安裝nginx(做負(fù)載平衡)：

1、安裝prce(重定向支持)和openssl(https支持汹桦，如果不需要https可以不安裝他宛。)

?????? yum -y install pcre*? #

??????? yum -y install openssl* #

2、下載nginx

?????? wget http://nginx.org/download/nginx-1.9.9.tar.gz

3、解壓編譯安裝? ?

????? tar -zxvf nginx-1.9.9.tar.gz #? ?

????? cd nginx-1.9.9 #??

????? ./configure --prefix=/usr/local/nginx-1.9.9 --with-http_ssl_module --with-http_spdy_module --with-http_stub_status_module --with-pcre #? ??????? make && make install #

4何陆、nginx啟動(dòng)與停止

????? /usr/local/nginx-1.9.9/sbin/nginx #啟動(dòng)

????? /usr/local/nginx-1.9.9/sbin/nginx -s stop #停止

????? /usr/local/nginx-1.9.9/sbin/nginx -s reload #重啟

5、配置負(fù)載平衡

?????? vi /usr/local/nginx-1.9.9/conf/nginx.conf? nginx配置文件

?????? 只需要修改http{}之間的內(nèi)容就行了

?????? 設(shè)置服務(wù)器組：

????????????? upstream myServer{

????????????????????? server www.node1.com:80;? #這里是要做負(fù)載均衡的服務(wù)器地址1

????????????????????? server www.node2.com:80;? #這里是要參與負(fù)載均衡的服務(wù)器地址2

????????????? }

???????? 將請(qǐng)求指向myServer

?????????????????? location / {

???????????????????????? proxy_pass? http://myServer;

?????????????????? }

6豹储、負(fù)載權(quán)重

?????? 1-默認(rèn)輪詢

??????? 2-weight（值越大訪問(wèn)次數(shù)越多）

??????????????? 實(shí)例：server 192.168.0.14 weight=10;

??????? 3-ip_hash （每個(gè)訪客固定訪問(wèn)一個(gè)后端服務(wù)器贷盲，可以解決session的問(wèn)題）實(shí)例： ip_hash;? ? ? server 192.168.0.14:88;? ? ? ? ------------------------------------------------------------------? ? ? ?

每個(gè)設(shè)備的狀態(tài)設(shè)置為:

??????????? 1.down 表示單前的server暫時(shí)不參與負(fù)載

??????????? 2.weight 默認(rèn)為1.weight越大，負(fù)載的權(quán)重就越大剥扣。

??????????? 3.max_fails ：允許請(qǐng)求失敗的次數(shù)巩剖，默認(rèn)為1

??????????? 4.fail_timeout:max_fails次失敗后，暫停的時(shí)間钠怯。

??????????? 5.backup： 其它所有的非backup機(jī)器down或者忙的時(shí)候佳魔，請(qǐng)求backup機(jī)器。所以這臺(tái)機(jī)器壓力會(huì)最輕晦炊。 ----------------------------------------------------------------------------

?安裝MySQL5.6.29

???????????? 1鞠鲜、卸載mariadb（負(fù)責(zé)會(huì)和Mysql有沖突）

?????????????????? rpm -qa | grep mariadb #查看是否安裝mariadb

?????????????????? rpm -e --nodeps 名字 #不檢查依賴刪除

????????????? 2、解壓tar文件

??????????????????? tar -xvf MySQL-5.6.29-1.x86_64.rpm.tar #

????????????? 3断国、安裝

??????????????????? rpm -ivh MySQL-client-5.6.29-1.el7.x86_64.rpm #

??????????????????? rpm -ivh MySQL-devel-5.6.29-1.el7.x86_64.rpm #

??????????????????? rpm -ivh MySQL-server-5.6.29-1.el7.x86_64.rpm #

??????????????????? 安裝目錄：/usr/share/mysql

???????????????????? 配置文件：/usr/share/mysql/my-default.cnf

???????????????????? 復(fù)制 cp /usr/share/mysql/my-default.cnf /etc/my.cnf（去修改my.cnf）

????????????? 4贤姆、啟動(dòng)MySQL更改密碼

??????????????????? cat /root/.mysql_secret #查看系統(tǒng)隨機(jī)的密碼#

???????????????????????????? The random password set for the root user at Fri Apr? 1 12:12:29 2016 (local time): Z9vv1v9AwaoFmlJo #Z9vv1v9AwaoFmlJo就是密碼

???????????????????? service mysql start #啟動(dòng)

????????????????????? mysql -uroot -pZ9vv1v9AwaoFmlJo #進(jìn)入mysql命令模式

????????????????????? set password=password("root"); #更改密碼為root

????????????????????? use mysql; #進(jìn)入mysql數(shù)據(jù)庫(kù)

????????????????????? GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION; #添加遠(yuǎn)程root用戶密碼root登錄#無(wú)法連接請(qǐng)關(guān)閉防護(hù)墻

5、忘記密碼

??????????????? service mysql stop #關(guān)閉

???????????????? mysqlmysqld_safe --skip-grant-tables #開(kāi)啟后臺(tái)mysql

???????????????? mysql #進(jìn)入mysql命令模式

??????????????? use mysql; #進(jìn)入mysql數(shù)據(jù)庫(kù)

???????????????? UPDATE user SET password=password("root") WHERE user='root'; #更改密碼

???????????????? flush privileges; #立即生效

???????????????? exit; #退出并重啟mysql

6并思、主從異步同步在

??????????????? 主服務(wù)器上修改MySql配置文件(/etc/my.cnf)

?????????????????????? 在[mysqld]下添加以下配置：

??????????????????????????? server_id=1 log_bin=mysql-bin 指定二進(jìn)制日志文件的名稱

??????????????????????????? 重新啟動(dòng)mysql服務(wù) show master status;查看 mysql-bin.000001 并記錄

??????????????? 在從服務(wù)器上修改MySql配置文件(/etc/my.cnf)

?????????????????????? 在[mysqld]下添加以下配置：

????????????????????????????? server_id=2 log_bin=mysql-bin? 指定二進(jìn)制日志文件的名稱

????????????????????????????? relay_log=relay_log 指定中繼二進(jìn)制日志文件的名稱

????????????????????????????? log_slave_updates=1? ? ? ? ? ? ??

?????????????? read_only=1

??????????????????????? 重新啟動(dòng)mysql服務(wù) 在mysql中運(yùn)行：

??????????????????????????????? (1)stop slave;

?????????????????????????????? (2)change master to master_host='192.168.199.247',master_user='root',master_password='root',master_log_file='mysql-bin.000001',master_log_pos=0庐氮；

??????????????????????????????? (3)start slave;

???????????? show slave statusg; 來(lái)檢查是否成功,如果slave_io_state為：Waiting for master to send event，slave_io_running宋彼、slave_sql_running都為YES

----------------------------------------------------------------------------

安裝Apache2.4.18弄砍、

???????? 1、解壓

???????????????? tar -zxvf httpd-2.4.18.tar.gz

????????? 2输涕、進(jìn)入目錄編譯并按裝解決報(bào)錯(cuò)：

????????????????? 下載：? ?

???????????????????????????? wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz? wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz? ? ? wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip? apr not found問(wèn)題：? ?

???????????????????????????? tar -zxf apr-1.4.5.tar.gz? #? ?

???????????????????????????? cd? apr-1.4.5? #? ?

???????????????????????????? ./configure --prefix=/usr/local/apr? #? ?

????????????????????????????? make && make install? #??

???????????????? APR-util not found問(wèn)題：? ? ??

???????????????????????????? tar -zxf apr-util-1.3.12.tar.gz? #??

????????????????? pcre問(wèn)題：? ?

???????????????????????????? unzip -o pcre-8.10.zip? #

???????????????????????????? cd pcre-8.10? #

????????????????????????????? ./configure --prefix=/usr/local/pcre #make && make install #進(jìn)入目錄編譯并安裝cd httpd-2.4.18/ #./configure --prefix=/usr/local/apache --enable-module=shared --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre? #make && make install #

?????????????? 3音婶、啟動(dòng)與停止/usr/local/apache2/bin/httpd #啟動(dòng)

??????????????????? /usr/local/apache2/bin/httpd -k stop #停止

?????????????? 5、開(kāi)啟rewrite_module模塊
