Log_bin=mysql-bin

Log_bin_index=mysql-bin.index

Binlog_format=mixed

[mysqld_safe]

Log-error=/var/log/mysql.log

Pid-file=/var/run/mysql.pid

(14) initialize the MySQL database:

# / usr/local/mysql/bin/mysqld-defaults-file=/etc/my.cnf-initialize-user=mysql-basedir=/usr/local/mysql-datadir=/data/mysql

Note:

Make sure the / data/mysql directory is empty before initialization

B, MySQL version 5.7 no longer uses mysql_install_db when initializing the database, but uses mysqld-- initialize

C, parameter-- defaults-file=/etc/my.cnf should be placed first of all parameters

D. The initial password of the root@localhost user will be displayed

(15) configure MySQL environment variables:

# vim / etc/profile.d/mysql.sh

Export PATH=/usr/local/mysql/bin:$PATH

#. / etc/profile.d/mysql.sh

# mysql-V

# mysql-- help | less

(16) manage service processes through mysql.server:

# cp / usr/local/mysql/support-files/mysql.server / etc/init.d/mysqld

# chmod + x / etc/init.d/mysqld

# make & & make install

Note:

A. If Libzip is not compiled and installed, it will prompt "configure: error: Please reinstall the libzip distribution".

B. You need to compile and install CMake first. MySQL was already installed when you compiled and installed MySQL before.

(4) modify the ld.so.conf configuration file:

# vim / etc/ld.so.conf, add the following code:

/ usr/local/lib64

/ usr/local/lib

# make & & make install

Note: it takes a long time to compile and install

(6) create a php.ini configuration file: # cp / usr/src/php-7.3.9/php.ini-production / usr/local/php/etc/php.ini

(7) create a php-fpm.conf configuration file: # cp / usr/local/php/etc/php-fpm.conf.default / usr/local/php/etc/php-fpm.conf

Note: php-fpm,PHP FastCGI Process Manager,PHP FastCGI process Manager runs PHP as a stand-alone service through FastCGI

(8) create and modify www.conf configuration files:

# cd / usr/local/php/etc/php-fpm.d

# cp www.conf.default www.conf

# vim www.conf

Before modification

After modification

Listen = 127.0.0.1 9000

Listen = 192.168.0.1209000

(9) configure PHP environment variables:

# vim / etc/profile.d/php.sh

Export PATH=/usr/local/php/sbin:/usr/local/php/bin:$PATH

#. / etc/profile.d/php.sh

# php-v

# php-h | less

# php-fpm-h

(10) manage service processes through php-fpm.service: # cp / usr/src/php-7.3.9/sapi/fpm/php-fpm.service / usr/lib/systemd/system/

(11) start php-fpm:

# php-fpm-t

# systemctl start php-fpm.service

# systemctl status php-fpm.service

# ps aux | grep php-fpm

# ss-tunlp | grep 9000

# tail-100 / usr/local/php/var/log/php-fpm.log

(12) configure PHP to boot: # systemctl enable php-fpm.service

4. Nginx integrates PHP:

(1) modify the nginx.conf configuration file:

# cd / usr/local/nginx/conf

# vim nginx.conf

Worker_processes auto

Location / {

Root html

Index index.php index.html index.htm

}

Location ~\ .php$ {

Root html

Fastcgi_pass 192.168.0.120:9000

Fastcgi_index index.php

Fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name

Include fastcgi_params

}

# nginx-t

# nginx-s reload

(2) create a test page:

# vim / usr/local/nginx/html/index.php

Note: if you use the mysql_connect () function of the old version of PHP to connect to MySQL in the new version of PHP, you will be prompted with "undefined function mysql_connect ()". Since PHP version 5.5, MySQL has not recommended using the mysql_connect () function, which is an obsolete function. It is not supported at all in PHP 7, and the mysqli_connect () function has been added. In a sense, mysqli is the enhanced version of mysql system function, which is more stable, efficient and secure. It belongs to object-oriented and operates and drives MySQL database in an object-oriented way.

(3) browsers access http://192.168.0.120

Stop MySQL:# systemctl stop mysqld.service

Refresh the page:

3. Set up Zabbix:

1. Deploy Zabbix:

# cd / usr/local

# ln-sv jdk1.8.0_221 jdk

Note: if the-- enable-java option is enabled when compiling and installing Zabbix 4.2.6, you need to configure JDK

(4) configure JDK environment variables:

# vim / etc/profile.d/jdk.sh

Export JAVA_HOME=/usr/local/jdk

Export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Export PATH=$JAVA_HOME/bin:$PATH

#. / etc/profile.d/zabbix.sh

# ln-sv / usr/local/mysql/lib/libmysqlclient.so.20 / usr/lib64/libmysqlclient.so.20

Note: do not perform this step, "zabbix_server: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory" will be prompted when executing the # zabbix_server-- version command

# zabbix_server-version

# zabbix_server-h | less

2. Configure Zabbix:

(1) Log in to MySQL, create zabbix database and 'zabbix'@'192.168.0.%' user, and authorize' zabbix'@'192.168.0.%' user to manage remotely:

# mysql-uroot-p
