Common errors in starting... / sbin/nginx

To be replenished

Eliminate the wrong train of thought

1. Nginx-t, the simplest way to debug, check the configuration file syntax of nginx, and if there is no problem, return a message similar to the following

Nginx: the configuration file / data/wwwroot/nginx-1.17.1/conf/nginx.conf syntax is oknginx: configuration file / data/wwwroot/nginx-1.17.1/conf/nginx.conf test is successful

2. Turn on the log function of nginx

# error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info

Just remove the previous "#".

MySQL partial initialization parameter bin/mysqld-- initialize-- user=www-- basedir=/data/wwwroot/mysql-- datadir=/data/wwwroot/mysql/data considerations

The initialized password is saved in mysql_error.log under the log file (this file is the "log-error option" you defined in the my.cnf file)

Cat log/mysql_error.log | grep password

Modify MySQL password

Bin/mysql_secure_installation startup... support-files/mysql.server start # common errors in official startup scripts

Problem 1: when performing the mysqld initialization operation, the error message is as follows:

Bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

Solution: install the libaio runtime

Yum install libaio libaio-devel-y

Problem 2: when starting MySQL using the startup script included with MySQL, the error message is as follows:

Starting MySQL. ERROR! The server quit without updating PID file (/ data/wwwroot/mysql/data/blog.blacklinux.cn.pid).

Solution: check permissions

1. MySQL path permissions

Chown-R www.www / data/wwwroot/mysql # here is your MySQL directory

2. Check the my.cnf file

[mysqld] user=www # specifies the user port for running MySQL = 3306...PHP part of the essential library yum install-y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel compilation parameters. / configure-- prefix=/data/wwwroot/php-7.3.7-- enable-mysqlnd-- with-mysqli=mysqlnd-- with-pdo-mysql=mysqlnd-- enable-fpm-- with-fpm-user=www- -with-fpm-group=www-- with-zlib-- considerations for with-openssl

Use the configuration file that comes with the PHP source package

Mv lib/php.ini-production lib/php.ini

Copy the default ungenerated configuration file for PHP

Cp-an etc/php-fpm.conf.default etc/php-fpm.confcp-an etc/php-fpm.d/www.conf.default etc/php-fpm.d/www.conf

Modify the mysqli.default_socket option in php.ini

Mysqli.default_socket = / data/wwwroot/mysql/run/mysql.sock startup. / sbin/php-fpm common errors

Problem 1: start php-fpm to report an error, and the error message is as follows:

[root@localhost php-7.3.7] # sbin/php-fpm [05-Jul-2019 04:01:01] WARNING: Nothing matches the include pattern'/ lnmp/php-7.3.7/etc/php-fpm.d/*.conf' from / lnmp/php-7.3.7/etc/php-fpm.conf at line 143.[ 05-Jul-2019 04:01:01] ERROR: No pool defined. At least one pool section must be specified in config file [05-Jul-2019 04:01:01] ERROR: failed to post process the configuration [05-Jul-2019 04:01:01] ERROR: FPM initialization failed

Solution: generate www.conf

Cp-an etc/php-fpm.d/www.conf.default etc/php-fpm.d/www.conf

Question 2: Fatal error: Uncaught Error: Call to undefined function gzinflate ()

Solution: this is because the source code compiles php without zlib, so you can recompile with zlib.

Database operation

Take MySQL database as an example

Create database wordpress;grant all on wordpress.* to wordpress@'localhost' identified by '123456 firewall operation with flush privileges;

Add ports 80 (http) and 443 (https) to open to the public

Firewall-cmd-- zone=public-- add-port=80/tcp-- permanent command meaning:-- zone # scope-- add-port=80/tcp # add port, format: Port / communication protocol-- permanent # is in permanent effect. Without this parameter, the firewall is rebooted when it fails to boot. Systemctl restart firewalld.service starts automatically.

Empowering

Chmod + x / etc/rc.d/rc.local

Add the following to rc.local

/ lnmp/nginx/sbin/nginx/lnmp/mysql/support-files/mysql.server start/lnmp/php/sbin/php-fpm
