### --enable-fpm Enable php-fpm . --with-mysql and  --enable-gd-native-ttf   stay PHP7.3 To discard  --with-pdo-mysql Instead of --with-mysql, --enable-gd-native-ttf Parameter discard has no effect 

#PHP7.4 Version compilation error configure: WARNING: unrecognized options: --with-gd, --with-freetype-dir, --with-libxml-dir, --with-jpeg-dir, --with-png-dir   The reason is that these parameters are in 7.4 Version does not support 
# resolvent ：  Use these three parameters instead  --enable-gd --with-jpeg --with-freetype


5.make && make install


6. modify php The configuration file 

cd /opt/php-7.3.29

cp php.ini-production  /usr/local/php/lib/php.ini

cp php-fpm.d/www.conf.default   php-fpm.d/www.conf



 7、 ... and 、 Copy zabbix Front end to nginx Default web Catalog 

cd /opt/zabbix-5.0.13/

cp -a ui/* /usr/local/nginx/html/

To write systemd Service startup file , Easy to manage

# matters needing attention mysql 8.0 edition problem

# stay MySQL 8.0.11 in ,caching_sha2_password Is the default authentication plug-in , It's not what it used to be 
mysql_native_password. About the impact of this change on server operation and the compatibility of the server with clients and connectors 
 Information about , see also caching_sha2_password As the preferred authentication plug-in .
( Translated from https://dev.mysql.com/doc/refman/8.0/en/caching-sha2-pluggable-authentication.html）

 from 8.0.11 Since version , No longer like mysql5.7 As in previous versions , When setting the user password, the default authentication method is 
caching_sha2_password, If you find an upgrade mysql8.0.11 The original program cannot be connected mysql,
 Can be quickly in mysql command line client The client is set to mysql5.7 And previous versions of password authentication ,
 meanwhile MYSQL8.0.11 The way to change the password is not the same as before , The original order to partially change the password is mysql8.0.11 Next not available .
> use mysql  
> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY ' Your password ';  
> FLUSH PRIVILEGES;            

 Two ,mysql  The latest version is installed 8.0.11 After the user is created and authorized , Prompt for authorized users to connect to the database 
The server requested authentication method unknown to the client
 After consulting some relevant materials, it is found that it is due to the new version mysql Account password unlocking mechanism is inconsistent 
 terms of settlement ：
 Delete the created user and authorization ,
 find mysql Configure the file and add 
default_authentication_plugin=mysql_native_password
 Change to the original verification method , Then create a new user and authorize 
 or 
mysql -uroot -p
use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY ' Your password ';
