云计算 3月8号 （wordpress的搭建）

项目wordpress

实验目的：

熟悉yum和编译安装操作

锻炼关联性思维，便于以后做项目

nginx 编译安装

1、安装源码包

[root@linux-server ~]# yum -y install gcc make zlib-devel pcre pcre-devel openssl-devel
[root@linux-server ~]# wget http://nginx.org/download/nginx-1.16.1.tar.gz
[root@linux-server ~]# tar xzf nginx-1.16.1.tar.gz

2、编译安装

[root@linux-server nginx-1.16.1]# ./configure --user=www --group=www --prefix=/usr/local/nginx
[root@linux-server nginx-1.16.1]# make  #编译文件
[root@linux-server nginx-1.16.1]# make install  #安装文件
​

3、nginx 操作

[root@linux-server ~]# useradd www   #创建nginx用户
[root@linux-server ~]# /usr/local/nginx/sbin/nginx  #启动nginx
[root@linux-server ~]# systemctl stop firewalld  #关闭防火墙
​
停止nginx
[root@linux-server nginx-1.16.1]# /usr/local/nginx/sbin/nginx -s stop

4、访问

mysql 编译安装

1、清理安装环境

# systemctl stop mariadb mysqld
# yum erase mariadb mariadb-server mariadb-libs mariadb-devel -y
# userdel -r mysql
# rm -rf /etc/my*
# rm -rf /var/lib/mysql

2、创建mysql用户

[root@mysql-server ~]# useradd -r mysql -M -s /bin/nologin
-M 不创建用户的家目录

3、从官网下载tar包

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.27.tar.gz

4、安装编译工具

# 请确保yum源可以用 [base|epel]
# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make cmake

5、创建mysql目录

[root@mysql-server ~]# mkdir -p /usr/local/{data,mysql,log}

6、解压

[root@mysql-server ~]# tar xzvf mysql-boost-5.7.27.tar.gz

7、编译安装

cd 解压的mysql目录
[root@mysql-server ~]# cd mysql-5.7.27/
[root@mysql-server mysql-5.7.27]# cmake . \
-DWITH_BOOST=boost/boost_1_59_0/ \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DSYSCONFDIR=/etc \
-DMYSQL_DATADIR=/usr/local/data \
-DINSTALL_MANDIR=/usr/share/man \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1
​

[root@mysql-server mysql-5.7.27]# make && make install
如果安装出错，想重新安装：
    不用重新解压，只需要删除安装目录中的缓存文件CMakeCache.txt

**需要很长时间！**大约半小时

8、初始化

[root@mysql-server mysql-5.7.27]# cd /usr/local/mysql
[root@mysql-server mysql]# chown -R mysql.mysql .
[root@mysql-server mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/data     ---初始化完成之后，一定要记住提示最后的密码用于登陆或者修改密码

初始化,只需要初始化一次

[root@mysql-server ~]# vim /etc/my.cnf    ---如果打开文件有内容将文件中所有内容注释掉，在添加如下内容
[mysqld]
basedir=/usr/local/mysql     #指定安装目录
datadir=/usr/local/data  #指定数据存放目录

9、启动mysql

[root@mysql-server ~]# cd /usr/local/mysql
[root@mysql-server mysql]# ./bin/mysqld_safe --user=mysql &
​
启动之后再按一下回车！即可后台运行

10、systemctl启动方式

• 拷贝启动脚本到/etc/init.d/目录下，并改名mysqld

[root@qfedu.com mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@qfedu.com mysql]# ls -l /etc/init.d/mysqld
-rwxr-xr-x 1 root root 10588 Aug 1 18:33 /etc/init.d/mysqld

• 重新加载系统服务

[root@localhost mysql]# systemctl daemon-reload

• 启动MySQL数据库，并检查端口监听状态

[root@localhost mysql]# systemctl stop mysqld   --停止mysqld
# 或者
[root@localhost mysql]# systemctl start mysqld  --启动mysqld
Starting MySQL. SUCCESS! 
​
[root@localhost mysql]# netstat -lntp | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      16744/mysqld

11、创建密码并修改数据库

[root@mysql-server mysql]# /usr/local/mysql/bin/mysql -uroot -p'GP9TKGgY9i/8'
mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.

yum安装php

[root@mysql-server ~]# yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
[root@mysql-server ~]# yum install php80-php-xsl php80-php php80-php-cli php80-php-devel php80-php-gd php80-php-pdo php80-php-mysql php80-php-fpm -y
[root@mysql-server ~]# systemctl start php80-php-fpm

测试各软件

[root@localhost ~]# ss -tnlp | grep -P ":80|:3306|:9000"
LISTEN     0      128          *:80                       *:*                   users:(("nginx",pid=121623,fd=6),("nginx",pid=94310,fd=6))
LISTEN     0      128    127.0.0.1:9000                     *:*                   users:(("php-fpm",pid=123775,fd=9),("php-fpm",pid=96348,fd=9),("php-fpm",pid=96347,fd=9),("php-fpm",pid=96346,fd=9),("php-fpm",pid=96345,fd=9),("php-fpm",pid=96344,fd=9),("php-fpm",pid=96343,fd=7),("php-fpm",pid=11326,fd=9),("php-fpm",pid=10570,fd=9))
LISTEN     0      80        [::]:3306                  [::]:*                   users:(("mysqld",pid=71720,fd=28))
​

代码上线

1、拷贝代码包到系统并解压

2、拷贝到nginx项目目录

rm -rf /usr/local/nginx/html/*
cp -r wordpress/* /usr/local/nginx/html/

3、修改配置并重启

vim /usr/local/nginx/conf/nginx.conf
# 修改nginx配置，删除35-79行内容，添加php后端，并重启nginx
# nginx 配置文件设置
server {
        listen      80;
        server_name _;
        location / {
            root html;
            index index.php;
        }
        location ~ \.php$ {
            root          html;  #指定网站目录
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; 
            include        fastcgi_params;
                }
        }
/usr/local/nginx/sbin/nginx -s reload
