46day安装数据库 PHP

一，安装数据库

#1、创建用户

useradd mysql -s /sbin/nologin -M

#2、下载

cd /server/tools/

http://mirrors.163.com/mysql/Downloads/MySQL-5.7/

http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar

#3，解压，软连接

tar xf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

mkdir -p /application

mv mysql-5.7.26-linux-glibc2.12-x86_64 /application/mysql-5.7.26

ln -s /application/mysql-5.7.26/  /application/mysql

#4，卸载依赖包。

rpm -e --nodeps mariadb-libs

#5，配置文件/etc/my.cnf

touch /etc/my.cnf

cat>/etc/my.cnf<

[mysqld]

basedir = /application/mysql/

datadir = /application/mysql/data

socket = /tmp/mysql.sock

server_id = 1

port = 3306

log_error = /application/mysql/data/oldboy_mysql.err

[mysql]

socket = /tmp/mysql.sock

prompt = oldboy [\\d]>

EOF

#6，下载依赖包

yum install libaio-devel -y

#7，创建数据的文件

mkdir -p /application/mysql/data

chown -R mysql.mysql /application/mysql/

#8，初始化数据库

/application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql/ --datadir=/application/mysql/data

#9，配置启动服务

mkdir -p /etc/systemd/system/

cd /etc/systemd/system/

touch mysqld.service

cat>/etc/systemd/system/mysqld.service<

[Unit]

Description=MySQL Server by oldboy

Documentation=man:mysqld(8)

Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html

After=network.target

After=syslog.target

[Install]

WantedBy=multi-user.target

[Service]

User=mysql

Group=mysql

ExecStart=/application/mysql/bin/mysqld --defaults-file=/etc/my.cnf

LimitNOFILE = 5000

EOF

#10，启动数据库

cd /application/mysql/support-files

systemctl start mysqld

systemctl enable mysqld

#11，配置环境变量登录

echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile

. /etc/profile

#12，测试数据库

mysql

quit

===============================

#13，修改密码

mysqladmin -u root password 'oldboy123'

#交互式登录：

# [root@web02 ~]# mysql -uroot -p

# Enter password:

#非交互登录：

#mysql -uroot -poldboy123

二，PHP安装

/root/php.sh

#1、安装PHP调用的库

yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel -y

yum install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y

#2，下载libiconv-1.16.tar.gz

cd /server/tools/

上传libiconv-1.16.tar.gz

tar zxf libiconv-1.16.tar.gz

cd libiconv-1.16

./configure --prefix=/application/libiconv

make

make install

cd ../

yum install libmcrypt-devel -y

yum install mhash -y

yum install mcrypt -y

#3,安装PHP

cd /server/tools/

tar xf php-7.3.5.tar.gz

cd php-7.3.5/

./configure \

--prefix=/application/php-7.3.5 \

--enable-mysqlnd  \

--with-mysqli=mysqlnd \

--with-pdo-mysql=mysqlnd \

--with-iconv-dir=/application/libiconv \

--with-freetype-dir \

--with-jpeg-dir \

--with-png-dir \

--with-zlib \

--with-libxml-dir=/usr \

--enable-xml \

--disable-rpath \

--enable-bcmath \

--enable-shmop \

--enable-sysvsem \

--enable-inline-optimization \

--with-curl \

--enable-mbregex \

--enable-fpm \

--enable-mbstring \

--with-gd \

--with-openssl \

--with-mhash \

--enable-pcntl \

--enable-sockets \

--with-xmlrpc \

--enable-soap \

--enable-short-tags \

--enable-static \

--with-xsl \

--with-fpm-user=nginx \

--with-fpm-group=nginx \

--enable-ftp \

--enable-opcache=no

make

make install

#测试

#[root@web02 /server/tools/php-7.3.5]# echo $?

#4，将nginx的用户和PHP的用户统一：nginx

cd /server/tools/php-7.3.5

useradd nginx -u 1111 -s /sbin/nologin -M

#id nginx

#uid=1111(nginx) gid=1111(nginx) 组=1111(nginx)

cat >/application/nginx/conf/nginx.conf<

user  nginx nginx;

vim /application/nginx/conf/nginx.conf

worker_processes  1;

（编译的时候就改用nginx）

#5，配置php.ini（PHP解析器配置文件）

cd /server/tools/php-7.3.5/

#ls php.ini-*

#php.ini-development  php.ini-production

cp php.ini-development /application/php/lib/php.ini

# ls -l /application/php/lib/php.ini

#6、配置PHP FPM

cd /application/php/etc/

# ls

cp php-fpm.conf.default php-fpm.conf

cd php-fpm.d/

# ls

cp www.conf.default www.conf

# ls

=========================

cd /server/tools/php-7.3.5

useradd nginx -u 1111 -s /sbin/nologin -M

[root@web01 /server/tools]#ln -s php-7.3.5 /application/php

cd /server/tools/php-7.3.5/

cp php.ini-development /application/php/lib/php.ini

cd /application/php/etc/

cp php-fpm.conf.default php-fpm.conf

cd php-fpm.d/

cp www.conf.default www.conf

=======================

#7、启动PHP服务

/application/php/sbin/php-fpm

# netstat -lntup|grep php-fpm

#8、开机自启动

cat >>/etc/rc.local<

/application/nginx/sbin/nginx

/application/php/sbin/php-fpm

EOF

9，编写测试文件

[root@web02 /application/nginx/conf]# echo "" > ../html/blog/test_info.php

[root@web02 /application/nginx/conf]# cat ../html/blog/test_info.php

在浏览器里可以看到

三，测试PHP连接mysql

[root@web02 /application/nginx/html/blog]# cat  /application/nginx/html/blog/test_mysql.php

//$link_id=mysqli_connect('主机名','用户','密码');

$link_id=mysqli_connect('localhost','root','oldboy123') or mysql_error();

if($link_id){

echo "mysql successful by oldboy.\n";

}else{

echo mysql_error();

}

?>

[root@web02 /application/nginx/html/blog]# /application/php/bin/php /application/nginx/html/blog/test_mysql.php

mysql successful by oldboy.
