Linux系统架构----LNMP平台部署中部署wordpress
Linux系统架构----LNMP平台部署中部署wordpress
一、LNMP的概述
- LNMP为Linux平台，Nginx web服务软件，mysql数据库软件，PHP编辑语言
- LNMP系统架构相对于LAMP的优点是LNMP比较节省内存，主要支持静态请求，但在访问量大的时候php-fpm容易僵死，容易发生502 bad gateway错误，LAMP适合处理动态请求
二、Mysql的安装
- 二进制部署Mysql
[root@mysql ~]# cat install_mysql.sh #!/bin/bash . /etc/init.d/functions SRC_DIR=`pwd` MYSQL='mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz' COLOR='echo -e \E[01;31m' END='\E[0m' MYSQL_ROOT_PASSWORD=magedu check (){ if [ $UID -ne 0 ]; then action "当前用户不是root,安装失败" false exit 1 fi cd $SRC_DIR if [ ! -e $MYSQL ];then $COLOR"缺少${MYSQL}文件"$END $COLOR"请将相关软件放在${SRC_DIR}目录下"$END exit elif [ -e /usr/local/mysql ];then action "数据库已存在，安装失败" false exit else return fi } install_mysql(){ $COLOR"开始安装MySQL数据库..."$END yum -y -q install libaio numactl-libs ncurses-compat-libs cd $SRC_DIR tar xf $MYSQL -C /usr/local/ MYSQL_DIR=`echo $MYSQL| sed -nr 's/^(.*[0-9]).*/\1/p'` ln -s /usr/local/$MYSQL_DIR /usr/local/mysql chown -R root.root /usr/local/mysql/ id mysql &> /dev/null || { useradd -s /sbin/nologin -r mysql ; action "创建mysql用户"; } echo 'PATH=/usr/local/mysql/bin/:$PATH' > /etc/profile.d/mysql.sh . /etc/profile.d/mysql.sh ln -s /usr/local/mysql/bin/* /usr/bin/ cat > /etc/my.cnf <<-EOF [mysqld] server-id=1 log-bin datadir=/data/mysql socket=/data/mysql/mysql.sock log-error=/data/mysql/mysql.log pid-file=/data/mysql/mysql.pid [client] socket=/data/mysql/mysql.sock EOF [ -d /data ] || mkdir /data mysqld --initialize --user=mysql --datadir=/data/mysql cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld chkconfig mysqld on service mysqld start [ $? -ne 0 ] && { $COLOR"数据库启动失败，退出!"$END;exit; } sleep 3 MYSQL_OLDPASSWORD=`awk '/A temporary password/{print $NF}' /data/mysql/mysql.log` mysqladmin -uroot -p$MYSQL_OLDPASSWORD password $MYSQL_ROOT_PASSWORD &>/dev/null action "数据库安装完成" } check install_mysql [root@mysql ~]# bash install_mysql.sh 开始安装MySQL数据库... 已安装: libaio-0.3.112-1.el8.x86_64 创建mysql用户 [ 确定 ] Starting MySQL..
