamp ~]# systemctl start mariadb
[root@lamp ~]# mysql -uroot -p
Enter password:

安装nginx

首先增加nginx的库,默认的话centos7 是找不到直接安装包的。


[root@lamp ~]# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
Retrieving http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

Updating / installing...1:nginx-release-centos-7-0.el7.ngx ################################# [100%]

然后安装nginx 

[root@lamp ~]# yum -y  install nginx
Loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-managerResolving Dependencies
--> Running transaction check
---> Package nginx.x86_64 1:1.18.0-1.el7.ngx will be installed

安装成功。

启动nginx: systemctl start nginx

浏览器中直接访问可以看到安装成功。

 

安装php7

centos7默认安装php5,安装是比较方便,但因为太老,我们尝试安装php7。默认的centos7 yum库是不带 php7的源。

1.安装epel-release
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm2.安装PHP7的rpm源
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm3.安装PHP7
yum -y install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64

如果需要安装php-fpm在后台运行,还需要安装如下的包

yum -y install php70w-fpm php70w-opcache

正常情况下安装成功。如果出现错误,可以留言在评论区。 

启动php-fpm

systemctl start php-fpm

开机启动设置

systemctl enable php-fpm
systemctl daemon-reload

 查看端口9000是不是已经启动,netstat -an |grep 9000,如果启动就算成功。

[root@lamp ~]# netstat -an |grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN

成功!

配置nginx和php

首先创建一个文件,实际上nginx的默认根目录是在/usr/share/nginx/html,我们

# cat <<EOF >/usr/share/nginx/html/phpinfo.php
<?php phpinfo();
?>
EOF

配置nginx,yum安装后的nginx默认的配置文件在/etc/nginx/nginx.conf,该文件中指明了当前conf.d中文件为模块的配置文件。安装之后有一个文件default.conf. 直接修改/etc/nginx/conf.d/default.conf.

[root@lamp conf.d]# vi default.conf 
server {listen       80;server_name  localhost;#charset koi8-r;#access_log  /var/log/nginx/host.access.log  main;location / {root   /usr/share/nginx/html;index  index.html index.htm index.php;}#error_page  404              /404.html;# redirect server error pages to the static page /50x.html#error_page   500 502 503 504  /50x.html;location = /50x.html {root   /usr/share/nginx/html;}# proxy the PHP scripts to Apache listening on 127.0.0.1:80##location ~ \.php$ {#    proxy_pass   http://127.0.0.1;#}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000##location ~ \.php$ {#    root           html;#    fastcgi_pass   127.0.0.1:9000;#    fastcgi_index  index.php;#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;#    include        fastcgi_params;#}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one##location ~ /\.ht {#    deny  all;#}
}

我们把有关php配置的#去掉,#在配置文件中表示注释。

server {listen       80;server_name  localhost;#charset koi8-r;access_log  /var/log/nginx/host.access.log  main;location / {root   /usr/share/nginx/html;index  index.html index.htm index.php;}#error_page  404              /404.html;# redirect server error pages to the static page /50x.html#error_page   500 502 503 504  /50x.html;location = /50x.html {root   /usr/share/nginx/html;}# proxy the PHP scripts to Apache listening on 127.0.0.1:80##location ~ \.php$ {#    proxy_pass   http://127.0.0.1;#}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000#location ~ \.php$ {
#修改1root   /usr/share/nginx/html;fastcgi_pass   127.0.0.1:9000;fastcgi_index  index.php;
#修改2fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;include        fastcgi_params;}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one#location ~ /\.ht {deny  all;}
}

测试:

安装wordpress

首先找到wordpress的源代码,可以到这里下载  https://cn.wordpress.org/latest-zh_CN.tar.gz

使用wget下载完,解压,并复制到/usr/share/nginx/html中。

[root@lamp ~]# ll
total 12576
-rw-------. 1 root root     1261 Sep  6 05:35 anaconda-ks.cfg
-rw-r--r--  1 root root 12872547 Oct  2 02:31 wordpress-5.4.2-zh_CN.tar.gz
[root@lamp ~]# tar zxf wordpress-5.4.2-zh_CN.tar.gz 
[root@lamp ~]# ls -l
total 12580
-rw-------. 1 root root     1261 Sep  6 05:35 anaconda-ks.cfg
drwxr-xr-x  5 1006 1006     4096 Aug  3 00:00 wordpress
-rw-r--r--  1 root root 12872547 Oct  2 02:31 wordpress-5.4.2-zh_CN.tar.gz

创建数据库给wordpress使用

[root@lamp ~]# mysql -uroot << EOF
> create database wordpress;
> EOF

拷贝完成以后直接在浏览器输入地址,访问,进入安装页面,如果没权限写入配置文件,请将/usr/share/nginx/html/wordpress 设置成属主为apache.

如果访问当中出现问题,请禁用seLinux权限控制和关闭防火墙

安装成功访问页面

 

在php-fpm和nginx不在同一台机器上的时候,这个段中的php,root的配置,是指在php-fpm的机器上的目录,如果放在单独的nginx的服务器上,是访问不到php文件的。

也就是说,如果nginx接收到访问PHP文件,nginx根本不读取php文件,而是直接把这个文件的路径和其他信息交个了php-fpm去处理了。所以这里的路径也是指php在php-fpm上的路径。

 location ~ \.php$ {root   /usr/share/nginx/html;fastcgi_pass   dkphpfpm7:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;include        fastcgi_params;}
